1977 Tyrrell P34

History of the P34
One of the first rules of aerodynamics, is to provide as small a surface to the air as possible (frontal area). To do this, Tyrrell designer Derek Gardner started by reducing the diameter of the front wheels to just 10 inches (25cm) so they could be tucked completely behind a front fairing. The reduced size of the tyres reduced the contact patch, and grip area provided by the tyres. So a second pair of wheels appeared behind the first, both steering. Although radical, the cars only win headed a 1-2 in Sweden 1976, with Jody Scheckter and Patrick Depailler. Not many teams have followed this example, and the FIA's definition of a car in the current rules, is one having 4 wheels. Six wheels are now consigned to the history books forever. So what do the history books say?

The First Six Wheeler
The first car to compete in a World Championship Grand Prix with six wheels was at Indianapolis in 1957, in this case Jack Turner in a Kurtis Kraft-Offenhauser KK500G, also known as the "Pat Clancy Special". So that Formula 1 could truly become popular world-wide, the governing body rightly targeted the Indy 500 as a way of breaking into the American market. Drivers competing at Indy would earn points towards the Formula 1 world championship between 1950 and 1960. Therefore, this is the first example of a six wheel car in the official Formula 1 Championship.


Other mutli-wheeled Grand Prix cars
Ferrari built a six-wheel version of the 312T2 in '76. The car, dubbed "T6" had twin rear wheels on the same axle, like the pre-war Auto Union mountain climbers of Stuck, or the Raymond Mays ERA hillclimber. Ferrari reckoned that the thinking about the Tyrrell and reduced frontal area was correct. But unlike Tyrrell they didn't agree that frontal area was the first point of air-penetration, they reckoned it was everything you could see from the front, including the visible front area of the huge rear tyres. So they reduced this by fitting four normal front wheels in-line and on a single rear axle.

Both Lauda and Regazzoni drove the T6 quite a bit in testing and Lauda was actually quite happy with the car and at one point considered racing it as the championship was looking to go his way and therefore Ferrari could afford some time developing the car under race conditions. Lauda's accident in Germany put paid to that idea and also the notion that the car may run at the Italian GP. The car was put away but not before allowing Polistil to build and sell a 1/16th diecast model of the car which was released sometime early in 1978.

If you ever come acorss magazines from 1976, look out for a picture of another Ferrari multi wheeler, an 8 wheel car being tested by Regazzoni, 4 on the front like Tyrrell, and four at the back like the March. Dubbed the Ferrari 312T8, pictures appeared in the press comlpete with exploded diagrams of how the car worked, which if you think about it is a pretty daft thing to do if you are developing a new concept for racing.

Problem was, none of the Paprazzi who permenantly camp round the chain-link fencing at Fiorano could confirm ever seeing the T8 in action. Some years later Ferrari came clean and admitted that the picture they released was a mock up, the T8 never did exist but was purely an exercise designed to keep people thinking about what they were up to next, which at the time was designing and building an Indycar, tested in the States but unraced and intended for Mario Andretti to drive until he decided to stay with Lotus.

Williams attempt cut short



The last time a six-wheeler was built was in 1982 when Williams produced the FW08B, but the same old story kept cropping up during testing, it wasn't any faster, nor slower than a conventional four-wheeler. The decision to stop development was made for them when the FIA outlawed four wheel drive, and then later they outlawed four wheel steering and just in case anyone still didn't get the message, they stipulated four wheels only and then only the front two could steer. The FW08B was put back in the Williams museum until dusted off for Jonathan Palmer who managed to score the fastest time of the day at a Goodwood Festival meeting a few years back, then it was put away again.

Even terugkomend op de MX-5, ik bedacht me net dat er wat werd gewhined over de nieuwe 1.8, die is nl. 124pk - heb net even zitten kijken bij autoweek, de oude 1.8l had 146 pk!
Ik heb dus ook even in de 1.8l 3rd gen van mijn collega rondgereden en dat reed nog best vlot. Je krijgt sowieso al een snelheidsgevoel omdat je veel meer onderuit ligt dan in een 'standaard' auto.

Welke "oude" bekijk je dan? foto?

Want 1st gen heeft toch maar 131 pk?

Dan moet je al helemaal niet naar een 2nd gen MX-5 kijken

Ik bekijk alles dat is het hele probleem
E36 M3 leuk maar motor kan je na 150000km op schroot gooien + E36's roesten

je bent nog steeds een prut0r

Google images toont geen enkele constantheid als je zoekt op Porsche 977, daar kun je een conclusie uit trekken, allemaal typefouten in de bestandsnaam dus

Ik haal het niet uit foto's Er zijn stuk of 10 sites met 977's erop

hmm, je hebt gelijk... vanaf de 2nd Gen heb je 140 tot 146 pk in de 1.8l (volgens de fabrieksspecs van autoweek anyway... dat is na x jaar ongetwijfeld minder)

Kun je geen engine-swap doen?

bmw 2.5 6 pitter erin?
