Car reviews

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.
