Prepare for a brief rally history lesson with the original Lancia Stratos and the Lancia Delta S4. Chris Harris gets a chance to ride shotgun in two of the all time greatest rally cars. The drivers making magic with the Stratos and the Delta S4 during the launch event of the Pirelli P7 Corsa Classic are rally legends Markku Alen and Juha Kankkunen. The Lancia Stratos was the first car ever to be designed specifically for rally racing. The Lancia Delta S4 competed in the 1985 and 1986 WRC championship in Group B, until FIA banned it. Why? Let's just say it had almost 5 bars of boost and it was developing around 1,000 hp.
