Title: Le Mans should be interesting...
Post by: Kevin Wood on 11 June 2015, 10:11:07
An LMP1 car with front "just nipping down the shops, dear" wheel drive. (https://dl.dropboxusercontent.com/u/26795734/Smilies/doh.gif)

Fair play to them for trying something different, but it can't work, can it?

I like the look of that. All wheel drive when required. Wider tyres at the front than the back. Can't say I have ever seen that before.

Lets hope it is more reliable than F1 Mercedes or Honda units.

Well .. last year (I think?) they had a triangular car so this is practically normal for them ;D

I think what I like about the new car (having just watched the first few seconds of that video) is that it looks like a sports car should again - long nose, bonnet bulge, short tail.. echoes of classic design :y

The video is worth watching, there are two tunnels that run the length of the car for aerodynamics. The KERRs (or their version of) is actually a mechanical 'flywheel in a vacuum' due to the speeds it reaches.

Excellent video. J Leno for Top Gear.

Not sure I would want a Kers flywheel near me spinning at 52,000 rpm even if it is in a vacuum. These sort of inovations will make there way onto road cars one day. I also liked the young lewis hamilton looky likey.

I am thinking that front tyres will be their bogey

Yes, I would worry that the flywheel could overspeed.. And, if it can store enough energy to generate 750 BHP, what happens if you crash? :o

Tell that the the guy in an alcohol-induced coma lying in a sleeping bag, surrounded by lager cans, on the banking at 3 AM. ;D

That may help the crowd near where the accident happens. It doesn't necessarily mean that the flywheel will land anywhere around that area.

I'll text my friend Chris as that sounds like a pretty accurate description of him at LM ;D

S e gf the Indy cars have taken off when they spin and end up pointing backwards. The aerodynamics reverse and whoopsy! Up she goes.

This has even less protection for the driver by the looks, if it goes in backwards.

Interesting to see how it goes. Aero dictating front wheel drive aye? Hmmm.

Lemons is on now n Eurosport btw. TT set to record.

Was looking at this very link prior to logging on tonight.

Wouldn't fancy changing the cam cover gaskets. :o

That's probably a service part.. and by service part I mean they throw the engine away and put a new one in ;D

The company I work for makes these type of flywheel energy recovery systems, amongst many other cool bits of tech. Their application won't so much be for road cars due to the way they work. Road cars tend to either be on long motorway runs or stop start traffic. Neither of which generates the deceleration momentum required to power up the flywheel.

Where they will (and already are) coming into use is on buses, due to their increased mass over a car and frequent deceleration from c30mph they make great candidates for this sort of tech. As do certain delivery vehicles (think US mail trucks). The problem is one of miniaturising the technology, the smaller (and hence lower mass) the flywheel is, the faster it has to spin. Ours are larger and operate at around 45,000 rpm. But we're also making ones for the Audit R-18 which operate at similar speeds.

Yes, the way it's going to be driven, I'd be surprised if the engine lasts as long as the cam over gaskets. ;D

Interesting stuff.  :y

Yes thanks for posting Jimmy. :y

One of the Nismo's dropped out, wheel came off after a pit stop, got it back but had to retire.

Audi and Porsche still swapping for the lead after each stop. So close, and so little in the way of dramas up at the sharp end.
