Lotus Ford Cosworth 49

As Formula 1 engine capacity rules changed from 1.5 liters to 3 liters (or 1.5 liters compressed) for the 1966-1986 seasons, a few manufacturers were left scrambling for suitable power plants.

For 1966, Lotus raced their 33 with both a Climax V8 and BRM V8 and H16 engines, with poor results. They also raced their model 43 BRM to one win.

In the background, Lotus Team owner Colin Chapman was busy convincing the Ford Motor Company to finance the design and build of a new 3 liter V8. Cosworth Engineering Ltd, a successful racing engineering company created by Mike Costin and Frank Duckworth, was commissioned to undertake the new design.

As in their model 43, Lotus wanted to design the chassis with the engine as a load-bearing structure carrying the rear suspension. Colin Chapman and fellow designer Maurice Phillipe worked very closely in parallel with Cosworth to assure the success of this approach.

The new Ford Cosworth DFV V8 was introduced in late April 1967, and the Lotus/Cosworth engineering worked hard to have the engine/chassis package ready for it race introduction at the Dutch Grand Prix held at Zandvoort on June 4.

Lotus driver Graham Hill easily won pole position, with fellow driver Jim Clark started in 8th place on the grid. As the race started, Hill quickly pulled away from the pack, holding the lead till his engine gave up. In the meantime, Clark moved up through the cars to take on the lead and win the race! An astonishing debut for a new car!

Unfortunately, the engine and chassis were not without their little gremlins, which allowed Denny Hulme racing the Brabham Repco to take the Championship.

For the 1968 season, the de-bugged package did it’s magic, with Graham Hill rallying the team after Jim Clack’s death in an F2 race and taking the Championship for Lotus in the 49B.

Interestingly for 1968, Lotus’ Team no longer carried British racing green, but instead the sponsorship colours of Gold Leaf cigarettes, a step that would change the face of Formula 1 sponsorship, and the car’s colours …

1962 Targa Florio

The 1962 Targa Florio, the 46th edition of the famous sports/GT race, ran on 72 kms of perilous public roads through Sicily on May 6.

In the preceding years, it seemed to be a battle between the Porsches and the Ferraris.

For 1962, Scuderia Ferrari raced their Dino 246 SP (No.152), driven by Willy Mairesse, Olivier Gendebien and Ricardo Rodriguez, and their Dino 196 SP (No.120), raced Giancarlo Baghetti and Lorenzo Bandini.

Ferrari No.152 finished the 10 laps in first place, taking it in 7hrs2mins56secs, followed by No.120 12 minutes later in second place.

Scuderia Ferrari would have to wait till 1965 to get those winner’s laurels back.

Sunoco Porsche 917-30

Can-Am racing was basically McLaren’s game in the late sixties/early nineteen-seventies.

In Europe, Porsche’s successful 917 was regulated out of competition for 1972, so their attention turned to the highly popular and lucrative Can-Am series as a way of repurposing the 917 in the North American market.

For 1972, the 917-10 was developed, featuring a completely new Spyder body. Roger Penske’s Team Penske ran the team with primary driver Mark Donohue.

Early in the season, Donohue was side-lined for most the season in a testing accident, so George Follmer was recruited to take his place. Follmer dominated the season by taking five wins out of nine races.

For 1973, Team Penske was given carte-blanche by Porsche to modify and improve the 917-10. Penske and Donohue revised the aerodynamics, lengthened the wheelbase and tweaked the engine, bringing the power up to a monstrous 1580 horsepower!

The new car was designated the 917-30, and was presented in lovely Sunoco yellow and blue sponsorship colours.

Marc Donohue won six out of the season’s eight races in the new racer and took the 1973 Can-Am Championship for Team Penske.

New rules for the 1974 season basically outlawed the 917-30, but it still stirs the blood of those lucky enough to see it in action at the vintage racing meets.
