BMW Z4 Coupe

WHAT IS IT?

It's the tuned, fully clothed and brutally quick version of BMW's two-seater roadster.

WHY SHOULD I BUY ONE?

Why spend £1500 more on the drop-top when the sun only comes out for two days a year?

WHAT ARE THE ALTERNATIVES?

It's an all German affair, with only Porsche and Mercedes able to match the BMW's grunt, looks and build quality.

RANDOM FACT

The Z4 M Coupe features BMW's Variable M differential which uses a pump to generate internal pressure, then transfers power via a clutch to the wheel with most grip.
