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.

2015 Chinese Grand Prix shines bright sun on the dark days of racing

Yes, we tuned into the Formula One Grand Prix in Shanghai China to see a race. But we all know we really tuned in to see if Ferrari, or any other team, could make it a competitive race with Mercedes-AMG Petronas. Based on qualifying, things didn't get off the best of starts: Lewis Hamilton made it four-out-of-four at the front, leading all three Free Practice sessions and then taking pole position in his Mercedes. Nico Rosberg is making the most of his time in the simulator, getting closer to Hamilton as the months go by. This time he lined up in second, just 0.042 in arrears. Ferrari did its best to temper expectations after Malaysia. Even though Sebastian Vettel qualified in third, almost a second behind Hamilton, the Scuderia's race pace is still considered a danger. Kimi Raikkonen's final hot lap went sour in Turn 3 and dropped the Finn to sixth place on the grid. In between the Ferraris, Williams is another team desperately working to maintain its advantage, and both of its drivers capitalized on Raikkonen's misfortune. Felipe Massa took fourth, Valtteri Bottas was in fifth. Daniel Ricciardo led the Infiniti Red Bull Racing charge in seventh, ahead of Romain Grosjean in the Lotus earning a spirits-lifting eighth. The two Saubers continue to show how good the Ferrari engine is, with Felipe Nasr taking ninth position and teammate Marcus Ericsson in tenth. Yet when the lights went out, so did the racing, for the most part. At the end of the first lap, because of some excellent moves by Raikkonen on both Williams' and a terrible start by Ricciardo that dropped him to seventeenth, the order was Hamilton, Rosberg, Vettel, Raikkonen, Massa, Bottas, Grosjean, Nasr, Ericsson, and Pastor Maldonado in the Lotus rounding out the top ten. At the end of the race, the only positions that had changed were the final two: Ricciardo had a laps-long battle with Ericsson, passing, getting repassed, then passing again to take ninth for good, with Ericsson finishing tenth. Maldonado suffered the worst in a battle with Jenson Button in the McLaren, when Button misjudged the entry into Turn 1 for a pass and clouted the back of the Lotus. Button was able to finish but Maldonado had to retire. Yes, there were some decent moments in between, like Bottas getting by Massa at the start, then Raikkonen getting past Massa in the first few corners and the Finn's move on Bottas also letting Massa through.

Mercedes-Benz Concept GLC Coupe comes to China ready to fight BMW's X4

There's little denying that small crossovers are hot right now. Not only are automakers scrambling to exploit the popularity of the market, they're doing so by offering unique twists on the traditional two-box body style – enter the coupe-like four-door CUV. BMW, for example, has the X4, and now, Mercedes-Benz is bringing a challenger of its own. While it wears the concept name, the new GLC Coupe clearly foreshadows a production model that'll duke it out with the aforementioned BMW. If the vehicle shown above is any indication, when that fight happens, Mercedes will enter it with design on its side. The sheetmetal is muscular, with strong lines on the profile and the hood, while major themes in the front, back and sides are reminiscent of higher-end Silver Arrows. While we doubt the production GLC Coupe will be much of a trail bomber, fore and aft scuff plating is there to give the impression it can handle itself off road. Also, we feel obligated to give Mercedes bonus design points for the diagonally stacked quad exhausts at the back. It's worth noting that the Concept GLC Coupe's styling previews not one but two production vehicles, as it's logical to assume the design language featured here will have a strong influence on the next GLC (the crossover formerly known as the GLK). Not only will the GLC Coupe have aesthetics on its side, at 15.5-feet long and riding on a 111.4-inch wheelbase, it's larger than its rival from Munich, too, although only just. The X4 is two inches shorter overall and has an extra 0.8 inches between the axles. The Benz is wider, too, at 78.7 inches, compared to 74.1. Lending credence to the Concept GLC Coupe's production status, Mercedes released a pretty substantial array of technical details on its new four-door, coupe-crossover. With a twin-turbocharged, 3.0-liter V6 punching out 367 horsepower and 387 pound-feet of torque, we're betting this would be the AMG Sport variant, rather than your everyday GLC. 4Matic all-wheel drive is a must-have in this segment, and it's present here, while a nine-speed automatic transmission is responsible for distributing power. The Concept GLC Coupe will be shown this week at the 2015 Shanghai Motor Show. Check back then for more. Mercedes-Benz Concept GLC Coupe The next coup Stuttgart / Shanghai. In a flowing transition, Mercedes-Benz lands the next coup: the Concept GLC Coupe is a near-production-standard study that carries the successful GLE Coupe formula over into a more compact segment.
