Novel BEC approach.
Most BEC builders ponder the possibilities of connecting a chain drive bike engine to a propshaft and diff.
This enterprising builder has stuffed a Guzzi engine into the back of a Fiat 500 and connected the shaft drive via chain to a live axle.

Is it just me, or has he missed adding a diff. - the driveshaft looks like it runs solid the full width of the car ?

I think you're right, you'll probably find that its some kind of dirt-track car where you wouldnt need a diff as you'd be constantly
sliding the back end to turn in.

You're correct; no diff. AFAIK, it's a road car too.
There are plenty of cars around the world running locked diffs/solid axles/Detroit Lockers/spools etc. There must be thousands of Saturday Night
Specials running BOC (as in welding gas) diffs too.
It just requires a modified driving technique which is the small sacrifice those people pay for superior straight line performance.
Many race series that run on bitumen mandate locked diffs, such as the Australian V8 Super Cars.

I guess if you dont mind chronic understeer, especially when off the power, then its a cheap way of turning the wheels

No diff on a Noble!?
The noble m12 has a LSD, according to the road tests, and every website I can find.
Are you sure?

F1 cars have the most complicated electronic controlled diffs there are in any car, thats where they make big gains in traction.
Every standard road car I know of has a conventional diff be it it open or of limited slip flavour. It really would be nigh on undriveable without
serious alteration to driving style and a hefty right boot to get it round the tighter corners. If youve never ridden a quad bike then first time you
come to a tight corner, keep the power on otherwise you'll go nowhere but straight on, you really do need to steer them on the power - ditto
go-karts.

Back to the original title of the post
The lancia abarth built by Micke Fredriksson (now on the site building a trike!) used a R1 engine under the bonnet, turned round 180 degrees (i.e.
sprocket at the front), connected by chain to an upside down BMW diff, driving the front wheels.
I'd love to have a go in that.
Although - wouldn't the diff be driving the 'wrong' way - i.e. not the way it was designed?
Still looks great though.
see - http://www.locostbuilders.co.uk/viewthread.php?tid=20350 for piccies.

A locked diff or solid axle isn't all that bad. One of the main reasons family sedans use a diff is to prolong tyre life.
I do accept an open/slip diff does make normal driving easier, but you can't compare a quad with its very high COG with a properly engineered
car with a locked diff.
If you watch any of the televised races where locked diffs are specified, you'd be hard pushed to notice they weren't running an open
diff.
I think every true petrolhead has at least once got the welder out and given themselves the thrill of a locked diff.
After the novelty and most of the tyre tread has worn off, most people realise that an open diff is cheaper on the public roads and requires less
effort too.

Doesn't Noble use some Ford MTX75 transaxles?

My concern would be cooling and enclosed aircooled motor!

I can only assume he's thought of that and addressed the issue.
I'd agree though, that motor stuck in there withought adequate cooling air directed at the heads and barrels would soon cook.
