This week on the Car and Bike Show, we take you to the 4.18 kms long Estoril track, where Siddharth drives the all new BMW M5. The sixth generation BMW M5 is the first of the 'M' badged sedans to get 4x4 and manages to look menacing enough with the subtle M add-ons. Post the review, awaits highlights from the L.A. Auto Show, were Cyrus introduces us to all new exciting cars from the show.
