BMW - 5 Series

The 5-Series followed the controversial new 7-Series with its angular, sculpted body and bulky rear end, but is less awkward-looking especially in Touring estate form. BMW also developed its fiddly i-Drive control system for the 5, and whilst it's still not easy to use, it's an improvement. The 5 also debuted Active Steering: a speed-sensitive set-up that alters both power assistance and steering ratio, which can feel somewhat disconcerting at first. Luckily, that's optional, if it's too much like technology for its own sake.

With impeccable road manners rear end slippage is kept under control by an armoury of electronic aids unless the driver really overdoes it and impressive levels of refinement, the 5-Series is a consummate all-rounder and more exciting to drive than an E-Class. The diesel engines are superb, and even the base 520i petrol model is a capable motorway cruiser. The 545i V8 makes a 7-Series seem unnecessary.
