An m3 is about 58 inches tall, it's engine is in the front at the same height as the rotational centre of the wheels and at 1000hp it probably has about 3 times the torque of the F1 car to put down while suffering from weight transfer, worse wheelbase/track analogy...

Power/weight ratios say nothing about the roadcourse.
At the GP of Spain this year Massa took the pole position with 1:21.421
At the MotoGP of spain in the same track Rossi took the pole position with 1.41.840...

A Yamaha YZR-M1 makes about 250hp and weighs 150kg (without rider)
A F1 car makes about 900hp and weighs 600kg (without driver)

the ratios are: 1.66 for the bike and 1.5 for the F1 car yet the F1 car is 20 seconds faster...
More rubber on the ground. F1 cars always beat bikes.

Ahhh, but not nearly as stupid as your original question, which prompted it.

-You mention the tires having to be drag tires. I use them on my P-car, and my car would still outhandle your M3. Trust me on this, I've owned two M3's. Also, drag tires aren't requied. You can run r-compounds as well...which handle and stop better than any street tire on the planet. Plus, they can hook up some very serious power.

-You wanted to know which race teams are running 1,000 rwhp? 1,000 rwhp in a 3,300 lb M3 is a rear-wheel power to weight ratio of around .31. An 800 rwhp Formula 1 car, which only weighs around 1,181 lbs (minus the 150 lb driver)...has a rear-wheel power to weight ratio more than double that...at .67.

For an M3 to equal the rear-wheel power to weight of a F1 car, it would have to have 2,150 rwhp. So there you go. There's the professional race teams you asked for. Many of them, actually.



Different strokes for differeen folks. Don't knock something until you've tried it.
Actually you've just compared the RWHP of the M3 to the crank hp of the F1 car, but I get your point!

What is the fastest 1/4 miles time for an E46 M3?

Negative. The 2005 F1 cars with V-10's developed 960 crank HP...thus giving them 800 rwhp.

But yes, I'm aware the new 2.4 liter V-8's make significantly less power.

I highly doubt the conversion factor for a formula one car is that huge, you have to remember the clutch on a formula one car is about the size of a cd, as well as everything being carbon fiber etc.

You're probably right. They probably made 850+ to wheels. Thanks.

Better braking ability too (due in part to more rubber).
