I can't understand one thing, it seems to me very strange,recently has been posted test between BMW M5 G-power and Audi Rs6 MTM, i can't believe in reality of this test. i've seen on youtube bmw m6 g-power 730 HP 0-300km/h accelaration on speedo and compared it with Audi Rs6 evotech( several are in Russia,Moscow from Dragtimes.info) 730-750HP with no catalizators. so the video is here http://www.dragtimes.info/forum/showthread.php?t=895 in which very obviosly (if calculated) seems that Gray Rs6 sedan has acceleration exactly 1 second better compared to G-power,there is also another video of this particulary Gray Osmans (The name of driver) Rs6 0-300km/h and the speedo result shows the same as i linked... explain me just one thing,why Rs6 has lost in autobild test 8 seconds till 300 km/h???????? it's unreal...
