Driving experience

Audi A4

What defines the B9 is how quietly it gets on with the job. The cabin is hushed, the ride composed, and quattro ultra shuffles torque between the axles without ever letting on, giving a planted, almost understeer-free security. Steering is accurate but deliberately light and never asks much of you. Engines are the real story: the 2.0 TFSI is brisk and tractable, the 2.0 TDI the sensible long-distance choice, and the 3.0 TDI V6 pulls like a locomotive with the manners of a far larger car. The S tronic snaps through gears crisply; the tiptronic simply dissolves them. What you give up in steering feel you win back in effortless progress.

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.
