Here's all you need to know about the differences between the two premier single-seater championships - F1 and IndyCar
Formula 1
Aero regulations are restricted by height, width and location boundaries. But within this small box of possibilities, teams are free to do what they like. Downforce is constantly being searched for, to make the cars quicker and also easier to drive. Semi-automatic, seamless shift gearboxes comprise of eight forward gears (with ratios selected prior to the season) and a reverse. Each gearbox must last six consecutive events.
The steering wheels
are very complicated with a considerable number of buttons, dials,
thumb wheels, paddles and combinations, as well as a screen display for
viewing information and data. Carbonfibre composite brake discs squeezed
by a conventional hydraulic calliper are used, helping power the ERS
system. Tyres are supplied by Pirelli, with five slick compounds in
2016, an intermediate and an weather compound. See more on the new tyre
rules here.
Pit stops are mandatory during races and the Drag Reduction System (DRS) is used as an overtaking aid in the series. Performance stats vary depending on the car, but the highest speed recorded in 2015 was by Lewis Hamilton in Mexico FP1, clocking 223mph (360km/h). Cars weigh 702kg and the championship-winning Mercedes W06 measures 5000mm long, 1800mm wide and 950mm high.

Unlike F1, IndyCar runs the same chassis and with two engine manufacturers – Honda and Chevrolet. But while the actual cars are the same, the aero kits are unique depending on the engine supplier. The 2016 calendar will feature 15 rounds and 16 races, due to the double-header in Detroit, with typically a 24-car grid. However, this is increased to 34 cars for the famous Indy 500.
The aero kits – introduced in 2015 - for the two engine
suppliers have to fit into “legality boxes” and only two can be used
during a season (with the standard Dallara one being an option).
Development areas include sidepods, engine cover, rear wheel guards,
front and rear wing main planes and endplates and Indy 500 rear wing
main planes. Meanwhile some components are standard like the nose,
mirror housing and roll hoop fairing. Kits are different for small
ovals, street and road courses compared to speedways.
Like F1, IndyCar has an overtaking aid – the push-to-pass system. A button on the steering wheel enables drivers to get a boost of speed. They get 10 pushes per race, with the time varying between 15 and 20 seconds. The steering wheels also feature a wide array of buttons and a dash containing information. Refuelling is allowed in IndyCar and pitting is mandatory, with each one lasting between six and 10 seconds. In F1 there is no refuelling and this makes stops a fair bit quicker.
IndyCar and F1 cars are very different beasts, with different priorities. They are both open-wheel racers but have varying performance figures. While IndyCar races on a wider range of tracks and changes specifications depending on the venue, F1 is much more standardised, but there is more innovation due to the individual teams creating the cars – although there is now more diversity in IndyCar.
