1966 Porsche 906

This car took part in the AT&T Istel Steigenberger Supersports Cup Race at the Christie's International Historic Festival meeting at Silverstone in July 1992. I took the photograph from inside the paddock of the car on the straight between Priory and Brooklands corners during a practice session.

It's Ivan Scotti's 1966 Porsche 906, a car that was introduced in 1966 to replace the Porsche 904. It took part in Group 4 Sports Car racing and the homologation requirements were that at least 50 examples should be produced. The car was powered by a 1,991cc flat-6 engine, but four cars were produced with a 2,195cc flat-8 engine to run in the Group 6 Sports Prototype Class which didn't have a homologation requirement. The programme of this Silverstone event gives the capacity of Ivan Scotti's car as 2.2 litres, so this appears to be one of the cars with the flat-8 engine.

On 2 May 2017 I showed a photograph of this car that I'd taken at Silverstone in 1996.

Porsche 906

This car competed in the Visage Pre '72 Le Mans Car Race at the Coys International Historic Festival meeting at Silverstone in August 1996.

It's Ivan Scotti's 1966 2-litre Porsche 906, and the programme of the event said this about the 906:

The Porsche 906 was the first product of the company's new Research & Development man, Ferdinand Piëch. A tubular-framed car, also known as the Carrera 6, it was raced to numerous Group 4 successes in the mid-1960s and developed into an equally successful Group 6 racing version, the 910.

I've featured the Porsche 906 twice before, on 24 February 2015 and 26 October 2015.

Lola T70

This car competed in the 1 hour long Historic Motor Racing News Gentlemen Drivers Sports Racing Challenge race at the Gold Cup meeting at Oulton Park in August 2005.

It's the 1965 Lola T70 Mk1 driven in the race by Frank Sytner and Simon Hadfield, and a note in the programme of the event says this about the car:

Debuted, unpainted, by David Hobbs at Goodwood in 1965, chassis SLXX/4 was also raced by Monte Shallet and road registered by a later owner. Reimported from the USA by Frank Sytner in 2003, it is probably the earliest T70 still racing. Chevrolet V8 engine packs a big punch in Eric Broadley-designed monocoque chassis.

The car that David Hobbs drove at Goodwood in 1965, though, was that of Harold Young Racing, which was chassis SL70/2. Chassis SL70/4 was returned to the factory soon after delivery to Hugh Dibley and the car was rebuilt using chassis SL70/7. The history of SL70/2 is told in this Bonhams auction offering.

Here's the car during the race at Britten's chicane leading the 1965 Elva Mk8 of David Clark and the 1963 Elva Mk7S of Ivan Scotti.
