McLaren P1 will do battle with Porsche's 918 Spyder

The McLaren F1 is a legendary supercar that still commands respect two decades after its initial introduction. Labeled by many as one of the greatest -- if not the greatest -- road car of all time, following up on such an iconic legend is a tough task.
McLaren is now ready to pass the touch onto an equally impressive machine: the McLaren P1.
Although the P1 was first unveiled to the public last year, we're now getting some detailed information about the vehicle's powertrain. Whereas the F1 used a normally aspirated, BMW-sourced V12 engine, the P1 uses a twin-turbo 3.8-liter V8 engine paired with an electric motor. The twin-turbo V8 by itself generates a whopping 727hp and 530 lb-ft of torque, while the electric motor tacks on another 176hp and 191 lb-ft of torque.
When combined, the powertrain is good for 903hp and 663 lb-ft of torque. While impressive, it's still not enough to match the sheer power of the two-ton Bugatti Veyron, which is rated at 1001hp and 922 lb-ft of torque. Unlike the Veyron, however, the P1 likely won't weigh as much as a midsize SUV.

McLaren states that the P1 can travel up to 6 miles on battery power alone (the vehicle's lithium-ion battery pack weighs 210 pounds), and the vehicle can be plugged into a household outlet to recharge.
Performance figures for the McLaren P1 aren't in yet, but we can't wait to see this latest hybrid supercar do battle with Porsche's upcoming 918 Spyder.

0-60 will barely benefit for any test where you drop the clutch (i.e. every test car magazines do), since a RWD car with 727 hp would be entirely traction limited.

It'll be felt more for its instantaneous response, especially if the turbos aren't yet spooled up. I do agree that 1/4 mile times will improve.

The Porsche Spyder is different from what I understand. The Spyder has an independent power source on every wheel (electric motor) + ICE. This car has a giant electric motor up front with the ICE.

A Bugatti is pure straight speed, I don't think you'd want it on an actual race course. Also check the MPG on a Bugatti. Obviously you don't want to race in an econobox, but MPG is important in racing and these hybrid systems deliver performance on par with ICE at a significantly higher efficiency.

Maybe I'm wrong, but these power trains are getting pretty advanced.

The main innovation here seems to be that they built the electric motor into the engine block, which is pretty awesome.

That's called the starter, and car's have had them since they got rid of the handles that liked to break your arm. McLaren's is simply bigger.

Not exactly.. Starter motors bolt onto the block but they're not cast _in_ the block. A neat way to save weight, but I'm wondering how it'll impact servicability. I assume it's also basically a starternator, so the alternator can come out too, saving more weight and complexity.

In fact, if these guys were smart, everything that would hang off the motor as a belt-driven accessory is electric instead, thus removing the belt, the clutches, etc. and both reducing complexity and increasing reliability.

Pretty fun watching the debate when none of us are likely about to purchase any of the cars mentioned.
