The new McLaren W1 rear-wheel drive supercar is powered by a 1276 horsepower hybrid powertrain combining the all-new 929 horsepower MHP-8 4.0-liter twin-turbo V8 engine with the all-new 347 horsepower E-module (integrating a radial flux electric motor and motor control unit) mated to an 8-speed transmission with E-reverse, coupled with a new hydraulic electronic differential. W1 is capable of zero-emissions driving on electric power alone. Pricing from circa $2.1 million, with the final cost dependent on the level of MSO personalization.
