Flybrid-Hope-Lehmann-Oreca LMP1
Saw this yesterday and thought you bunch might be interested, certainly some interesting images and an interesting read. Flybrid are now using their own clutch technology instead of the ToroTrack constantly variable transmission widget, which I bet will save them a fortune on licencing costs.
looks hard to believe that it will fit between the engine and gearbox when you consider they are using an I4 engine layout.......but thats what it says, I'm thinking it must be a 2-piece bell-housing??? I really believe this is the start of something good for Flybrid, this system really is very simple when compared to what Williams have done with Porsche, but strictly speaking thats not an apples-apples comparison - spec wise........even the Chief Engineer at Honda has openly stated in the press that its going to take 20 years for battery technology to reach a point where its performance and cost is acceptable for the mass market. Best of luck I say! ps - I am in no way whatsoever associated with Flybrid! . |

yup, the latest Feb 2011 edition of Race Engine Technology magazine which I subscribe to, see www.highpowermedia.com for more info, I dont think you can buy it in many shops as its quite specialist, not cheap either at £10 / $20 per edition.......as its a 74 page magazine, so that means everyone now owes me 13.51 pence each ;-).......if you are looking for more information, Ian Bamsey is the man to get hold of, he is the editor.

No problem, primarily if you are looking for a real scoop, I would get in your car and go doorstep Jon Hilton at Flybrid, I'm sure he will be only too pleased to have DSC do a feature on Flybrid and their plans for LeMans........Jon is very active in the powertrain press.

Since the Lehmann engine is basically a VW road car engine modified for racing and Porsche's experience with the Williams F1 flywheel system, could this be in a way a toe in water exercise for Audi and their plans to field a hybrid version of the R18? Especially when you consider the VAG links and the flywheel system that's much lighter and more compact than the system that Porsche uses.

With a battery KERS this is quite simple because it is like driving on the starter motor and the battery can be charged beforehand. |

you are completley correct and I'm really puzzled that hope will be forced to comply with this test, its stupid, it only really applies to electrical traction motor hybrids.........

The point is for the ACO to confirm the car is capable of moving under its own (electric only) power, part of the rules for hybrid technology. Heres to hoping for a good test day for all involved.

That makes sense. For some reason I thought that they had to run in the pitlane in electric mode during the race, but I didn't actually see that anywhere.

And when you consider that Peugeot ditched plans to run the 908Hy4 at LM because of reliability issues, it's of little surprise to me that the smaller private teams are having hit and miss success with their hybrid systems.

Between the AMR ONEs and the hybrid protos I fear more forfaits coming before the Le Mans race
