Overview
- The CS uses a reworked 3.0‑litre twin‑turbo straight‑six rated at 530 hp and 650 Nm, driving the rear wheels through an 8‑speed automatic.
- It sheds about 30 kg versus the standard M2 to roughly 1,710 kg through carbon‑fibre parts including the roof and boot lid.
- Chassis changes target track use with an 8 mm lower ride height, M‑specific tuning for springs and dampers, and recalibrated stability systems.
- BMW quotes 0–100 km/h in 3.8 seconds and a 302 km/h top speed, matching the larger M4 Competition’s output figures.
- Design and cabin updates include staggered 19/20‑inch forged wheels, an integrated ducktail spoiler, M Carbon bucket seats, a 12.3‑inch cluster and a 14.9‑inch touchscreen.
