Although many Americans remain unfamiliar with the Alfa Romeo brand, a Giulia Quadrifoglio has the potential to make or break the Italian firm in the U.S.

Appealing to the upper-end of a market and to those customers that generally know their stuff, a high-performance sedan aims to shake up the established German hierarchy and according to some reviews, is a new benchmark.

On paper, Alfa Romeo says that a model’s 2.9-liter twin-turbocharged V6 engine delivers 503 horsepower, identical to the output of the Mercedes-AMG C63 S.

However, on the dyno, how does that figure translate to a road? Well, one U.S. Giulia Quadrifoglio owner recently strapped the car to the dyno where it managed to deliver 392 horsepower and 389 lb-ft (527 Nm) of torque at the rear wheels.

Such the horsepower loss is perhaps slightly more than you would expect with the typical 15 per cent driveline loss but the uploader notes the car was tested on the Mustang AWD dyno, a setup known for delivering lower figures than many other dynos. Active aero deployment was cool to watch. Just watching the car carve up a twisty country would be great.
