From 505 horsepower to 443 pound-feet of torque promise to 392 horsepower and 389 pound-feet of torque dyno results, clearly, there is a big difference. There is a difference of 116 horsepower and 51 pound-feet of torque to be exact or 22 and 12 percent difference in horsepower and torque accordingly. Given these facts, it begs the question of whether the test was reliable or not.
The 2017 Alfa Romeo Giulia Quadrifoglio’s 35 psi of boost is also noteworthy as it aids in achieving the power and strength it is expected to deliver. It also comes with a cylinder deactivation, a technology the car manufacturer is proud of because it promises 15 percent improvement in its fuel economy.
The eight-speed automatic transmission and flat torque curve of the 2.2-litre diesel (more than 331 pound-feet of torque is available between 1,500 and 3,000 rpm) ensured it almost catapulted along the next straight stretch of asphalt.
The engine is perhaps a little noisier than four-cylinder diesels in the X3 and Q5, and the gearbox does like to ensure it holds a low gear for safety when heading downhill, with the resultant intrusion making us wish a little more sound insulation was used.
