Mercedes updates G-Class including new 4.0-liter twin-turbo V8 [UPDATE]

UPDATE: Information on US availability (including corrected output figures) added to the revised text below. Mercedes has been building (or having Magna Steyr build) the G-Class for an unfathomable 36 years now. Needless to say, the legendary off-roader wouldn't still be around if not for the occasional update here and there, and that's just what the German automaker announced today. The list of enhancements to the iconic Gelandewagen is almost as long as its lifespan, but the most salient point here is the introduction of a new engine. The revised G550 introduces a new 4.0-liter twin-turbo V8, based on the high-performance engine in the Mercedes-AMG GT and C63, but retuned: in this application, it produces 416 horsepower and 450 pound-feet of torque (compared to 453 hp and 440 lb-ft in the GT or 503 and 480 in the GT S). We'd expect that engine to gradually make its way into other models as well. Though the G500 is the only one with a completely new unit, the other engines in the lineup have also been updated. The G350d bumps from 211 hp and 398 lb-ft to 245 hp and 442 lb-ft, the AMG G63 jumps from 536 hp to 563 (torque remains constant at 560 lb-ft), and the top-of-the-line, twelve-cylinder G65 (which we'll be getting Stateside for the first time) now produces 621 hp and a massive 738 lb-ft. Those figures result in a 0-62 time of 8.9 seconds for the diesel, 5.9 for the G500, 5.4 for the G63 and 5.3 for the G65 – which are altogether might impressive for a vehicle as big and boxy as the G-Wagen. All but the G65 now feature stop/start systems to help reduce fuel consumption too. Benz also revised the suspension tuning (while offering optional active dampers) and reprogrammed the ESP, ASR and ABS systems. Inside there's a new instrument cluster, the non-AMG models get new bumpers and flared wheel arches, and there's a bright new array of colors available for the AMG models, which can also be ordered in a new special Edition 463 featuring unique trim inside and out. The revised models will be arriving at US dealers in November, however the diesel model will not be making the transatlantic journey to our shores. The data in the press release below (as well as the images in the gallery above) pertain to the European models, with the correct output figures for the US models amended in the text above.

Mercedes may not be done with R-Class after all

The idea of blending a three-row SUV and a minivan into a luxury model like the Mercedes-Benz R-Class still seems wonderfully absurd, particularly when you consider that there was an AMG version of that German people-mover. Apparently, though, one of the brand's execs doesn't believe the concept behind the R-Class is all that bizarre. In fact, he thinks it could be time to try again. Wolf-Dieter Kurz, Mercedes' vice president in charge of SUVs and sports cars, believes that crossovers could be a major driver of product variants in the future due to their popularity. There are a lot of design possibilities to explore in the segment, in his opinion. "There was already one that we had in the portfolio – maybe we were too early – which was the R-Class, which we are still selling in China. It's doing good, with 12,000 to 14,000 units per year," Kurz said during the launch of the GLE and GLE Coupe, according to CarAdvice. Under a recent deal, the quirky model is made by AM General and exported out of the US. Kurz even suggested the exact niche that the new model might fill. "So let's say these more, let's say, on-road based but still very roomy, but not station wagon, is definitely an interesting segment also in the future," he said, according to CarAdvice. That almost sounds like a blend of wagon and SUV in a move not too dissimilar from the current Subaru Outback or the old R-Class. One hurdle for any future model reviving the concept of the R-Class is that the company is already bursting with CUVs. Every size is practically already filled with the GLA, GLC, GLE, and forthcoming GLS, plus Coupe variants for some of them.

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.
