A prototype Mercedes McLaren SLR has been spotted on a mountain road in Spain. The SLR is presumed to be upgraded later this year. The updates are said to include a power increase for its supercharged V8 from 626 to 650 hp, an updated interior, 19-inch wheels, a firmer suspension, a new braking system and increased weight savings. New colors (blue exterior, tan interior) may also be available.

Maybe they will use an AMG engine?
They should make a convertible version, that would be really cool. I don’t know how they would do the doors then.

There are going to be four new mclaren slr’s, a convertable, and 3 sp’s (sports pack) which are lower, stiffer, harder suspension, more bhp and larger wheels but this isnt one of them
