BMW's muscular Z4 Roadster is one of this year's
more interesting newcomers.
Its bold, aggressive styling, a radical combination of creases
and curves, is not for the introverted. This car attracts attention
like few others.
The Z4 replaced the more retro Z3, a car that failed to live
up to expectations. BMW's second effort is a much sharper package,
both in looks and handling. The Z4 makes a much stronger statement.
The test car was a 2.5i automatic. Apart from the styling, the
most noticeable change is the handling. The Z4 is more sure footed,
sits flatter and hangs on more tenaciously. The extra grip can
be attributed to a much more rigid chassis and revised suspension.
There is now a sharpness and sparkle to the handling which wasn't
evident on the Z3, making it a much more involving car.
For some, on rougher surfaces, the rear end may be a little too
firm but the rear suspension is tuned to give the car a dynamic
feel.
It takes some time to get used to the electronic power steering
which is very direct. The steering feels light at low speeds but
does load up as the revs increase.
The five speed Steptronic automatic transmission is competent
enough for those who want the convenience of a self shifter but
in a car as small as this, especially with the smaller engine,
a manual shift would have been a better and more rewarding choice.
Those wanting performance to match the Z4's aggressive looks
should probably consider the 3.0 litre engine. But the Z4 2.5i
is by no means a slouch - it scoots from 0-100km/h in 7.5 seconds
- but the auto transmission robs the roadster of a little zip.
The contemporary lines carry through to the interior which is
bigger than its predecessor but is still by no means expansive.
The canvas roof seals tightly and can be raised or lowered at
the push of a button. On coarse gravel the 16-inch Bridgestone
Potenzas are noisy. Speaking of tyres, the roadster is yet another
new arrival which does not carry a spare. In the eyes of most
Australians, that's a black mark.
