Well, the press release says "at least occasionally". In an effort to emphasise the seeming discrepancy between estate cars that blend in with the background and performance capable of truly taking flight, ACS has, in the first case, significantly increased power.
50bhp from a 3.0 litre turbocharged straight-six engine, according to BMW, is more than enough for the M3 Touring. With its "Stage I" software, ACS has increased it to 582 bhp and 553 lb-ft of torque, or the full 602 bhp with "Stage II," both of which are made possible by a new ECU.
Together with the quad rear tailpipe system, Stage II also features a new stainless steel exhaust setup that promises "a loud, sporty sound with increased exhaust flow" (Stage I's was optional).
Also improved road flow thanks to enhanced suspension. There is a new spring kit that lowers the M3 Touring by 15-20mm up front while maintaining the stock M springs in the back. The "RS Coilover" system introduces redesigned dampers with height, compression, and rebound adjustments.
According to reports, the latter option mimics the factory settings for the M3 Touring, with "soft understeer" at the limits and "good-natured" load shift reflexes.
The RS Coilover configuration, on the other hand, stands out because it provides "much greater cornering speeds with utterly comfortable everyday handling."
A new front splitter, front side "wings," new side skirts, a rear roof spoiler, which is said to add 20 kg of downforce, and a few trim pieces are among the new aerodynamic components. The interior is also accessorised with footrest, pedals, and paddles made of aluminium. Alcantara and leather, oh, and plenty of it.
