1964 Porsche 904 Carrera GTS

The Type 904, born of Porsche’s disappointing foray into Formula One in the early 1960s, was produced to bring the company back to its racing sports car roots. In 1962, the immensely talented Ferdinand A. “Butzi” Porsche was tasked with designing a new two-seat competition coupe that could also be […]

1966 Ferrari 275 GTB Competizione

In July 1966, the Ferrari factory received an order from SAVAF for a 275 GTB Competizione, later specified to be chassis 09079. Late in the specialty model’s limited run, the car was the penultimate example of the thinly aluminum-skinned competition GTB, making it the second-to-last GT car ever produced by […]

1934 Talbot AV105 “Alpine Racer”

Simply the best. No other phrase better sums up BGH 23. In its day, this was the outstanding British sports touring car. Georges Roesch’s long line of “Invincible Talbots” needs little introduction to the discerning car connoisseur, and only a combination of poor luck and poor timing meant they never […]

1993 Porsche 911 Type 964 Carrera RSR 3.8-Liter Competition Coupe

Built for privateers to go international GT racing, the phenomenally successful RSR was one of the final developments of the Porsche 911 Type 964, which on its launch in 1989 had represented a major step forward in the development of Porsche’s long-running sports car. Two versions were offered — the […]

1972 McLaren M20 Can-Am

After several years dominating the Can-Am series with a series of school-bus-yellow racers, McLaren Cars stood up to the developing Porsche challenge with the brand-new 1972 M20. Designers Gordon Coppuck and Tyler Alexander departed from standard McLaren practice in the M20 by removing the radiator from the front of the […]

1966 Brabham-Repco BT20 F1 and 1968–69 Lotus-Cosworth Ford Type 49B F1

1966 Brabham-Repco BT20 F1 When the FIA announced in late 1963 that a 3-liter limit would be imposed on Formula One racing in 1966, a scramble ensued among competitors to develop suitable new engines. Jack Brabham turned to Repco, an Australian parts supplier. Development centered on Oldsmobile’s F-85 V8 block, […]

1954 Ferrari 375 MM Plus Competizione

In the winter of 1953–54, Enzo Ferrari concentrated his engineers’ attention upon perfecting a line of large-capacity sports-racing cars for customer sale, backed by a secondary line of smaller variants. To promote and publicize the new sports cars, he approved development of a muscle-bound, outsized “big bazooka” for his Works […]

1964 Alpine M64

In 1955, Alpine was founded by Jean Rédélé, who originally modified and campaigned Renault 4CVs but quickly found success in many of the world’s most illustrious sports car races. Soon enough, Rédélé started building his own cars on the 4CV chassis and mechanicals, with the A106 being produced in 1955. […]

1968 Porsche 907 LH “Longtail”

Today, Porsche remains the uncontested champion of more endurance races than any other manufacturer, having amassed the most outright wins at Le Mans, Daytona and Sebring. Yet in the early 1960s, Porsche remained an unconventional, small-displacement manufacturer only capable of winning class victories. At the onset of the prototype era, […]

1966 Lola T70 Mk II Can-Am Spyder

Lola Cars was founded in 1958 by former Quantity Surveyor Eric Broadley, who was located in Huntingdon, England. His first “production car,” the Lola Mark I, was so superior that it immediately made obsolete Colin Chapman’s previously unbeatable Lotus 11s — as well as all Elvas and Coopers. One of […]
