Mercedes-AMG C63 Coupe gets first video teaser

With less than a week until its big reveal, Mercedes-AMG has kicked up its teasing of the two-door version of the C63 Sedan. This 16-second teaser shows off the sonorous sounds of the coupe's expected powerplant, a 4.0-liter, twin-turbocharged V8. The car is still camouflaged, although we're able to get a nice look at the two-door C-Class' form, which we must say is darn attractive. As previously reported, the C63 Coupe will almost certainly mirror its four-door counterpart in terms of mechanicals. So that 4.0-liter V8 should be offered in both 469- and 503-horsepower varieties, with grunt dispatched to the rear wheels via a seven-speed AMG Speedshift transmission. While output should be identical, it's a safe bet that the two-door C63 will trim some of the four-door's 3,900-plus-pound curb weight. That should, hopefully, improve upon the C63 S' already impressive 3.9-second sprint to 60. We'll have much, much more on the Mercedes-AMG C63 Coupe when it makes its grand debut on August 19. Until then, check out the video of the prototype being flung around the track and stay tuned for the official reveal of the non-AMG C-Class Coupe, slated for later today.

On Location in Switzerland and France in the 2016 Mercedes GLC

Our first test drive of the 2016 Mercedes-Benz GLC was a flat-out European adventure. We spent two days driving through Switzerland and France, with a brief stop in Germany. The twisty roads took us through vineyards, farmland, and villages that are centuries old. The historic setting stood in contrast with the sleek, contemporary GLC. It's Mercedes' newest small crossover and replaces the GLK in the company's portfolio. While we soaked in the culture, we also got a taste of the GLC's abilities. This is not a simple refresh of the GLK. The GLC has delicate curves, a turbocharged four-cylinder engine, and a new wave of Mercedes technology. The changes are sweeping, and the GLC looks and drives much differently than the edgy, V6-powered GLK. Admittedly, we liked the GLK's rough-hewn feel, though we warmed to the GLC's more subtle charm. This evolution may have occurred as we crossed the Alsatian region of France. Or maybe in Amsterdam, where we contemplated the GLC's merits and our travel plans for getting back across the Atlantic. Regardless, over the course of our trip we reached a conclusion: the GLC is more in-step with what today's consumers want in their crossovers. It took a long drive over some of Europe's oldest roads for us to arrive at Mercedes' new way of thinking. Related Video:

Mercedes-AMG to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.
