If anyone wonders why Finland produces som many world class rally drivers... just look here. This is how they school their young drivers.....

What engine is he running? In the front it sounds like a BMW Inline 6...classic sound...but at the rear... holy crap.. like a mixture of an rotary and 2JZ....love that! Maybe it is a normal BMW Inline 6...I would like to see the exhaust work. I want that sound to on my M50...
