Merged, this set up provides one,055 horsepower and 848 lb-ft of torque, enabling the Speedtail to speed up from -186 mph in just 12.8 seconds. Powering the electric powered motor is a one.6kWh battery pack that “the best energy-to-pounds ratio of any high voltage battery readily available nowadays”. To give you an indication of how McLaren’s battery know-how has state-of-the-art, the Speedtail’s battery energy density is 4 moments greater than the P1.
Also helping the Speedtail realize its blistering performance is an modern battery cooling process and light-weight electrically insulative oil that immediately transfers heat away from the cells. This process is the 1st of its form in a creation street automobile, allowing the cells to run harder and for lengthier.
