Racers, mechanics, tinkerers converting classic cars to EVs

DENVER — When Kevin Erickson fires up his 1972 Plymouth Satellite, a faint hum replaces what is normally the sound of pistons pumping, gas coursing through the carburetor and the low thrum of the exhaust.

Even though it’s nearly silent, the classic American muscle car isn’t broken. It’s electric.

Erickson is among a small but expanding group of tinkerers, racers, engineers and entrepreneurs across the country who are converting vintage cars and trucks into greener, and often much faster, electric vehicles.

Despite derision from some purists about the converted cars resembling golf carts or remote-controlled cars, electric powertrain conversions are becoming more mainstream as battery technology advances and the world turns toward cleaner energy to combat climate change.

“RC cars are fast, so that’s kind of a compliment really,” said Erickson, whose renamed ”Electrollite” accelerates to 0-60 mph (0-97 kph) in three seconds and tops out at about 155 mph (249 kph). It also invites curious stares at public charging stations, which are becoming increasingly common across the country.

At the end of 2019, Erickson, a cargo pilot who lives in suburban Denver, bought the car for $6,500. He then embarked on a year-and-a-half-long project to convert the car into a 636-horsepower electric vehicle (475 kW), using battery packs, a motor and the entire rear subframe from a crashed Tesla Model S.

“This was my way of taking the car that I like — my favorite body — and then taking the modern technology and performance, and mixing them together,” said Erickson, who has put about $60,000 into the project.

Jonathan Klinger, vice president of car culture for Hagerty Insurance, which specializes in collector vehicles, said converting classic cars into EVs is “definitely a trend,” although research on the practice is limited.

In May, the Michigan-based company conducted a web-based survey of about 25,000 self-identified automobile enthusiasts in the United States, Canada and the United Kingdom. About 1% had either partially or fully converted their classic to run on some sort of electrified drivetrain.

The respondents’ top three reasons for converting their vehicles were for faster acceleration and improved performance, for a fun and challenging project, and because of environmental and emissions concerns. About 25% of respondents said they approve of classic vehicles being partially or fully converted to EVs.
