Everrati Automotive has unveiled a flagship 500 horsepower Signature wide body model based on a restored 1991 Porsche 964 (911). The car features carbon fibre body elements and a state-of-the-art EV powertrain allowing sub-4-second 0-62mph (0-100km/h) acceleration and a driving range of more than 150 miles (241km), subject to driving style. Everrati said that following an intensive test and development programme, the model will be finished to concours standards and offered to customers as part of the company’s extensive portfolio of restored, remastered, and electrified automotive “icons”.
“When we launched Everrati in 2019, it was our mission to create the most desirable, technically advanced, sustainable, zero-emission iconic cars in the world,” said Justin Lunny, Founder & CEO of Everrati. “To fulfil that vision, and to provide discerning customers with a peerless product engineered with industry-leading technology, rigour, and attention to detail, we assembled an elite engineering team from OEM, supercar, motorsport, aerospace, and EV technology backgrounds.
“We believe that it is the very DNA of a car that makes it iconic and that such cars must be preserved for future generations – not be placed in a museum, but to drive. We take some of the world’s most beautiful and seminal cars, restore and re-engineer them, always operating with full respect for the brands that created them. Using modern engineering techniques and integrating advanced EV powertrains, we further enhance each car’s performance, yet ensuring they have a similar driving feel with weight distribution – and overall weight – mirroring that of the original, enabling automotive icons like the Porsche 964 to be reborn for the coming age of zero-emission mobility, yet with soul intact.”
The Signature began with a solid, accident-free example of a Porsche 964, with the first stage of the car’s metamorphosis being a disassembly to a bare monocoque chassis. All bodywork, powertrain and interior components were removed from the car.
“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 founder and COO, who previously held senior roles with Daimler and 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.”
The monocoque chassis is water-blasted to its bare zinc coating and inspected and treated for rust prevention, if required. To ensure adherence to Everrati’s core pillars of safety and structural integrity, the monocoque is seam-welded, strengthened, and refabricated to better-than-new standards.
To create the wide body, Everrati replaces the steel front and rear guards and bonnet with custom produced carbon fibre parts. The same material is used for the doors, although these are reinforced with high strength steel to retain side impact protection. A carbon fibre 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 wide body items, with RS Cup air vents added.
“We work in close collaboration with leading Porsche 911 specialists and carbon fibre manufacturers in the UK and use only exceptionally strong and lightweight carbon fibre components manufactured to motorsport specification in an aerospace environment,” said Williams. “The carbon fibre bodywork is constructed using a premium resin-infused closed mould process to ensure very high quality and strength coupled with low weight. Then we apply world-class body preparation and painting processes to produce flawless paint finishes.”
Everrati said that thanks to this high-tech approach to weight saving, the Signature wide body weighs less than the original Porsche 964 coupe.
A key part of the restoration and re-engineering process is the integration of the car’s electric propulsion system. “We install a state-of-the-art EV powertrain, which has its power delivery optimised specifically for the Signature wide body and is coupled to a 53kWh battery pack and battery management system,” said Everrati Director of Engineering, Mike Kerr, who previously held senior roles with Lotus and McLaren.
“One of the values that attracted me to Everrati was the obsessive level of detail the company goes to ensure that its EV technology is integrated sympathetically, and in a manner totally in keeping with the true spirit of the original car and its manufacturer,” continues Kerr. “But there’s more to it than that. The transformation to electric power also involves the optimisation of weight distribution, chassis response and safety to enhance the performance of the original, reinvigorating its character and soul.”
Sending 500hp to the rear wheels, the new car has more than double the power output of an original 1990s Porsche 964. With 500 Nm delivered instantly, the car can accelerate to 62mph (100km/h) in less than four seconds.
The range is rated at 150-plus miles (241-plus km), dependant on driving style. Using a DC fast charger, Everrati said the battery can be replenished from 10 per cent to 100 per cent in less than an hour, at the cost of just £8.21 (A$15.06).
Former British Touring Car Champion and Porsche Carrera Cup Driver’s Champion, Tim Harvey, has supported much of the car’s development. With 35 wins and more than 150 podiums at the wheel of a 911, Harvey is one of the most successful Porsche racers and relishes his role as Everrati test driver.
“The latest car is a fantastic project to be involved with. I have owned and raced many Porsches and having the chance to be involved with the rebirth of this true icon is a privilege,” said Harvey. “The Signature wide body has the essence of an iconic 911, in terms of its rear-biased weight distribution and the ‘feel’ of its controls, brought right up to date thanks to the incredible performance from its electric powertrain. In this way, it is great to think that future generations will still be able to enjoy the 964 in an era of zero-emission mobility.”
Everrati retains the car’s aluminium rear trailing suspension arms, which are refurbished to new, with all bushes and drop-links fully uprated. Customers are offered a choice of two suspensions settings. The ‘standard’ suspension features fully adjustable motorsport-grade coil-over spring and damper units. Everrati said this provides a compliant, quiet, and comfortable ride on the road while still offering superb control during more dynamic driving. The optional, fully adjustable suspension package features adaptive dampers by Tractive, providing even more sporting focussed levels of control and driver feedback. It features a fully programmable and customisable five-driver-mode set-up, controlled from within the cockpit via a touch screen.
The car’s EV powertrain provides regenerative braking when the driver lifts off the accelerator pedal. Drivers can adjust the level of regenerative braking force available to enable one-pedal driving. The uprated mechanical braking system features fully renewed Brembo Porsche callipers with new drilled, ventilated discs all around. An optional, more powerful braking system is offered, featuring larger Brembo callipers front and rear.
A range of 17” and 18” wheels and colour finishes are available to suit customer requirements.
The cabin can be personalised to customers’ individual tastes in numerous ways, thanks to a wide range of optional materials and fittings. Everrati re-instals original Porsche seats, which are significantly enhanced for comfort and replicate the look of the original RS Touring Seats. All have four-way electrical adjustment and manual recline and tilt functions. Optional Carbon RS seats provide more sporting ambience. Upholstery can be optioned in leather, alcantara, or other materials and in a wide choice of colours and optional finishes and textures.
Further highlights of the interior include the installation of a custom-designed heating and air conditioning system. In addition, a modern Porsche Classic Communications Management with full touch screen navigation, DAB+, Bluetooth, Apple Car Play is added. 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.
Over the coming months, the Signature wide body will continue to undergo its full development programme. A small number of Signature commissions are available to order now for delivery in late 2021. Prices for each commission begin at £250,000 (A$458,550), plus relevant taxes, based on a customer-supplied donor car.
