Few cars have inspired as many reinterpretations as the air-cooled Porsche 911. Two names stand out among the builders who take an original 911 and rebuild it for a new owner: Singer Vehicle Design in Los Angeles and Everrati in the UK and US. Both start with a classic 911, both strip it to the shell, and both deliver a car specified around a single client.
The difference is what goes in the back. Singer refines the air-cooled flat-six to a very high level. Everrati replaces it with an OEM-grade electric powertrain. If you are deciding between the two, that choice shapes almost everything else, from how the car sounds to how often you will use it.
Here is how the two compare.
Who Is Singer Vehicle Design?
Singer was founded in 2009 by Rob Dickinson, former frontman of the British rock band Catherine Wheel. The company restores and reimagines Porsche 911s built on the 964 chassis, produced from 1989 to 1994, and restyles them with carbon fiber bodywork that recalls earlier long-hood 911s.
Singer’s range includes several “studies”:
- Classic Study: The car that made Singer’s name, a restomod 964 with carbon bodywork and a reworked air-cooled engine developed with partners including Cosworth and Williams. Pricing starts above $475,000.
- Dynamics and Lightweighting Study (DLS): Developed with Williams Advanced Engineering, with a 4.0-liter air-cooled flat-six producing 500 hp. Singer announced a run of 75 cars, which sold out.
- Turbo Study: Inspired by the 930 Turbo, with a 3.8-liter twin-turbocharged flat-six producing 450 hp as standard or 510 hp in sports trim, paired with a six-speed manual.
- DLS Turbo: A strictly limited, motorsport-inspired car with a twin-turbo flat-six rated at more than 700 hp.
Singer cars regularly sell at auction for more than $1 million, and a DLS Turbo has been offered with an estimate of $1.5 million to $1.8 million.
Who Is Everrati?
Everrati restores iconic classic cars and converts them to electric power. Each car is rebuilt to concours level first, then fitted with an OEM-grade electric powertrain, and every conversion is designed to be fully reversible.
The electric Porsche 911 range by Everrati covers four models:
- 911 (993) Founders Edition: 567 kW (760 electric hp), 810 Nm of torque, 0 to 60 mph in 3.3 seconds and approximately 200 miles of range.
- 911 (964) RSR: A carbon pack with motorsport aero, up to 500 bhp, 0 to 60 mph in 3.7 seconds and approximately 200 miles of range.
- 911 (964) Signature Wide Body: 500 bhp and 500 Nm, 0 to 60 mph in under 4 seconds and up to 200 miles of range, available as a Coupe, Targa or Cabriolet.
- 911 ST: A lightweight, narrow-body build on a restored steel G-Series shell, with 440 bhp and more than 200 miles of range.
Everrati also builds electric versions of the Mercedes-Benz W113 SL “Pagoda”, Land Rover Series IIA and Defender, Superformance GT40 and Classic Mini.

Design and Heritage
Singer’s design language is its signature. Carbon bodywork, a long-hood look and a high level of detail across the interior make each car instantly recognizable as a Singer. The goal is to build the ideal version of the 911 as Singer sees it.
Everrati takes a different approach to design. The aim is to keep the original 911’s identity intact, whether that is the narrow-body ST, the wide-body 964 Signature and RSR, or the 993. Interiors pair period details such as five-gauge clusters with modern comforts like Apple CarPlay, navigation and upgraded climate control. Our guide to the best Porsche 911 generation to electrify explains how each generation suits an electric build.
Performance and Driving Experience
A Singer is defined by its engine. The high-revving air-cooled flat-six, the induction sound and the manual gearbox are a large part of why owners commission one. For drivers who value that mechanical experience above everything else, it is hard to replace.
An Everrati 911 delivers its performance differently. Instant torque from a standstill gives the 993 Founders Edition a 0 to 60 mph time of 3.3 seconds, while torque-biasing differentials and adjustable suspension keep the car balanced through corners. We keep each car close to its original weight and weight distribution, so it still feels like a 911. Optional Active Sound adds an audible character for owners who want it.
Ownership, Running Costs and Everyday Use
A high-performance air-cooled engine needs regular, specialist servicing, and like any combustion classic it is affected by fuel availability and emissions rules over time.
An electric 911 removes oil changes, ignition tuning and many of the wear items of an aging flat-six. AC and DC fast charging and approximately 200 miles of range make it practical for regular driving, and zero tailpipe emissions mean it can enter low-emission zones that restrict older cars.

Personalization and Commissioning
Both companies build to order, and both put the client at the center of the specification. Singer works through its design team and a dedicated Special Wishes program for more unusual requests.
At Everrati, every commission is specified through Artisan by Everrati, covering body style, battery capacity, powertrain tuning, interior materials and livery. That specification is documented and stays with the car to support its provenance. You can follow each stage of a build on The Process.
Value and Long-Term Ownership
Singer cars have built a strong collector market, with auction results that often exceed their original commission price. That track record is a key part of their appeal.
Everrati’s case rests on reversibility. Because the original components can be retained, a future owner can return the car to its original configuration, which protects the car’s heritage and keeps its options open. Our article on restoration vs recreation covers why this matters to collectors.
Which Should You Choose?
A Singer may suit you if the sound and feel of an air-cooled flat-six is central to your idea of a 911, you want Singer’s distinctive design language, and you plan to drive the car mainly for occasional, special trips.
An Everrati may suit you if you want classic 911 design with instant electric performance, lower running demands, zero tailpipe emissions and a car you can use regularly, with a conversion that can be reversed in the future.
Both builders share a respect for the original 911. The choice comes down to whether you want that car to keep its combustion engine or move to electric power. For more comparisons, see Lunaz vs Everrati, Rimac vs Everrati, Electrogenic vs Everrati and Boxster EV vs Everrati 911.
