Driving experience

Mercedes-Benz GLC

Comfortable, quiet and more car-like than its height suggests. The GLC steers accurately with light, consistent weighting, rides well on the standard suspension, and stays hushed at motorway speeds. 4MATIC is standard on most versions and adds sure-footed traction without altering the relaxed character. The M274/M264 petrols are smooth and willing, the OM654 diesel is the economical distance choice, and the 300 e plug-in covers short trips on electric power. The 9G-Tronic shifts unobtrusively. It is a well-rounded, easy-to-live-with compact SUV that does everything competently.

Renault Arkana

A comfortable long-distance cruiser rather than a dynamic driver's car. Steering is light and accurate enough for daily use, and body control is reasonable, but the ride is firmer than many rivals — especially on larger wheels — and can feel unsettled over sharp bumps. The 1.3 TCe feels responsive once moving, while the E-Tech hybrid prioritises efficiency and can feel less linear under hard acceleration because of its multi-mode transmission. The EDC dual-clutch is smooth at higher speeds but can show low-speed hesitation or judder.
