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.

2013 Mercedes-Benz GLK250 Bluetec gets 33 mpg, priced from $38,950*

It's been more than a year since we first saw the 2013 Mercedes-Benz GLK250 Bluetec unveiled at the 2012 New York Auto Show, but it looks like the compact diesel crossover is finally starting to roll into dealerships. Those wanting to buy a diesel GLK will only have to pony up an extra $1,500 over a base, gas-powered GLK350, as the GLK250's starting price is listed at $38,590 (*not including $905 destination charge).
The turbocharged 2.1-liter four-cylinder diesel produces 200 horsepower and 369 pound-feet of torque, and Mercedes-Benz has also provided some fuel economy numbers for this model, with claimed EPA estimates of 24 miles per gallon city and 33 mpg highway. There is no listing for the GLK250 on the EPA's website yet, but the figures represent significant increase over the GLK350's lackluster 19 mpg city and 25 mpg highway figures, which are for the rear-wheel drive model. The GLK250 comes standard with the 4Matic all-wheel-drive system - a $2,000 option on GLK350 - meaning that if you want an all-wheel-drive version of the 2013 GLK, it's actually cheaper to opt for the diesel model. Head over to the Mercedes-Benz site for the full 2013 GLK-Class configurator.

2017 Mercedes-AMG C63 Coupe looks quick, mean

The latest Mercedes-Benz C-Class Coupe isn't even on the road yet. Still, the folks at AMG are already working at tweaking the two-door into a future high-performance variant as the natural challenger for the BMW M4. While this model is heavily camouflaged all the way around, an aggressive face akin to the C63 sedan is already pretty easy to spot. Both cars feature air dams with big openings to feed cool air to the 4.0-liter, twin-turbo V8 under the hood. Compared to the previously spied, standard version of the two-door C-Class, the AMG looks to feature wider front fenders, too. Despite the concealment, other visible high-performance touches include lower side sills and larger brakes peeking out behind the wheels. Of course, the four exhaust pipes sticking out the back are a big giveaway of the coupe's intended high-speed purpose, too. Like the C63 sedan, expect a choice of tunes of the V8 to be available with either 469 horsepower or the more powerful S with 503 hp. The wait to see the two-door without all of this camo shouldn't be too long, either. An earlier report suggests that both the standard coupe and AMG versions could debut at the upcoming Frankfurt Motor Show in September. Related Video:
