Here's what we issued at Goodwood 2002 - first year it came over.

QUOTE 12 July 2002

TOYOTA 7

The Toyota 7 is, as its name suggests, an open two-seater built to sportscar racing's Group 7 regulations, as specified by the FIA, the governing body of world motorsport.

The original car was designed by the talented Jiro Kawano, the man behind the Toyota 2000GT, but development and construction were entrusted to Yamaha. The design was typical of a Group 7 car of the period, with the main cockpit structure made up of aluminium side sills and scuttles. The body panels were of glassfibre.

The prototype, first seen testing at Suzuka in February '68, had the DOHC fuel-injected, six-cylinder, two-litre engine from the 2000GT. This changed to a proper three-litre DOHC V8 all-alloy unit by the time the car appeared at its first race in March.

Just three years later the final iteration of Toyota's 7 had become a magnificent twin turbocharged 800bhp monster weighing just 620kg, but it never raced. In 1970 the Japanese motorsport's ruling body, JAF, changed the rules for Japan's key event, the Japanese Grand Prix, so Toyota had to stop development of the awesome machine it was developing for that year's competition.

Also cancelled at that time was a normally aspirated car with 600bhp from its 5.0litre V8. This car was intended to race in endurance events and could have brought Toyota to Le Mans over a decade earlier than it finally made it there.

Until very recently, this Toyota 7 sat defiantly on a raised podium at the Toyota Automobile Museum in Japan. Then a team of dedicated road car engineers led by Kazufume Toriya (the man responsible for ride and stability on Toyota's Prius petrol-electric hybrid car) undertook to bring the Toyota 7 back to life.

Originally rebuilt last October as part of an internal Toyota project to help its engineers appreciate the company's long-established motorsport heritage, the car has now been stripped down and prepared again before being flown to the UK to make its public debut at the 2002 Goodwood Festival of Speed.

Rebuilding the 7 was hampered by a lack of engineering drawings or plans to refer to, and many parts had to be rebuilt from the original. The engine of this 32 year old is particularly impressive as it uses many advanced titanium and magnesium alloy parts to help make the car as light as possible.

"I can see that our forebears did a fantastic job," explained Toriya. "My responsibility is to ensure their work is not allowed to fall into decay," he says.

Superb subject, Fabrizio!

Take a look at this link for more pictures and a three dimensional drawing. Your wheel design is spot-on!

Kind regards

Russell

That's a lovely neat job on the wing, Fabrizio! What shells are you using?
I have an old US injection-moulded Project Aston in my cupboard- it needs a lot of work to make it viable. I look at it every now and then, and put it back.
Keep posting this stuff- it's fab, Fab.
