From BMW Press Release:
Like all current high-performance-automobiles from the BMW M GmbH, the new BMW M3 Saloon and new BMW M4 Coupé are offered in two performance levels: Besides a 480 hp variant with a 6-speed manual shift, there is also the choice of a Competition model with 510 hp and an 8-speed M Steptronic transmission with Drivelogic.
“For customers who prefer a puristic performance experience and particularly intense interaction with their vehicle, the model variants with a manual transmission constitute an offer that is unique in this segment,” explains Dirk Häcker, head of Development M Automobiles and BMW Individual. “On the other hand, with the Competition versions of the new BMW M3 Saloon and new BMW M4 Coupé, we are addressing maximum dynamics in regards power development and transfer – initially with classic rear-wheel drive and, at a later date, also in conjunction with the latest version of our four-wheel drive system M xDrive.”
Compared with the predecessor models, the straight six-cylinder engines featured by the new high-performance sports cars deliver a maximum output increase of 49 hp and 60 hp (Competition models) and a maximum torque of up to 650 Nm [479 lb-ft].
