The G-Power M5 Hurricane RS Touring is the fastest street legal wagon in the world with a top speed of 360km/h. We went to the town of Autenzell in Bavaria, Germany to meet the creators of this amazing machine and find out what it is like to drive.
Ever since G-Power was founded in 1983 the company has specialised in BMW tuning. During the 1990’s superchargers became the G-Power trademark and four years ago this led to the official partnership between supercharger manufacturer ASA and G-Power. This partnership was vital for development of the 750hp M5 Hurricane RS and Hurricane RS Touring. Both the sedan and wagon version of the G-Power M5 recorded top speeds in excess of 350km/h. Enough to bring G-Power the title for fastest production saloon and fastest estate in the world.
The G-Power Hurricane RS Touring is based on the BMW M5 Touring, of which 1,025 were built. The engineers at G-Power have taken the high-revving 5,0 liter V10 engine from the M5 Touring and equipped it with a ASA SK IIII RS twin-supercharger system and a custom water-cooled inter-cooler. The result is a power increase from 507hp to 750hp and an additional 230Nm in torque to 750Nm at 5,000rpm.
To cope with the increase in power the engine has been modified and optimized. The V10 engine receives lightweight, precisely balanced Mahle high-performance forged pistons with lower compression and increased stiffness. The standard con-rods and piston pins have been replaced by specialist parts that are able to better withstand the forces and finally the engines ECU has received optimized mapping.
To cope with the extreme top speed and 750hp the G-Power Hurricane RS Touring runs on special Michelin Pilot Sport tyres and 20 inch Silverstone Diamond wheels. Handling is enhanced by the adjustable G-Power G5-RS coil-over suspension. Our test vehicle came with large G-Power brakes that provide the desired stopping power for the two-tonne vehicle.
The brown G-Power M5 Hurricane RS Touring waiting for our arrival also has a customized brown leather and alcantara interior. This handcrafted interior gives the vehicle a very exclusive feel and the eye for detail from the materials used to the diamond pattern stitching is striking.
What G-Power likes to demonstrate with their high-speed versions of the M5 and M5 Touring is that the performance increase does not have to affect the usability or drivability of the car. When driving in town with the gearbox set to automatic you will not even notice the 750hp available under your right foot. The ride is smooth and everything feels comfortable like a normal BMW M5 Touring. But we haven’t come to Germany to check the practicality of the Hurricane RS Touring, we want to know what it can do when you push it.
The G-Power headquarters is located in a rural area in Bavaria about an hour from Munich. The hilly surroundings, quiet roads and the famous unlimited German autobahn in close proximity provide the perfect location for our road test. Once you set the seven-speed SMG into manual mode, engage the first gear through the small flappy pedals behind the steering wheel and hit the throttle the car suddenly shows the G-Power character. 0-100km/h is done in 4.5 seconds, 9.7 seconds after setting off you pass 200km/h and if you keep your foot down it will cross 300km/h after just 26 seconds. At that moment you forget you are in an estate car that weighs over two tonnes.
Under full throttle the Hurricane RS Touring propels forward like a rocket, in the lower gears each hard acceleration is a test for grip of the rear tyres. Changing gear goes fast but feels more aggressive than the standard M5 due to the massive increase in power and torque. Driving over the twisty country roads in Southern Germany the brakes don’t fail to impress, they provide plenty of stopping power for the two-tonnes Hurricane RS Touring.
The BMW M5 Touring is an ideal travel companion and can in no case be called slow. G-Power managed to take that M5 Touring to the next level with their all-inclusive Hurricane RS package, while they maintained the characteristics that made the original M5 Touring a success and that is without a doubt noteworthy.
