A review of the BMW Z4 roadster

At a price point of £27,615 to £45,815, the new BMW Z4 represents a step forward for the range. How so? Well, the fabric roof has been replaced with a retractable metal top, and there has been some tweaking in the bodywork to give the car a much sleeker look.

This new model has been transformed from coupe to convertible, which makes it a whole lot more fun to drive and with an all new suspension, the Z4 has been designed to give comfort and excitement in equal measure. Although it is not an out and out performance machine like Porsche's Boxter, the Z4 has the bonus of being the sort of motor that can be used on a daily basis because it glides over road surfaces with relative ease.

The Z4 entry-level model can go from 0-62mph in 7.9 seconds, but for faster acceleration the Z4 sDrive 35is will get from 0-62mph in a commendable 4.8 seconds.

Elsewhere, BMW have clearly thought long and hard about kitting out the car with a raft of safety features. This is a strong and reliable car that comes with electronically controlled stability management, traction control, airbags galore and anti-lock brakes.

Not surprisingly, such comforts come at a price. The Z4 is not a cheap motor, but if you are comparing it to its main competitors, Mercedes and Porsche, the entry-level sDrive 18i is less expensive to buy than their equivalent entry models. Additional options are numerous, but basic models are not so bad and come with climate control, leather seats and 17-inch alloys, so are pretty impressive.

Expect 42.5 mpg at best from the Z4, and bear in mind that there is no diesel available in the range. Fuel stats not withstanding, this Z4 benefits from the same strong re-sale power that BMW are famous for, so should represent a decent investment opportunity for anyone prepared to meet the asking price.
