The first concrete details about the Aston Martin Rapide E and its powertrain have been revealed by the British sports car maker.
Developed in conjunction with Williams Advanced Engineering, the Rapide E will feature two rear-mounted electric motors delivering a total of 450kW of power and 950Nm of torque.
A limited-slip differential helps to deliver all that might to ground, while spring and damper rates have been retuned to handle the car's different weight characteristics. The Rapide E rides on specially developed Pirelli P Zero tyres.
The company says it is aiming for a top speed of 250km/h, a 0-60mph (0-97km/h) time of under four seconds, and a 50-70mph (80-113km/h) time of just 1.5 seconds.
The Rapide E's 65kWh battery system consists of 5600 lithium-ion cells located where the regular Rapide's V12 engine, gearbox and fuel tank reside.
According to Aston Martin, the Rapide E will have a driving range of over 320 kilometres under the WLTP regime.
Just 155 Rapide E sedans will be made at the company's new factory St Athan, Wales. The new plant is also responsible for the company's first crossover, the DBX, which is due to go into production from late 2019.
In a prepared statement, Andy Palmer, Aston Martin's CEO, said the Rapide E would fast track the company's EV knowledge, and will "serve as a critical step on our path to re-launching Lagonda as the world’s first zero-emission luxury marque".
The first all-electric Aston Marin Rapide E cars are due to arrive in customer driveways from the fourth quarter of 2019.
