Some new artist rendering have surfaced showing what BMW's upcoming 2011 6-Series may look like.
While they're just one artist's interpretation, recent spy photos have shown the new 6-Series will feature aggressive styling that adopts several design cues from the Z4 roadster, 7-Series, and the CS concept.
Engine options will likely carry over from the current 6-Series, but the 360 hp 4.8-liter V8 will be replaced by the new 400 hp twin-turbo 4.4-liter V8 from the new 7-Series. The M6 is also expected to drop its V10 engine with 500 hp and 383 lb-ft of torque for a slightly retuned version of the X5 M and X6 M's new 4.4-liter twin-turbo V8 engine with 555 horsepower and 500 lb-ft of torque.
