The 155 Q4 is an all-wheel drive sports saloon that replaced the Alfa Romeo Milano Quadrifoglio Verde. It brought along various technologies from the Lancia Delta HF Integrale Evo such as turbocharging and an all-wheel drive system.
The 155 Q4 is powered by a 2 litre turbocharged engine as opposed to the larger naturally aspirated 3.2 litre V6 engine from its predecessor. Both models feature very similar power outputs, although the 155 Q4 has a higher torque rating of 219 ft·lb (297 N·m).
As the 155 model series is based on Fiat's Type Three front-wheel drive platform, the 155 Q4 has a front weight load of 61%, losing to the Milano QV's almost neutral weight distribution. However, the all-wheel drive system allows the 155 Q4 to accelerate much faster and superior grip on unpaved roads than its predecessor.
