Great endurance racing this weekend at LeMans. Audi e tron diesel with flywheel recovery system outlasts Toyota super capacitor recovery system and out runs Porsche battery based hybrid systems. Toyota was running much faster and looking like it was easily going to outrun everyone, but retired due to electrical issues. Will be a interesting next few years sorting these various systems out.
 
I think audi's advantage may be diesel reliability !
Audi and Toyota have been running, racing, and developing these hybrid systems for several years.
Audi first won LeMans with the Williams developed flywheel hybrid in 2012..the Toyota hybrids crashed out that year. !
FYI..the "Flywheel" unit simply replaces a battery as an energy storage device,
The wheels ( front on the Audi) are powered by an MGU that collects the regen energy to spin up the flywheel, which then releases the energy (electrically) back to the MGU for acceleration. Its capable of 150kW.
 
I know Jaguar are testing the Flybrid system in the uk, it is looking very promising as an aid to fuel economy.

I was watching Flybrid about 6 years ago. I hope to see that in road cars soon!
 
We are witnessing a completely new chapter in history, and it is exciting to say the least. Every time I pull up a youtube video for my mates of an emotorcycle or race car they are just in complete amazement.
 
I guess for those of us who are following the technology none of this is a surprise , ...in fact often frustrating that technology is not being applied faster both on the track and on the road.
But for someone who has their head into other things, bikes, ball sports, work, fishing, family, etc etc...then when they suddenly realise that a"hybrid" has won LeMans,..then it's a bit of a shock.
I was watching the race live with a friend and his 20 yr old son who was obviously enough of a "petrol head" to enjoy the racing, but he laughed out loud when the commentator repeated the point about a Hybrid winning......he thought the commentator had made a big mistake and just ment Diesel not petrol.!
He was blown away to learn wat is going on with these cars.
I would bet that of the millions of viewers who watch the F1 races and understand that KER,s and ERS systems are used,....
....few will actually comprehend the true implications of what it means and how much to impacts on the performance, both in terms of speed and efficiency.

I can remember about ten years ago that flywheel's were to be used in bus's which makes perfect sense cause of all the stop starts, but what happened to that? a small compromise in space for a huge benefit in fuel usage, :roll: at least we are starting to see changes but it has to be proven on the track first
 
The flywheel effort dates back to the 1970's. These things take time.

And speaking of time, do you know who had the fastest in the Formula E testing?
