Driving experience

Audi A3

Quiet, precise and easy to drive quickly. The A3 steers accurately with a light, consistent weighting, rides well on its standard suspension, and stays hushed at motorway speeds. Front-drive versions are neat and predictable; quattro adds strong traction out of corners and on poor surfaces, particularly on the 2.0-litre cars. The 1.5 TFSI is the pick — smooth, economical and quick enough; the 2.0 TFSI adds real pace; the 2.0 TDI is the sensible high-mileage choice. The S tronic is sharp; the manual is light and precise. Body control is good, though the A3 is tuned more for comfort than for entertainment.

Mercedes-Benz A-Class

Refined, techy and effortlessly easy to live with. Steering is light and accurate, the ride composed and hushed, and the A-Class feels grown-up and planted on the move. Front-drive is safe and predictable; 4MATIC adds all-weather security on the faster versions. The M282/M260 petrols are smooth and eager, the OM654 diesels pull strongly and stay quiet, and the A 250 e plug-in glides on electric power. The dual-clutch shifts quickly and smoothly. Overall a calm, tech-rich hatch that majors on comfort and connectivity.
