Ferrari looks to take on Porsche, McLaren

It looks like the hybrid supercar wars are on, and Ferrari has fired the latest shot. Porsche revealed the 918 Spyder, McLaren went official with the P1, and now Ferrari has the… LaFerrari.
The LaFerrari is the successor to the Enzo and brings with it an 800hp V12 engine that revs to an eye popping 9,000 rpm. Its peak torque of 516 lb-ft is reached at a "lower" 6,750 rpm. In addition to the V12 monster behind the driver, the LaFerrari also features a 163hp (199 lb-ft) electric motor.
With all of this power on tap, Ferrari says that the LaFerrari can scoot to 60 mph in less than three seconds and hit 124 mph in under seven seconds. The LaFerrari will keep on accelerating at an astonishing rate (186 mph in 15 seconds) until it reaches a top speed of 217 mph.

Not much else is known about this crazy hybrid other than the fact that is has 41/59 (front/rear) weight distribution, 19" wheels up front, and 20" wheels in the back.
As we get more info on the LaFerrari, we'll keep you posted.

The electric motor makes more sense for a turbo engine car because it makes up for any lag, but most Tesla reviewers say that the the instant response is significant over even naturally aspirated cars, so I guess that's a reason.

The valvetrain requirements of a typical NA engine change as the RPMs do. The camshaft profile for lower RPM power is quite a bit different than trying to make power at higher RPM.

For example, in the small block V8 world, many people change to a different cam. The more aggressive the cam, the worse the engine performs at low RPM. More power at the top end, but very choppy and laggy at the low end, even when still normally aspirated.

To solve this, some makers use VVT employing several lobe profiles, or even just cam degree'ing.

But, having a low end assist in the form of an electric motor leaves the engine designer to only concentrate on the top end. That's one of the reasons why you see this Ferrari hitting 9000RPM. You don't have to worry about low RPM performance anymore.

Interesting. That makes sense.
