Driving experience

BMW 3 Series

Precise, balanced and still the class benchmark to drive. Steering is quick, accurate and communicative, body control taut, and the rear-drive chassis stays planted yet adjustable through bends. sDrive keeps the classic 3 Series balance and a hint of playfulness; xDrive adds all-weather grip without dulling the nose. The optional adaptive M suspension spans comfortable to firmly controlled. The B48/B58 petrols are smooth and free-revving, the B47/B57 diesels pull strongly and stay refined, and the 320e/330e plug-in hybrids glide silently on electric power. The ZF 8-speed is quick and seamless; the early manual is a rare, engaging treat. Overall a poised sports saloon that blends sharp dynamics with everyday comfort.

Peugeot 508

The R83 wears a four-door coupé suit but rides the EMP2 bones of a family saloon, and that mix defines it. It sits low and wide, so the front axle feels keen and the car tracks calmly through corners, while the long wheelbase keeps it planted on the motorway. The small i-Cockpit wheel and raised dials are the most extreme Peugeot has done and demand a real acclimatisation; once settled, the steering is quick and accurate and body roll stays well held. Most versions ride on a comfort-tuned rear that smothers broken tarmac, though big wheels and firmer GT/PSE damping add some fidget. The 2.0 BlueHDi pulls strongly and quietly, the PSE is properly rapid, and the EAT8 automatic shifts without drama. It is a composed, comfortable fastback, not a sports saloon.
