M5 or RS6

It really depends what you want. The RS6 looks to be an amazing car. 580hp projected but it will cost at least 10 grand more than the M5. From reading the M5 board, audi's have a bigger drivetrain loss than BMWs do. If you would like to reference this, check out the m5board.com. There are at least 6-7 pages of discussion aboout the new RS6 vs the M5. I know that the Audi has been using an M5 to do tests for the RS6 there are producing. Not to sure when the RS6 will be available but the one highlight will be the DSG (a better SMG transmission). Hope this helps.

GREAT SUCCESS!!!!

I've been driving Audi's for 15 years, and in the last 5 years have switched to BMW's. From my perspective, Audi is making some of the best cars on the planet right now. Their interior/exterior styling and fit/finish is unsurpassed. If you live where it snows a lot, the Quattro is the best AWD system as well.

The reason I switched to BMW is simple - I wanted the best driver's car. BMW's are lighter, better balanced, and the handling is superb. Audi's are heavy cars that suffer from a 60/40 weight distribution. I've tracked a few, and they plow terribly in the turns. Check out the latest Car and Driver comparison - the BMW 335 outran the Audi RS4 on the VIR track.

The RS6 will be a great car, and if it really has 580 HP (I doubt it will), then it will probably be slightly quicker in a straight line than the M5. Quattro has about 7% more drivetrain loss, which would be about 40 HP, and the car will weigh around 4300 lbs, so it will be very close to the M5 in whp/weight ratio. But even if it makes it around the 'ring a few seconds quicker, I can guarantee it will be nowhere near as much fun to drive.

No contest for me. M5, and now that BMW are selling the M5 Touring there is no reason to look to Audi to haul the dogs around in style.

The BMW with its RWD and better balance would be my choice unless I lived in the Alps where the 4wd might come in handy now and then.

Unfortunately, the M5 touring is not available in the US.

All I can say is: 'Leider nicht hier drüben bei uns...'
