Progress in the automotive industry is so rapid that you might think automakers come up with new engines all the time.In fact, although they are updated very often, many engines continue in their original basic form years and sometimes decades after the cars they first appeared in went out of production. What follows are the more spectacular examples:Opel CIH: 1965-1995 (30 years)The Opel CIH from General Motors’ (GM) European arm was a highly flexible series of engines that featured four or six cylinders, with sizes ranging from 1.5 liters up to 3.6 liters. The most well-known cars fitted with Opel’s Cam In Head engine were the Ascona, Kadett and Manta (pictured).The CIH actually made its debut in the second-generation Rekord, and was still being used in 1995 in the Isuzu MU SUV, sold in the UK as the Vauxhall Frontera.USED IN: CHEVROLET: 1700, DAEWOO: Royale, HOLDEN: Sunbird, Torana, ISUZU: MU, OPEL: Ascona, GT, Kadett (pictured), Manta, Olympia, Omega, Rekord, Ranger, Saehan Rekord, VAUXHALL: Carlton, Cavalier, Frontera.Rover V8: 1967-2004 (37 years)This all-aluminum engine was based on the Buick 215 (born in 1960), used in both Buicks and Pontiacs. General Motors abandoned it for reasons of expense and unreliability, then sold it to Rover, which redesigned it and made it much more dependable.With an excellent combination of power, torque and light weight, it featured in Rovers (like the SD1 3500, pictured), Land Rovers, MGs, Morgans and TVRs. Starting life as a 3.5-liter, it ended its days as a 4.6-liter, as fitted to the Range Rover.EXCLUDING ITS GM DAYS, IT WAS USED IN: GINETTA: G33, LAND ROVER: Series II, 110/130, Defender, Discovery, Range Rover (pictured), LEYLAND: P76, MGB: GT V8, MG: RV8, MORGAN: Plus 8, ROVER: P5, P6, SD1, TRIUMPH: TR8.

In 4.0-liter form it was one of the best features of the first Jeep Cherokee (pictured) officially imported to the UK, and was still being fitted to the Wrangler as late as 2006.USED IN:AMC: Concord, Eagle, Gremlin, Hornet, Javelin, Matador, Pacer, Rebel, Spirit, JEEP: CJ, Cherokee, Comanche, Commando, Gladiator, Grand Cherokee, Wrangler (pictured), Wagoneer, PARS KHODRO: Arya, Shahin, RAMBLER: Ambassador, American, Marlin, Rebel, Typhoon, RENAULT: Rambler.Citroën 2CV: 1948-1990 (42 years)Citroën’s air-cooled two-cylinder, ranging in size from 375cc to 602cc, lasted the entire life of the 2CV, which might have begun nine years earlier if war hadn’t got in the way.The engine was also used in the Ami, Dyane and Mehari. A 652cc development of it later appeared in the Visa.USED IN:CITROËN: 2CV (pictured), Acadiane, Ami, Bijou, Dyane, Mehari.Ferrari Colombo V12: 1947-1989 (42 years)Shortly after World War 2, Enzo Ferrari (pictured centre) asked engineer Gioacchino Colombo what he would do with a 1500cc engine. Colombo replied that “Maserati has four cylinders, the British have six, Alfa Romeo has eight, so we should have 12.”Enzo entirely agreed, and Colombo’s resulting brilliant V12 was at the heart of a great many 20th-century Ferraris.It appeared in the very first Ferrari-badged car, the 1.5-liter 125 S sports racer, and stayed around (after decades of development and an increase in size to 4.9-liters) until production of the 412 grand tourer came to an end in 1989.USED IN:FERRARI: 125 S, 250 (pictured), 275, 330, 365, 400, 412, Daytona, Superamerica.Jaguar XK: 1949-1992 (43 years)The six-cylinder XK became available to the public when the XK120 (pictured) went into full-scale production in 1950, and for two decades after that it was the only engine fitted to any Jaguar. Born as a 3.4-liter, it went as small as a 2.4-liter and as large as 4.2 liters.Its swansong was its appearance in the Daimler DS420 limousine (pictured).USED IN:DAIMLER: DS420, Sovereign, JAGUAR: 240, 3.4-liter, 420, S-Type (1960s), E-Type, Mark 2, Mark 7, Mark 8, XJ6, XK120, XK140, XK150, XK SS, PANTHER: De Ville, Panther J72.Renault Cléon-Fonte: 1962-2004 (42 years)Named after a factory in Normandy and the French word for cast iron, the Cléon-Fonte appeared in 1962 in the Caravelle sports car (as an 845cc), the Estafette van and the 8 sedan (pictured), the latter being the first vehicle specifically designed to use it.Its last appearance was in a Dacia, by which time it had been enlarged to as much as 1.6 liters.USED IN:ALPINE: A110, DACIA: 1100, 1300/1310, DAF: 55, 66, RENAULT: 4, 5 (sold as Le Car in USA, pictured), 6, 7, 8, 9, 10, 11, 12, 15, 18, 19, Caravelle, Estafette, Fuego, Twingo, VOLVO: 343/345, 66.Alfa Romeo Twin Cam: 1954-1997 (43 years)This twin overhead-camshaft engine was used for more than four decades in front-engined, rear-wheel drive Alfas, from the 1.3-liter Giulietta (pictured) to the 164 eight-valve 2.0-liter Twin Spark which went out of production in 1997.The 16-valve Twin Sparks were based on a later engine designed by Fiat.USED IN:ALFA ROMEO: 155, 164 (pictured), 1750, 1750 Berlina, 2000, 2000 Berlina, 75, 90, Alfetta, Giulia, Giulietta, Gran Sport Quattroruote, GTA, GTV, Romeo, Spider (1966-1994).Ford Kent: 1959-2002 (43 years)The Kent name is used for an engine which first appeared in the British Ford Anglia (pictured - a model today most famous for its appearances in the Harry Potter movies); it was updated with a crossflow cylinder head in 1967.Later versions for front-wheel drive cars are known as Valencia.

Last placed in the Ford Explorer in 2001, it’s no longer used for any production car, but Ford will still sell you a new ‘crate’ engine to do with as you will.The Windsor began life as a 3.6-liter, but got as large as 5.8 liters in the ‘351W’.
