Woking brand fastest car makes smart power distribution
The McLaren Speetail is the fastest car from the Woking brand and, after several validated tests to test the top speed of 403 km / h more than 30 times, the British manufacturer decided to make some revelations about the secrets of this speed.
The first revelation, of a more general scope, is the “combination of attributes” of the McLaren hyper-GT hybrid, which cuts through aerodynamics and low-weight construction that privileges carbon fiber and has a “fundamental” exponent in the “system”. motorized motor created for racing. “
This system, as McLaren says, “incorporates pioneering battery technology that sets a new benchmark in hybrid efficiency” translated not only at 403 km / h top speed, but also acceleration power to do just 13 seconds from 0 to 300 km / h.
The M840TQ powertrain comprises a 4.0-liter V8 internal combustion engine and an electric motor that generates a combined power of 1,070 hp and a maximum torque of 1,150 Nm.
In the combustion engine, the technology used in the McLaren P1 (the brand’s first hybrid hypercar) has evolved into a new, lightweight air intake system, better cylinder cooling, and revised piston design – the result is 757 hp and 800 Nm.
The electric motor uses Formula E technology that generates more than 230 kW (308 hp) “, giving the Speedtail the best performance, including cooling and integration, of an electric motor currently used in a production car.” .
McLaren assumes that the power of 8.3 kW / kg reflects “twice the efficiency of a normal sports car” and emphasizes that the energy storage system “is where the Speedtail innovates” using a high-powered cylindrical cell. in one package “being extremely compact and offering the best power-to-weight ratio of any high-voltage battery today.”
The British brand explains that the design and integration of the battery “allows the Speedtail to reach its maximum speed through intelligent power distribution”, achieving a higher and longer-lasting performance for the cells due to the dielectric cooling process that controls its thermal state
The McLaren Speedtail has a limited production of 106 units, priced at around € 2 million, which are already reserved.
