The 2019 BMW M4 CS is a track-focused, limited-production coupe that bridges the gap between the M4 Competition and the more hardcore M4 GTS. It features a 454-horsepower TwinPower Turbo inline-6 engine, a 7-speed M DCT transmission, and extensive use of lightweight carbon fiber components for enhanced performance. Key highlights include a specially tuned chassis, Adaptive M Suspension, Michelin Pilot Sport Cup 2 tires, and a motorsport-inspired interior with Alcantara and carbon fiber elements.
