The high-end “M brothers” were spotted yesterday by Motor Trend in the sunny state of California. The next generation 2013 BMW M6 was spied next to the new F10 M5 in a parking lot. Furthermore, the ad-hoc spy photographer says the M6′s exhaust note sound “mean and nasty as hell.”
“The 6 Series drop-top sounded just as mean and nasty as hell, and very healthy,” said Jon Welsh for Motor Trend. “And this was during nothing more than very light acceleration while navigating the parking lot!”
While BMW has yet to reveal the power unit under the hood, we believe the engine found in the new M5 will serve as a starting point for the new M6. The 4.4 liter V8 turbocharged engine is rumored to produce around 580 horsepower.
Due out in 2012, the new M6 will be available in both Coupe and Convertible variants. The redesigned M6 will have its own attributes and characteristics in order to challenge the established rivals from Porsche, Audi, Bentley, Aston Martin, Jaguar and Mercedes-Benz.
As seen in these new spy photos, the M6 continues to carry the typical wider rear fenders and the usual four-tailpipe exhaust system characteristic to M models. At the front end, a more aggressive and typical M-style bumper with integrated diffuser is included as well.
Surprisingly, the 2012 BMW M5 test mule continues to sport a light camouflage despite its official unveiling last month at Nurburgring.
The F10 M5 goes on sale in Spring 2012 featuring for the first time a turbocharged engine. The high-revving 4.4-liter (4395cc) turbocharged uses the BMW M TwinPower Turbo technology, twin-scroll turbochargers, high-precision direct fuel injection, VALVETRONIC variable valve control and a cross-bank exhaust manifold. The engine outputs 560 horsepower from 5,750-7,000 rpm and 680Nm (502 lb-ft) of torque from only 1500rpm.
The base price of the M5 will include important performance features such as the M double-clutch transmission, adaptive suspension, active M differential and compound brake system with the blue brake calipers. Other features include automatic climate control, Head-up Display, fine-grain Merino leather and sport seats.
