Big news this week in the supercar showdown.

McLaren has detailed some of specifics surrounding its P1. Considered the brand's flagship and follow up to what is largely considered one of the best supercars of all time, the McLaren F1, clearly the P1 has big boots to fill.

Something tells me it may just do the job though as its bi-turbo, 3.8-liter V8 engine produces over 900 horsepower with the aid of an electric motor.

This news must have the folks in both Maranello and Stuttgart a bit...concerned. Ferrari and Porsche are set to unveil their latest supercar projects, the codenamed F150 and 918, in short order.

While all the aforementioned automakers have mentioned bringing racecar technology to the street, it seems that McLaren has been the most adept at doing so thus far. Between the implementation of a KERS-like system that McLaren's calling Instant Performance Assistance System (IPAS), a Drag Reduction System (DRS) and a full-on electric mode, it's certainly sounding like McLaren is shaping up to take the best all-around supercar on the planet, again.

As expected, the P1 uses a twin-turbo 3.8-litre V8 – developed from the one in the 12C – and an electric motor for a total of 903bhp. Both deliver power to the rear wheels through a seven-speed dual-clutch gearbox, and while McLaren hasn’t revealed performance figures we’re expecting the system to allow for acceleration from 0-100mph in less than six seconds.

The 3.8-litre engine produces 727bhp at 7,500rpm and 720Nm of torque from 4,000 rpm, while the electric motor produces 176bhp and maximum torque of 260Nm from zero rpm...

...An IPAS (Instant Power Assist System) button on the steering wheel allows for the full 176bhp from the
electric motor to be instantly available, providing an electric boost like the KERS system on a Formula One car.
