Mercedes-Benz Unimog U4000 First Drive

"In this gear, the maximum speed is 80 meters per hour," Siegfried Burow tells me. I can hear the U1450's diesel engine making noise, but our forward progress is imperceptible. Again, we're moving at 4 feet per minute. I should explain that this particular Unimog has been outfitted with a set of ultra-low gears, bringing its total up to 32 speeds -- eight forward, eight low, eight ultra-low, and eight reverse. Why eight reverse? "Well, let's say you have to back up a train," Karlheinz Guttman explains with a straight face. "You might want to start slow and then speed things up." It's true, you might. 

The real answer to the question "Why?" is that since it was developed in 1946, the Unimog (short for Universal Motor Geraet, or Universal Motorized Machine) has always been about maximum functionality. Intended to be a replacement for a conventional tractor, Unimogs never really set the agricultural world on fire. Farmers, it seems, are just fine with their tractors. Militaries the world over, however, absolutely love them some Unimog because of its ability to do damn near everything. Like towing trains, moving at speeds as slow as 4 feet per minute or -- most important -- being able to get to the same places as a tank. 

 Guttman and Burow are curators of the Unimog Museum in Gaggenau, Germany, halfway between Stuttgart and Strasbourg, France, home to the original Unimog factory. While small, the museum does house a great collection of Unimogs, including Prototype #6, the earliest surviving Unimog there is. (Fun fact: The original track was 127 cm wide because that's the same as two rows of potatoes.) The collection also contains several early 400 series 'Mogs, including a bafflingly cute Swiss fire truck with a 40cm wheelbase extension, because a Swiss law mandated that all fire vehicles must be able to seat eight people.

What's so incredible about the prototype is that all the key aspects that define Unimogs to this day are present in the original. First are the portal axles. Instead of the ends of the axles entering the center of the wheel, the shafts enter the top of the wheels and are then geared down. This effectively doubles the truck's ground clearance. The next key trait is the hyper-articulating suspension. Each solid axle is able to rotate up to 30 degrees in either direction. (The torque tubes fit into the transmission via a ball joint.) Moreover, the engine and transmission are attached to the frame only in three places, on rubberized mounts. When called for, this setup provides extra twisting ability. 

The final piece of the Unimog puzzle are the unique transmissions. Even the earliest versions provided for several forward speeds (six in 1946!) and multiple reverse gears. Prototype #6 had two, whereas modern 'Mogs have up to eight. Reverse on a Unimog works similarly to low gears (transfer case) on traditional 4x4s. There's a second lever (on manual trucks) for selecting forward or reverse. All you need do is clutch in and throw the lever, and suddenly you've gone from fifth gear to fifth in reverse. They also have the from-the-factory ability to accept geared power takeoff units to run more than 3500 implements, from snow blowers to seed spreaders to grass trimmers. 

Behind the museum is a small yet severe Unimog parcourse with an idling 2012 U4000 doka, or double cab. Burow was in the driver's seat and eager to give me a run around the course. Guttman gave me a copy of "Faszination Unimog Museum," a book about the museum's history that happens to contain a photo of Burow building the parcourse. Who better to take me around? Two-dimensional images don't do justice to the severity of the course and its obstacles. From my perspective, the U4000 scaled a wall, climbed a staircase, drove on its door, and rode over boulders. Then, Burow ran the entire thing backwards. The mighty 'Mog didn't even sweat, let alone even kind of get stuck. I was having so much fun, I invited the photo and video crew inside to have a couple laps. As far as I know, they're still smiling.

After the museum, we went to an abandoned rock quarry near Rastatt that's been converted into a Unimog playground. "Wonderland" is more apt. There were 45-percent grades, 4-foot-deep water obstacles, rocks, mud pits, tortuous trails, and specially designed piles of concrete to show off the fact the driver-side front wheel can be 1 meter off the ground. At the same time, the passenger-side rear wheel can also be 1 meter up. All too often, trucks and SUVs are described as having the ability to "go anywhere." But I can't think of another production vehicle I've ever been in that could do one-quarter of what the U4000 did.

2013 Mercedes-Benz S65 AMG

Mercedes-Benz sells seven different models of its flagship S-Class sedan in the States. Look past the entry-level S400 Hybrid and the standard V8-powered S550 models. The four-door at the pinnacle – squashing the amazing S63 AMG and twelve-cylinder S600 as it steps over them – is the bordering-on-preposterous twin-turbocharged twelve-cylinder S65 AMG seen here.

"Excessive" is an understatement, as the S65 AMG leaves little to want. Tucked up front is a hand-assembled 60-degree 6.0-liter V12, force-fed air by twin blowers to develop 621 horsepower and 738 pound feet of torque. All of the mind-blowing power is sent through a robust five-speed automatic to the rear wheels where it seems utterly unchallenged by the sedan's curb weight of 5,082 pounds – the four-door will bust through the benchmark 60 mph barrier in 4.2 seconds and pull all the way to its electronically limited top speed of 186 mph.

Few will ever have the opportunity to see an S65 AMG in the flesh, let alone spend an hour alone with one, so I leapt on the opportunity. Upgraded from the standard trim, this particular test car was an even scarcer bespoke "Designo" model, with exclusive matte paint, custom shades of soft leather and glossy piano black trim. Pricing, as they say, is available upon request.

Despite its omnipotence, the S65 looks rather low-key and almost indistinguishable from its siblings. Observers will note the "V12 Biturbo" badging on each front quarter panel and the "S65" on the rear decklid. Those with really good eyes will catch the slight difference in the horizontal slats on the S65's front grille (three twin-parallel slats, upgraded from four thick bars). Most all of the other sporty cosmetic enhancements are shared with the S63 AMG.


It is impossible to defeat the traction control on the S65 AMG, meaning mile-long burnouts aren't going to happen. While acceleration off the line was dizzying, the real fun happened above 50 mph when the explosive power under the hood spooled to its full potential (it's a treat to watch the traction control light blink at highways speeds). An illegal coast-to-coast run at 150 mph would be joyful and effortless, but I would hate to foot the fuel bill (or pay the fines).


Of course, the S65 will never feel as nimble as smaller sedans, but its active suspension was more than competent through every series of curves I tossed it into. There is no getting around two-plus tons of mass, but the aggressive staggered tire package (255/35ZR20 and 275/35ZR20) provided plenty of grip at the limit. The unique twin sliding-caliper brakes fitted over cross-drilled rotors effortlessly bled off the speed with very good pedal feel. It is a very large and comfortable luxury sedan, yet it is still very entertaining to drive - much to my surprise.


Those who couldn't care less about the S65's mechanical brilliance will find plenty to soothe their souls inside the cabin, as the opulence of a standard S-Class sedan has been turned up a full revolution on the dial. Supple seat leather is stitched, quilted and perforated (heated and cooled too) and the trim is polished to a mirror-like finish. Passengers in the second row will find leg crossing room, power seats and video entertainment. The cabin smells even better than it looks. I can't wait to see how the next S-Class looks and feels inside.

2014 Mercedes-Benz S-Class: Mercedes-Benz Previews the Interior Ahead of its New York Debut





Mercedes-Benz is going to officially take the wraps off the next-generation 2014 S-Class at the New York Auto Show next week. We've seen several spy photos of the new S-Class sedan, which shows a sedan that will not be a huge departure stylistically. While we wait for its official debut, Mercedes-Benz has released a batch of photos of the interior of the new S-Class.

Mercedes-Benz has dubbed the new S-Class the "best best automobile in the world." The automaker also says that goal for the new S-Class was "perfection to the last detail" with the final result being called "The Essence of Luxury." The 2014 S-Class's interior is full of new first like the redesigned display that extends in front of the driver. It replaces the traditional instrument cluster and combines numerous other functions. Also the entire display appears to be free-floating, an impression reinforced by "corona effect" ambience backlighting. Two high-resolution color displays in 8:3 format with a screen diagonal of 12.3 inches form the new information center in the S-Class. The left-hand display performs the functions of the previous instrument cluster, providing the driver with all relevant information. The right-hand display allows the convenient control of infotainment and comfort functions.

The seats also get a new "energizing" massage function that uses the "hot stone principle" and features a unique massage function with 14 separately actuated air cushions in the backrest, as well as an integrated warming function. There is a choice of six massage programs, two of them using the warming function. The new "warmth comfort package" heats the steering wheel, armrests and door center panels in the front and rear.

Three new features improve safety in the rear: in the belt buckle feeder an electric motor automatically raises and lowers the buckle. The belt bag is an inflatable seat-belt strap that is able to reduce the risk of injury to passengers in the rear in a head-on collision by lessening the strain on the ribcage. The reclining seat is fitted with a cushionbag as standard. This prevents the occupant from sliding under the belt in the event of an accident.

Another interesting new feature is the "air-balance package" that features a system that can individualize the smell of the vehicle interior. It neither changes the interior smell permanently, nor are perfume molecules deposited on fabric surfaces or clothing.

The new S-Class is also the first vehicle worldwide to offer a genuine multi-user system for entertainment functions. This means that there is independent access to the media sources of the entertainment system from any of the four seats - i.e. radio, TV, internet, navigation, DVD player and USB-connected devices.

50th Anniversary of the Pagoda SL -- Mercedes-Benz Classic Vehicles


Penned by designer Paul Bracq, the W113 SL had big shoes to fill: it had the incredible task of succeeding the original and instantly iconic 300 SL Gullwing. But you can't copy a legend, so Bracq designed one of his own. Straight lines replaced curves and a low-slung roof was replaced by a high top design that gave the car its nickname: the Pagoda. This year marks the 50th anniversary of this seminal design and we're celebrating it non-stop!

Epic Drive: 2013 Mercedes-Benz G65 AMG In Sweden


None of this was ever supposed to happen. Not the Mercedes-Benz G65 AMG, and certainly not a five-day road trip from Copenhagen, Denmark, to the Swedish Arctic Circle with 24 Hours of Le Mans winner Justin Bell and little old me. A generation ago, Lamborghini dropped the Countach's V-12 engine into a failed military vehicle and called the result the LM002. The Sant'Agata concern sold 328 of them in an 8-year period. Very few OEMs have bothered with a 12-cylinder SUV since then. Audi had its special-order-only Q7 V-12 TDI (now out of production), and BMW once shoehorned its LMS 6.0-liter V-12 into an X5 as a publicity stunt. Recently, Bentley and Lamborghini have been toying with the idea of selling 12-cylinder SUVs  -- the W-12-powered Bentley EXP 9F and the Aventador-engined Lamborghini Urus -- and both may have been green-lighted for production by the time you read this. Or not. AMG reportedly hemmed and hawed for years over the decision to build the 612-hp, 6.0-liter twin-turbo V-12 brute. When it finally did, the thinking was that AMG would sell around 500 units in 10 years. More than 400 were sold in the first six months. 
 "The Germans don't want you driving the G65," I'm informed by a Mercedes-Benz North America PR honcho. "They think you'll be upset by the poor gas mileage and would rather you went in a G63." The G63 AMG is the 5.5-liter, twin-turbo version of the G-Wagen that's actually sold here in the States, another reason they didn't want an American journalist in said ultra-rare truck. The G65 is not sold here because Mercedes felt the cost and complication of certifying one for U.S. roads (i.e., crash testing) weren't worth the hassle. Though in light of how the big G is selling around the world, I'm sure they're rethinking that strategy now, because, holy cash cow, Batman. The Gelaende-wagen, more commonly called the G-Class, first showed up in 1979. Meanwhile, the big, twin-turbo M285 engine is already in production for use in AMGs such as the S65, CL65, and SL65.
Another reason for the reluctance to let moi have at the baddest production G-Wagen the world has ever seen is that Mercedes-Benz has exactly one G65 press car in its stable, and you're looking at it. After much haggling (fine, begging), it was agreed that I could drive the Big Daddy G. 
Why Sweden? A few months ago, while riding around in a prototype version of the new E63 AMG S Model 4Matic, AMG CEO Ola Kallenius offered me the chance to visit AMG's Winter Driving Academy on a frozen lake near the town of Arjeplog in Sweden. Hey, it's good to know the king. While that sounded like loads of fun, I told Ola it would be even better if we could drive up to his lake. Of course, we would need something sufficiently burly to deal with extreme northern latitudes of Lapland, as well as something luxurious (and, dare I say, decadent) enough for my good buddy and travel companion Justin Bell. The truth is that I've always wanted to do something epic in a G-Wagen, and heading up through the heart of Scandinavia in the dead of winter just made sense. So our trip began in Denmark, the only Scandinavian country I'd previously visited. We quickly learned a couple of things: The first is that, even in late January, the denizens of Copenhagen love riding their bicycles. The second is that Danes seriously admire the G-Wagen, at least compared with their Swedish neighbors. I think a yellow Ferrari would have been less conspicuous. Copenhagen was just our embarkation point, and after a dinner featuring herring five ways, we set off for points farther north. 

Copenhagen to Stockholm was by far the least interesting portion of our trip. Justin kept accurately complaining that the weather looked like England: cold, wet, and bleak. Most of that 400-plus-mile day was spent with me explaining the history of the G-Class to Justin, as he'd never so much as been in one before. I've driven a few. Just days before I showed up in Copenhagen, Mercedes let me play around with a G63 AMG (same basic truck, but with the M157 twin-turbo 5.5-liter V-8) in Miami to get familiar. While I was in Miami, Florida experienced its coldest night of the year, and the temperature dropped to 58 degrees. I realized then I'd never driven a G in anything approaching bad conditions, let alone taken one off pavement. Justin added, "I mostly see these in Beverly Hills with mothers dropping their kids off for soccer practice. I always thought their capability was more folklore than truth." I assured him that the military in 35 countries use the G-Wagen, including the U.S. Marines. I also assured him that three locking differentials meant the G65 would essentially turn into a tractor off-road, even with the quilted, two-tone Designo leather and quad sidepipes. But all that good, dirty stuff would have to wait until after Stockholm.

Steinbeck never mentioned how sometimes the best-laid schemes of mice and men actually work out. Trying to be as new-media-savvy as possible, I contacted the people behind Curate Sweden. Each week, the country of Sweden's Twitter account is handed over to a different citizen. Because the individual Swede gets to do whatever he or she likes with the account, Curate Sweden can't tell him/her what to do, or to help us out in any way. However, I was able to get in touch with a curator named Kristin Zetterlund, and she agreed to show Justin and me around Stockholm. Then, just days before we left, Kristin wrote me that the day we were to show up was the end of Fashion Week Stockholm, and she had to cover the shows for work. I contacted Mercedes and asked if they were behind this particular Fashion Week. Yup. Justin and I rolled the dirty G65 up to the front of the posh Berns Hotel, were treated like visiting dignitaries while checking out the latest in Swedish haute couture, and even met up with the lovely Miss Zetterlund. All in all, a picture-perfect night. Angus MacKenzie has a saying: "There's only one vehicle  that can pull up to the opera caked in mud: the Range Rover." I'd like to add the G65 to that list. But fashion shows and fine dining were not the reason we brought Big Papa G to Sweden.

Things finally got a little harsher and weirder once we left Stockholm and began trudging north up the E4. First of all, the sleet and rain turned to actual snow. Second, we passed a sign that read, "Welcome to China -- 4 km." Sure enough, for no discernible reason whatsoever, we stumbled across a Chinese-themed rest stop, complete with a miniature Great Wall and a 20-foot Confucian good luck statue. Of course, the improbable China complex seemed almost normal once we reached the city of Gaevle to check out the world's largest Yule goat, aka the Gaevle Goat. Only problem is that someone had burned it down. In fact, the Gaevle Goat has been burned down 26 times since it first appeared in 1966. Every year, the merchants of Gaevle erect a 40-foot straw goat (Guinness certified as the world's largest), and every year, attempts are made to burn it, break it apart, or throw it into the river. My favorite Gaevle Goat destruction story has to be the year two men dressed respectively as Santa Claus and a gingerbread man shot flaming arrows into the goat. This past year's giant Yule goat was burned down on December 12, just 10 days after it was built. All Justin and I found were pieces of the goat's charred necklace lying in a field of snow. Speaking of snow, the roads were now absolutely covered in the stuff. Justin hails from the south of England, and I was born and raised in Southern California; we both currently call Los Angeles our home. Meaning we know very little about snow. (It's also why we thought driving into a 3-foot-high snow bank was a grand idea.) But even on some modest Dunlop all-season rubber -- instead of the rubber-band-thick summer tires most U.S.-bound G-Wagens roll on -- I can't remember either of us having any sort of traction-related trouble with the nearly 6000-pound G65. The big AMG shrugged off the worsening conditions exactly as your 12-year-old self expected the ladder-frame beast would. Even Justin was coming around to the prowess of the G-Wagen, though he seemed to enjoy the potent seat heaters as much as he did the truck's copious capability. We stopped at Lake Storsjoen just outside of Oestersund, the third largest city in Norrland (northern Sweden), to see if we could locate Storsjoeodjuret, Sweden's version of the Loch Ness Monster. No luck on that front. However, while standing on the dock looking out over the gorgeous frozen lake, I noticed for the first time that it was really and truly cold. The G65 told us it was -11 C, or 12 degrees Fahrenheit. From Oestersund, it was still another 300 miles farther north to reach AMG's frozen lake in the Arctic Circle. Well, what we assumed was the Arctic Circle. As it turns out, AMG's most excellent lake just outside of Arjeplog lays a few tenths of a degree below the Arctic Circle.
But the lake was next -- and what a lake! Acres and acres of nothing but 2-foot-thick ice and a bunch of AMGs on studded tires. Had we not been delayed a day (Justin had been obligated to announce the 24 Hours of Daytona race for the Speed Channel), we would have been able to participate in two glorious days of ice drifting. As it stood, we had but one morning, and it was 26 degrees C below zero, the coldest temperature we'd see. Neither Justin nor I had ever done ice driving before, so naturally we leapt right into an E63 sedan, the most powerful car on the ice. I'm sure it won't shock any of you to learn that Justin drifted better than I. He's a car control expert and former owner of his own driving school, after all. However, I did pretty OK, kicking the back end out and applying enough opposite lock to look kind of fancy for several seconds at a time. We then switched over to a much smaller course and an SLK55. I had explained to Justin that the diminutive AMG roadster with its naturally aspirated 429-hp V-8 is the best drift machine currently on sale. Within maybe two corners, he was in complete agreement. We unfortunately had to skip the C63 so we could take the G65 on a proper off-road course. With just the center differential locked, the V-12 SUV didn't even break a sweat. There was even one tight corner where the G65's near-ludicrous 738 lb-ft of torque came in handy, as you had to quickly nail the throttle to whip the back end around to avoid making a three-point turn. Brilliant fun. 
But as much fun as we were having at the AMG Academy, we still weren't above the Arctic Circle. A quick check of photographer Julia LaPalme's French-language map told us we had 50 more miles left to trek. If our Epic Drive was going to live up to its name, we simply had to go -- even if doing so meant missing half a day of playing on ice. The thing that grabbed me hardest about Sweden in full winter bloom is that the farther north we went, the more otherworldly the terrain became. We saw rocks frozen white, trees covered in so much snow that their tops were bent down to the ground, and lakes so cold they glowed blue. The scenery was growing both more gorgeous and more bizarre with each passing mile. We drove through frozen fog, and I swear that, on more than one occasion, the air simply froze. I was behind the wheel, and Justin was on my iPhone, watching a GPS app that told us our position. "66 degrees, 27 minutes," he announced. The magic numbers we needed were 66 degrees, 33' 44". I pushed the G65, flying along at 80 mph on perfectly white, frozen roads. "66, 29," Justin barked. Then suddenly we saw the sign. Polcirkein. Napapiiri. Arctic Circle. Cercle Polaire. Polarkreis. We'd done it. Justin and I had driven one of the rarest SUVs on Earth 1483 miles to a place very few people get the chance to visit. We were absolutely thrilled. As for the G65, we finally found its element.

2014 Mercedes-Benz CLA250 Sport





We got overexcited when the W203 Mercedes-Benz C-Class sedan came out in 2001, calling it the "Baby Benz" when it really wasn't. We knew that, too, but our enthusiasm for a model more like the old 190 of the '80s was so strong that we were willing to stretch the first-gen C-Class to fit that mold. Today, the C-Class has done what all German premium cars do: grown in size. In this case, grown to satisfy the market intentions of the previous E-Class.  


There was the tall A-Class sold from 1998 through 2010, but we never considered that a serious small Benz in the proper spirit, nor was it ever offered in the US. Regardless, we've been craving a smaller, premium, sexy sedan all the while.

As you read this, Mercedes-Benz has just unveiled, with great fanfare at this year's Geneva Motor Show, the production CLA-Class. We saw the car at the Detroit Auto Show in January, and the Concept Style Coupe that led to the CLA was first seen in China at the 2012 Beijing Motor Show. The CLA – a.k.a. "the baby CLS" – is finally here and we've driven it.

The name CLA stands for "Coupe Light A-Class" in keeping with the CLS that set the four-door coupe standard. Think of it simply as the A-Class that we get. The CLA arrives in European markets this April and will compete with the future BMW 2-Series Gran Coupe sedan and Audi A3 sedan, both of which will be introduced over the next twelve months.

The US will get the top trim CLA250 only, with front-drive models arriving in September of 2013 and 4Matic versions coming by Spring 2014. Some of us may be irked by the exclusion of smaller gas and diesel engines from the US market. Some others will dislike that there is no six-speed manual offered (the standard transmission in all markets outside of North America), only the somewhat-new 7G dual-clutch seven-speed.

As soon as we heard that all CLA250s destined for the United States were to come standard with a lowered sport suspension, we were all over spending more time with the front-wheel-drive sport chassis test cars, which is what you see here.

The interior you see on this CLA250 Sport is part of the limited-run Edition 1 trim, which gets the sport leather-dressed Neon Art performance seats with yellow stitching, the very nice blackened AMG design 18-inch alloys, the aforementioned sport chassis, AMG-look aero bits, bi-xenon headlights, and synthetic leather-covered dash and console surfaces. The US will only receive 750 units of the CLA250 Edition 1, though none offering a manual.
So we took off through the rustic, hilly wilds of southern France, much like a bat out of Hell, or at least as hellishly batty as this most aggressive CLA model can run. The first order of business was to simply feel the calibration of the sport chassis in motion. This particular calibration lowers the CLA some 0.8 inches in the front and 0.6 inches in back. Throw in the electro-mechanical steering and Merc's Direct Steer technology, and we were optimistic about how things would turn out over 200 miles of twisty French two-lanes.
On these older driving surfaces, the Euro-style road noise came through easily via the 18-inch 225/40 Continental ContiSportContact5 run-flats that come equipped with the sport chassis. We enjoyed ourselves – a lot – at medium-to-quick speeds, but at slower around-town velocities, the tires thwacked us every time an imperfection or sewer head popped up. That's fine for those who opt for it, but equipping all CLAs in America with this default setup? Not a bullet-proof plan, we thought.

Mercedes project leader for compact cars, Hans-Georg Engel, responded frankly to our questions regarding this issue. Apparently, the plan is shifting as we speak. Now the logic is to bring over both the sport and comfort chassis setups. For now, that means still having the sport chassis as standard and the comfort setup available for order. But will it be offered by dealers as a no-cost option? This last detail is still TBD. Or the comfort calibration could, down the road, be standard and the sport chassis become part of a more aggressive sport package option. Call us wusses, but this re-thinking seems right if Mercedes wants to sell a lot of CLAs in the US.
 Engineer Engel also shared with us that, seeing as part of the CLA's good looks and kinship to the CLS rests on its lower stance, a new setup could be formulated in time for US deliveries that essentially combines the comfort dampers with the shorter sport springs. It would require more than just a switcheroo, but we're most in favor of this alternative. The other wish-list item is some simpler form of optional adaptive suspension, a suggestion Engel pretty clearly supported, provided it doesn't push up the price of the CLA to conflict with base C-Class trims.
While we did just get finished harping on about the sport suspension's roughness, once we got out on wide open roads with hairpins, bends and the like, this chassis tune showed that it was both capable and smooth – even on those brick-like 18-inchers. Understeer was minimal, weight transfer was very good, and we felt no untoward torque steer while punching the throttle coming out of turns. This was reassuring, seeing as the CLA is 1.5 inches longer and a little wider than a C-Class, while sharing the 2.4-inch-shorter wheelbase of the A-Class, along with the A's slightly narrower tracks. Weighing 150 pounds or so less than the most equivalent C-Class sedan also helps its dynamics.

Then there's the feel coming from the motor and software of the electromechanical steering system provided by Jtekt in Japan. On the more hectic sections of road, there was less time to notice the action of its thinking and re-thinking process. Where it really stood out, though, is through longer curves with constant or decreasing radii; the feel is of the trajectory being instantaneously and subtly remapped and executed many times, and so lacking the smooth and constant steering angle feel we're accustomed to. The real help here comes from the re-engineered transverse "M270" 2.0-liter four-cylinder engine, with an ICSI turbocharger good for 14.5 psi of constant maximum boost pressure. The power is a pretty universal 2.0T-like 208 horsepower, while the torque raises its game nicely to 258 pound-feet between 1,200 and 4,000 rpm. Our other pal, Mr. Guido Vent in charge of gas engine development on smaller Mercedes vehicles, tells us that there is an unadvertised overboost effect during kickdown with one's foot to the floor, which results in roughly 13 more hp and 15 more lb-ft of torque for brief bursts.

On these test routes, we had several opportunities to try out this overboost effect for passing maneuvers and we can say the powertrain pulls pretty dang well throughout the middle rev range. 0-to-60-mph acceleration in the CLA250 Sport should happen in 6.5 seconds or less, according to Mercedes, with top speed set at 149 mph. Fuel mileage, meanwhile, is seen as roughly five-percent better than in the larger C250 Sport sedan with 1.8-liter turbo, so around 23 miles per gallon in the city and 33 mpg highway.
Though the road noise through the Contis was noticeable, the CLA's world record low aerodynamic resistance (for a series production car) of 0.22 coefficient of drag in the Euro-trim CLA180 BlueEfficiency only rises to 0.23 for the rest of the models in the CLA catalogue. Not since we drove GM's EV1 with a CoD of 0.19 have we felt so much as though we were slipping through the air. Mercedes aerodynamics expert Patrick Höfer says simply, "Put the trunk on any vehicle and air turbulence diminishes quite a bit." Designers and engineers worked with aerodynamicists for the CLA more than is usual with other models. Coefficient of drag on the A-Class hatchback, in fact, is 0.27 and moves to 0.26 on the BlueEfficiency model – just to show the major leap in turbulence versus the knife-like CLA numbers. As a result, wind noise around the outside of the CLA's cabin is nearly not there.

As this form follows pretty dramatically its aerodynamic function, we can get right into the design. We enjoy the A-Class styling a bunch already, and every nuance from adding the trunk for the CLA is a pleasing one. That is, all except the tumble-home on the sheet metal at the very rear that involves the rear fenders, taillight elements and the trunk lid. Those rear corner zones are not as elegantly executed as the rest of the CLA, though each piece taken on its own is quite elegant. The chief culprit as we see it is the elevation of the rear deck lid, done thus for optimal aerodynamic effects. Pooching up the integrated and curved ducktail lip spoiler was needed to get the CLA's extraordinary 0.23 CoD. Regardless, the CLA's profile view is a fetching one.
 The in-cabin experience of the CLA stresses sportiness over all else, particularly on our Sport trim model. Rear headroom does suffer somewhat versus the C-Class sedan but is nonetheless livable. We wished for a sport exhaust sending some emotions back into the cabin, but all things in due time, we're certain. Looking at trunk space versus the C-Class sedans, they are just about identical at a US-rated 12.4 cubic feet, and the CLA rear seat backs are easy to flop forward and put back.

Mercedes-Benz has a small, premium feeling sedan we can work with happily in the CLA, and we're eager for the more interesting CLA45 AMG that will debut later this month at the New York Auto Show. There are improvements to be made in some areas that would make the non-AMG CLA a knockout hit in this segment, including a more inclusive suspension strategy to sell the car to more people, improving the feel of the electromechanical steering and Direct Steer, and further refinement of the 7G DCT for snappier shifts when desired.

The substance of the CLA message is there for now: This is a good and solid baby Mercedes sedan with above average build quality, great ambitions and looks that fit the established brand image worldwide.
