Now that there's less reason for secrecy since we've already seen the standard versions of the new F10 5-Series on the road, BMW has started peeling off the psychedelic camouflage from its 2011 M5 prototypes.
Key stylistic highlights of the new M5's look will include the four tailpipes, chunkier front and rear bumper designs, unique exterior mirrors and alloy wheels while there's also talk about a carbon fiber roof and bootlid which should also help reduce weight.
As we've already told you in earlier posts, BMW's new uper saloon will be the first M5 to adopt turbocharging with power coming from a reworked version of the X5 M and X6 M's 4.4-liter bi-turbo V8 that replaces the current model's V10 unit.
