i cant think of a way reason why it would be illegal

AlexF

There are plenty of twinies on the road - so I assume not!

How would they do the emissions for MOT? would they combine the 2 ngines emissions or would they test them as sepperate?

Oranoco

You're mates prob talking shit to try and look clever. Dubsport, Euro-Whatsits and MJS have all done twin engined cars and I'm sure all are road legal

djmillsy

ive heard this also not that long ago you cant have two engine cars on the road legally ah it was on scrapheap challenge

focusv8

I've read but can't find a link, (still looking) that there is no problem with the second engine being fitted but it has to be disabled on the road and for MOT.
Emissions wouldn't be a prblem if the exhausts combined at some point.

If two engines was illegal, you could argue that all the Honda IMA, Toyota Prius and Lexus hybrids are illegal too as technicaly they are twin engined.

Personally i think its a case of bar room bullshit.

A mate of mine had a twin engined Mini on the road a few years ago

am sure it is illegal to use both engines on the road at same time, but not illegal to have to in the car

I was told a, that it is illegal to have a second engine running whilst on the road, so those cars only drove on one on the road id imagine.

djmillsy

thats what the law says you can have two engines in a motor but not runnig when on the road

focusv8

Twin engines done by a major manufacturer will have type approval and will be legal to use.

Guy at home sticking 2 mini engines in one body is a completely different thing.

why is it so bad to have 2 engines running on the road do you think???

djmillsy

Where would he sit

If they both drive through different drivetrains and one engine stalls, you could effectively have one axle locked up and still attempt to drive the other, causing possible handling problems.
If they both drive through the same drivetain it should be O.K and legal.

Squints twin engined Escort RST pick-up not NOT road legal...

Nor was hs blue one (even though it had an MOT lol

DENNIS

interesting one this ....

i am sure there is a kit car maker that have a twin bike engined car ????

as long as it is structurally safe and strong i cant see why not ?????

as for the Axel locking on a non running engine, i don't think that would happen as most cars have fuel cut off on over run and they don't lock !!!!

as for emission's on the MOT, if the two exhaust systems are joined at some point it would be just taken from that. But if the systems are totally separate they would have to take the readings from both and multiply them together...

you would also have to completely seal the rear engine from the passenger compartment for safety ( think V6 Clio !! )


would like to see more twin engined cars !!!!

No-one seems to know mate. I think I'd try DVLA direct to see what answer they give.

this has been put up on here before im sure and didnt someone find a
link to the law on twin engine motor's

Fast Guy

Can't be illegal or they wouldn't be producing these for example.

What's the difference between having 8 clyinders or 2 lots of 4 (that's a rhetorical (sp?) question btw)

focusv8

Both engines drive into a common transfer box driving only 1 axle.
