BMW Z4 Roadster (09 on) - Review

Review by David Ross on
Last Updated: 01 February 2010
BMW has made some key changes to the Z4 as it looks to make the two-seater more appealing to people considering a Mercedes-Benz SLK or Porsche Boxster. The biggest difference compared to the previous Z4 is the introduction of a metal-folding roof which means it is much quieter at motorway speeds. This also improves security while the cabin has plenty of space, especially in terms of head room. All the engines in the line-up deliver impressive performance and good fuel economy too, while it's usefully practical for a sports car. But perhaps the biggest improvement comes in terms of refinement and ride comfort. This makes the Z4 a coupe convertible that's easy to live with everyday.

Running costs

The Z4 proves that having a genuinely sporty two-seater convertible needn't be an expensive experience. Compared to alternatives it's decent value and well equipped while its desirability ensures it will hold its value well. BMW servicing isn't particularly cheap but the Service Inclusive is a good deal if you're buying new and covers you for five years/60,000 miles of servicing for a one-off up front payment. Other costs to bear in mind are the run-flat tyres which are more expensive than standard tyres. Insurance groups are 17 for two smaller engines while the 35i is group 18. Economy is a reasonable 31mpg to 33mpg - good considering the performance offered.

Emissions summary

Considering the performance offered, the Z4 isn't as polluting as you'd expect - both the sDrive23i and sDrive30i average 33mpg while emitting 199g/km of CO2. This is due to BMWs Efficient Dynamics programme which includes features such as Brake Energy Regeneration that recycles what would otherwise be lost energy, to save fuel. Even the powerful 35i model returns a useful 30mpg and emits 219g/km of CO2. Opting for an automatic model sees these figures improve further.
