Everrati Automotive Limited, a British company specialising in converting iconic cars to run with electric powertrains, has unveiled its new flagship, the 500-bhp Signature. It is developed from a fully restored 1991 Porsche 911 964 and has been given widebody treatment with carbonfibre elements.
The Signature joins other Everrati electrified models such as the Mercedes-Benz SL Pagoda (its first conversion in 2019), along with 911 (964) Coupe and Targa models, a 911 (964) Gulf Signature Edition, and a Land Rover Series IIA.
Carbonfibre parts, including roof
To create the wide body, Everrati replaced the steel front and rear wings and bonnet with custom produced carbonfibre parts. The same material is also used for the doors, although these are reinforced with high-strength steel to retain side impact protection.
A carbonfibre roof is offered, along with the choice of a steel item for customers who wish to retain a sunroof where fitted to their car. The front and rear bumpers are refitted with genuine Porsche widebody items, to which RS Cup air vents are added. Thanks to this high-tech and meticulous approach to weight saving, the Signature widebody weighs less than the original 911 (964) Coupe.
A key part of the meticulous, sympathetic restoration and re-engineering process is the integration of the car’s new, sustainable-focussed heart – the electric propulsion system. “We install a state-of-the-art EV powertrain, which has its power delivery optimised specifically for the Signature widebody and is coupled to a 53-kWh battery pack and battery management system,” explained Everrati Director of Engineering, Mike Kerr.
500 bhp and 500 Nm
Sending 500 bhp to the rear wheels, the Signature widebody has more than double the power output of an original 1990s Porsche 964. With 500 Nm available from almost standstill, the car can accelerate to 100 km/h in less than 4 seconds and depending on driving style, travel for 240+ kms on a full charge, it is claimed. Recharging the battery pack to full from 10% is said to be possible in less than an hour with a DC fast charger.
Everrati retains the car’s aluminium rear trailing suspension arms, refurbished to new, with all bushes and drop-links fully uprated. Customers are offered a choice of two suspension settings: standard suspension with fully adjustable motorsport-grade coil-over spring/damper units, and a fully adjustable package with adaptive dampers that are fully programmable from within the cockpit via a touchscreen.
Brembo stopping power
The EV powertrain provides regenerative braking when the driver lifts off the accelerator pedal, capturing energy that would be wasted. The driver can adjust the level of regenerative braking force available to enable one-pedal driving. The uprated mechanical braking system features fully renewed Brembo Porsche calipers with new drilled, ventilated discs all around. An optional, even more powerful braking system is available with larger Brembo calipers front and rear.
Customised and original
As for the interior, the cabin can be personalised to customers’ individual tastes in numerous ways, thanks to a wide range of optional materials and fittings. The original Porsche seats are fitted, which are significantly enhanced for comfort and replicate the look of the original RS Touring Seats, and optional Carbon RS seats provide an even more sporting ambience. The upholstery can be in leather, alcantara, or other materials and in a wide choice of colours and optional finishes and textures.
Customers can also have custom-designed heating and air conditioning system and add a modern Porsche Classic Communications Management with full touchscreen navigation, DAB+, Bluetooth, and Apple Car Play. All of the car’s traditional gauges are replaced with Porsche-inspired EV gauges, and as with the internal combustion engine and transmission components, the original gauges can be retained for the customer on request.
Reversible engineering
“At Everrati, it is sacrosanct that all engineering is reversible, should current or future owners want to revert back to the car’s factory specification,” said Nick Williams, Everrati’s Founder and COO, who previously held senior roles with Daimler and the Volkswagen Group. “If customers wish, the car’s original internal combustion engine and transmission can be refurbished and placed in storage, or even incorporated into a piece of art, such as a glass gable or Perspex box. Whatever the customer can imagine, we will do our utmost to make it a reality.”
Over the coming months, the Signature widebody will continue to undergo its full development programme. For those who are interested in acquiring one, prices start at £250,000 (about RM1.47 million), based on a customer-supplied donor car.
