    Aston Martin Spills More Details On Rapide E

      Reveals info on the powertrain and range


    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.

    One

    The rest will be mock-ups with smallblock Chevy engines, with their sweet music dubbed out.  That leaves one for the inevitable James Bond nerd with more money than brains.

    • Toyota has penetration in a lot of global markets.  But just looking in the USA, the Rav4 is the #4 selling vehicle in the country.  And when you go by segments, the Camry is the best selling car, Rav4 the best selling SUV, the Highlander probably is the #1 selling 3 row SUV, if it isn't it is close, the Civic beats the Corolla, that is an area Toyota needs to improve but the Corolla Cross is now there, so maybe that is their answer.   But then Toyota has the #1 selling mid-size truck, the 4Runner still sells decent despite being ancient.  The Lexus RX is the best selling luxury SUV, the ES350 still sells pretty strong.     Toyota is strong in a lot of key segments, and much of the competition is giving up on some of those segments.  Mazda dropped the 6 and the CX-3, Ford has dropped all cars but Mustang, and they are dropping Ecosport in 6 months, GM seems to be dropping every car they have at the end of the life cycle except for Corvette.  I feel like a lot of car companies are giving up on segments and making Toyota's job even easier.
    • Is this the new Z06?  It appears to be.  It is said that General Motors posted this on Instagram today.  https://www.roadandtrack.com/news/a37755096/this-is-the-c8-corvette-z06-undisguised/     I like it. I like it better than the Stingray.  I dont necessarily like this colour though, but I think if this is the new Z06, then its a smashingly good looking C8.  I want to see how it looks in yellow with C8R cues on it.  Interesting to see how much more aggressive the Z07 package would be on this as I dont see an aggressive rear spoiler nor aero canards and aero stuff in the front.  Rear diffuser in the back? Center exhaust? Which Z06 will have all that? Is this the "base" Z06? Lots of questions still need to be answered and the questions above are still just about the exterior design and engineering choices and specs.  Engine choice is still a mystery.   And with the C8 side air vents being what they are, and how they and up helping gulp in more air for the C8R and now with this reveal,  one visual I enjoy and appreciate very much on the Z06 is this cue:   Very vintage American muscle car what Chevy designers did there.  👍  Very keeping the original inspiration of shark colour and loosely based looks.  🤙      
    • 😅 How many people are replacing a $24K vehicle with a $75K vehicle??? Not a significant volume, without a doubt.
    • Being the sales leader in any market makes you a target for all other competitors.  Now Toyota faces what GM had to deal with for nearly a century: everyone is nipping at its heels.  The leader makes a few wrong decisions judging the future of the marketplace and everyone else pounces on their mistakes one way or another.  Toyota can probably shift from hydrogen to full EV since they have their hybrid lines have taught them a whole lot about the technology and what it takes to deliver.  This is NOT GM of the 1970s and 1980s, where GM was struggling to contain and defeat Toyota and Honda in competition for Boomer buyers.  GM lost a LOT of market share from 1968-2009 (about 1 percentage point per year), which allowed Toyota to surpass them on the sales sheets.  EVs to the left, with Hyundai/KIA to the right, Toyota looks like they might be squeezed if they are not careful. If Toyota's days at number 1 are numbered, that may not be a bad thing.  If they lost the prize of being the number one sales leader, that would allow Toyota to focus on making the best vehicles, not just merely moving the metal.  Is GM in better shape now, or in 2004 when they ended Oldsmobile, with the last one off the assembly line as an Alero?  GM has not been in as good of shape in at least 15 years or more than right now.  And some of that is AFTER it lost the #1 title to Toyota.  Toyota fears being surpassed by cheaper competitors AND better products that fit tomorrow's markets better than what is currently on offer.  Imagine if FORD or GM had a true Tacoma killer.  Imagine if FORD or GM had an EV that renders the Prius line completely obsolete, at prices Toyota cannot or will not match.  New competitors will give Toyota executives some sleepless nights. In a competitive environment, NO LEAD is safe from being surpassed.  Ever.  Just ask GM.
