Alonso’s McLaren-Honda-Andretti racer will have a Dallara DW12 chassis – as per the race’s regulations – and be powered by a Honda 2.2-litre twin-turbocharged V6 engine. It’s limited to 12,000rpm and is capable of producing about 700bhp.
The McLaren entry marks the British team’s return to America’s iconic endurance race after a 38-year absence. It won the race in 1974 and 1976 (pictured below).
The IndyCar event will be Alonso’s first Indy 500, so he will race as a rookie.
“I’ve never raced an IndyCar car before, and neither have I ever driven on a super-speedway, but I’m confident that I’ll get to grips with it fast,” said Alonso. “I’ve watched a lot of IndyCar action on TV and online, and it’s clear that great precision is required to race in close proximity with other cars on the far side of 220mph."
