Early F1 cars featured front-mounted engines, no wings, and demanded significant driver effort for control. Lighter aluminium chassis appeared in the early 1960s, and wings were added toward the end of that decade. During the 1970s, nose boxes and air boxes were introduced to manage airflow, while the 1980s brought ground effect cars that generated substantial downforce with a small drag penalty, alongside turbocharged engines that pushed power outputs to 1,000 kW (1,400 hp) at 12,000 rpm by 1986.
Following the 1994 San Marino Grand Prix, a series of safety-driven regulatory changes reshaped car design. A 10 mm wooden skid block was mandated on the underside to enforce minimum ground clearance, and exclusion zones were added around the wheels. The maximum car width was also reduced from 2,150 mm to 2,000 mm in 1994. Through the 1990s and 2000s, improved electronics, computer-aided design, and restrictions on advanced materials such as titanium and beryllium became defining features of the regulatory landscape.
Subsequent FIA rule cycles banned double diffusers, exhaust duct modifications, sharklets, winglets, and dive planes. The drag reduction system (DRS) was introduced in 2011. Regulations effective from 2022 simplified aerodynamic components to reduce vortices and increase ground effect, with the stated aim of enabling closer racing.
The modern car uses a carbon fibre monocoque lined with Kevlar and fire-resistant materials. The cockpit holds a single seat and a detachable steering wheel; the halo safety device, a series of curved metal bars protecting the driver's head, was added to the cockpit opening from 2018. Minimum weight including the driver is 798 kg when fitted with dry-weather tyres and carrying no fuel. Maximum dimensions are 5.63 m in length, 2 m in width, and 0.9 m in height.
Prior to 1968, cars were painted in standardised national colours — British racing green, Italian rosso corsa, German silver. The FIA opened unrestricted commercial sponsorship in 1968; Team Gunston was the first constructor to enter a sponsored car, doing so at the 1968 South African Grand Prix. Sponsor-driven liveries became the norm, with one-off event liveries — celebrating anniversaries or specific partnerships — becoming more common after McLaren debuted a special livery for the Monaco Grand Prix in 2021.
Engine regulations have evolved considerably. Early cars used 4.5 L naturally aspirated or 1.5 L supercharged units producing up to 317 kW (425 hp). Capacity was progressively reduced, reaching 1,300–1,500 cc rear-mounted configurations by 1961. FIA increased capacity again in 1966, permitting up to 3.0 L atmospheric engines (290–370 kW) or 1.5 L supercharged units (370–670 kW). Turbochargers were banned from 1989, leading to 3.0 L V10 and V12 engines in the 1990s producing up to 730–750 kW (980–1,000 hp). A 2.4 L naturally aspirated V8 formula was introduced for 2006, rpm-limited to 18,000 from 2009.
The current 1.6 L turbo hybrid V6 configuration dates from 2014, with a revised version introduced for 2022 carrying a more powerful kinetic energy recovery system. A maximum of five power units per season is permitted under current regulations; exceeding the allocation incurs grid penalties. Each unit is expected to last at least 2,000 km. The engine is bolted to the cockpit at its front end and to the transmission and rear suspension at its back end.
The fuel is a tightly controlled mixture of unleaded petrol and ethanol. The ethanol content was raised from 5.75% to 10% for 2022; Formula One transitioned to fully sustainable fuels for 2026. Refuelling during races was banned from 2010. Cars carry a maximum of 110 kg of fuel, stored in a Kevlar-lined rubber bladder situated in front of the engine, behind the cockpit. A minimum of 1 kg must be made available to the FIA for post-race inspection; failure to provide it results in disqualification.
The steering wheel is a carbon fibre and titanium electronic control interface weighing approximately 1.3 kg and costing around $50,000. It carries an LCD screen, LED gear-shift lights, two driver handles, and an array of buttons and paddles to govern gears, engine revolutions, fuel–air mix, brake balance, differential mapping, radio access, and the drinking mechanism.
Modern cars use eight-speed semi-automatic sequential gearboxes with rear-wheel drive. Gear shifts are initiated via paddles on the back of the steering wheel and executed by solenoids and hydraulic actuators in 2–3 ms. The gearbox is constructed of carbon-reinforced titanium and bolted to the back of the engine. Gearbox ratios are fixed for an entire season. Fully automatic gearboxes, traction control, and launch control are prohibited. The clutch is a multi-plate carbon design with a diameter under 100 mm and weight under 1 kg, rated to handle up to 540 kW (720 hp).
F1 tyres evolved from treaded road-car-style rubber in the 1950s through nylon-reinforced and synthetic-rubber constructions in the 1960s. Slick tyres were introduced for the first time in 1971. Grooved tyres replaced them between 1998 and 2008 — with a minimum of four 14 mm grooves required — before slicks were reintroduced for 2009. Front tyre width was narrowed at that point from 270 mm to 245 mm to shift balance toward mechanical grip. For 2017, significantly wider Pirelli tyres were introduced at both axles. The 2022 regulations increased wheel rim diameter from 13 to 18 inches, with overall tyre diameter rising from 670 to 720 mm.
Teams receive a fixed allocation of three dry-weather slick compounds per race weekend, distinguished by colour coding, and must use at least two of them during a dry race. Grooved intermediate and wet-weather tyres are also provided.
Carbon composite disc brakes decelerate the car from 100 to 0 km/h in under 15 m, reaching temperatures of up to 1,000 °C (1,830 °F). Each caliper carries six piston clamp pads. Rear braking combines friction on the discs, engine resistance, and energy recovery system regeneration. Brake cooling is achieved through air ducted through numerous small holes in the brake ducts.
Aerodynamics is central to performance. The sculpted front and rear wings — functioning as inverted aerofoils — along with vanes under the nose, sidepods, underbody, and the rear diffuser collectively determine aerodynamic efficiency. A modern car develops downforce equivalent to twice its weight at 190 km/h and up to six G of lateral cornering force. Car configuration — specifically the balance between drag and downforce — is adjusted to the requirements of each circuit.
The front wing is a forked structure up to 1,800 mm wide, carrying a maximum of four wing elements. It can cost up to $300,000. The wing directs airflow to the sidepod intakes for engine cooling and beneath the floor to create a low-pressure ground-effect seal. Minor changes to the front wing can produce large downstream aerodynamic effects.
The rear wing deflects air downwards through its main plane and horizontal flaps; vertical end plates sit at the wing tips. The DRS, introduced in 2011, allows the driver to open a slot in the rear wing hydraulically to reduce drag and increase straight-line speed in designated zones. The diffuser at the rear combines pressurized underfloor airflow to generate additional downforce. The air box behind the cockpit supplies pressurized air to the engine intakes and absorbs turbulence generated by airflow over the driver's helmet.
The 1.6 L V6 hybrid system produces 710 kW (950 bhp) at 15,000 rpm. A modern car accelerates from 0 to 97 km/h (60 mph) in 1.8 seconds and from 0 to 161 km/h (100 mph) in 2.6 seconds. The power-to-weight ratio of 1,297 hp/t would theoretically allow a 0–100 km/h sprint in under one second; traction limits the actual figure at low speed. Drivers experience 3–4 g during acceleration, 5–6 g under braking from high speed, and 4–6.5 g of lateral force through high-speed corners.
The official FIA-recognised top speed record for an F1 car is 372.6 km/h (231.5 mph), recorded by McLaren during 2005 testing. In racing conditions, Valtteri Bottas reached 372.54 km/h (231.49 mph) in a Williams at the 2016 Mexican Grand Prix. An unofficial one-way record of 413 km/h (257 mph) was set by a modified BAR Honda at Bonneville Speedway on 6 November 2005; a ratified FIA record of 400 km/h (250 mph) was set at the same venue on 21 July 2006.
