What kind of car races in the indy 500

This takes about four hours to do. Also, Nascar has many more races during each season. Nascar has somewhere around 36 races while F1 has around The winner of a Formula 1 season is the driver with the most points. Nascar has a championship race that consists of 16 drivers. The winner is determined after those races. Formula 1 tracks have all kinds of twists and turns, which arguably make it more interesting.

These tracks usually mean less than laps on a track which takes under two hours. While racing in Nascar, the cars tend to bump and touch a lot as the cars go around the track. F1 cars are not allowed to touch at all. Getty Images.

The Indy is one of the most prestigious automobile races in the world. It dates from , is rife with tradition, and is one of the most action-packed live events you can watch, whether you're an auto-racing novice or a hardened fan. Thirty-three drivers will take the green flag on Sunday, May 26, for the rd running of the race and compete at speeds of more than mph for miles on Indy's 2.

At the moment the 10 F1 teams are supplied by four different power unit manufacturers: Mercedes , Honda , Renault , and Ferrari - although Honda is leaving at the end of the season, with Red Bull set to take over the project.

Development of the power units is being frozen for ahead of a yet-to-be-revealed new formula for The gearbox comprises eight forward gears with a fixed ratio across the whole season and a mandatory reverse. Aerodynamic regulations across the different areas of the car are tightly restricted by height, width and location boundaries. But within these small boxes of possibilities, teams are more or less free to do what they like.

All that complex aero creates a lot of aerodynamic wash, or dirty air, which makes it difficult for the cars to follow one another closely at high speed. When a driver is within one second of the car in front, they can press a button that opens a slot in the rear wing, allowing it to travel faster in a straight line and making it easier to overtake. The total weight of the cars is mandated to be a minimum of kg, a hefty increase from the kg cars of little more than a decade ago.

The steering wheels are very complicated with a considerable number of buttons, dials, thumb wheels, paddles and combinations which are used to adjust things such as brake balance, differential settings, and engine modes, as well as a screen display for viewing information and data. Carbonfibre composite brake discs squeezed by a conventional hydraulic caliper are used with the rear ones assisted by the ERS.

Tyres are supplied by Pirelli, with five dry-weather compounds available across the season, three of which are available to use at any given race, depending on the circuit characteristics. Pit stops are mandatory during races thanks to the need to use two different dry compounds of tyre in a race. Unlike F1, the IndyCar grid runs the same chassis and aerodynamic kit, with power coming from one of two engine manufacturers - Honda or Chevrolet.

Grid sizes are a bit more fluid than in F1, with most races featuring 24 or 25 drivers, which balloons up to a field of 33 for the blue riband event that is the Indianapolis Separating the F1 chassis from the other two forms of racing is the fact that the team is responsible for designing and building the car from the ground up. Both F1 and IndyCar are equipped with a push-to-pass system, an engageable system that gives the car a quick boost of speed, which can be used ten times per race.

Looking beyond the vehicles, there are some clear differences in the way the races unfold, as well. In terms of length, the shortest of the three is the Formula One, which can take less than two hours to complete. Speaking on race times, F1 races are generally timed and end after 2 hours regardless of how many laps have been completed while NASCAR races go until the checkered flag flies on the final lap.
