Apparently there was some pace left on the table even with that record-breaker.

Hybrid Makes sense, instant torque exactly where you need it on the lap, that's going to be very tough to beat. Rear engine p-car with no-hybrid.. definitely have no chance of claiming a faster lap.

However, the hybrid thing is a bit of a "One Lap Wonder". As soon as the battery wears down, no mo' instant torque. So, I wonder if this approach will really work in a GT-3 or GT-4 Porsche?

Well you have to think about the 919, when did it have to go into the pit to be charged? Is energy recovery as far as it needs to be yet, likely no, but it does make the hybrid systems viable for racing.

commercially it will absolutely work. The typical GT3 buyer is not going flat out for 7 minutes neither are they doing any track work. Only a very small part would empty the cartridge so to speak. For the rest it's just a here and there type thrill to wow their buddy in the passenger seat. A sort of glimpse of what a record N-ring lap feels like.

But in the long-term, hybrids are here to stay in track-oriented sports cars. It's just the start before they go all electric.

Data says that 70% of GT-3 owners track their car. Still not sure how batteries will work in a GT-3 or GT-4.

I heard Porsche throw out that figure, I've also seen 80% by them.
I'm thinking they are including folks who have attended at least one beginner's PCA DE and counting that as a
typical track driver. Porsche do not stand by their warranty once a GT3 hits the track. Are 70% of those owners saying "F*@% it... if I blow up the engine at Sebring today who cares"?
I'm skeptical...
If you poll owners for those who track their GT3 at least twice per year, I'm thinking that 70% figure comes down substantially and more inline with typical Porsche ownership.

As for the hybrid stuff, maybe the Cayman GT4 will be a sort of high performance guinea pig.
A 425 HP mid engine, shorter wheel base Porsche is bound to attract the attention of a lot of track drivers. Well ones with deep pockets. c7 with track goodies on board can be had for same money and a full warranty to boot.

thstone - as far as battery regen goes, I imagine they'd use regenerative braking: Formula 1® - The Official F1® Website - Understanding F1 Racing - Energy Recovery Systems (ERS)

Because the high-torque power demand typically follows a braking event, the power is available on corner exit.

A similar system is used on many road-going hybrids & electric cars.

Full disclosure - I HATE traditional hybrids & electrics (and their pretentious owners).

It wont be a "One Lap Wonder". The F-1 cars use some form of the technology now in the 2014 cars. Instant torque would be something to get used to though.
