2016 Mercedes-Benz C450 AMG Sport bridges the gap between C300 and C63

Mercedes-Benz is looking to its new C-Class for the second member of its new AMG Sport line, unveiling the C450 AMG 4Matic at today's 2015 Detroit Auto Show. Like the GLE450 AMG Coupe that debuted in early December, this particular C-Class bridges the gap between the standard C300 and the new Mercedes-AMG C63. Considering this, the C450 builds on the standard C400's 3.0-liter, twin-turbocharged V6, rather than getting a bespoke, high-performance engine. Output is up from 329 horsepower to 362 ponies, while torque is turned up from 354 pound-feet to 384 lb-ft. The result of these upgrades is a zippy 0-60-mile-per-hour sprint of 4.9 seconds and an electronically limited top speed of 155 mph. Those figures are identical to the Audi S4, while the BMW 335i xDrive is just a smidge quicker to 60, getting there in 4.8 seconds (the Bimmer is, however, limited to just 130 mph). Shuffling the 3.0-liter's grunt to a 4Matic all-wheel-drive system is the responsibility of Mercedes 7G-Tronic automatic gearbox that, despite not being a member of AMG's Speedshift dual-clutch family, still has its own mind for performance. Along with a quick-shifting, automatic Sport Plus mode, the C450 has a full manual shifting mode that, notably, will not automatically upshift, even when the engine is bouncing off the rev limiter. The C450 AMG hasn't only had its straight-line abilities boosted. Mercedes saw fit to include an AMG adaptive sport suspension with three-stage adjustable dampers, which have been pilfered from the C63 AMG. Paired with the aforementioned all-wheel-drive system, which can send up to two-thirds of its power to the rear axle, it's a fair to say this particular sedan should be one of the brand's more agile and entertaining. Beyond the mechanical bits, Mercedes has beefed up the exterior and interior aesthetics for its second AMG Sport model. The exterior has been touched up with new, staggered 18-inch, five-spoke wheels (or optional 19s), a more aggressive front fascia, a new rear bumper with a matte iridium diffuser, distinctive AMG badges and plenty of chrome and gloss-black elements. The cabin, meanwhile, is home to black MB Tex upholstery with red contrast stitching on the dash and doors, while AMG-specific upholstery lines the sport seats. The flat-bottomed, three-spokes steering wheel, meanwhile, is finished in Nappa leather. We'll have more on the 2016 C450 AMG Sport, including live images, coming soon from the floor of the 2015 Detroit Auto Show.

Mercedes GLE63 AMG Coupe teased

The very concept of the luxury crossover coupe often gets flamed for being not only ugly, but also impractical. However, after years of letting BMW blaze the trail with the X6, Mercedes-Benz recently entered the field with the GLE-Class Coupe. Now, it's time to add a little more pepper to the package with the newly teased GLE63 AMG Coupe. The video above gives a solid look at the three-quarters perspective of this high-performance high-rider. Compared to the standard version buyers get a different front bumper with larger air intakes and an arching wing that almost appears to be floating in space. Flashes in the clip show off AMG branding for the brake calipers, steering wheel and seats, as is expected. This is clearly not a vehicle that'll appeal to everyone, but it offers an alternative to the latest BMW X6 M with 567 horsepower and 553 pound-feet of torque. Mercedes isn't saying what lies under the hood of the GLE63 AMG Coupe yet. Although given the name, we suspect a version of the brand's 4.0-liter twin-turbocharged V8 is the likely choice. It's offered in the latest C63 AMG with either 469 or 503 hp. The debut for this CUV coupe is possible at the upcoming Detroit Auto Show, where the standard GLE Coupe will be unveiled.
