Well-that is the issue. I have done Duisburg-Berlin in my B8 in less than 3 hours for 550 kms on a sunday morning once...including refuelling and breakfast. To make these average speed you have to drive 250 km/h and more every time you can do it. My measured rear-axle temperature was above 125 degrees celsius.

But thats not the real issue on the G-Power car....

The M-GmbH has built one of the finest free breathing machines on this planet. A 5-Litre, 507 hp, 500 Nm, more than 8000-rpm Monster with an extremely high compression ratio. Packed with a 7-speed SMG 'box, controlled by a computerized Motormanagement and Drive Management with hundreds of possible settings.

Now a small company comes up, bolts 2 turbochargers on this monster machine, gets nearly 50 percent more horsepower, a lot of more torque and so on.

You won't tell me that this car is as bullet proof as a normal M5? That all the needed work is done to make all the systems work properly? Lets think of maybe 20 cars that will be sold-even the high price-tag on the car wouldn't nearly pay the price of these hours.

a friend of mine does a lot of BMW-conversions here in Germany-lets say I have seen a lot of Hartge H50s near Aachen the last years...and he has performed one H50 5.0 Compressor conversion-despite a lot of money spent this car never really drove as it should have. And this conversion based on a normal 4.4 litre....

In these days it isn't easy to get 50 percent power out of a Machine like the M5 E60.

For me the car is a show-car and will be a show car in future...

just my 0.02 D-Mark


Hubraum ist durch nichts zu ersetzen- außer durch noch mehr Hubraum...

Fair comments imho. I own a s/c'd M5, and I can tell you that it required a lot of R/D to get the car to run right. It is still a bit fickle at times, although I'm still crazy about it. Another experience we might look to is Dinan's work on the S3 . Dinan spent an enormous about of time getting the car to run right. By 'right' I think we mean seamlesslly integrated and 'OEM-like'. Happily, the goal was achieved.

The point being that it is one thing to bolt on FI horsepower, quite another challenge to make it OEM feeling. Hopefully a member (or magazine) has the opportunity to really evaluate the car and give an objective review. Until then, I guess we have to assume G-Power has put in the many hours of testing and tweaking that would be needed.

I totally agree with you except that WHERE ON EARTH COULD YOU OPEN UP THE THROTTLES without going back in time? The car is ungodly fast as is....but nice to know that there is more power available!
