BMW Z4 M (06-08) - Review Review by David Ross on 12 Sep 2007 Last Updated: 28 Oct 2008 3.5 The Z4M Coupe and Roadster are the fastest models in the Z4 line-up, powered by a 3.2-litre six-cylinder engine with 343bhp. Summary Driving & Performance Equipment Comfort Costs Safety & Reliability Buying & Selling Owners' Reviews Also Consider Facts & Figures Company Car Info Gallery 2 out of 5 Comfort View full gallery The Z4M is available as a coupe or a roadster but whichever bodystyle you opt for it's a strict two-seater with a cosy, intimate cabin. Although there's decent room for either occupant it can quickly start to feel claustrophobic on long journeys, but it's the crashy ride which is the biggest let down - it means the Z4M is rarely comfortable as a driver or passenger and the suspension soon highlights poorly surfaced roads. There’s no lumbar adjustment on the seats either and the seat back and isn't height adjustable, which may be uncomfortable for taller drivers. At higher speeds there's also a lot of tyre and road noise 2.5 out of 5 Practicality View full gallery The boot capacity is less useable than the standard Z4 due to the relocation of the battery to the boot, which takes a 40-litre bite out of the overall capacity and makes it a more awkward shape. It means it's hard to carry traditional rectangular hard suitcases for a weekend away. The coupe has slightly more space than the roadster and if you release the luggage cover and don’t mind losing the view out the back window, it will carry a fair bit more. There are a number of storage areas between and behind the seats, as well as the glovebox and small bin in each door. Get a BMW Z4 M valuation How does the boot space compare?

The driving position feels pleasingly sporty, but when it's dark and rainy the low seating position and long nose make it feel less manageable and harder to judge when parking or attempting three-point turns. Build quality is excellent though and all the controls and switches are clearly laid out.
