The hood (American English) or bonnet (Commonwealth English) is the hinged cover over the engine of motor vehicles. Hoods can open to allow access to the engine compartment, or trunk (boot in Commonwealth English) on rear-engine and some mid-engine vehicles) for maintenance and repair.
In British terminology, hood refers to a fabric cover over the passenger compartment of the car (known as the 'roof' or 'top' in the US). In many motor vehicles built in the 1930s and 1940s, the resemblance to an actual hood or bonnet is clear when open and viewed head-on. In modern vehicles it continues to serve the same purpose but no longer resembles a head covering.
On front-engined cars, the hood may be hinged at either the front or the rear edge, or in earlier models (e.g. the Ford Model T) it may be split into two sections, one each side, each hinged along the centre line. Another variant combines the bonnet and wheelarches into one section which allows the entire front bodywork to tilt forwards around a pivot near the front of the vehicle (e.g. that of the Triumph Herald). [1]
Hoods are typically made of the same material as the rest of the body work. This may include steel, aluminum, fiberglass or carbon fiber. Some aftermarket companies produce replacements for steel hoods in fiberglass or carbon fiber to reduce vehicle weight.
The hood release system is common on most vehicles and usually consists of an interior hood latch handle, hood release cable and hood latch assembly. The hood latch handle is usually located below the steering wheel, beside the driver's seat or set into the door frame. On race cars or cars with aftermarket hoods (that do not use the factory latch system) the hood may be held down by hood pins. Some aftermarket hoods that have a latch system are still equipped with hood pins to hold the hood buttoned down if the latch fails.
A hood may contain a hood ornament, hood scoop, and/or wiper jets. A portion of the hood may be raised in a power bulge, to fit a large engine or air filters.
In Japan and Europe, regulations have come into effect that place a limit on the severity of pedestrian head injury when struck by a motor vehicle. [2] This is leading to more advanced hood designs, as evidenced by multicone hood inner panel designs as found on the Mazda RX-8 and other vehicles. Other changes are being made to use the hood as an active structure and push its surface several centimeters away from the hard motor components during a pedestrian crash. This may be achieved by mechanical (spring force) or pyrotechnic devices.[ citation needed ]
The Saab Sonett is an automobile manufactured between 1955 and 1957 and again between 1966 and 1974 by Saab of Sweden. Sonetts share engines and other components with Saab 93, 95 and 96 of the same era. It was mainly intended for the lucrative American export market and was only offered intermittently in the Swedish domestic market.
A cold air intake (CAI) is usually an aftermarket assembly of parts used to bring relatively cool air into a car's internal-combustion engine.
The Shelby Mustang is a high-performance variant of the Ford Mustang built by Shelby American from 1965 to 1967 and by the Ford Motor Company from 1968 to 1970.
An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of:
The trunk or boot of a car is the vehicle's main storage or cargo compartment, often a hatch at the rear of the vehicle. It can also be called a tailgate.
A latch or catch is a type of mechanical fastener that joins two objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.
A glossary of terms relating to automotive design.
A subframe is a structural component of a vehicle, such as an automobile or an aircraft, that uses a discrete, separate structure within a larger body-on-frame or unit body to carry certain components, such as the engine, drivetrain, or suspension. The subframe is bolted and/or welded to the vehicle. When bolted, it is sometimes equipped with rubber bushings or springs to dampen vibration.
A body kit or bodykit is a set of modified body parts or additional components that install on a stock car. Typically composed of front and rear bumpers, side skirts, spoilers, bonnets, and sometimes front and rear side guards and roof scoops. There are many companies that offer alternatives to the original factory appearance of the vehicle. Body kit components are designed to complement each other and work together as a complete design. Despite this, the 'mix and match' approach is often seen on cars, where the front of one body kit will be matched with the rear of another, for example.
The Chevrolet Corvette (C6) is the sixth generation of the Corvette sports car that was produced by Chevrolet division of General Motors for the 2005 to 2013 model years. It is the first Corvette with exposed headlamps since the 1962 model. Production variants include the Z06, ZR1, Grand Sport, and 427 Convertible. Racing variants include the C6.R, an American Le Mans Series GT1 championship and 24 Hours of Le Mans GTE-Pro winner.
A quarter panel is the body panel of an automobile between a rear door and the trunk (boot) and typically wraps around the wheel well. The similar front section between the door and the hood (bonnet) is called a fender, and may sometimes also be referred to as a quarter panel. Quarter panels are typically made of sheet metal, but are sometimes made of fiberglass, carbon fiber, or fiber-reinforced plastic.

Sylva Autokits is a kit car manufacturer based in Lincolnshire, England. Sylva was founded in 1981 by Jeremy Phillips and has developed and produced a number of small and lightweight sports cars. Sylva cars have won a number of 750 Motor Club Kit Car championships.
A continental tire or a continental kit is a term used in the United States for an upright externally-mounted spare tire located behind an automobile's trunk, made popular by the Continental Mark Series, which carried a simulated continental tire until 1998.
A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting a vehicle. Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle.
A hood scoop or bonnet scoop, sometimes called bonnet airdam and air dam, is an upraised component on the hood of a motor vehicle that either allows a flow of air to directly enter the engine compartment or appears to do so. It has only one opening and is closed on all other sides. Its main function is to allow a direct flow of air to the engine, hence the need for it to be an upraised component to effectively channel air to the engine compartment. It may be purely decorative when its closed, or serve to enhance performance in several possible ways.
The Blakely Bantam was a kit car produced by Blakely Auto Works, a manufacturer of kit cars located in a series of US midwest communities in the 1970s and 1980s. Blakely Auto was founded by Dick Blakely to market affordable sports cars in the spirit of the legendary Lotus Seven: compact, lightweight, and with excellent handling. The Bantam's design inspiration was the Dutton, a Lotus Seven replica built in Britain. The Bantam was introduced in 1972 as Blakely's first offering, followed by the larger Bearcat and eventually by the Bernardi. Production of the Bantam continued into the 1980s, when the model was renamed the Hawk, and stopped with the dissolution of Bernardi Auto Works in the later 1980s.
The Ford Fairlane Thunderbolt is a limited production, factory experimental, drag racing version of the Ford Fairlane produced during the 1964 model year only. A total of 100 units were produced; forty-nine 4-speeds and fifty-one automatics, enough to secure the 1964 NHRA Super Stock championship for Ford.
The sixth-generation Chevrolet Camaro is an American pony car. Produced by automobile manufacturer Chevrolet, it was first introduced to the public on May 16, 2015. Sales started in 2015 for the 2016 model year. The Camaro now utilizes the GM Alpha platform shared with the Cadillac ATS and CTS and features MacPherson struts in front, rather than the former multi-link setup. General Motors claims that 70 percent of architectural components in the new Camaro are unique to the car.
