Notes:

All weights for any specific vehicle will vary according to standard and optional equipment fitted. A weighbridge must be used to determine specific weights. The Urban fuel consumption figure is based on typical city driving, including starting the car from cold. The Extra Urban figure is based on typical motorway driving and cruising. The Combined figure averages the consumption across both cycles.

All optional specifications at extra cost. All weights and dimensions are average figures for standard vehicles. All specifications are subject to change without warning but are correct at the time of going to press.
