This video is about one of the Group B rally monster: the Lancia Delta S4. This car has a 4 cylinder supercharged and turbo engine which can reach a power of 500+ hp and it can accelerate from 0 to 100 km/h (0-60mph) in just 2.7 seconds on gravel. The S4s can reach the limited top speed, 190 km/h (118 mph), in just 8 seconds. Lancia built 200 road-going S4s, called Delta S4 Stradale, but with less power (250 hp).

In this video you can see three of them during a little race event at Monza Circuit. You can hear the magnificent sound of this rally car and also a lot of flames exiting from the exhausts (THE BIGGEST ONE AT 0:44).
