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.

Next Mercedes-Benz C-Class to get diesel, hybrid versions

Mercedes-Benz is planning a more aggressive product strategy for its next-generation C-Class range. "We were fighting the 3 Series with two arms tied behind our back, and now we will change that," Steve Cannon, the automaker's US CEO, told Automotive News in a recent interview.
In addition to offering more body styles of the new C-Class, AN reports that the revamped Mercedes will also be offered here with hybrid and diesel powertrains. Currently, the C-Class comes in coupe and sedan variants, with only gasoline engines. The BMW 3 Series, however, is available as a sedan, coupe, convertible and wagon, and offers buyers the choice of gasoline, diesel (the upcoming 328d) or hybrid power.
Mercedes-Benz will show the next-generation C-Class at the 2014 Detroit Auto Show, with sales of the US-built sedan following in August. Coupe, convertible and hybrid models will follow in early 2015, and while diesel and all-wheel-drive versions are planned, no specific timetable has been released regarding availability.

Brabus-tuned Mercedes G500 4x4 is an over-powered off-roader

Even from the factory, the Mercedes-Benz G500 4x42 is an off-road bruiser that's good for 415 horsepower and 450 pound-feet of torque. Apparently, those already meaty figures just aren't enough for the power-hungry folks at Brabus. The company's new tuning kit for the twin-turbo 4.0-liter V8 pushes things up to 493 hp and a prodigious 523 lb-ft of twist. On top of the grunt, buyers can order a heap of extras to make the SUV look a whole lot meaner. They're all going on display at the 2015 Frankfurt Motor Show. The heart of Brabus' power upgrade is its custom control module to tweak the engine management, and the result is adjusted boost pressure and the mapping for the fuel injection and ignition. There's also a stainless steel exhaust with butterflies that vary between "Sport" and an appropriately named "Coming Home" mode at the press of a button. The chrome tailpipes add an extra visual pop, too. The G500 4x42 rides on off-road tires, and even after Brabus' big boost, it's not lightning quick. The run to 62 miles per hour now takes 6.9 seconds, and the rubber also mandates a top speed limited to 130 mph. For buyers really looking to show off, Brabus has a wild body kit for the G500, too. It includes new lower bumpers and polished underbody guards. Meanwhile, the hood grows a scoop, and the headlight update adds black-tinted Xenon lights with LED turn signals to replace the units usually on the fenders. Inside, a mix of quilted leather, Alcantara and bright red stitches finishes off the brash tweaks. World premiere at the IAA 2015 BRABUS refines the Mercedes G 500 4x42 368 kW / 500 HP, 710 Nm of torque and exclusive BRABUS luxury appointments for the extreme off-roader Mercedes G 500 4x42: the new special model of the G-Class is designed for maximum off-road capabilities and offers the perfect basis for exclusive refinement a la BRABUS (Brabus-Allee, D-46240 Bottrop, phone +49 / (0) 2041 / 777-0, fax +49 / (0) 2041 / 777 111, Internet www.brabus.com). This includes an increase in the power output of the twin-turbo V8 to 368 kW / 500 HP (493 bhp) and a boost in its peak torque to 710 Nm (523 lb-ft). As a result, the tuned off-roader sprints from rest to 100 km/h (62 mph) in just 6.9 seconds. Due to the all-out off-road tires, the top speed is limited electronically to 210 km/h (130 mph). The spectacular appearance of the all-wheel-drive car is bolstered further by a high-end BRABUS paint finish and targeted BRABUS bodywork modifications.
