This one, the new BMW M4 CS, will join an already expanded group that includes the M4 Pure, the M4 and the M4 Competition.
The CS badge makes its return after having last been seen in 2005 on the E46 M3 - for the UK only - and before that not since the '70s and '60s.
Where the other $139,900 to $165,900 M4 models make either 317kW or 331kW with 550Nm, and the nearly $300,000 M4 GTS offered a meaner 368kW and 600Nm, the M4 CS lands somewhere in between with 338kW, 600Nm, and a $211,610 price tag (before costs).
Power is sent to the rear wheels through a seven-speed dual-clutch transmission only - no manual available for this one - and the auto benefits from its own oil cooler.
For the spend, you get the bigger numbers and a lighter design - shaving between 10 and 32kg off the others in the range, thanks to a liberal use of carbon-fibre reinforced plastic (CFRP) with an all-new CS-specific front splitter, bonnet, roof, spoiler lip and rear diffuser.
All of this, along with the M Driver's Package and the Active M differential, leads to a claimed 0-100km/h time of 3.9 seconds, just 0.1 off that of the GTS. Top speed is electronically limited 280km/h.
BMW also notes that, thanks to all of this - and a CS-specific suspension tune - the M4 CS claimed a Nurburgring Nordschleife lap time of 7m38s, a 22-second improvement over the regular M4.
BMW says the M4 CS isn't just a performance-focused offering, though, pointing to trim features like Alcantara in the cabin, along with Walknappa leather and Nawaro natural fibres.

The performance nods are there, though, with a lighter single-zone climate control system - as a compromise between dual-zone and dropping it altogether - along with leather pull straps on the inside face of the doors. There's still a 12-speaker audio system, although BMW says it's been specially modified for this low-weight project.
The grey alloy wheels, 19-inch at front and 20-inch rear, are a new light-weight design specifically for the CS. These are wrapped in Michelin Pilot Sport Cup 2 tyres measuring 265/35R19 up-front and 285/30R20 at the rear - the same type and configuration used for the GTS.
An M Compound Brake setup features, with four-piston front brake callipers matched to two-piston rears. M Ceramic brakes can be optioned at a huge $15,000, with six-piston front and four-piston rear callipers included.
Other standard kit includes:
- Head Up Display with specific M contents

CarPlay is a $623 addition, and Android Auto is not available.
The M4 CS will be officially available in Australia later this year, although exact delivery dates are still to be confirmed.
