F1 in America: The Grand Prix stars who tamed the Brickyard – and how F1 changed the Indy 500 forever

The 107th running of the famed Indianapolis 500 takes place this coming Sunday. Thirty three identical Dallara IR18s, powered either by Chevrolet or Honda engines, will compete for the victory over 200 laps.

To the casual observer they don’t look all that different to F1 cars. The mandatory Dallara chassis weighs in around 748 kg in Indy 500 trim and is powered by a 2.2-litre V6 turbocharged engine. Their F1 brethren are slightly lighter at 733 kg and produce 1000 to 1100 bhp from their 1.6-litre turbo-hybrid motors, which are supplied by Mercedes, Ferrari, Honda or Renault/Alpine.
