This is the 450bhp Kalmar 7-97 E-Volt: the greenest 911 restomod yet?

It’ll also weigh the same as an original 964 Turbo, getting it to 62mph in under four seconds. Price? That’ll be £380,000

Published: 11 Jul 2024

We’ve been feeling a tad bloated of late with the sheer portion of electrified 911s that are being released. But we’ve been forced to make some extra space to sneak in this 964-generation 911 by Kalmar Automotive, dubbed the ‘7-97 E-Volt’.

Before you turn cloak, this one’s different from the rest: it focuses more coherently on using sustainable engineering methods to make this - both literally and figuratively - one of the greenest electric 911s you can purchase.

Kalmar has done that by reusing big sections of the donor cars - including much aluminium and glass - and also creating new ‘plant fibre’ panels for both the interior and exterior. The result? A kerbweight that’s on par with an equivalent ICE-powered 964 Turbo - around 1.3 tonnes.

That low-weight construction has been paired with a repurposed Tesla Model S powertrain. Here, the rear-mounted motor puts out 450bhp and 487lb ft to propel the 7-97 to 62mph in under four seconds. It’s also good for over 200 miles of range thanks to the 63kWh battery pack, with an 80 per cent recharge taking around an hour to complete.

Shaping up to be quite something, this. And that’s before we even get to the really technical stuff: the 7-97 features a new type of air intake for cooling, while the reimagined shell contributes to even slippier aero than the original car. Those aforementioned plant fibre panels even produce 78 per cent lower CO2 emissions during the build than comparable carbon parts.

Wrapping up with a few interior details, Kalmar has thrown in modern air-con, a floor-mounted audio system and Apply CarPlay. You’ll also find grained leather upholstery to warm your bottom, while ‘semi-aniline’ materials have also been used throughout. We don’t know what those are either, don’t worry. Sounds fancy though.

Jan Kalmar, the founder of Kalmar, said: “For us, it had to be more than just dropping an EV motor in a 911. So we looked to see how far we could take its green credentials. Using an existing car as a base is a good start but it had to go further, hence recasting parts, reforming the glass and using technologies such as flax fibres that produce lower CO2 in their manufacture than carbon fibre.

"The donor car for our first 7-97 E-Volt build was an abandoned Porsche 964 with no engine. We have given it a second lease of ‘green’ life.”

Fancy one? That’ll be at least 380,000 of His Majesty’s finest, please.
