The twin-engined car concept has been done a few times, I rmember the twin-engined Audi TT on Top Gear a few years back. My friend subjected me to some max power dvd thing some time last year that had twin-engined Vauxhall Astra/Nova/Calibra/something else that wasn't really worth the effort. They put it in a drag race with a bunch of other boy racer's wetdream cars. If memory serves, they all got spanked by a squillion horsepower Nissan Pulsar.

To conclude, I think the general concensus is that it's more hassle and weight than it's actually worth. Just having a bigger engine in the middle of the car is a better solution afaik.

About the mini, theres a company that builds them with motorbike engines, some versions are twin engined ones, i have no ideia what they's site is, but i'm sure i've seen it on the net

Beware the irritating commentary.

EDIT: The twin engined Mini I think you're talking about is the red Autograss racer that's got two 160bhp Yamaha R1 engines in. Only thing is, it's a totally custom car, the only Mini bit is the bodyshell...

what about having one engine power the left, the other the right?
then the split pedal could (with practise!!) be an advantage.

i had the idea a while ago to have the left and right sides of a car on seperate brake circuits. then have the pedal able to rotate at its pivot. so then the face of the pedal could be slightly wider than normal and the driver could slide his foot to the left to increase the braking on the left etc. i dont know if this would really give much of an advantage but it might allow one to brake later into a turn since you could vary the brake balance as thw weight shifts as you turn in.

There is a twin-engine VR6 Golf knocking about- it IS awesome. 0-60 takes 3.1 seconds, and the top speed (before one of the engines screwed an oil tube) was 175mph. Has anyone seen it? It's a bright blue thing, not unlike a few of my chops

There was a twin VR6 Scirocco at Waterfest this weekend. I was too tired to hunt it down to take pics, but I'll see if I can find anything.

Thank you... Jeez, look at the dials on the dashboard, it's like the guy has raided Halfords and only stolen from the "Extra gauges" section.

What about the Volkswagen W12 Nardo, the Bentley Continental GT, and Audi A8?

They're not twin engines, the W engines have a single crankshaft.

Also, some small japanese cars had an option for an electric motor to drive the rear wheels, thus creating psuedo AWD. I've not heard of this being an option outside of the country, though the Mitsubishi Eclipse concept had the same thing going. Interesting how the 2CV Sahara had separate gearboxes.

Man, talk about over-complicating things!

I imagine it would require an extraordinary amount of skill to be able to shift the brake balance to either side of the car. Plus it could make heel 'n' toeing a bit, erm, 'eventful' shall we say!

I know the McLaren F1 team had a "brake-steer" system on their late '97 and early '98 season cars, but sadly they were banned due to Ferrari's bitching and moaning! I believe the McLaren system used a seperate, smaller brake pedal just to the left of the main brake pedal. The second pedal sent more brake bias to the REAR of the car, not from one side to the other.

I think the idea was that the driver would roll his left foot to the left and feather the small brake pedal on turn-in to help kill any turn-in understeer. I think they also used it on exiting the corner to give some mechanical traction control benefits, I guess in a similar way to how some Moto GP riders feather the rear brake under hard acceleration. (At least that's what I remember from reading about it at the time.)

Why not.... get a computer to do that? single pedal and the PC computes the angle of the car, suspension geometry, and other important factors and distributes brake force

How about the Tiger Z100? Twin motorbike engines, one for the front wheels, one for the rear? The Tiger Z100WR was the quickest thing to 60.

it 's RWD.
The two bike engines drive into a transfer box which combines their output.
It doesn't need AWD as it is light enough to be faster with RWD only.
