A re-designed underfloor streamlines airflow from the front splitter right the way through to Rapide E’s new larger rear diffuser – a feature that is now wholly dedicated to aero efficiency due to the removal of the exhaust system required before. The model’s forged aluminium aerodynamic wheels – shod with bespoke low rolling-resistance Pirelli P-Zero tyres – have also been re-designed to give greater efficiency, without compromising brake cooling capability. The sum of these changes gives Rapide E’s aerodynamic package an 8% improvement over the previous internal combustion model.
Inside and out, Rapide E is equipped with the materials and technology befitting of the marque’s first EV model. Gone are the analogue displays of the past. A 10” digital display now sits in their place, delivering all key information to the driver while on the move, including the battery’s state of charge, current motor power levels, regenerative performance and a real-time energy consumption meter. Swathes of carbon fibre have been deployed throughout, assisting in delivering the strict weight targets set by Aston Martin’s engineering team from the outset.
Extending the experience beyond the car, a dedicated app allows key information from the car to be remotely monitored. This powerful dashboard displays remaining range, battery status, and time to charge, as well as allowing navigation destinations to be sent from the app to the car for easy route planning. The car’s parking spot can also be seen via the app, with walking directions provided to help re-locate it in busy locations. Finally, the health and status of Rapide E can also be tracked from the app, providing reminders such as when a key service is due.
Throughout the development process, the combined AML/WAE engineering team first focussed their efforts on finding packaging solutions for the battery system and motors within the Rapide’s architecture before working to achieve effective cooling of the batteries and motors.
Rapide E is powered by an 800V electrical architecture battery – encased in carbon fibre and Kevlar casing – with a 65kWh installed capacity using over 5600 lithium-ion 18650 format cylindrical cells. This bespoke battery pack lies where the original 6.0-litre V12, gearbox and fuel tank were located, with the 800V system allowing for more efficient charging and greatly improved thermal characteristics over existing electrical architectures. This battery system powers two rear mounted electric motors producing a combined target output of just over 610PS and a colossal 950Nm of torque.
Rapide E’s range is over 200 miles under the Worldwide Harmonised Light Vehicle Test Procedure (WLTP), while the model is capable of charging at a rate of 1851,2 miles of range per hour using a typical 400V 50kW charger. However, the car’s 800V high-voltage battery system enables faster charging of 3101,2 miles of range per hour, using an 800V outlet delivering 100kW or higher. For destination charging, the car also features an industry-leading high-power AC on-board charger capable of recharging the battery in as little as 3 hours.
Top speed for Rapide E is 155mph, with a sub-4.0 second 0-60mph time and a 50-70mph time of just 1.5 seconds. These figures are not restricted to a narrow window of battery charge or climatic conditions, instead, thanks to the cutting-edge 800V architecture, the Rapide E will deliver its performance in a consistent and repeatable way as would be expected from a traditional Aston Martin product. This includes the ability to drive a full lap of the Nürburgring with no performance derating of the battery or the motors.
Rapide E also enhances the feel, character and delivery of the V12-engined recently acclaimed Rapide AMR, thanks to careful attention paid to the tuning of both the electric powertrain and the chassis across three driving modes – GT, Sport and Sport + – which are selected for both the powertrain and handling. The rear-wheel drive Rapide E’s twin electric motors drive through a Limited-Slip Differential, which combined with a revised spring and damper rates, ensures the pure handling characteristics of the petrol-powered Rapide AMR are retained.
