The huge gap in speed between the cars at the front and back of the Formula One grid is ruining the sport, says Max Chilton.

Chilton raced in F1 with back-markers Marussia for two years in 2014 and 2015 and now drives in the US in the IndyCar series.

The 26-year-old claims IndyCar offers closer and more exciting racing than its more glamorous counterpart, and until there is a closer playing field in F1 the entertainment value will be lacking.

Speaking to Sportsmail, Chilton said: 'The problem Formula One has got at the moment is there is a four-second gap between the lead car and the back car and that's not really sport. Sport should pretty much be a level playing field or as close to possible.

'Motorsport is never going to be like that, it's impossible, but IndyCar next year is going to be as near a one-make series than they have done. Everyone has the same aero kit and there is very little difference between the engines and the racing should be even closer next year.

Chilton also feels the drivers in IndyCar enjoy a better quality of life between each event than those who travel the world for F1.

Unlike F1, which has 21 races in different countries all over the world, IndyCar is based exclusively in the US, something which Chilton feels is a benefit.

'In America we sometimes race in very desolate parts and everyone has their motorhomes. There's a great camaraderie between the drivers, we all get on really well and we get more time to socialise together so there's more friendship.

'The problem with F1 is it is so intense and so much travelling involved from country to country there is less time to really enjoy it.'

After racing in 35 F1 Grand Prix without scoring a point, Chilton joined Chip Ganassi Racing in 2016 and has raced 33 times. He will join debut team Carlin for the 2018 campaign.
