Lampredi’s twin cam engine was first seen in the Fiat 124 coupé of late 1966, but was later made available in a large number of cars.

Fiat was a pioneer in engine development during the time period, using toothed rubber belt driven camshafts and aluminium alloy heads. Earlier Fiat Twin Cam engines were actually O.S.C.A. designs.

The Fiat Twin Cam (also known as the Lampredi Twin Cam) is an advanced double overhead camshaft inline-four automobile engine produced from 1966 through 2000 as a Fiat/Lancia engine. Designed by ex Ferrari engineer Aurelio Lampredi, the engine was produced in a large number of displacements, ranging from 1.3 to 2.0 L (1,297 to 1,995 cc) and was used in Fiat, Lancia, Alfa Romeo, SEAT, FSO and Morgan cars. The Fiat Twin Cam engine has been widely used in motorsport and has been the most successful engine in the history of the World Rally Championship. Fiat and Lancia won a total of ten World Rally Championships for Manufacturers using engines based on the Lampredi Twin Cam engine. It was replaced by the Fiat «family B» Pratola Serra engine series.

The Fiat Twin Cam engine has been widely used in motorsport and has been the most successful engine in the history of the World Rally Championship. The World Rally Championship for Manufacturers has been won by Fiat and Lancia, using engines based on the Lampredi Twin Cam engine, for a total of 10 years.

The four valve version made its first appearance in the Group 4 competition version of the Fiat 124 Spider Abarth, where it had 1.8 litres. Group 4 regulations at that time allowed the use of a cylinder head of a «free» design. This engine still used a three-piece cylinder head design with an included valve angle of 46 degrees.

In later years motorsport regulations were changed so that the use of four valve heads was only possible when the homologated cars had four valve heads. Therefore, the homologation series of the Fiat 131 Rally Abarth came with a two-litre version of the four valve engine.

These engines were later used in the mid-engined Lancia 037, where they were supercharged and eventually enlarged to 2.1 litres.

In addition to the titles in the World Rally Championship, the Fiat Twin Cam equipped the Lancia Beta Montecarlo turbo, that won the World Sportscar Championship for two consecutive seasons in 1980-1981.

The Fiat Twin Cam has also been used in hot rods and kit cars, with an aftermarket kit to swap one into the Morris Minor.

Our story began in the spring of 1963, when the legendary GM design supremo Bill Mitchell sent a brand new Corvette Sting Ray to Pininfarina, with orders to turn it into a show prototype in time for the Paris motor show in the fall of the same year.

Mitchell was interested in seeing an Italian take on America’s sports car, but little did he know that once that Corvette arrived at Pininfarina, the task of designing a new body for it fell onto another American: Tom Tjaarda from Detroit, Michigan.

The result was the beautiful Corvette Rondine, whose name is the Italian for «swallow» and was inspired by the car’s peculiar rear-end design, reminiscent of the bird’s tail.

The Rondine was shown at the Paris show as planned, and although the GM top brass was happy with the exercise, the Rondine was always meant to remain a one-off. It stayed in Pininfarina’s possession until it was sold to a private collector in 2008.

GM’s loss, Fiat’s gain

However, a few months later, Fiat came knocking at Pininfarina’s door with the express request to adapt the Rondine’s design for a spider derivative of its upcoming 124 family sedan. The result was presented in the fall of 1966 as the 124 Sport Spider, and, much to Tom Tjaarda and Pininfarina’s credit, little of the Rondine’s flair was lost despite the two cars’ very different proportions and the project’s cost limitations.

Under the 124 Sport Spider’s hood sat a 1.4 liters inline-4 twin-cam engine rated at 90 HP at 6500 Rpm, sent to the rear wheels via a five-speed manual transmission.

Derivatives of this unit would power all subsequent versions of the 124 Spider and spawn an entire family of twin-cam engines whose production lasted into the 1990s that are commonly referred to by the name of Fiat’s legendary engine designer Aurelio Lampredi.

The first significant evolution of the model arrived in late 1969 at the Turin motor show, which saw the debut of the 124 Sport Spider 1600, equipped with the 1.6 liters twin-cam engine from the 125 Special and sporting a new egg-crate grille, larger taillights, and the now-iconic twin power bulges on the bonnet.

The 124 Sport Spider then received another performance boost in 1972, thanks to the fitment of the 1.8 liters version of the twin-cam engine from the new Fiat 132 sedan. However, that wasn’t accompanied by any significant change in the model’s exterior appearance.

Fiat’s weapon of choice became the 124 Abarth Rally: a lighter and more powerful homologation special introduced in 1972 whose most important prerogative was the adoption of a completely new rear suspension with McPherson struts in place of the original live axle.

Despite stiff competition, Fiat’s works team managed to win the European Rally Championship twice with the 124 Abarth Rally, first in 1972, then in 1975, the last year before the 131 took over the role of defending Fiat’s honor on the world’s rally stages.

Hero of two worlds

The end of 1975 also marked the 124 Sport Spider’s exit from Fiat’s catalog, at least in the home market.

However, demand for the 124 Spider from the US market remained strong enough for Fiat to maintain the model in production, which meant complying with increasingly stringent Federal environmental and safety legislation.

These later cars are known among Italian enthusiasts as «Spider America,» even though the term was never officially used. They are recognizable at a glance by the raised ride height, side marker lights, and chunky bumpers, all of which did nothing for the car’s look.

Choked by primitive smog equipment and fitted with a single small carburetor and a mild camshaft profile, the federalized 1.8 liters twin-cam engine only produced about 85 HP, and the 2.0 liters that replaced it from 1978 did no better. Things improved in 1981, when the adoption of Bosch L-Jetronic fuel injection brought the engine’s output to a more respectable 105 ponies.

In 1983 Pininfarina offered a limited run of Spidereuropa Volumex, equipped with a supercharged version of the twin-cam 2.0 liters engine rated at 135 HP. This was never made available to US customers, for which a turbo conversion was offered instead, developed by the firm Legend Industries.

Production of the 124 Spider finally ended in 1985.

By then, the model was way beyond its sell-by date anyways, and the demise of the last rear-wheel-drive Fiat sedans meant Pininfarina lost the supply of engines and transmissions from which the Spider’s production depended.
