Put together, this set up makes 1,055 horsepower and 848 lb-ft of torque, enabling the Speedtail to accelerate from -186 mph in just 12.8 seconds. Powering the electric motor is a 1.6kWh battery pack that “the best energy-to-bodyweight ratio of any large voltage battery obtainable currently”. To give you an indicator of how McLaren’s battery engineering has state-of-the-art, the Speedtail’s battery energy density is four situations increased than the P1.
Also aiding the Speedtail accomplish its blistering general performance is an progressive battery cooling system and light-weight electrically insulative oil that swiftly transfers heat absent from the cells. This system is the very first of its kind in a production road car, making it possible for the cells to run more challenging and for extended.
