M6 is lighter than the M5?! This is true, but in real the 50Kg really dont make any difference. M6 and M5 are the same speed, only diff. is 0.1s in 0-60.

The M6 is the one that would kick R8 ass, is lighter than the m5 and reach 0-60 in 4.2 and all the way to 330 km/h.

the front looks mean engine eats other cars but the rear pretty ugly this is a suprise seeing how its german and it still has a long way to come to mercedes or bmw

yes, but you're in a big heavy saloon. a big heavy ugly saloon. Hahahaha, for some reason... R8 has just the right amount of power, looks great, and apparently handles brilliantly. Straight line speed is completely overrated, if you really wanted to just go fast you wouldnt buy an R8 or an M5.

Come to german Autobahn, do it with a AMG or BMW M, than you will see - there are no fast Audis. If you go fast for longer distances as i do every week twice (800km each tour), you will learn that there are yust three Brands beeing as fast as i am talking about. Its AMG Mercedes, BMW (M or not) and Porsches. If you meet an Audi or Volkswagen doing more than 240 Kmh, these two brands will go with you for about ten minutes, than they slow down, most because of overheating their engines. By the way, biggest Mistake of Audi was to launch the R8 with the small 4.2 V8 - having a V10 behind. Stupid Marketing .......

73091 doesnt know what the heck he's talking about. Audis are fast. Audi did happen to wimp(this website wouldnt let me use another word for that. think another word for cat) out on this thing though. the 2006-7 Corvette Z06 has 505 Horsepower. 85 more than this car. this was supposed to be a roadcar based off the Audi R8 lemans car(multiple lemans wins), but besides the looks they could done alot better. yeah its fast, but not as fast as it should be. and Im pondering how authentic this video is. the engine noise sounds like a muscle car until the very last second of the vid when u hear a flyby noise (it sounds like a supercar). even though I do think Audi made a big mistake making it how it is the four wheel drive and the technology will make up for Audi's stupid decision making.

Just saw a Test of this Thing on German TV. 0-100Kmh in 4,6s with launch-Control. M5 is 4,4s with launch-Control. Topspeed without the Limiter 301 Kmh. My M5 does 317 Kmh without the limiter, wich was measuered by the same Car-Magazine been testing the Audi today. It was Motorvision on Channel DSF. These are the Facts, so i still have enough reason to laugh about this ugly little Thing from Ingolstadt.......There really really is no reason for me to be jealous....definetley not. My big heavy 4-Door Saloon is faster than an Audi Sportscar. Hahahahahahaha.....

An R8 with 4,2 L V8 and 420 HP. So what? Never seen any Audi wich is able to go Fast on Track longer than one single turn on Nordschleife (20,8km) without Engine and Brakes going overheat. Even the for the Gallardo its hard to blow the M5. Up to about 200km/h the Gallardo is in Front, but than the M5 closes up and overtakes. So dont tell me a Audi with the 420HP Engine we know from the A4 will blow a M5. Never ever......

prolly most stupid story ever heard. this is an r8 jens. it will tear your m5 a part. so plz dont be jealous! thank you bey

For me : most ugly thing on 4 wheel i have ever seen! Plus : it is an Audi. This means : Fast on Paper, but to go realy fast on Tracks like nurburgring you have to modify the whole Car, otherwise you just burn this thing. Saw so many Audis getting lost on nurburgring because the drivers thing these things are fast. They are sometimes, but not longer than about 15 minutes, after that they need a brake of at least 1h. Most Audis look like they where fast, but they are not made to go fast. Not without mods like Brakes, Coolingsystem and so on......If you really want to go fast, buy a BMW, Lambo or Ferrari. Or best for Nurburgring is a Porsche. Stock-Audis always looses.......greetings from m5-jens.de
