Driving experience

BMW M4

Powerful, refined and highly engaging. Steering is precise, body control is excellent and the car feels planted and involving. Rear-drive versions retain classic M balance and playfulness; xDrive versions are more neutral, secure and quicker off the line. Adaptive M suspension offers a wide range between firm and acceptable comfort. The S58 is strong, free-revving and characterful with excellent mid-range and high-rev performance. The manual (base) is engaging; the ZF 8-speed (Competition) is quick and smooth. Overall a focused high-performance coupé that balances dynamics with modern refinement.

Mercedes-Benz CLA

Comfortable, quiet and far more grown-up than the C117. The C118 rides with better isolation and body control, steers accurately, and feels closer to a proper Mercedes inside. Front-drive versions are easy; 4MATIC adds traction in poor conditions. The M282/M260 petrols are smooth and eager, the OM654 diesel is the long-distance pick, and the 250 e plug-in covers short trips on electric power. The dual-clutch is smoother than before, though still occasionally hesitant at low speed. It is a much better all-rounder than the first CLA, with the same coupé styling and fewer of the compromises.
