2015 Mercedes-AMG C63 S Review

"It's about great cars on great roads." The late David E. Davis, Jr., said this of Winding Road when he took the reins as editor-in-chief in 2006. Our mission at that magazine was to not just review cars, but to describe the emotional experience of piloting brilliant machines down beautiful roads. "The art of driving," per David E. This all comes flooding back into my mind as I pull out of a Shell station onto Angeles Crest Highway, just south of the 210 freeway in La Canada Flintridge, CA. I'm in the 2015 Mercedes-AMG C63 S. I've got a full tank of fuel, the whole day to myself, and I'm staring down one of the finest driving roads in the country. Prior to this moment, I spent two days bombing around the greater Los Angeles area in this sinister-looking C63 S. This car is a villain, and looks appropriately so in black paint with the $750 AMG Exterior Night Styling pack. The C-Class as a whole is far more upscale in this latest generation, with its long hood, cab-rearward design, and short rear deck. "Baby S-Class" is not an exaggeration. Thankfully, the addition of AMG bits don't detract from the new C's more premium aura. Where a BMW M3 just looks like a brash 3 Series, the C63 is more like a C400 with a trick up its sleeve. The 4.0-liter V8 is an exceptional engine. Start the engine, and there's no question you're blessed with the power of AMG. Any worries I had about the new, twin-turbocharged, 4.0-liter V8 not providing enough aural delight are gone, especially with the $1,250 AMG Performance Exhaust. At start-up there's a low, burbly sound quality, typical of a V8. At full throttle, it's loud, angry, and passionate. I will always miss the naturally aspirated, 6.2-liter M156 V8 from the last C63, not only for its noise, but for its character. That said, I eagerly welcome Mercedes' new turbocharged techniques. The 4.0-liter V8 is an exceptional engine. In C63 S guise, the M178 lump makes 503 horsepower and 516 pound-feet of torque, the latter of which comes on in full force as low as 1,750 rpm. That's a ton of power for the 3,935-pound C63. But it never feels like there's too much to handle. Power comes on progressively, and when I mash the throttle on a straight stretch of pavement, the car is composed and controlled. And quick. Seriously quick. Zero-to-sixty-in-under-four-seconds quick. The balance between viciousness and grace is perfectly met in this new C63.

2015 Mercedes-Benz ML400 Quick Spin

Mercedes-Benz has taken a risk in its quest to downsize its engine range. For 2015, the brand's popular M-Class five-passenger CUV did away with its trusty 4.4-liter, twin-turbocharged V8, and has replaced it with a 3.0-liter, twin-turbocharged V6. It's no surprise that power is down thanks to this move. Outputs of 402 horsepower and 443 pound-feet of torque are replaced by 329 hp and 354 lb-ft, but weight is down significantly as well. The new ML400 is nearly 300 pounds lighter than the 4,982-pound ML550. Will that tradeoff be enough to satisfy a buying public that's embraced falling fuel prices by buying bigger and thirstier vehicles? To find out if the blown V6 is a suitable replacement for the twin-turbo V8, we spent a week at the helm of the all-new ML400. Driving Notes This 3.0-liter, twin-turbocharged V6 is the same engine being offered in the C400 and E400 sedans. Typical of today's turbocharged engines, peak torque is spread lavishly across the rev range, from 1,600 to 4,000 rpm. That's not as generous a spread as the ML550, which offers all its torque between 1,600 and 4,750, but the power on offer is easy to access. Importantly, the new V6 never feels flat-footed or unable to answer our commands. In fact, the ML400 feels even quicker than its six-second sprint to 60 would indicate, although it's not so fast as to challenge the 5.3-second time of the ML550. After a slight and expected bout of turbo lag, the power arrives suddenly and proceeds linearly until just south of the engine's 6,500-rpm redline. The throttle response is soft in Eco mode, as expected, but sharpens up slightly when the fuel-sipping mode is off, where the gas pedal is still easy to modulate. It's a quiet engine, too. Compared to the brawnier exhaust note of the old ML550 or the howling six-cylinder in the BMW X5 xDrive35i, the ML400's note is smooth and refined, befitting of a V6. Its turbocharged nature is instantly noticed, though. Get on the throttle and the 3.0-liter happily hisses its way up the tachometer. But, it's only when you get on the throttle hard that the engine really weighs in. In day-to-day driving and traffic its soundtrack is unobtrusive and relaxed. The EPA rates the ML400's fuel economy at 18-miles-per-gallon city and a 22-mpg on the highway. That's better than the 14 city and 19 highway of the old V8 ML, but it still seems a bit low, especially for the highway figure.

Formula 1 seeking independent engine supplier

Formula 1 could get a new engine supplier in the near future, if Bernie Ecclestone and the independent teams gets their way. According to Autosport, the FIA is soon to open the contract up for bids, and there are already several manufacturers that have expressed interest. Currently Mercedes, Ferrari, Renault, and Honda supply engines – both to their own premier teams (Red Bull and McLaren for the latter two) but also to other teams like Williams, Sauber, and Toro Rosso. Because the new turbocharged V6 hybrid power units cost those four suppliers so much to develop, they're charging their customer teams big bucks – around $20-30 million per season – to provide the engines. These costs are much higher than the $10 million or so it used to cost to purchase a V8 engine under the previous regulations. Ecclestone figures it's time to bring in another supplier who will not run their own team and not play favorites, but will supply engines to private teams at a lower cost. There are already a number of potential suppliers under consideration. One of them is said to be Cosworth, which has a long history in the series stretching back to 1963. The British firm stepped back between 2007 and 2009, returned in 2010, and dropped out again after 2013. The development could be of particular benefit to Red Bull, which has been unable to find an engine supplier and could be forced out of the series as a result. The team has long been powered by Renault, but that relationship has grown sour. And the other three engine manufacturers have not been forthcoming in offering an alternative arrangement for the team.
