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.

Mercedes working on new inline-six engines

Mercedes-Benz will make a return to the inline-six-cylinder engine game, according to a report from the UK's AutoCar. It's not clear what's prompting the phasing out of the current array of V6s.
We'll see the first inline-six from Mercedes in next-generation E-Class, set to debut in 2016. Following that, it'll arrive as part of a mid-cycle refresh for the C-Class in 2017. What's particularly special about the new inline-six is its modular nature, which will allow Mercedes to eventually spinoff three- and four-cylinder options, with the three-pot arriving alongside the new inline-six.
In other news, AutoCar uncovered some details on the next C-Class AMG, which will ditch its excellent 6.2-liter, AMG V8 in favor of a 4.0-liter, twin-turbocharged V8, although we've already told you about that. What we didn't know at the time, though, was that the 4.0-liter would be paired first with a new, seven-speed AMG Speedshift transmission and offer all-wheel drive. AC also reports that a nine-speed Speedshift is in the works.

Smart brand will be built in China as a Daimler-Geely joint

FRANKFURT/BEIJING — Daimler will build its next generation of Smart electric cars in China through a joint venture with Geely, as a way to increase economies of scale in a market segment that is struggling to turn a profit. China's Geely built a stake of almost 10 percent in Daimler last year, saying it wanted to forge an alliance to develop electric and self-driving cars to better compete against new challengers such as Uber and Google. Daimler said on Thursday it would build the next generation of Smart-branded city cars at a purpose-built factory in China, and planned to share its expertise in manufacturing, engineering and design with Geely. The high cost of electric car batteries has made it hard for automakers to build affordable zero-emissions vehicles, leading several of them to strike alliances with Chinese partners. Daimler's German rival BMW recently unveiled plans to build electric Minis in China, where production costs are low and demand for small electric cars is rising. Daimler and Geely did not disclose financial terms of their deal. The details of the joint venture will be finalized by the end of 2019, they said in a joint press release. Daimler currently develops and builds Smart cars with Renault at factories in France and Slovenia. The Daimler factory in Hambach, France, will be retooled to build Mercedes-Benz cars. Geely has been expanding rapidly through mergers and acquisitions since 2010, when it acquired Swedish carmaker Volvo from Ford. Last year, Daimler and Geely set up a ride-hailing joint venture in China. Daimler's Chief Executive Dieter Zetsche said last month the German carmaker was in talks to deepen its alliance with Geely after the Chinese's group's chairman Li Shufu bought a 9.69 percent stake in Daimler in 2018.
