[Updated 2:08 p.m. PST Dec. 9: The scientists plan to take this information and run with it — at least, run as fast as good judgment (and Curiosity's theoretical top speed of just 1.57 inches per second on flat ground) will allow. (latimes.com)
Top speed, like all M cars, will be limited to 155 mph, although the taller individual gearing and longer final drive ratio made possible by the significant increase in torque should see the new car's theoretical top speed rise to more than 180 mph. (autoweek.com)
This might suffice for GT3 or DTM cars, but it won't do for a machine that somehow has to harness 1341bhp and has a theoretical top speed of 273mph (limited by the wing itself). (evo.co.uk)
