This is real speed. And even at 170 mph, it's legal. Thank you, German Autobahn.
At the wheel of this Audi RS7 is JF Musial. He's driving across Germany, pointing out their simply superior driver training and highway 'keep right/pass left' discipline. That means that this 170 mph flyby is totally within the law, and he can post full in-car video of it to YouTube without getting arrested.
It's all for his most recent episode of DRIVEN, where he goes into more detail on the difference between driving on the highway in the US and driving on the Autobahn in Deutschland. Watch the whole thing right here.
