THIS was a surer thing than the All Blacks at Eden Park. BMW has announced a gruntier, grippier M3 by injecting the M4 CSís tuning package into the four-door sedan.
Mechanically the sedan steals the high-output 3.0-litre turbo straight six, wheels, and suspension tuning from the CS coupe.
This leaves the M3 CS to produce 338kW at 6250rpm and 600Nm from 4000rpm to 5380rpm. It equates to 7kW and 50Nm more than the Competition variant, which is the next most powerful M3.
The suspension is heavily based on Competition variants like the M4 CS. But software tuning of the differential, DSC, and adaptive dampers is again CS-specific.
The biggest upgrade comes with the fitment of Michelin Pilot Sport Cup 2s that hug staggered rims.
The rear forged items measure 20 x 10.0-inches while the front pair are sized 19 x 9.0-inches.
A carbon-fibre reinforced plastic bonnet, diffuser, and splitter team up with a Gurney flap to define the M3 CSís exterior, along with gloss-black tips on a sports exhaust system.
Meanwhile, inside, the centre console and stack are shared with the M4 CS, which are originally based on the M4 GTSís items, resulting in single-zone climate control and no storage between the seats. But unlike the M4 CS, the M3 version uses regular doors and sports actual door bins. All up, the car tips the scales at a kerb weight of 1585kg, just 5kg more than the M4.
Orders for the M3 CS open from January 2018. Production of 1200 units begins two months later in March. Australian pricing isnít known at the time of print, however, expect a hefty premium.
Its two-door equivalent, at $211,611, commands a $70K premium over the base M4 Pure.
