The Chevrolet Bel Air was a full-size automobile that was produced by the Chevrolet division of General Motors for the 1950–1975 model years. Hardtops in the Chevrolet Deluxe Styleline model range were designated with the Bel Air name from 1950 to 1952, but it was not a distinct series of its own until the 1953 model year. Bel Air production continued in Canada for its home market only through the 1981 model year.In 2002, a concept Bel Air convertible was shown at the North American International Auto Show. It features a few styling and design cues from the legendary 1955–57 models, such as the chrome windshield frame, traffic light viewfinder, and a gas filler cap behind the tail light, similar to 1956–1957 Chevy's gas cap behind the chrome trim on the back of the tail fin, but more like the 1948–1958 Cadillac gas cap light. It also features the same a body on frame hydroforming technology (used in the frame rails of the Corvette and GM’s midsize sport-utility vehicles) and a sheet metal body, on a 111 in (2,800 mm) wheelbase, and a 65 in (1,700 mm) track. Suspension is short long arm up front and Hotchkiss drive in the rear. It rides on five-spoke aluminum wheels with 18 in (46 cm) red line tires and anti lock discs all-round. The elegant, yet simple interior features a twin-element instrument panel, column-mounted gearshift and bench seats covered in soft high-tech fabrics colored red to match the exterior that are cleverly designed to slide forward for easier backseat entry. It also served as a showcase for the their new turbocharged inline five-cylinder concept engine based on the L52 (Vortec 3500), straight-5 truck engine. According to a September 2002 GM press release, the all-aluminum 3.5 L (211 cu in) 20-valve DOHC engine, with a bore of 93.0 mm (3.7 in), and a stroke of 102.0 mm (4 in), that delivers up to 315 horsepower and 315 lb·ft (427 N·m) of torque, mated to a Hydra-Matic 4L60-E electronically controlled four-speed automatic. A virtual "turbo boost" button on the steering wheel activates the powertrain control module to trigger a more aggressive spark and fueling calibration for maximum horsepower. It also led the 13th Annual Stater Brothers Route 66 Rendezvous as the official vehicle in September 2002. General Motors has shown no interest in producing the car.
