Oettinger is a German tuner specialized in creating incredible, super fast cars from German Hot-hatches. The latest he worked on is a magnificent Audi RS3 Sportback and after remapping the engine, changing some internals, improving turbochargers and giving it a full engine makeover, the 2.5-liter engine in this car was dialed up to 520hp. The results can be seen in this video where the Audi RS3 hits 62 mph in insane 3,4 seconds.
That was really over the top. What do you think of this next video?
