The roadster variant of the MP4-12C will sport a fully-retractable hard top made from carbon fiber and no other changes will be made. In more important news however, McLaren is focused on utilizing its potent 3.8-liter V8 with 593-hp in various McLaren models in the near future. Co-designed with Ricardo, a British automotive engineering firm, the V8 was designed to be used in “more than one car” according to Geoff Grose, head of vehicle development at McLaren. This all makes sense since we already knew that the F1 successor would be utilizing the powerplant from the MP4-12C.
But don’t expect it to push out the same 593-hp seen in the MP4-12C model. The engineering team at McLaren should have no difficulty in pushing more performance out of its V8 especially since the 3.8-liter was developed to be flexible with longevity in mind.
It’s still unknown when the F1 successor will make its official debut, but speculation has it pegged for 2013 even though McLaren would like a concept version out before the end of this year.
