Anyone with a Z4 sDrive35i (E89) wanting to experience driving pleasure at its best is likely to yearn for somewhat more power under the long bonnet and no (irritating) electronic limitation to 250 km/h and namely a full 350 hp (225 kW) is developed by the twin-turbo power plant of the HARTGE version. Moreover, software modifications to the engine control unit result not only in output being boosted by 44 hp but also in the removal of the V-max restriction.
The focal point of the car is, however, the HARTGE 'CLASSIC 3' aluminium wheels with ten spoke spider, 'Hyper Silver' finish with polished surfaces and HARTGE wheelhub caps with a black emblem and with its decorative screws, this new, one-piece, cast 20" wheel looks like a multi-part design. Dimensions include 9 x 20" with a 35 mm offset for 245/30 ZR 20 tyres at the front and 10 x 20" with a 47 mm offset for super-wide 285/25 tyres at the rear. The suspension is upgraded by fitting a set of sports springs, which lowers the Z4 by 20 mm at the front and 10 mm at the back, pretty impressive.
The new Z4 looks particularly fit with the HARTGE aerodynamic kit made of PUR-RIM and consisting of an attractive front spoiler and a perfectly integrated boot-lid lip. Naturally, both parts come with ABE (the general certification issued by the German testing authorities). HARTGE design stripes in anthracite metallic decorate the sides of the car while the carbon door-mirror casings and various HARTGE emblems underscore the overall sports look.
To minimise turbulence when driving with the top down, HARTGE has developed a special wind deflector made of splitter-proof, single-layer safety glass. All HARTGE accessories and special parts are available singularly.
