Eye-watering 405kW track-ready performance wagon arrives: 2025 BMW M3 CS Touring leaves Audi RS4, Mercedes-Benz C63 AMG in its dust

BMW has revealed an even more souped-up version of its M3 wagon model, the M3 CS Touring.

Staging its global unveil at the iconic Mount Panorama circuit in Bathurst, just 55 vehicles have been allocated locally with each set to carry a price tag of $253,900, before on-road costs, a $70,400 premium over the standard M3.

It boasts the same twin-turbo 3.0-litre in-line six-cylinder engine as its M3 namesake, with power and torque still transmitted to all four wheels through BMW’s sport-focused, semi-automatic eight-speed Steptronic transmission.

Some model-specific powertrain tweaks do see power climb by 15kW to 405kW, while peak torque remains at 650Nm.

The bump in power comes thanks to a greater charge pressure on the M3’s two mono-scroll turbochargers to 2.1 bar, while a springier engine mount delivers sharper engine responsiveness and gear shifting.

Additionally, BMW have also tweaked the suspension, steering and integrated braking system, while increasing body rigidity with a M front-end strut brace in the engine compartment.

M Compound brakes, with red calipers, add much-needed stopping power. Customers can alternatively opt for M Carbon ceramic brakes for a premium.

The M3 CS Touring comes equipped with M-light alloy wheels in an exclusive double-spoke design which comes in either a matte Gold Bronze or black finish.

They measure 19-inch at the front and 20-inch at the rear and come wrapped in 275/35 ZR19 track tyres. Customers can opt for sports tyres as a no cost option.

Weight-saving materials such as carbon-fibre reinforced plastic (CFRP) clad the exterior and extend into the cabin.

That includes on the car’s bonnet, front splitter, front air intakes, exterior mirror caps, rear diffuser, as well as the centre console, M carbon bucket seats and steering wheel-mounted shift paddles.

The various power-boosting and weight-saving measures ultimately decrease the M3 CS’ weight by 15 kilograms compared to the standard M3, while bumping its top speed by 20km/h to 300km/h. 0.1 of a second is also shed from the M3's claimed zero-100km/h time for a sprint time of 3.5 seconds.

A titanium exhaust with matte black tail pipes also make it sing louder than before, while a high-gloss roof and spoiler set it apart design-wise from the regular M3.

Other notable model-specific features include an Alcantara steering wheel with CS badging that also extends to the door sills, seats and centre console, along with full-leather merino upholstery.

The M Drive Professional system also adds a drift analyser, lap-timer, shift light notifier and a tyre pressure and temperature gauge to the digital driver’s display, which is the 12.3-inch unit carried over from the standard M3.

So too is the 14.9-inch central multimedia display, which includes wireless Apple CarPlay and Android Auto connectivity, wireless charging and a head-up display.

Customer deliveries of the M3 CS Touring will commence from mid-2025.
