Six-Wheeled Covini - What's That About Then?

Italian supercar creator wants more than four wheels on his wagon...



One of the more oddball creations at the recent Goodwood FoS was this, the Covini C3A, a six-wheeled supercar with an 1150kg kerb weight, a 500bhp 4.2-litre Audi V8 and a 190mph top speed.

Apparently the car, which has been a pet project of creator Ferrucio Covini since 1974 and is now being developed by his son Gianluca, offers several advantages over cars with a mere four wheels.

Not least among these is the assertion that "four front wheels offer the ability to get around a racetrack faster than ever before as better traction offers higher cornering speeds and deeper braking, particularly when the pavement is slippery or less than ideal".

There is also the increased stopping power of an extra set of discs, four tyre treads, and the increased passive safety afforded by two front wheels at each corner (which means a front tyre puncture will not cause the vehicle to lose control).


When you put it that way, why don't all cars have six wheels, Gianluca?

Perhaps part of the answer to that one is that six-wheeled cars have often been the creation of - how shall we put this politely? - somewhat eccentric folk.

As editor of Classic and Sports Jacket (and chum of PH) Alastair Clements succinctly puts it:"The biggest problem for Covini will be persuading enthusiasts that it is a serious proposition, not just a gimmick: history is peppered with six-wheeled laughing stocks, from the twin-turbo Caddy V8-powered Panther Six (see above) - good for 200mph (yeah, right) - to William Towns' delightfully unhinged Mini-based, plywood-bodied Hustler (with its four wheels at the back).

"There must be some technical merit to the layout, however, or various Formula 1 teams wouldn't have experimented with it, most memorably with the Tyrrell P34. But then in that case designer Derek Gardner was using smaller wheels to reduce drag, something that isn't an issue with a fully enclosed supercar."


In all honesty, then, we're not entirely convinced of the benefits of six wheels, but it does afford us the opportunity to post a link to this fabulous video of a wide-lapelled fellow interviewing Panther boss Bob Jankel.

Our favourite bits? Jankel's confident assertion that the Six would be "in production in the early part of next year". Or possibly the presenter's explanation of the advantages of a car having six wheels: "Under heavy braking on a wet road the front wheels lock up, leaving a dry track for the next set of wheels to grip". Ermmm... right...

Personally I don't even drive on the pavement- but maybe thats just me?

One of the worst looking and stupidest creations in existance!

isn't it the constantly changing geometry that always unhinges these things? castor & camber, ackerman's angle & tyre scrub send the blokes with the protracters & rulers round the twist befor they can get the cars into production.





apparently?

I would have thought you could set up one pair of wheels and then get a computer to work out all mount points and component dimensions to minimise the scrub of the second set across the full spectrum of suspension deflections.

i'd have to dig out some obscure book at home to look it up but i think it's way more complicated than that, if i remember correctly it the tyre scrub was kind of acceptable on a race car but on a road car it was all but impossible. the answer was thought to be in constantly varialbe pick up points for one pair of the front wheels but i think it's complexity ruled any advantage mute.

interesting to see the tyrell six wheeler's main advantage being stated as low drag again, derek gardner had admitted a few times that was a complete myth-from the begining they were chasing increased front end grip improved braking power though apparently the lower front end did contribute to less lift on the front end.

Covini just need to set a sub-7 minute lap around the 'Ring and people would start taking them seriously. If its so good, they should take it there (like every other manufacturer does). I wonder why they haven't? rolleyes

The only reason it would have more front end grip over a conventional single axle front end is weight, if for example it weighed the same as a normal set up it will have no additional friction at all in the corners because the load is just spread thinner.

However, i am guessing this weighs quite a bit more than a conventional set up so in theory it can generate more lateral grip from its greater contact area but in my opinion that heigher levels of grip could be generated by increasing front end downforce on a convential set up which would be simpler, lighter and cheaper.

Im shooting a bit from the hip here as that is only my idea on the theory but in my opinion its a gimick and an ugly one at that.

They didn't look like they had much confidence in its handling capabilities when they drove it at only 30mph up the Goodwood hill on the Friday. That spoilt a lot of people's enjoyment of the Caparo (and subsequent supercars) which had it's run ruined by this joke.

Still, it is probably just a prototype at this stage - it certainly only looked up to prototype standard when I saw it in the supercar paddock. The interior was of especially poor quality. I doubt they would have gotten much in their order book that weekend.

I'm ordering a Covini as soon as I get my Lottery win sorted!

It does work. See my vehicle below...

There must be some science behind the theory. It worked for Lady Penelope.

Didn't the bus in 'The Italian Job' have four front wheels?... and look what happened to that!!! If anything it had too much front end grip...

Commercial vehiles have had two steering front axles for decades, so the science is old hat and well sorted by now.

I actually like it, getmecoat
