Pagani’s 220mph Zonda S is to get even faster with a host of wide-ranging updates for 2005. The 555bhp Zonda S is to be superseded by the lighter, 620bhp Zonda R. Fitted with new intake and exhaust systems and a modified ECU, and with an estimated 50kg shaved off its kerbweight, the AMG-powered Zonda’s power-to-weight ratio will jump to more than 500bhp-per-tonne. It should be more than a match for the 484bhp-per-tonne Ferrari Enzo. These pictures show that the new Zonda will retain its elegant curves, but adopt race-car looks. A wider single-piece rear spoiler helps increase downforce by 40 per cent. Larger 19- and 20in alloys wheels hide bigger 385mm Brembo discs. Carbon-ceramic discs will be optional. The R should have a similar price to the current car – around £285k. It will appear at March’s Geneva Motor Show.
