The main types of race cars are open-wheel cars (Formula One, IndyCar), sports and endurance cars (Le Mans prototypes and GT cars), touring cars, stock cars (NASCAR), drag racers, off-road trucks and karts. Each is built for a specific track, rule book and kind of racing, so a car that wins in one series would usually be uncompetitive in another.
Types of race cars at a glance
| Type | Typical series | What defines it |
|---|---|---|
| Open-wheel | Formula One, IndyCar | Single-seaters with exposed wheels, light chassis and heavy use of aerodynamics |
| Sports car / endurance | 24 Hours of Le Mans, FIA World Endurance Championship | Prototypes and production-based GT cars built to last long races, often with shared drivers |
| Touring car | British Touring Car Championship, DTM | Production-derived four-seat cars adapted for closed circuits, with close racing |
| Stock car | NASCAR Cup Series | Heavily modified production-style cars, mostly raced on ovals |
| Drag car | NHRA classes such as Top Fuel and Funny Car | Built purely for straight-line acceleration over a short strip |
| Off-road | Baja 1000 | Reinforced chassis, long-travel suspension and rugged tyres |
| Kart | Junior and club karting | Simple, light and cheap, and a common starting point for drivers |
How race cars differ from road cars
A road car must be comfortable, quiet, efficient and safe for ordinary drivers. A race car is built for lap time within a rule book, so almost every choice is aimed at grip, power, weight or durability.
- Safety equipment: race cars use stronger structures, multi-point harnesses and fire-resistant gear, and drivers wear helmets and head-and-neck restraints such as the HANS device.
- Aerodynamics: wings, splitters and diffusers push the car onto the track, which improves cornering but adds drag.
- Tyres: compounds and pressures are chosen for the track, temperature and race length.
- Comfort: sound deadening, trim and luggage space are usually removed to save weight.
What race teams adjust in a setup
Teams tune a car for each circuit and set of conditions. The most common levers are:
- Aero balance: steeper wing angles add downforce for tight corners; flatter ones cut drag for long straights.
- Suspension: ride height, spring and damper settings and anti-roll bars change how the car handles bumps and weight transfer.
- Alignment: camber and toe settings keep the tyre’s contact patch working and affect tyre wear.
- Tyre pressure: lower pressure can add grip but raises heat and wear; higher pressure does the opposite.
Teams use data from practice sessions to see whether a change helped lap time and driver confidence, then make small adjustments rather than big ones.

Frequently Asked Questions
What are the main types of race cars?
The main types are open-wheel cars, sports and endurance cars, touring cars, stock cars, drag cars, off-road racers and karts. Each is designed around a series’ rules and track type.
What is an open-wheel race car?
An open-wheel car has its wheels outside the main body. Formula One and IndyCar are the best-known examples, and they rely heavily on aerodynamics for grip.
What is the difference between stock car and touring car racing?
Stock cars, such as those in NASCAR, are heavily modified production-style cars raced mostly on ovals. Touring cars are production-derived cars adapted for closed road circuits.
How are race cars different from road cars?
Race cars are built for lap time and durability within a rule book. They have stronger safety structures, harnesses, aerodynamic parts and little or no comfort equipment.
What do teams change in a race car setup?
The usual adjustments are wing angles, ride height, springs and dampers, anti-roll bars, camber and toe, and tyre pressures, based on practice data.
Where can I read about specific race cars?
