BMW's 5-Series Gran Turismo is an unorthodox but impressive addition to the range. Steve Walker reports

That the 5 Series Gran Turismo is targeting a more luxurious end of the market than the 5 Series saloon is confirmed by its use of underpinnings from the 7 Series. Double wishbone front suspension is combined with an air-sprung multi-link rear. There's also the option of Integral Active Steering, the rear-wheel steering system found on the 7 Series which improves the handling and low-speed manoeuvrability of these substantial cars. BMW's Adaptive Drive System is also available, allowing owners control over the suspension settings and the roll stabilisation functions.

Virtually any way you care to measure it, the 5 Series Gran Turismo is bigger than a 5 Series saloon. The benefit of the Gran Turismo's increased dimensions is felt inside where despite the elevated seating position, headroom is on a par with that of the X5 and rear passenger space compares to that in the 7 Series. There's also a decent boot capacity of 440-litres, extended to a huge 1,700 litres by folding the seats down, which is accessed through the Gran Turismo's trademark two-piece tailgate.
