The BMW M3/M4, Mercedes-Benz C63 and Audi RS4 are all limited to 155 mph (250 km/h) due to a long-standing agreement between Germany’s three automakers to limit the top speed their performance cars.
Such an agreement doesn’t exist in Italy, so when Alfa Romeo was developing its new 505 horsepower Giulia Quadrifoglio Verde, engineers left the top speed limiters on the drawing board and decided to let the production car stretch its legs all the way to 190 mph.
A YouTube user recently decided to put the Giulia QV’s claimed 190 mph top speed to the test on an unrestricted section of the Autobahn. He managed to reach 289 km/h, which is equivalent to about 179 mph. There’s still some air left in the Giulia QV’s lungs at that speed, but traffic eventually forces the driver to end his rather risky test early.
