This U.K. shop electrifies classics with precision and sympathy


From the outside, the Porsche 356C looks just as it did when it left the Zuffenhausen factory in 1965. Erwin Komenda’s curves are perfect, its chromework immaculate down to the twin tailpipes protruding from the rear bumper guards. A car restored to the highest quality.

Open the door and the same is true of the cabin. Although the red leather seats, dash, and door cards are perhaps more lavish than when the car was originally delivered, not a thing is out of place. Three pedals and a four-speed manual transmission take the floor.

Open the engine cover, though and you’re in for a big surprise, because the 1.6-liter four-cylinder boxer is long gone. In its stead is an electric motor and ancillary controls units, proudly displayed beneath a plexiglass cover. In the frunk, a battery box takes up all available space behind the spare tire.

The conversion is the work of Electrogenic, a small British firm based near Oxford, and the precision engineering that has gone into it is plain to see. Rather than focus on a limited number of classics to resell as turnkey EVs in the vein of Lunaz or Everrati, Electrogenic has built a modular system that can be applied to almost any car built before 1985.

Having built 14 wildly different vehicles—from VW Karmann Ghias to Triumph Stags, Jaguar E-Types, Morris Minors, Porsches, and early Land Rovers—in the last two years Electrogenic can offer a wide range of power, charging, and performance options, all controlled by the company’s own systems. While every car so far has been different there’s one thing they have in common—each conversion can be reversed and no body or chassis parts are cut away in the process.

Director Steve Drummond explains: “Broadly speaking it’s as follows. If you want to use a manual gearbox, then you need to have a motor that doesn’t rev too high and in terms of what’s available at a reasonable price, then the go-to motor for that is a Hyper Nine. It’s got 235 newton meters [173 lb-ft] of torque, and a maximum 10000 rpm and it runs at low voltage, but you need a gearbox to actually make it into a decent car. As it’s low voltage you can charge it up very quickly on a public charger.

“If you don’t want to keep the manual transmission, then you’re going to have a high-torque motor. So if you look at a Tesla, it’s got a massive motor, which has got really high starting torque, and it revs to 18,000 rpm, so that you get fast acceleration off the block and class top high speed. So they tend to be 350-volt systems. And those motors are more expensive. But then the transmission is cheaper, because you haven’t got to develop a flywheel and clutch to make the gearbox work smoothly. So it’s it swings and roundabouts. Really what it’s about is how do you want your car to drive?”

For the most part Electrogenic’s goal is to retain as much of the original feel of the car as possible, maintaining weight and the distribution thereof as close to standard. Unless the customer has other ideas …

One of the cars currently in the workshop is a TVR Cerbera which the owner wants to be turned into “a track monster with a 15-minute recharge.” There are also a couple of 911s in progress, one of which is a “steampunk version” with a huge amount of power, and a Lotus Eclat which previously had a Rover V-8 in it and will be getting an equally gutsy electric heart.

At the other end of the scale, eight Minis are in production for a London tour company. A mint MGA will soon be running again, nearly silent, three Land Rovers have been built for the Glastonbury estate, and a Morgan and a Citroën DS are already gliding round the English countryside under Electrogenic power.

When it comes to cost, each project is unique. The cheapest full conversion for a Mini is currently in excess of $40,000, while the pretty Porsche 356 ran somewhat higher. One customer specified a particular Swiss drive motor which cost over $30,000 on its own.

There are early signs that Electrogenic’s future-proofing may also prove to be a wise investment. Demonstrator cars have been sold for the price of an equivalent internal combustion–powered model plus the cost of conversion and a little more. The 356 is being offered by its owner at $188,000, or about $67,000 more than its boxer-engined relative.

Whether you consider what is gained by the conversation is worth more than what is lost will be a personal choice of course. In the case of the 356 there’s about 25 percent more power than before and a modest weight penalty of 77 pounds. The rattle and thrum of combustion is replaced by the refined whirr of electric motors and the intricacies of double de-clutching and rev-matching gearshifts are no longer necessary. For some, that’s a luxurious plus; for others, a less-involved driving experience is a less magical one.

The 356 is now, effectively, two cars in one. You can drive it all day long in third gear, where it will pull strongly from a standstill all the way to the legal speed limit, riding a wave of electric torque. Or you can row through the gears and see acceleration to suit a circuit.

In first gear the Electrogenic-converted 356 is seriously rapid off the line, even out-dragging a Taycan until it was time to change up in the company’s tests. The gear changes felt a little ponderous at first but after a few laps of a short track at Bicester Heritage I began to get a feel for it. There’s no one-pedal driving here; the brakes do provide regeneration but only once firmly applied, and though there’s a temptation to heel-and-toe on downshifts, it would bring no benefit. The little Porsche’s agility seems unaffected by the modest increase in weight and while there’s a little more mass over the front axle (now about 40:60 split front to rear) the steering is still light and communicative.

Did I miss the sounds and smells of combustion? Maybe a little, but mostly I came away with the feeling that this is a classic car made even more useable. The 140-or-so-mile range would put a limit on grand road trips, but it could easily be a daily driver, as many of Electrogenic’s conversions already are.

“The big thing about the conversion, apart from being quicker, is that it’s just more relaxed,” says Drummond. “You don’t have to worry too much about being in the right gear, but the gears are nice if you want to drive quickly—they allow you to do that and give you the experience, but you don’t have to stress about it.”
