We drive a Porsche 356 C converted to pure electric power by Electrogenic.

For many enthusiasts, the idea of owning a classic car is highly appealing, but the reality can be very different. While classics are often stunningly beautiful to look at and feel more special than modern models, running a vehicle that’s several decades old can prove to be an expensive and time-consuming challenge.

One straightforward solution is being offered by manufacturers and third-party firms: to futureproof classic cars by ripping out their petrol engines and installing electric motors in their place. To find out how this works and what the end result is like, we went to UK-based Electrogenic which is leading the way in classic-car conversions.

Electrogenic was founded in 2018 by Steve Drummond and Ian Newstead. Steve is a mechanical engineer whose background is in the energy industry, through which he became an advocate of renewable energy. For him, converting classics to electric power is a way to help the car industry go green.

Ian began his career as an RAF radar technician, before switching to cars when he got a job with racing team Norman Abbott Engineering. He opened his own garage in 1995, specialising in the restoration of classic air-cooled Volkswagens and Porsches. The idea to start working on EVs came from Ian’s daughter, he told us.

“I was working on a car, but I suffer badly from allergies and one of the worst things for me is unburnt fuel; it makes my eyes itch and run,” Ian explained. “My daughter looked at me as if I was a monster and said: ‘Dad, you’ve got to stop doing this. Why not work on electric cars instead?’”

Ian and Steve already knew each other through the motor trade and, when discussing a van the two were haggling over, Ian suggested that it would be better with an electric motor rather than its existing engine.

“We did some research, including a trip to California,” Steve told us. “We decided that, for the first time ever, it was possible to make an electric car worth owning. Four years later, here we are.”

Electrogenic will now take any car and convert it from petrol or diesel power to electric, taking into account whatever specifications the customer desires. The process is fully reversible, too, but if you do change your mind, you’ll have to find another firm to restore the original motor, because Electrogenic doesn’t undo its own work.

“We don’t want to lose these cars,” Ian told us. “The last thing we want is to see them disappear or end up in museums. We want to see them still driving on the road and this enables them to do that.”

It’s not just about futureproofing, though, as Steve explained: “Most sixties and seventies cars are actually quite difficult and unpleasant to drive. They’re slow, they struggle to pull out at junctions, et cetera.

“If you make these cars able to keep up with modern traffic, though, they become something that’s fun to drive instead of something that’s a bit scary.”

Steve and Ian weren’t content to let us take their word for this, they wanted us to try it out for ourselves. So, we headed down the road from Electrogenic’s Kidlington headquarters to the test track at Bicester Heritage, where we were handed the keys to a finished customer car.

The model in question was a 1964 Porsche 356 C. Originally, this rear-engined coupe had come with a 1.6-litre flat-four petrol engine, producing around 70kW, coupled to a four-speed manual gearbox. This enabled 0-100km/h in 10.3 seconds and a top speed of 185km/h.

In a move that may outrage purists, though, Electrogenic changed nearly all of these details. In the car we tried, there was no trace of the 1.6-litre engine. In its place, we found a Netgain Hyper9HV air-cooled electric motor, which runs at 144V and draws power from a 36kWh battery.

As a result, the Electrogenic 356 C makes 80kW and 0-100km/h only takes around seven seconds. What’s more, the top speed is increased to 200km/h and there’s an impressive 225km of range, provided the car is cruising rather than being driven on the limit. The 356 can also be fully recharged in just under two and a half hours.

There’s one key original feature that’s been left in the car, however, that separates this electric vehicle from anything you can buy from a modern manufacturer’s showroom: that four-speed manual gearbox we mentioned is still in place, coupled with a new lightweight clutch.

The feeling is an odd one. It’s much easier to change gear in the Electrogenic 356 than it is in an unaltered classic car, but the lightness of the clutch pedal and gearlever, combined with the lack of an exhaust note, is quite eerie and takes some getting used to. It does add some enjoyment to the EV driving experience, though, and while the 356 is no Tesla Model S or Porsche Taycan, there’s still a decent punch of acceleration when you hit the throttle.

It’s fair to say this conversion wouldn’t be a viable option for classic-car owners wanting to preserve the sound and feel of their cars, but if you want the looks without the hassle, then it’s hard to fault Electrogenic’s work.

Electrogenic has a range of options depending on customer demands, but the owner of the 356 we tested had paid somewhere in the region of £40,000 (AUD$68,000) for the EV conversion.

Explaining the different options Electrogenic offers, Steve said: “The first question is do you want to drive it using a gearbox or not? A lot of our customers, like the owner of the 356, like to have an active driving experience. It’s an old car and they want to drive it in a manner similar to how it was driven originally, hence a motor with a gearbox.

“The other thing is how many batteries to put in. The conversation we generally have with customers is don’t try and fill the car up with batteries because you will change the way it handles. It’s much better to ease back on the number of batteries and have a slightly lower range.”
