Video: BMW M3 CS roaring on the ‘Ring

Media reported last month that the new BMW M3 CS was already in development, and the latest spy video filmed at the Nürburgring confirms it.

The footage reveals a rather impressive engine soundtrack generated by an inline-six turbo with three liters of displacement. The power figures aren’t here yet, but we expect more than 500 hp (373 kW) and 600 Nm (443 lb-ft) of torque.

Aside from improved performance, the BMW M3 CS should get a range of other updates as well, including adaptive suspension, an M differential, a new exhaust system, tweaked steering, and carbon-fiber hood and roof.

The interior will be well-equipped with lightweight bucket seats and a luxury leather/Alcantara trim combo.

The launch is expected before the end of the year.
