Last month, BMW confirmed that the new 2014 BMW M3 and M4 models will be powered by an inline-six engine. The F80 M3 will debut, in concept form, at the 2013 Geneva Motor Show, and it might have a surprise under the hood.
According to sources close to our sister-magazine BimmerToday, the powerplant found under the hood is a newly developed 3.2 liter unit, still inline-six, which has its fundamentals in the current M3 engine, the S65 V8.
The engine is rated at 450 hp and with a new performance package it could reach 480 horsepower and a top speed of 300 km/h.
The M3 engine saga has been quite interesting so far, with initial reports mentioning a V6 powerplant as the choice for the super popular M product. BimmerToday’s sources say that V6 engine prototypes were indeed built and tested under the codename “Apollo”.
The 2014 BMW M3, production version, will debut in September 2013 at the Frankfurt Auto Show.
