According to industry sources Ferrari are readying a replacement, or more likely an evolutionary step in the 458 Italia lineage, and a V8 twin-turbo powerplant will be at the heart of the prancing horse. The V8 twin-turbo is said to be based upon the California T’s 3.9-litre V8 bi-turbocharged engine, that unit produces 552bhp and 755Nm at 7,500 rpm. The 458’s possible switch to turbo power is said to be in response to Chinese emissions laws which penalize large capacity engines over 4.0-litres in size with a good old fashioned and complicated tax system. Ferrari is aiming for benchmark power from the engine and reports suggest they are looking to dethrone the McLaren 650s in the power-stakes with a rumored 655bhp, or above, monster. Former Chairman of Ferrari, did say that Ferrari were no longer seeking to produce the most powerful car, rather that the company would concentrate on producing the most complete performance car possible with the most refined engine. That seems to have changed. The 458 Italia’s successor may well follow an evolutionary exterior design, it is not yet clear if the Italia will be replaced entirely, test 458 mules under camouflage have been spotted. It may well be the case that the 458 receives a sheet metal upgrade, that’s fancy looking body panels to you and I. The 458 Italia is expected to be unveiled at the 2015 Geneva Motorshow.
