Our spy photographers spotted the 2015 Mercedes-Benz C63 AMG testing in Sweden. The high-performance model will debut later this year as the top model for the new 2015 Mercedes-Benz C-Class that bowed in January at the Detroit auto show.
Despite camouflage tape, this 2015 Mercedes-Benz C63 AMG prototype clearly shows off its performance intentions. The nose betrays its air-inhaling mission by way of enlarged inlets at either end of the front fascia, the mismatched wheels cover enormous brake discs gripped by gold brake calipers (AMG's signal for carbon-ceramic stoppers), and four large exhaust tips peek out from beneath the rear bumper.
The 2015 Mercedes-Benz C63 AMG is expected to use a twin-turbocharged 4.0-liter V-8 engine, which could produce around 460 hp and is also tipped to be used in the new SLS AMG-replacing sports car known internally as the C190. AMG boss Tobias Moers confirmed to our colleagues at Motor Trend that the M156 6.2-liter V-8 engine used in the outgoing C63 AMG has been discontinued. He also suggested that we may see a replacement for that engine at the New York auto show -- it's not clear whether the engine itself will be shown, or if a different AMG will debut in the Big Apple.
The actual C63 AMG, however, is not expected to debut until later this year. Our spy photographer says the 2015 Mercedes-Benz C63 AMG will make an appearance at the Paris auto show, but we suspect it could be held over until the Los Angeles show in the fall. Southern California is one of the largest sales markets for AMG cars (Newport Beach, specifically), and thus the brand often shows its go-fast wares there; last year, the S65 AMG sedan bowed in L.A.
Speaking to Motor Trend in Geneva, AMG boss Moers also quashed speculation that Mercedes would follow the lead of the BMW M3/M4 in switching to turbocharged six-cylinder engines for high-performance cars. "What is our unique selling point? The V-8. Why would you want a [six-cylinder]?," he told MT.
After the C63 AMG sedan is revealed this year, European correspondent Georg Kacher reports that the Mercedes-Benz C-Class coupe will arrive in 2016. That, too, will spawn a C63 AMG variant, although it sounds like the two-door version will be about two years behind the sedan seen here.
