For This is the cheapest version of the Z4 to buy and run, yet it delivers strong and flexible performance. You get plenty of standard equipment, too, including dual-zone climate control, leather seats, automatic xenon headlights, Bluetooth, and a USB socket (for your MP3 player).

Against An Audi TT Roadster is faster and better to drive, while six-cylinder versions of the Z4 sound sportier.

This entry-level 20i is the pick of the Z4 range, thanks to its flexible performance, agile handling and low running costs. It’s well equipped, too.

Buyer's notes

Target Price team says:

Gone are the days when you had to choose between soft- and hard-top versions of the BMW Z4. There’s now a single model that serves as both thanks to a folding metal roof which disappears into the boot in around 20 seconds.

Instead, buyers can concentrate on which of the three petrol engines they want. We reckon the 181bhp 20i is the pick of the range, because it’s the cheapest version of the Z4 to buy and run, yet offers strong and flexible performance.

If you want more performance there’s a 242bhp 28i version, which uses the same turbocharged 2.0-litre engine as the 20i version only in a higher state of tune. It’s quite a bit more expensive, though.

There are also two six-cylinder versions – the 302bhp 35i and the 335bhp 35is – but if you can afford to buy and run one of these there are better options than a Z4, such as the Porsche Boxster.
