Default The P1 vs. the i8 vs. the 918 vs. the NSX

Who's excited for some epic showdowns like we had with the F1-Enzo-SLR-Carrera GT days?? So excited!!!!

That and the Ford GT, which I hope to god Ford discovers the opportunity to bring the GT back to relevancy and create a hybrid supercar version. I would buy one in a heartbeat (in my head of course )

OH! I forgot about the LaFerrari, can't leave that beut out of the mix. And if Audi brings some of its Le Mans magic to make an R8 hybrid

Eh, I don't really care much. Partly because I care much less about any of these cars vs. their 10-20 year old ancestors, and partly because I'll likely never see any in person much less ever buy one.

You should care, at least a little bit, and at least about the P1. We'll see hybrid drivetrains in "pedestrian" supercars (Gallardo/458/R8) inside of 5 years, and that tech will trickle to sub-$50k cars within 10 years.

When will the first electrically assisted/complemented turbos surface on the aftermarket?
Ok, it's F1 currently, but will trickle down too I guess.

Electric turbos are nothing new. I've had one for years, they are very popular.

There is nothing to stop you from doing it yourself. Tons of DIY electric cars out there. I have dreams myself of running electric motors in the front hubs for "torque fill" and regenerative braking. But these are far off dreams...getting the dumb thing running is my immediate goal

I was referring to the MGU-H in F1 2014, a "normal" turbo which has a electrical motor attached to the compressor, making it possible to torque fill that way (spin the compressor electrically as a "response system") and to charge the battery instead of opening the wastegate.

I wonder how much of a 'super scavenging effect' you could create by spinning the turbo with an electric motor at low RPM. Basically creating a brief state where the engine is not only getting some boost from the compressor wheel spinning, but also having ex. gases drawn out due to the turbine spinning. Probably would have a span of like .5 seconds in an environment like an F1 car before you had the ex gas volume come up due to the boost, but it is sort of cool. In a road car you might conceivably get a really efficient lean AFR burn thing going for economy.

This is a good point. What I'd really like are aftermarket "hybrid" kits you can retrofit onto non driving wheels e.g. make your Mazdaspeed 3 a sort of AWD hybrid by having some electric motors retrofitted to the back. Would probably drive like crap though unless you had a pretty sophisticated controller to control the "throttle" on the electric motors.

Aftermarket hybrid installs build as flywheel/clutch replacements (there is space to do something there at least)?
Reasonable similar solution on all cars I guess.

Ah, I hadn't thought of that! I really like that idea but I'm sure it is tricky getting a generator to work near/in such a high heat area. I wonder if you could extend the compressor shaft into another set of bearings then to a generator to avoid exhaust heat somewhat.

I see how they did it for the F1 car, really cool stuff. Can't believe I hadn't been paying attention to all of the new tech they introduced o.O

Pretty much this. And look at the S class for future safety standards and other things of that nature.
