I agree with you. Also La Ferrari has 360kg of downforce and McLaren 600kg, I think it makes up for the 47bhp deficit. In race mode P1 sits so much closer to the ground.NoDivergence wrote:Don't think so.

47 Hp down for how long? The P1 has no useful capacity for energy recovery in track driving, so once it has the batteries fully depleted it's at a big disadvantage.Felipe 92 wrote:I agree with you.

To be honest I have never read that P1 can't have energy recovery whilst in race mode as you suggested. Talking about acceleration figures both cars are matched until the 180 mph mark. And there isn't much racetracks where you can reach more than that for a significant amount of time.Cold Fussion wrote:

Here is what Autocar's Steve Sutcliffe comments are about energy recovery for each of the three Hyper carsFelipe 92 wrote:To be honest I have never read that P1 can't have energy recovery whilst in race mode as you suggested.

What separates them mostly obviously here, though, is the way they harness and redeliver their electric power. In the 918 and P1 you quite quickly run out of e-puff if you drive them hard for sustained periods, and the only real way to get it back is to slow down a bit until the batteries can regenerate, mainly via the engine in the P1 (on a small throttle opening in a high gear) or via the brakes in the 918.
In the Ferrari, however, you harvest power all the time, and there is no 'e-mode' as such. As a result, you have access to the full 950bhp all of the time, which effectively means you have another couple of hundred horsepower to play for much of the time.
But on an overall lap, you are more on the throttle than off.. so therefor probably the batteries will not be recharged enough to go flat-out all the time...?ltitus wrote:Steve Sutcliffe put his for in his mouth in this video. The P1 regenerates on deceleration. So every single second you get of the throttle the batteries are recharging.

The P1 has no regenerative braking, and no exhaust recovery. The only time the car recovers energy is in off throttle situations (potentially partial throttle?), so in a racing situation where you rarely ever lift and coast, the P1 wont be regenerating energy. It's possible they could use the regeneration as a traction control, but I suspect this is unlikely to be the case. Both the 918 and LaFerrari do regenerative braking, so both are able to have long sustained period of electric power available, unlike the P1.Felipe 92 wrote:To be honest I have never read that P1 can't have energy recovery whilst in race mode as you suggested.

The car can be run in a full-electric mode for about 10km, a hybrid mode in which the ECU seamlessly meshes power from the ICE and electric motor, i.e. all 904bhp are available for use, but not necessarily all at once, or it can be run in "race mode" in which the electric motor supplements the ICE on-demand rather like the KERS used in F1 from 2009-2013. Only in the latter mode, with IPAS engaged, will the car be powered by all 904bhp at the same time, and electric power is limited in all cases by the length of time spent off-throttle.
Because LaFerrari employs regenerative braking and harvests energy from its differential, it has 950bhp all the time. It also has a higher power-to-weight ratio (707bhp/tonne vs P1's 623bhp per tonne). Whether or not that's enough to make up for its relative lack of downforce (~500 lbs at ~120 MPH vs P1's 1320 lbs at 160 MPH), I dunno.
I think it's likely the P1 will be marginally quicker around the Nordschleife, but only on the first lap.
(I also think both cars, and the 918 Spyder, are soooo much more exciting than anything in F1 right now.)
