Rapide E: Secrets of First All-Electric Aston Martin


The evolution of the inaugural all-electric car by Aston Martin, also known as the Rapide E, is advancing rapidly with confirmed specific technicalities for the 155-unit limited special edition. Aston Martin has collaborated with WAE (Williams Advanced Engineering), a leading organization in the EV (Electronic Vehicle) technology to initiate a new generation for the manufacturer’s powertrain technology. Further, the collaboration has come in handy to help overcome the technical challenges involved in the motors and battery system packaging.

The engineering team has strived to establish an effective cooling system for the motor and batteries to guarantee dependable performance. Carbon composite elements and lightweight alloys have been utilized to ensure that rigorous weight targets are observed.

Powering the Rapide E

An 800 volt with 65kWh build in capacity electrical battery design will be used to power the Rapide E. It will be fitted with 5600 lithium ion 18650 cylindrical cells which shall be firmly fixed in a designated battery pack. This will also house the fuel tank, gearbox, and the standard 6.0 liter V12.

The two electrical motors fixed at the rear are powered by this battery system which enables them to generate a connected output target of slightly over 610PS and an immense torque of 950Nm.  The WLTP (Worldwide Harmonized Light Vehicle Test Procedure) estimates Rapid E’s scope target to be more than 200 miles. This car model can achieve an 1851, 2 miles per hour charging rate when using an ordinary 400V 50kW charger.

Still, its high voltage battery system can allow for up to 3101, 2 charging rate per hour while utilizing an 800V outlet and conveying more than 100kW. Aston Martin has designed the Rapid E to be a high-performance machine that can be utilized to enhance Milani Exotic Rentals services. Its estimated speed is 155mph complete with a 0-60mph sub-4.0sec time and a 50-70mph time of 15sec.

Absolute Performance

These figures, however, are not only limited to a partial window when the batteries are ultimately charged. Rather, the focus is towards an absolute performance on demand over a huge percentage of the battery charge window state, as would be the case from a traditional in-house combustion-engine vehicle.  This is inclusive of the ability to endure the day to day demands of redundant braking and solid acceleration, as well as the power to drive an entire Nürburgring lap without de-rating the battery.

The Rapid E underbody and exterior have been aerodynamically advanced and finished with modern designed aerodynamic wheels. According to the engineers, the car’s tires are designed to minimize cavity noise while conveying a reduced rolling resistance and a greater power capability. Further, the Rapid E is specially designed to accomplish greater aerodynamic levels, cooling performance, and frictional loss as compared to the Rapid S. This project seeks to improve and maintain the delivery, character, and feel of the Rapid S’s V12- engine.

Finally

The manufacturer will pay special attention to the tuning and evolution of the chassis and electric powertrain while focusing on software integration. Even though the Rapide E will be developed in low volumes, it is currently being exposed to strict Aston Martin’s protocols and a committed Williams Advanced Engineering team collaborating with the manufacturer’s team to ensure that its prototype adheres to the model’s laid down procedures.
