Electrogenic Porsche 911

Other kits volition travel arsenic the institution learns via its bespoke conversions business. The kits can beryllium specified either to clasp the archetypal manual transmission of the donor car, oregon to regenerate the full driveline; they person artillery capacities of betwixt 43- and 93kWh, depending connected the car successful question; and they see DC accelerated charging compatibility astatine up to 50kW.

There are 2 EV kits offered for the Porsche. The little almighty and costly one, arsenic tested here, is designed for a broadly comparable show level arsenic the modular car, and to add astir 120kg to the Porsche’s wide kerbweight; the thought being that you tin acceptable it without needfully uprating the car’s suspension oregon braking. Electrogenic calls this the ‘E62’ kit (215bhp, 229lb ft, circa-5.0-sec to 60mph).

There’s an ‘E62S’ kit arsenic well, which takes powerfulness to 322bhp, but Electrogenic wouldn’t urge fitting it without wider upgrades. Both kits are champion considered constituent parts of wider-ranging restoration programmes that your peculiar fitter mightiness beryllium undertaking connected your car successful parallel.

Electrogenic’s conversion kit includes everything indispensable either to person the 911’s existing instruments for EV-specific accusation (so the translation remains a much subtle one, easier to reverse astatine a aboriginal signifier if necessary) oregon to regenerate them. Our trial car retained its clocks, but repurposed them: truthful the substance level dial would alternatively bespeak remaining artillery capacity, the lipid temp gauge centrifugal somesthesia (it’s water-cooled), the lipid unit gauge artillery regeneration energy, et cetera. I’m not definite you request a centrifugal velocity gauge arsenic good arsenic a speedometer; but I tin spot wherefore 911 owners would privation to support the car’s archetypal clocks.

The Porsche’s wider compartment is untouched prevention for a rotary thrust selector knob wherever the manual displacement lever mightiness be. You get to support the occasional rear seats; but you’ll besides request them for baggage because, up front, the car’s 62kWh thrust artillery wholly fills the ‘frunk’ space.

The value of that artillery battalion rebalances the 911’s famously rearward-biased value distribution, of course: thing which, successful theory, could person a affirmative effect connected 1 oregon 2 of the car’s handling characteristics. For reasons we’ll travel to, though, I’m not truthful definite it really does. But this car surely drives similar a beauteous effectual conversion, good susceptible of satisfying owners who conscionable privation to get their cars retired connected the roadworthy much often - and privation to beryllium capable to proceed to bash truthful successful a motoring satellite that mightiness soon commencement moving beyond fossil fuels. Rather predictably, it’s missing immoderate classical 911 charisma and psyche - but it’s by nary means boring.

Opting to region the car’s aged manual transmission is intelligibly 1 mode successful which you’re besides removing a way to operator engagement; but it besides means you conscionable crook the knob to ‘D’ and compression the accelerator to determination off. The electrical centrifugal offers tons of smooth, accessible low-speed zip and thrust, and much centrifugal vigor regeneration astatine debased speeds than precocious (although Electrogenic tin see manual controls for this if you prefer).

Outright show is strong: peculiarly truthful up to astir 60mph, wherever it puts this ‘964’ connected a par with plentifulness of modern twin-motor EVs. Above 60mph, portion there’s inactive plentifulness of power, you tin consciousness the electrical motor’s powerfulness and torque tailing disconnected a small - but lone astatine speeds astatine which fewer are apt to thrust forty-year-old classical cars. The takeaway present is, for the immense bulk of Porsche owners, an Electrogenic EV conversion volition consciousness similar arsenic ample a step up on accessible gait for their car arsenic is delivered on casual drivability.

The trade-off? That, for audible quality and drama, there’s intelligibly nary examination to beryllium made present to a well-maintained Porsche boxer motor howling distant astatine revs. The electrical centrifugal isn’t silent, nevertheless - and Electrogenic makes nary misguided integer effort either to disguise oregon augment it. The electrical motor is what it is: a small plain and toneless, granted - but acold from level oregon clinical. It’s a constituent part, successful fact, of a driving acquisition that is inactive rather physical, communicative, vivid and ‘analogue’-feeling - adjacent without a petrol engine. 

For starters, putting a quarter-tonne of batteries into the beforehand of a 911 surely gives your forearms a workout. There’s that magnitude of value carried by a beforehand axle which whitethorn not person power-assisted steering to consider. G-Series 911s didn’t; astir 964s did, but successful our trial car the rack’s effectively unassisted successful immoderate case. There’s besides the information that the expanding popularity of ‘the RS look’ connected older 911s makes it rather communal to acceptable wider Fuchs-style alloy wheels to cars similar our trial car, which itself adds steering weight.

Electrogenic tin adhd a column-mounted electromechanical powerfulness steering system as portion of their swap kit; and I’d decidedly person it - due to the fact that without it, your cognition of the other value that has been added volition beryllium each the greater. 120kg isn’t each that much; but, due to the fact that of wherever it sits, its power connected the 911 tin consciousness disproportionate erstwhile you’re moving hard to get the car done a choky corner, oregon if you person to close its cornering cognition rapidly and smoothly astatine faster speeds (there are nary physics stableness immunodeficiency here).

There’s a compromise, too, connected the Porsche’s assemblage control, arsenic our photographs confirm; I'd telephone it significant. though not particularly punitive. This does consciousness similar a 911 that’s approaching the structural limits of the value that its chassis tin bear. There’s a grade of brittleness successful however it rides, and of unchecked rotation and unwelcome inertia successful however it handles erstwhile you analyse the car’s adhesive limits. Neither would halt you from enjoying driving it astatine mundane speeds, though.

With each that accessible torque and nary physics governance, I’d surely privation a mechanical constricted gaffe differential successful the car. As it is, Electrogenic’s kit doesn’t see one, and that means it’s a small excessively casual to rotation up an wrong rear instrumentality erstwhile you’re driving retired of a bend, adjacent successful adust conditions. In the wet, I ideate this could get rather frustrating; not that owners of classical 911s thin to bash a batch of miles successful slippery conditions. The institution says it volition connection an LSD soon, however.

Once it does, determination seems small crushed to question the thoroughness of the engineering that Electrogenic is offering successful this car. If it’s an electrified classical 911 that you want, this 1 seems good executed and thought out. It doesn’t travel escaped of dynamic compromises; but arsenic a ‘plug and play’ solution that uses lone disposable abstraction successful the car, and leaves the chassis uncut and unmolested should you privation to reverse the conversion aboriginal on, it’s a astute mode to experimentation with a caller lease of beingness for your beloved aged Porsche.
