September is turning out to be a month focusing on electric vehicles. Already, Mercedes-Benz has pulled the cover off the EQC and Audi is planning to reveal the E-Tron crossover next week. Now Aston Martin has announced official specifications for its first electric vehicle, the Rapide E.
The model being worked on with Williams Advanced Engineering will use two electric motors on the rear axle to deliver 602 horsepower and 700 pound-feet of torque. 0-60 mph is said to take under 4 seconds and the Rapide E can hit a top speed of 155 mph. A 65-kwh lithium-ion battery pack is estimated to provide a range of over 200 miles on the new WTLP test cycle - somewhat disappointing when compared to the likes of the Tesla Model S 75D which offers a range of 259 miles. Using a 50kW charger, the Rapide E can get a 150 mile charge in just an hour. There will also be a 100kW charger that provides a charge of 5 miles per minute.
The Rapide E's exterior and underbody has been tweaked to improve aerodynamics. This includes a unique design for the wheels. The Pirelli P Zero tires feature sound deadening to help make the vehicle as quiet as possible.
Aston is only planning to build 155 Rapide Es when production kicks off late next year. The model will be used as a rolling testbed for future Aston and Lagonda electric vehicles.
"As our first all-electric production model, Rapide E will fast-track our knowledge and help us ensure the character and high-performance capabilities of our future EV models and enhance the unique qualities found in all Aston Martins as we know them today. Rapide E will also serve as a critical step on our path to re-launching Lagonda as the world’s first zero-emission luxury marque," said Andy Palmer, CEO of Aston Martin.

Rapide E: Secrets of First All-Electric Aston Martin Revealed
- Rapide E to be Aston Martin’s first Battery Electric Vehicle (BEV)
- Product name confirmed as ‘Rapide E’
- Aston Martin developing Rapide E with Williams Advanced Engineering
- Production run of 155 units
- Twin electric motors to produce over 610PS and 950Nm of torque creating most powerful Rapide model
- Features innovative 800V battery system; DC/DC converter facilitates fast charging, even on 400V network
- Cars will be built in dedicated facility at Aston Martin’s St. Athan site
- First customer deliveries scheduled for Q4 2019
12 September 2018, Millbrook, England: With development of Aston Martin’s first all-electric production car – the Rapide E – progressing apace, the luxury British marque has today confirmed a raft of technical details for the strictly limited 155-unit special edition.
Working closely with Williams Advanced Engineering (WAE) as its development partner, Aston Martin has utilised the hugely successful leader in Electric Vehicle (EV) technology to kickstart a new era for Aston Martin’s powertrain technology and overcome the technical challenges associated with packaging the battery system and motors within the space available.
Throughout the development process, the engineering team have focused on achieving effective cooling of the batteries and motor to ensure consistent performance, while strict weight targets have been stringently observed using lightweight alloys and carbon composite materials.
Rapide E will be powered by an 800V battery electrical architecture with 65kWh installed capacity using over 5600 lithium ion 18650 format cylindrical cells. These are mounted in a bespoke battery pack where the original 6.0-litre V12, its gearbox and fuel tank were located. 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 target 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.
Being an Aston Martin, the Rapide E is being developed with a high-performance objective. Projected top speed for the Rapide E is 155mph, with a sub-4.0sec 0-60mph time and a 50-70mph time of just 1.5sec. It’s important to stress that these figures are not restricted to a narrow window only when the batteries are fully-charged. Instead the target is for maximum performance on-demand throughout majority of the battery state of charge window, as would be expected from a conventional internal combustion-engined car. This includes the ability to drive a full lap of the Nürburgring with absolutely no derating of the battery and the ability to cope with the daily demands of repeated hard acceleration and braking.
The car’s exterior and underbody has also been aerodynamically optimised and complemented with newly-designed aerodynamic wheels. Shod with Pirelli P-Zero low rolling-resistance tyres featuring noise-cancelling foam, Rapide E aims to achieve higher levels of aerodynamic, frictional losses and cooling performance over the standard Rapide S.
It has also been an objective of the project to retain and enhance the feel, character and delivery of the V12-engined Rapide S. To this end, careful attention will be paid to the development and tuning of both the electric powertrain and the chassis, with particular focus applied to software integration. The rear-wheel drive Rapide E’s twin electric motors will drive through a Limited-Slip Differential, which combined with revised spring and damper rates ensures the pure handling characteristics for which the petrol-powered Rapide S is already renowned.
Though the Rapide E will be built in low volumes, it is being subjected to Aston Martin’s stringent and exhaustive testing protocols, with the dedicated WAE team working closely alongside Aston Martin personnel to ensure every aspect of the prototype test programme follows the marque’s established procedures. Uniquely, customers will be an extended part of the ongoing Rapide E programme, with their comments and driving experiences providing an invaluable stream of feedback that will help shape and improve future Aston Martin EVs.
In addition to WAE, the Rapide E programme enjoys the support of other technical partners including Hyperbat Limited – a new joint venture company between Williams Advanced Engineering and Unipart Manufacturing Group – as the battery manufacturer, Integral Powertrain Technologies for the electric motors, Xtrac for the transmission and the H1PERBAT project consortium with grant funding from the Advanced Propulsion Centre.
Speaking of the Rapide E programme, Andy Palmer, CEO Aston Martin, commented: “Environmental responsibility and sustainability is a global challenge faced by us all. As a career automotive engineer, I’m proud that the car industry is leading the way in finding long-term solutions and reducing harmful emissions. As Aston Martin’s CEO, I take particular satisfaction working with Williams Advanced Engineering and our other associated technology partners to bring Rapide E to reality. As our first all-electric production model, Rapide E will fast-track our knowledge and help us ensure the character and high-performance capabilities of our future EV models and enhance the unique qualities found in all Aston Martins as we know them today. Rapide E will also serve as a critical step on our path to re-launching Lagonda as the world’s first zero-emission luxury marque”.
Rapide E will be built at the upcoming St. Athan production facility, announced as the future ‘Home of Electrification’ for both the Aston Martin and Lagonda brands. Aston Martin is accepting expressions of interest via its global dealership network, with pricing available on application. Customer deliveries are set for Q4 2019.
