Driving experience
BMW 5 Series
Composed, refined and supremely effortless. Steering is precise and well-weighted, body control excellent, and the G30 blends limousine comfort with genuine driver involvement. sDrive keeps the classic rear-drive balance and composure; xDrive adds all-weather confidence without dulling the nose. Adaptive dampers and optional air suspension span cushioned to firmly controlled. The B48/B58 petrols are smooth and eager, the B47/B57 diesels pull strongly and stay hushed, and the 530e/545e plug-ins glide on electric power. The ZF 8-speed is quick, seamless and always in the right gear. Overall a polished executive saloon that turns a long drive into a calm, effortless one.
Peugeot 508
The W23 is the 508 that replaced the 407 with a more settled, comfortable feel. Built on the PF3 platform, it stays reasonably light for its size, so the front axle turns in cleanly and the long wheelbase keeps it planted and calm on the motorway. The conventional driving position is easy to live with, and most versions ride on a comfort-tuned rear that irons out broken tarmac. The 1.6 THP is eager, the 2.0 HDi pulls strongly and quietly, and the 6-speed automatic shifts smoothly when working correctly. It is a comfortable, easy saloon, not a sporty one.
