Performance Hybrids Are The Future

I think we can say we are in good company...

McLaren P1
McLaren has dropped official power figures for the company's upcoming P1. The new hypercar will come packing 903 horsepower and 663 pound-feet of torque from the combination of a 3.8-liter, twin-turbocharged V8 engine and an electric motor. That's right: this sucker is a hybrid. The internal combustion engine features a few tweaks to improve cooling, and McLaren says the block uses a special casting to incorporate the motor. As a result, the P1 features a boost system that can serve up an instantaneous 176.5 horsepower dumped straight to the seven-speed dual clutch transmission. The driver can summon up that grunt on command by pressing the steering-wheel-mounted Instant Power Assist System button.

McLaren has revealed the last piece of the puzzle and announced its tested performance figures. The 100 km/h benchmark (62 mph) falls in "less than three seconds" while the 200 km/h barrier (124 mph) is shattered in "under seven seconds." Lastly, the rear-wheel drive P1 will hit 300 km/h (186 mph) in "no more than 17 seconds" (an impressive 11 seconds faster than its legendary McLaren F1). Those blistering numbers put the P1 among a very small and elite group, with members like Bugatti, Koenigsegg and Hennessey – the fastest road cars on the planet.

The lightweight electric motor, developed by the McLaren Electronics arm of the Group, produces 179PS (176 bhp), and is unique to the McLaren P1™. The motor produces maximum torque of 260Nm instantly from a standstill, greatly increasing the throttle response of the McLaren P1™, and peak combined torque of 900Nm is delivered from just 4,000 rpm. In addition to this, the McLaren-developed 'boost' system, IPAS, provides up to 179PS instantly. The instant response of the electric motor provides a sharper throttle response more associated with a normally aspirated engine, and the significantly enhanced air-charging system enables the McLaren P1™ to have more top-end power – the perfect combination for high performance.

The electric motor is mounted directly onto the engine, and all drive is channelled through the dual-clutch seven-speed gearbox to drive the rear wheels. Thus, the electric motor and 3.8-litre twin-turbo V8 petrol engine work seamlessly together, providing more than just added ultimate power and torque.
