First Drive: 2012 Mercedes-Benz C-Class

The Baby Benz Becomes More Like Its Big Brothers

2012 Mercedes-Benz C-Class

When it comes to automobiles, money is usually the limiting factor. Endowed with unlimited dough, who wouldn't drive their dream car?

For those inclined toward luxury, the full-size Mercedes-Benz S-Class coddles its drivers with massive comfort and technology that compensates for nearly every common human frailty exhibited behind the wheel. The S-Class, however, remains beyond the means of most drivers.

Developed to make three-pointed quality, safety and luxury more attainable, the W 201 sedan was introduced by Mercedes-Benz in 1982. Known as the 190, this compact sedan stands as the direct forerunner of the C-Class. Some 8.5 million sales stand as M-B's commercial proof of concept over four generations. And the way things are going, those sales are set to continue.

Continue reading First Drive: 2012 Mercedes-Benz C350 Sedan... 

The 2012 C-Class is not an all-new car, but instead a revised 204 series (introduced in 2007). What's new? For the U.S. market we get refreshed front and rear styling, three more-efficient engines, a new gearbox, a revised interior and driving aids previously only available on M-B's more expensive models, including Lane Keeping Assist, Brake Assist, Adaptive Highbeam Assist, Blind Spot Assist and Parktronic. And yes, this means no diesels for us. No manual gearboxes, either, but that's not so surprising.

All the engines reside under a new aluminum hood and behind a facelifted nose featuring new headlights. Around back, new LED taillamps complete the visual modernization.
 
Powertrain details begin with the fact that our three new engines all run direct fuel injection. The 1.8-liter turbocharged four-cylinder makes 201 horsepower and 229 pound-feet of torque, and is available in the rear-wheel-drive C250. Those wanting all-wheel drive get the 3.0-liter V6 making 228 hp and 221 lb.ft. in the C300 4Matic, while the top-of-the-line rear-drive powertrain is the 3.5-liter V6 making 302 hp and 273 lb-ft, an increase of 34 ponies over 2011's C350.

All engines run through the company's seven-speed 7G-Tronic transmission. The combination of direct injection, an extra cog in the gearbox and a small overall weight savings help boost fuel economy by up to 15 percent. The gains are bigger in other markets, where an engine stop/start system is also standard. That feature will be coming to the U.S. when fuel economy pressures justify the additional complexity and cost of the system. Mercedes hasn't released final EPA figures, but offered preliminary combined numbers (by engine) of 24 mpg, 20 mpg, and 21 mpg, respectively.

Like overall efficiency, dynamic performance is also improved. Daimler says to expect a 5.9-second 0-60 mph dash for the 3.5-liter and 7.1 seconds for the other two powertrains.

As luck of the press-fleet draw would have it, our ride on the twisty roads of Tenerife (the largest of Spain's Canary Islands) was a rear-wheel-drive C350 equipped with the Elegance package. The Stateside equivalent would be called the Luxury model. Significant differences separate this model from the Sport: a four-spoke steering wheel, either rich brown ash or burr walnut and wide S-Class-style headrests with side bolsters (great for resting passengers).

While Sport C-Class models (known as Avantgarde editions in the EU) possess a sportier countenance with a CLS-style grill, AMG-style three-spoke steering wheel and gloss black ash, our C seemed to be the execution that most entry-level luxury buyers are looking for. There's something proper about looking out over the Three-Pointed Star standing proud over the chrome radiator surround. Ditto for the inside's rich wood appliqués and soft Nappa leather.

Our unit had the optional Audio 20 system with integrated navigation and a high-resolution (800x400 pixel) seven-inch screen. Like so many other vehicles, the C's new system is Internet-capable using Bluetooth tethered to a data-capable smartphone. Compared to the operation of the 2012 Audi A6 (with the optional fully-integrated, built-in data link), the new M-B system felt clunky. During a demonstration on the island, acquiring Web access and doing anything productive took too many clicks and rotations of the COMAND controller. Given Audi's introduction of a touchpad (A6, A7 and A8), this aspect of the revised C-Class seems behind the curve. Good thing this is another one of those non-U.S. features for now, so Mercedes has time to get it right before it makes the trek across the Atlantic.

Volcanic activity raised Tenerife out of the water off the Northwest coast of Africa. It's simultaneously a beautiful vacation spot for Europeans and an excellent place to drive a new Benz briskly.

The C350 drives solidly, in the manner of a small big car. There's no suspension chop or harshness. The new C has slightly revised suspension geometry and a brace of new bushings. The basic steel-spring setup (struts in front and an independent multi-link design in back) carries over. Dampers on all models automatically adjust between two ride settings and there are three available suspensions calibrations: Luxury, Sport and AMG. Our tester's softest suspension didn't offer any driver-controlled adjustability and its range isn't as broad as the higher-performance versions.

Our C350 also included a Sport/Comfort switch that modified the seven-speed's shift schedule. As you'd expect, the transmission moved up shift points and held gears longer. The hydraulic power rack-and-pinion steering also heavied up in Sport mode and delivered more feel, but don't expect the tactile sensations of a sports car.
 
 
Even in Sport mode, this is a sporty sedan, not a sport sedan – more of a baby S-Class, not an Infiniti G. Cornering is clean and predictable; there's no toss-and-set, just a smooth roll-and-stick. Pushed hard, however, and there's a little understeer. Push harder and M-B's electronic stability control works to prevent oversteer (expectedly) and understeer (unexpectedly). Yup, in some situations, the ESP actually induces additional yaw. The ESP makes the new C-Class feel totally locked down, yet it further robs the car of the playfulness you feel behind the wheel of a BMW 3 Series.

The V6 is quiet at light throttle, but wakes up with some pedal. It sounds good at lower revs where most C-Class driver will spend their time. On the far side of the tach, the engine's note isn't particularly sonorous. It's not raspy or thrashy, just not very nice.
 
Showing that no place on Earth is perfect, our drive was rudely interrupted by a jackknifed semi. An alternative route gave us some miles of easy cruising, and in this more typical driving environment, the C350 drove easily and quietly. There was little road noise, but we were surprised by some decidedly un-Mercedes-like wind noise around the A-pillars. Exceptionally strong crosswinds coming in off the Atlantic may have been to blame, and such breezes are tough to develop for. More time behind the wheel will reveal whether wind noise is properly managed.

After a few more hours behind the wheel, the C-Class continued to feel like a small S-Class. What does the C give up aside from room, stature, status and the feeling like you're gliding over the Earth? Drivers who haven't piloted a modern S-Class won't miss much. However, we noticed details such as the feel of the COMAND knob. The S's is larger and feels as if it's milled from billet aluminum. Additionally, the flagship has a tiny volume control next to the bigger puck, and the feel and utility are far superior. Details like this cost something and are not usually found in this price segment.
 
 
While the 2012 C-Class is already on sale in Europe, we'll get the new sedan, coupe, AMG sedan, and AMG coupe this Fall. (According to Mercedes-Benz, America's reluctance to accept station wagons means we won't be getting the C-Class Touring models. For shame.) Pricing hasn't been announced for the States, but given global competitiveness, expect Monroney labels to closely overlay the current C-Class range.

As fuel prices rise and forced fiscal conservatism continues to impact buying decisions, Mercedes executives couldn't have hoped for a better environment to launch the best Baby Benz ever, and for buyers unable to pony up for an S, the C-Class easily fits the entry-level luxury bill.

Mercedes to make next-gen C-Class an all-hybrid range

  

2012 Mercedes C-Class Coupe

Next-generation 2013 C-Class range will dramatically reduce its CO2 emissions ratings

By Alex Ricciuti

More than having a hybrid variant for each model in its range, Mercedes-Benz is going further than that on the next-generation C-Class expected in 2013.
(Last year we reported on plans Mercedes-Benz has for an all-hybrid S-Class lineup too.)

Now, according to a report by Autocar, Mercedes-Benz wants a hybrid version of each variant in the next-generation C-Class range expeced in 2013.

In an effort to dramatically reduce CO2 emission on the C-Class family, Mercedes-Benz will hybridize the entire range, including diesels, with the smallest output diesel engine aiming for an emissions quotient of just 100 g/km. For the most frugal petrol power plant, the automaker wants a C02 rating of no more than 120 g/km.

According to Autocar, Mercedes-Benz is already in the midst of testing early prototypes and is even considering developing a new three-cylinder for the C-Class range. As we know, BMW has confirmed it is developing a three-cylinder power plant for its compact models.

Mercedes-Benz is also considering cylinder deactivation tech for its four-cylinder units that would reduce the engine to operating on just 2-cylinders when less power is needed.

The premium automaker is also developing new engine, transmission and wheel bearings designs that reduce friction and improve fuel-economy.

Weight on the next C-Class will also be reduced by around 10 percent, according to the report.

2011 Mercedes-Benz SLS AMG: Suspension Walkaround

In the end, the $200,000 SLS AMG is like any other car in that I can jack it up, put jack stands underneath, yank the wheels off and have a good look at the mechanicals. The trick is getting my hands on the keys for a couple of days. As you can see above I managed to do just that.

This particular car came out of the west coast Mercedes-Benz press fleet and it's made the rounds. It has over 15,000 hard miles on the clock. More than a few celebrity posteriors have sat upon these red leather seats. One would assume it's been to the Grammys, the Golden Globe Awards and the Oscars, and we're pretty certain Adam Carolla flogged it during the taping of his yet-to-be-seen response to Top Gear, a show that will air on Speed if it airs at all.

So is there anything left? Let's have a look.
The forged aluminum upper control arm bolts to aluminum brackets which are in turn bolted to a cast aluminum section of the aluminum space frame. All told, the car's entire aluminum space frame weighs just 241 kg, otherwise known to us as 532 pounds.


And yes, 15,000 miles of hard driving and serious profiling have left it all a bit dusty.

 2011_SLSAMG_1600_sus_fr_det_brk_2.jpg 
The massive 15.4-inch rotors are of the two-piece variety, even though dozens of parts are necessary. Ten sets of spacers, clips and bolts allow the 1.4-inch thick ventilated, slotted and drilled cast-iron rotor to "float' on its aluminum hub.

  2011_SLSAMG_1600_sus_fr_det_brk_4.jpg 
Monstrous rotors demand humungous calipers, and the folks at AMG have obliged. These six piston (yellow x2) calipers feature an open pad window with a bridge bolt (white) that can be removed when it's time to change pads. The ears of the pads themselves feature tiny mass damper weights to quell vibration.

  2011_SLSAMG_1600_sus_fr_det_shock_tower.jpg 
The AMG's 563-horsepower 6.2-liter V8 (yes, I know it says 6.3 on the side of the car, but the displacement is actually 6.2 liters) ... what was I saying? Oh, yes -- the V8 engine sits so far back that the shock towers (green) tie into a frame crossmember that spans across the engine bay entirely in front of the pulleys and accessories on the front of the motor.

  2011_SLSAMG_1600_sus_rr_oa_3.jpg 
The rear suspension is also made up of double wishbones and coil-over aluminum-body shocks.

  2011_SLSAMG_1600_sus_rr_det_larm_fr.jpg 
 This forged aluminum lower wishbone truly is shaped like a wishbone. The lower end of the Sachs aluminum shock (yellow) necks down to clear the driveshaft.

 2011_SLSAMG_1600_sus_rr_oa_low_r34.jpg 
Double wishbones alone can't keep the rear wheels pointed straight ahead. In the front there's a steering rack, which is only straight when you want it to be.

Here in back you need a fixed toe-link (yellow) instead. The relative lengths of the upper arm, the lower wishbone and this link create a tiny measured amount of bump-steer, typically a wee bit of roll understeer to prevent the ass-end from swapping ends with the front.

Of course you can easily achieve that whenever you want by standing on the gas and boiling the rear tires with the stability control switched off. Or so I hear.

 2011_SLSAMG_1600_sus_rr_det_uarm_mount.jpg 
Like the front, the rear forged aluminum arms bolt to aluminum brackets that bolt to the aluminum space frame.

  2011_SLSAMG_1600_sus_rr_stabbar.jpg 
Like the front, steel is the material of choice for the stabilizer bar (yellow) and its drop link. Also the coil spring. Anything that sees a lot of torsional cycling is best made of spring steel.

  2011_SLSAMG_1600_sus_rr_det_brk_2.jpg 
Massive brakes adorn the rear of the SLS, but here the ventilated, slotted and drilled discs are one-piece cast-iron units. The brake calipers are 4-piston fixed units, but here the bridge (yellow) is fixed. You have to remove these calipers to change pads. Like the front, the ears of the rear pads have mass dampers connected to them.

  2011_SLSAMG_1600_sus_rr_det_tire.jpg 
It's no surprise that the wheel and tire package is huge. Continental ContiSport Contact 5P asymmetrical summer tires, sized 265/35ZR19, ride on 19-by-9.5-inch forged aluminum 10-spoke AMG wheels. The assemblies weigh 48.5 pounds, light for their size. And that's just the front.
In back you'll find 295/30ZR20 tires on 20-by-11-inch rims. These tip the scales at 57 pounds apiece. The forged wheels are not standard equipment, either. The option costs a mere $2,400, but who's counting in this price range?

Luxurious Merc 4x4 just keeps on rolling

REPUTATION is reaping rewards for the Mercedes-Benz ML series of luxury 4x4 models.

The big, no-nonsense vehicle has survived in times which have seen lesser rivals struggle. In fact, the ML presses on with strong demand from those who appreciate its virtues and can stand the running costs.

The range on sale in the UK today comprises eight versions, two petrol and six diesels in three levels of trim and are priced from a little over pounds 42,200 to almost pounds 59,000.

I tried the latest 231bhp 3.0 V6 with BlueEfficiency diesel engine and in the high-specification Grand Edition trim.

In common with the rest of the range this comes with a seven-speed automatic gearbox with paddle-shift selection available, permanent fourwheel-drive incorporating electronic traction control and hill descent, multi-media info-tainment system and this Grand Edition was fitted with optional air suspension at pounds 1,360, memory package for seats and also a surround sound and entertainment system for the rear seats which added a further pounds 3,100 to the price.

It is not cheap with a total price of pounds 57,855 for this model, but it is extremely comfortable, very well built, very capable both on and off road and it scores very highly in occupant safety.


You sit high and commanding in the ML 350 with good sight-lines all round and you have a reversing camera and sensors to help with parking and turning, very big and effective wipers and bright far reaching headlights.

Performance is respectable and it feels responsive and eager from rest and overtaking. It also steers with confidence and slows very quickly and with utter control and no drama.

With the air suspension it automatically adjusts to load and driving characteristics and it takes road shocks in its stride, although you can hear the wheels riding up or down without upsetting the occupants.

I averaged almost 30mpg, a little way below the official combined consumption, but that is remarkable for a vehicle weighing almost 2.2 tonnes, and shows how effective the latest diesel is when it comes to stretching the gallon.

Facts and figures Mercedes-Benz ML350 CDI BlueEfficiency Grand Edition Price: pounds 57,855 Mechanical: 231ps, 2,998cc, 6cyl diesel engine driving four wheels via seven-speed automatic gearbox Max speed: 137mph 0-62mph: 7.6 seconds Combined mpg: 30 Insurance group: 18 CO emissions: 240g/km BIK rating: 35% Warranty: 3yrs/unlimited mileage



CAPTION(S):

STRONG DEMAND - The Mercedes ML is a big beast in all respects, with excellent roadholding

The S400 Hybrid and BlueTEC vehicles have also made the rounds for various marquee events during the 2011 award season as the transportation of choice among a select group of celebrities -- in addition to Oscar Winner Natalie Portman -- including Oscar Winner Colin Firth, Amy Adams, Mark Wahlberg, Carey Mulligan, James Franco, Helen Mirren, Aaron Eckhart, Oliver Stone, Jesse Eisenberg, Ben Affleck, Robert Duvall, Eva Mendes, Jake Gyllenhaal, Kirsten Dunst, Julia Stiles, Matthew Rhys, Ali Larter and Hayden Panettiere among others. Since its debut, the Mercedes-Benz S400 HYBRID luxury sedan has been the vehicle of choice for many eco-conscious A-list actors including Tobey Maguire, Gerard Butler and Demi Moore among others.

Mercedes-Benz kicked off award season as a title sponsor of the Palm Springs International Film Festival and The Art of Elysium's Fourth Annual Black Tie charity gala. In addition, the Company sponsored the Hollywood Dominos 4th Annual Gala benefiting The Seven Bar Foundation, and their annual Academy Awards viewing party at the Soho House West Hollywood.

The S400 HYBRID luxury sedan and Zero Emission B-Class Hydrogen Fuel Cell vehicle were the vehicles of choice for Oscar Winner Natalie Portman throughout the 2011 award season while attending marquee events such as the Golden Globe Awards, Palm Springs International Film Festival, Screen Actors Guild Awards, Independent Spirit Awards and the Academy Awards.

"It's good that there are now vehicles with alternative fuel options, from clean diesel, hybrid and even hydrogen, that are becoming more widely available," said Portman.

Only available in California currently due to the lack of fueling stations nationally, the Mercedes-Benz Zero Emission B-Class Hydrogen Electric Fuel Cell vehicle offers celebrities, tastemakers and the truly eco conscious consumers a greater selection in choosing to go green. With only 70 to be leased in California, the new Mercedes-Benz F-Cell is essentially an electric car that is fueled by compressed hydrogen that boasts an equivalent fuel mileage of 86.6 city-highway miles per gallon with a range of up to 240 miles, can be re-fueled in a few as 3 minutes, and produces water as the only emission.

Harman Unveils Docking Navigation System with Mercedes-Benz

Harman, a global audio and infotainment group, unveilied a navigation solution for Mercedes-Benz that blends the flexibility of portable navigation devices with the convenience of complete driver cockpit integration.

The new Becker Map Pilot continues a relationship between the Company's Becker brand and Daimler AG that dates back more than 60 years.

The Company said the new Becker Map Pilot navigation system, premiering in the new Mercedes-Benz SLK and in the new generation of C-Class, gives drivers a feature-rich and upgradeable navigation solution without compromising the convenience of an in-dash OEM solution. Data for the system is contained in a compact, tethered navigation "brain," which can be removed from its docking cradle to update map data or upload the latest applications and feature sets. The unit seamlessly connects to the vehicle's onboard radio and fixed-screen electronics via a tailor-made cradle conveniently and discreetly housed in the car's glove compartment.

"The Becker Map Pilot underscores the leading-edge innovation that has resulted from our long association with Daimler AG," said Michael Mauser, Co-President of Harman Automotive. "The system blends the flexibility of the latest generation of portable navigation devices with the convenience of in-dash display and accessible controls to produce a system that is both easy to use and easily upgraded in the field."

According to a release, the Becker Map Pilot is operated by means of conveniently-placed controls positioned on the car's multifunctional steering wheel, the turn/push control, and integrated voice commands. This approach provides maximum functionality while preventing driver distraction. The navigation route is shown on the large-format central display and instrument cluster, and voice instructions are reproduced in the best possible sound quality from the car's onboard speakers - a distinct advantage over conventional portable navigation systems.

The Company noted that the connectivity of the Becker Map Pilot ensures perfect integration and networking with the car's onboard electronics. The navigation unit can be removed from the vehicle in a single movement and can be updated online anytime using the Becker Map Pilot Webshop site which enables maps and software to be upgraded and personalized information such as points of interest (POIs) to be downloaded simply and conveniently. Harman intends to continuously expand the range of new applications available in the Webshop, adapting to the increasing expectations and personal needs of the user.

For maximum security, the Becker Map Pilot is not visible from outside the car and feels like a built-in navigation system when in use. A lock on the integrated cradle prevents the device from being removed without permission, and its location inside the glove compartment ensures the unit remains securely anchored. The direct link to the Mercedes-Benz SLK or C-Class base radio means that the latest traffic warnings and other updates can be incorporated automatically in the route planning system by means of the Traffic Message Channel (TMC), and the guidance system automatically adapts itself to the current traffic situation.

Harman designs, manufactures and markets a range of audio and infotainment solutions for the automotive, consumer and professional markets - supported by 15 brands including AKG, Becker, Harman Kardon, Infinity, JBL, Lexicon and Mark Levinson.
