A Classic Mercedes Roadster Is Going Electric in a New Partnership

Hemmels, a Cardiff, Wales-based company that rebuilds Mercedes-Benz SLs, will soon offer an electric drivetrain for the W113 “Pagoda” models to the tune of half a million dollars through a new partnership.

The W113 SL is a glamorous two-seat roadster, which replaced the 190SL. It was introduced as the 230 SL at the 1963 Geneva Motor Show, then was gradually replaced by larger-engine models until the end of the line in 1971. The model was quite popular in the U.S., where nearly 20,000 were sold.

“We were on a route to develop a battery powertrain in-house at Hemmels, and we began to realize what a complex undertaking it is, given international regulations. That’s when we discovered that Everrati had already engineered a solution,” says CEO Tom Butterfield.

The result is a collaboration between Hemmels and Everatti—which restores and electrifies classic “icons” from Porsche, Mercedes, and Land Rover from its base in Bicester, Oxfordshire. Hemmels will restore the cars and Everrati will install electric powertrains. The partnership will be officially announced on Friday, and SLs from both companies will be shown at the upcoming Pebble Beach Concours d’Elegance during Monterey Car Week (Aug. 9-18). The first jointly produced car should be available to customers in November or December. Ordering a car and taking delivery will take eight to 10 months.

The price for a full Hemmels build, with the Everrati electric drivetrain, is £400,000 (US$513,000), excluding the donor vehicle that the company can locate for customers. The cars will be offered internationally.

The SLs will have 68-kilowatt-hour batteries, distributed to help maintain the car’s ideal front-rear balance.

“The bulk of the weight will be where the original engine and gearbox were located, and there will also be batteries in place of the fuel tank and a small pack in the boot [trunk] occupying about the space of the spare tire,” says Justin Lunny, Everrati’s founder and CEO. As battery technology evolves, Lunny says, it should be able to get a more powerful pack into the same locations, and upgrades can occur.

Another British company Helix, a Lotus supplier, will provide a power-dense but compact 300-horsepower motor that together with the battery pack should yield a range of 200 miles and a zero-to-60 miles per hour time of under seven seconds. The cars will use a limited slip differential for good grip, and will be equipped for regenerative braking—recapturing energy and allowing “one pedal” driving. “The end result is a very usable driving experience,” Lunny says.

“Our process in rebuilding the cars is very in-depth, and it’s what makes us stand out,” says Butterfield, whose family bought Hemmels in 2018. “We use brand-new and upgraded parts—we don’t restore what’s there unless we absolutely have to go that route.” The restoration process can take 4,000 worker hours, and bespoke buyers have wide latitude in colors, interior materials, and a choice of options. High-end audio and Bluetooth are available.

The cars will have already been rebuilt by Hemmels by the time they take their 130-mile journey to Everrati, where the drivetrains are—very carefully—installed.

Lunny says that the SLs will not be cut up or altered during the drivetrain installation. “We don’t damage the structure of the vehicle,” he says, “and everything is technically reversible. We retain the value of the original vehicle. The owners can keep the original internal-combustion engine, ensuring that it’s still with the car.” Butterfield adds that one of his clients is turning his engine into the base “for a glass table that will be installed in his man cave.”

Lunny describes the SLs as “art pieces that happen to have wheels. We love them like our babies, and everything we do is to a replicable standard, on par with what an [original equipment] manufacturer would do.”

The W113 SLs may be more than 50 years old, but their styling—and appeal across generations—remains timeless.

“It’s not just a certain age or demographic,” Lunny says. “The new audience is the ultra-high-net-worth individuals who adore beautiful iconic cars, especially the Pagoda, but want a clean-air powertrain, with modern air conditioning, that is enjoyable to drive.”

Butterfield intends to keep production relatively low, producing perhaps 10 to 12 electric Pagodas annually. “To stretch to 25 cars per year would risk the quality of our builds,” he says. Some 60% to 70% of Hemmels’ output has gone to U.S. buyers, and that’s one reason the Monterey appearance—the company’s first—is important to the brand.

Hemmels also works its magic on the earlier 190SL, and electric conversions of those models, through the partnership, are possible in the future, Butterfield says.

Porsche has revealed a one-off 911 GT2 RS that brings the extraordinary silhouette of its 935/78 “Moby Dick” racing car onto the road.

Created by Porsche Sonderwunsch with Manthey, the commission began with a near-new GT2 RS. The owner requested greater performance, a Slantnose profile and a rear wing influenced by the limited 911 GT3 R Rennsport.

The most transformative work occurs at the front. Flatter guards and a newly developed headlight arrangement remove the familiar upright 911 face, producing the low Flatnose profile associated with Porsche’s most extreme late-1970s competition machinery and later 1980s road cars.

Grand Prix White paint provides the base for a contrasting U-shaped bonnet graphic referencing the 935/78. That car earned the “Moby Dick” nickname through its vast white bodywork and elongated aerodynamic form, becoming one of the most recognisable racing Porsches ever produced.

At the rear, a new wing uses S-shaped mounts and is intended to increase downforce. The intervention is more than a styling exercise: Manthey’s participation brings the track-development expertise required when bodywork and aero surfaces are changed on a car with GT2 RS performance.

What makes the project significant is its road legality. Recent Porsche special projects have demonstrated growing demand for factory-sanctioned cars that sit between restoration, motorsport homage and contemporary commissioning. Sonderwunsch allows a collector to pursue an individual idea while keeping the work within the manufacturer’s technical and historical ecosystem.

Porsche has not disclosed the commission price or full performance data. With only one example, conventional availability is irrelevant. Its wider influence lies in showing how far Porsche will take personalisation when a client’s brief, budget and the underlying vehicle align.

For collectors, the resulting car is not a replica of Moby Dick. It is a modern GT2 RS that uses one of Porsche’s most dramatic racing silhouettes to create a new object — and one that can legally leave the collection for the road.
