The Z4 M Coupe is priced to compete against the Porsche Cayman S, but we don't expect the BMW to hold onto its value as the ultra-desirable Porsche. The Si is a less hardcore but still sharply focused rival for the Nissan 350z and top Audi TT. What's especially impressive, given the performance, is the fuel economy.
BMW Z4 Coupe quality & reliability
Leather sports seats and a carbon fibre-look or aluminium trim aside, there's little to mark the Coupe out from humbler Z4 models, but that's no bad thing. The cabin is well built from first-class materials, and looks as though it should stand the test of time. Early M Series engines in the 3 Series suffered some catastrophic failures, although most were replaced under warranty. BMW claims the latest engines are vastly stronger.
BMW Z4 Coupe safety & security
All Z4 Coupes come with plenty of kit to help you avoid an accident, including massively powerful brakes and an electronic stability system to curb unruly behaviour in corners. Twin front and side airbags are standard, but curtain airbags are notable omissions. An alarm and an immobiliser are fitted to help deter thieves.
