For Sale: BMW Z4 with 551HP M5 V10 Engine

Germans love power and speed. While most of us would have been more than content with a stock BMW Z4 M, the owner of this Z4 that's for sale on a German online vehicle marketplace found that an inline-six with 343 HP couldn't satisfy his lust for speed. So what more reasonable than to throw in a BMW M5 / M6 sourced 5.0-liter V10 engine. But even the M5 V10's 507 HP weren't enough for our German protagonist who decided to replace the Z4's inline-six with an even more powerful, Hartge-prepped version of the V10 delivering a hefty 551 HP. The engine is mated to a six-speed manual gearbox.

Aside from a set of Hartge 20-inch alloy wheels, the Z4 V10 is all stock on the outside. The asking price for the V10-powered German roadster is a not-so-easy-to-swallow, 97,900 Euros which comes to about $137,700 US with the current exchange rates.

G-Power BMW M5 Hurricane RS: Fastest Production Sedan in the World

The new G-Power prepped BMW M5 Hurricane RS has obtained the bragging rights for the fastest street-legal sedan in the world after it broke the long-standing record of the BRABUS Mercedes-Benz CLS Rocket. In November 2008 the 750 HP strong G-Power M5 Hurricane RS achieved a new top speed of 228,4 mph (367,4 km/h) at the ATP High-Speed test track in Papenburg, Germany. Compared to the 'standard' 730HP M5 Hurricane which has been clocked at 223.8 mph (360 km/h) earlier in 2008, the RS features ASA two modified superchargers with enlarged capacity.

And this will not be the last time that we are hearing about the M5 Hurricane as the folks over at G-Power believe that the Bi-Kompressor system has not yet reached its limits. According to Christian Stöber, the firm's CEO, the V10 engine can handle even more boost.

G-POWER M5 HURRICANE achives a 228mph top speed

G-POWER has done it again. The M3 Hurricane can now be named the fastest sedan in the world, breaking a long-standing record of the Brabus Rocket. Back in March, we wrote about G-Power’s tuning program, named “Hurricane”, and also about their 730 horsepower M5.

At the time, the M5 ran the track with a top speed of 200 mph, but G-Power had bigger plans for their M5. In November 2008, G-POWER M5 Hurricane RS achieved a top speed of 228.4 mph (367,59 km/h). The previous 227.2 mph (365,7 km/h) hold by the Brabus, has been broken. The test took place on tracks in Papenburg.

While the Brabus has a V12, G-Power uses only a simple V10 from the shelves of BMW and modified this engine with other two superchargers from G-POWER’s technology partner ASA, with enlarged capacity.

According to G-POWER the BI-Kompressor system could be raised from 0,7 bar rel. to 0,8 bar rel., but the system has not reached its limit yet. Companies representatives confirmed that if needed,  the system could be improved and the M5 Hurricane could be taken to a whole new level.

Which level that might be, time will tell. We’re almost positive that Brabus has something in-works to regain the lost status.
