Hamann hardens up Z4 sDrive35i
Z4’s classic long-nose roadster styling gets an aftermarket twist thanks to Hamann. We’ll just go for the power upgrades actually, thanks.
Just in time for the European spring (and South Africa’s approaching winter) BMW aftermarket specialist Hamann has introduced a new range of styling and dynamic enhancements for the Z4 sDrive 35i.
From its Laupheim headquarters the Swabian performance and engineering consultancy has been making BMWs go faster and look harder for more than two decades.
As drop-top motoring weather starts to return to Europe, Hamann knew it was required to have some new goodies for Z4 owners after a degree a personalisation.
New rear spoiler may keep the aft axle grounded at speed, yet it looks awfully out of place. So do the quad-exhausts.
New styling - not an improvement
Hamann’s newest styling upgrades for the E89 include a new front spoiler (redesigned to accommodate LED illumination), side skirts and a rather inelegant rear spoiler. Allegedly these new styling trinkets all do their bit to reduce axle lift at high speed.
The revised airflow management and styling kit hardly improves on the standard car’s aesthetics, with the new rear spoiler a particularly ungainly addition.
Rolling in the Hamann Z4’s wheelarches are new matt black forged wheels. These new wheels are 20-inches in diameter and roll 235/30ZR and 295/25ZR series performance rubber at the front and rear axles respectively.
A lowering kit reduces the Hamann Z4’s ride height by 30mm too, which in combination with the trick rubber should ensure improved grip levels at the cost of ride quality.
Resculptured front spoiler and 30mm ride height reduction should ensure stressful speed-bump negotiation.
Gaining a power boost from the legendary BMW N54 twin-turbo engine was always going to be relatively easy, considering the levels of latent power locked up in the 3l in-line six’s design.
Hamann’s engine technicians simply revised the sDrive35i’s ECU. This liberated an additional 40kW and swelled the peak rotational force output by a considerable 140Nm.
Courtesy of the new output peaks of 265kW and 540Nm this latest Hamann tuned Z4 is claimed to be good for a top speed of 285km/h.
How distasteful is the new Hamann Z4 styling kit? Agree or disagree here...
