La quattro porte a batteria ha 612 CV e 322 km di autonomia, ma ne saranno prodotti solo 155 esemplari
Il Salone di Shanghai 2019 si sta rivelando davvero ricco di sorprese e novità importanti e fra queste si segnala anche l'Aston Martin Rapide E, prima supercar elettrica della storica Casa britannica ad essere prodotta in serie.
Il prezzo è ancora tenuto segreto e riservato a chi ordinerà uno dei 155 esemplari previsti per la produzione in piccola serie. In pratica si tratta di una prova generale per il lancio del rinnovato marchio Lagonda che produrrà solo auto elettriche.
612 CV elettrici
Le forme sono quelle già note della quattro porte Rapide, ma sotto il cofano della Rapide E non nasconde il classico 6.0 V12 a benzina; a spingere in avanti con forza la super GT elettrica inglese ci pensano due motori elettrici montati al retrotreno, mentre davanti trova posto il pacco batterie composto da 5.600 celle agli ioni di litio per un totale di 65 kWh di capacità.
Il sistema elettrico a 800 volt, come quello che sarà sulla Porsche Taycan e sull'Audi e-tron GT, alimenta i motori che assieme sviluppano 612 CV e 950 Nm, ben più del noto V12.
12 minuti di ricarica per fare 100 km
Per accelerare da 0 a 100 km/h la nuova Aston Martin Rapide E impiega appena 4,2 secondi, mentre la velocità massima è limitata elettronicamente a 250 km/h. L'autonomia dichiarata è di circa 322 km secondo il ciclo di omologazione WLTP e la ricarica può essere fatta a diverse velocità: con la ricarica domestica a corrente alternata servono quasi tre ore per un pieno elettrico grazie al potente caricatore di bordo, mentre il colelgamento ad una colonnina fast a corrente continua da 50 kW garantisce la ricarica completa in poco più di un'ora.
E' possibile effettuare anche ricariche ultra fast a corrente continua da postazioni da 100 kW e oltre (a 800 volt) per garantirsi 100 km di autonomia aggiuntiva in 12 minuti.
Le modifiche interne ed esterne che distinguono la Rapide E dalle altre Aston Martin Rapide includono uno schermo da 10" al posto della strumentazione tradizionale e un fondo ridisegnato per ottimizzare i flussi d'aria dal frontale fino al diffusore in coda.
I cerchi in lega dal disegno aerodinamico migliorano anche il raffreddamento dei freni e anche il frontale è stato affinato per fendere meglio l'aria.

16 April 2019, Shanghai, China: Aston Martin Lagonda has revealed the final production-ready iteration of its first all-electric production car, with the spectacular Rapide E making its world debut at China’s Auto Shanghai motor show.
Unveiled by Aston Martin Executive Vice President & Chief Creative Officer, Marek Reichman, Rapide E is a pivotal model for the luxury marque. Following the success of previous special-edition models, including Aston Martin Vulcan, the Vanquish Zagato family and DB4 GT Continuation, Rapide E continues to deliver a superior level of performance, craftmanship and exclusivity, while also propelling Aston Martin into the all-electric realm.
The first car to be built at Aston Martin’s state-of-the-art St Athan production facility – the brand’s Home of Electrification – Rapide E represents a pioneering first step towards achieving the company’s wider electrification strategy and the successful fruition of Lagonda – the world’s first zero-emission luxury brand. A special edition with a production run strictly limited to 155 units, Rapide E has been developed in collaboration with Williams Advanced Engineering (WAE).
Shown for the first time here in Shanghai today, Aston Martin’s design and engineering teams have worked in partnership to extract the optimal aerodynamic performance available from the Rapide’s elegant form. Traditional metal vanes give way to a striking honeycomb front grille. With lower cooling requirements demanded of the EV powertrain, Aston Martin’s aerodynamic engineers have been given the freedom to optimize the aperture of the frontal area, minimising airflow through the car’s body, improving the car’s aerodynamic efficiency and increasing range as a result.
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.
Speaking ahead of Rapide E’s Shanghai debut, Dr Andy Palmer, President and Group CEO, Aston Martin Lagonda, commented: “Unveiling the Rapide E will be a huge moment for Aston Martin. As our first all-electric production car, it is a truly historic step. One that signals Aston Martin is prepared for the huge challenge of an environmentally responsible and sustainable future. As a car company we cannot afford to passively allow that future to come to us; we have to actively chase it. Only by doing this can we learn and prepare, but also preserve those things we love as drivers and car enthusiasts. That’s why it was so important to me that in embracing EV technology we should not let go of those unique qualities that define an Aston Martin. I believe Rapide E embodies that desire and paves the way for a hugely exciting future.”
Rapide E is available to order now, with prices available on application.
