2009 G-Power G4 Z4 news, pictures, and information

G-POWER G4 3.0i EVO III: The true 'M'?

300 km/h top speed, 0-100 km/h in just 4,9 seconds, 375 hp and an engine's peak torque of 420 Nm: These are the characteristics of the latest G-POWER development for the BMW Z4 3.0i.

In addition to the increase in power output of 144 hp for the 6- cylinder engine, that normally produces 231 hp, the G-POWER offers a complete tuning program for the Bavarian roadster consisting of: Aerodynamic body kit, light-alloy wheels, suspension modifications, high-performance brake system and exclusive interior components.

G-POWER offers superchargers system for increased power output lòòking back on 25 years of experience in tuning BMW automobiles. The new G-POWER EVO III supercharger system is an evolution, based on the well known systems for the Z4 2,2 to 3,0 l six- cylinder engines of the BMW Z4. Its core is an ASA T1-12 supercharger from the all new 'black-line' edition that features ceramic ball bearings for an increased rpm limit of the charger. Accordingly the boost rises to a higher pick of 0,6 bar rel. , which is cooled down by a large air-to-air intercooler and controlled by an Dual Flow bypass system. To keep the oil temperatures at level the G-POWER EVO III system is equipped wîth a thermostat controlled oil cooler, that prevents the ASA supercharger from overheating. On the exhaust side the G-POWER EVO III system features a complete exhaust system wîth racing-headers and catalysts. This measure optimizes power yield, throttle response and also ensures the engine's thermal health. Specially developed mapping for engine electronics coordinate the perfect interaction of all new components.

The results of the G-POWER treatment are impressive: With 375 hp at 6.450 rpm and 420 Nm torque at 4.650 rpm the standard 231 hp strong BMW Z4 3.0i becomes a true eli'M'inator. With a sprint time from rest to 100 km/h of 4.9 seconds and to 200 km/h in 15,1 seconds the G-POWER G4 is at level wîth the BMW Z4M and finally outruns it wîth a top speed of 300-km/h. The conversion of the standard engine to the G-POWER EVO III configuration is 18,850,00 Euro including the installation; which can only be done at our headquarters' workshop in Autenzell Bavaria.

The enormous performance places extreme demands on aerodynamics, tires, suspension and brakes. The G-POWER front apron replaces the production part in its entirety. Its large air inlets provide optimal supply of cooling air for the high performance air-to-air intercooler. At the same time the spoiler minimizes lift on the front axle at high speeds. The G-POWER rocker panels smooth the airflow between the wheel houses and give the Z4 a longer, lower and sleeker appearance. Lift on the rear axle is reduced by the G-POWER rear apron, that features the needed openings for the 4 pipe G-POWER rear muffler.

The G-POWER Silverstone 20-inch light-alloy wheels that fill out the space beneath the wheel arches perfectly, underline the distinctive new look of the G-POWER equipped BMW Z4, are mounted in sizes 9.0 J x 20 wîth size 245/30 ZR 20 tires in front and size 10.0 J x 20 wheels wîth size 285/25 ZR 20 tires on the rear axle.


The large wheels make room for the G-POWER high-performance brake system wîth eight-piston fixed calipers and 380 x 34 millimeter brake discs on the front axle. The Z4 handling can be made even sportier by installing the height-adjustable G-POWER coil-over suspension RS wîth nine selectable settings each for bound and rebound.

The G-POWER EVO III supercharger system is available for all BMW Z4 3.0i wîth manual transmission, along wîth the numerous items from the extensive G-POWER tuning accessories lineup.
