Volts Wagens: Old Bugs go from Gross Polluters to EV Stars
Brian Steel spent 34 years fixing and tuning Volkswagens at his Small Car Performance shop in Tacoma, Washington, and then had an epiphany watching the movie Who Killed the Electric Car? Cars were going to plug in, and he wanted to become part of the solution. Henceforth, he would sell battery-powered Beetles!
The humble Volkswagen Beetle was the green star of its day—a 25-mpg mini-micro– sharing space with the be-finned and lavishly chromed highway cruisers of the 1950s. Award-winning ads made a virtue of its modesty. But, by today’s standards, the Greenpeace-friendly Beetle is a gross polluter.
Auto engineer John DeCicco, once the proud owner of a ’71 Karmann Ghia (“the poor man’s Porsche”) and now a senior lecturer at the University of Michigan, says flatly, “In terms of smog, a brand-new large SUV emits 100 times less than the old VW Beetles of a generation ago.” Jim Kliesch, a senior analyst in the clean vehicles program at the Union of Concerned Scientists, did some back-of-envelope calculations and concluded that compared to an average new car today, a mid-60s Beetle produced 141 times more hydrocarbons and 80 times more nitrogen oxides (the two together produce smog).
“You kill a lot of emissions by converting a mid-60s Beetle to an EV,” Kliesch said. ”Then again, compared to that car, you’d cut a lot by replacing it with anything in the showroom today.”
No fancy emissions controls for the classic Beetle. “It was a carbureted vehicle with no catalytic converter,” Steel said. “They were no worse than other cars of that age, and probably better than the gas hogs, but unfortunately they were often driven out of tune and would run pretty well that way. So there was no incentive to get repairs.”
Back in the day, hippies used peace symbols for structural repairs, and dog-eared copies of John Muir’s How to Keep Your Volkswagen Alive: A Manual of Step-by-Step Procedures for the Complete Idiot for infrequent maintenance. Hey, it got you to the Dead concert. My friend drove his Bug until the six-volt battery fell through the floor and dragged on the highway by its positive and negative cables.
I never owned a Beetle, but I had a ’68 Squareback with the same engine, and vividly remember the clouds of blue smoke rising from the rotten floorboards. Even in the dead of winter, I drove with all the windows open. You know how people call Car Talk and complain about the “funny noise”? These things produced symphonies of rattles and groans, and their smoke trail hung in the air long after they had “trucked” down the road.
For Steel, those exhaust clouds formed into a message spelling out a new destiny. He began with an intermediate step—replacing the sluggish 15-mpg power plant in the VW ’83-’91 Vanagon with a modern Subaru replacement, jacking the car up to 24 mpg on the highway. “I really got into it,” said Steel, “a custom aluminum bell housing, stainless exhaust pipes, the works.”
Soon he’d done 135 Vanagon conversions (there must be some kind of cult for these cars on the West Coast) and the road was paved for the electric Beetle and New Leaf EVs. Steel has converted exactly one car, but he’s already offering his services to the public on the web and has two other donors waiting for heart transplants.
The prototype is a very clean two-owner 1963 Beetle procured from an elderly woman owner in eastern Washington. Neatly slotted in the engine compartment and taking over from the gas tank are a bank of AGM lead-acid batteries, which couple to a brush-less AC induction electric motor. A regenerative braking system captures energy that would otherwise be lost as waste heat.
The Beetle weighs 1,600 pounds and the batteries add another 300, so it’s still a very light platform for an electric car. The second car will get an upgrade to vastly more efficient lithium-ion batteries—for 100 miles of range instead of 40 in the prototype. The basic conversion is $9,975 plus the donor car, but batteries are extra (lead-acid packs are $1,975; lithium-ion adds $8,575). I haven’t driven the electric Beetle, but a reporter for Ruralite Magazine did.
“Put the key in the ignition and turn it on. There’s nothing but a faint ticking sound. Press the accelerator. Silent forward motion, seems eerie at first. Steer into traffic and keep pace. Stop at a light. There’s that eerie silence again. No VW roar. No gassy smell.”
Steel is enough of a classic car guy that he insists on installing the electric hardware into his electric Beetles without drilling any new holes or cutting panels—they could be converted back to gas, should history reverse itself. A hybrid conversion is next.
New Leaf EVs are not alone. Rebirth Autos makes a conversion kit that in one $9,000 version includes AGM batteries and a NetGain Warp 9 motor. But buy some overalls, because you install it yourself.
Richard from Olympia, Washington, created the “Volts Wagon”—a ’75 convertible and plans to charge the batteries with rooftop solar. Here’s the video evidence:
The Wired Autopia blog has also been chronicling the transformation of Matthew Redd’s typically rusty Bug into an electric paragon. “Wow, it runs!” he wrote in March. Mark Clifford is doing a Porsche 911 Targa. There’s something about these funky (remember “funky”?) little cars that begs for a green rebirth. Far out, man, my Beetle plugs in.

Sounds like a great idea for these wonderful little cars. It just needs a digital soundboard like they put in model trains to emulate the engine sound of a classic VW, I know I would miss the sound.
$9,000 to convert a Beetle to electric, plus another $9,000 for the batteries!? $18,000 buys a lot of gasoline. $18,000 will buy a used Mustang GT convertible I could actually have some fun in, and get highway mileage that rivals a 1960’s Beetle.
Besides, what’s going to happen when millions of EV’s plug into the grid at 6:00 at night? And have they solved the problem of range in frigid climates like the northern Midwest and New England?
There are places and situations where EV’s and solar energy are the answer, and those where they are not. For now, anyway.
We keep hearing about how new vehicles, especially hybrid and/or electric vehicles are so much cleaner than old cars. Until the manufacturing & supply process changes and battery technology improves…its safe to say that you could drive that old car for a few more miles before the production & shipping of that ‘clean’ hybrid offsets the old, “polluting” car.
Did I missed something? It cost about $20 on parts and labor plus another $20 to $40 on electric roof panels so one can drive a 40 year old unsafe, unreliable car! Not to mention the tremendous amount of solid(toxic)waste generated in used lead batteries after all these ones start going dead.
Why not just save the money and buy a new Technology from a reputable manufacturer ( Nissan or Toyota come to mind) and save the headaches. I rather have a new car crash tested, reliable, with A/C- and heater, ABS-Brakes, etc, etc.
While we are trying to make 40-year old cars run on electricity other countries ( Japan, China) are leaping over our heads on technological innovation.
As a vanagon and vintage beetle owner, very interesting.
ecos also does this conversion http://www.ecosmotors.com/main.html
I have been impressed with the quality of small car performances products I have purchased for my vanagon and would expect the same from their ev kit. I do take exception to the mileage figures for vanagons, however. Only the most out of tune vanagon with stock motor gets 15- mine- with a high top and being 4 wheel drive still manages 18 without much problem. the subaru conversion, while offering more power and with new electronics, undoubtably cleaner, seldom helps much in way of mileage- not like the 9mpg the article claims- and the 6 cylinder subies usually get worse mileage.
Great to see more companies combining vintage cars and green thinking. I have been itching to convert my 68 bug convertible, but am waiting for the lithium battery price to come down.
$18,000 for 100 mile range? You’re nuts!!! The technology is definitely not there yet.
I remember dem days fondly. Had a VW bug painted dayglow pink (ran out of spray paint, so it looked like pink spaghetti). Drove it to every hippie rock concert on the East coast, and even drove it through Wash.D.C. during the MLK riots. Sounded like a hundred tin wheels rubbing against each other. Order me two electric models – will you take an IOU?
I think all average commuters should have plug-in electrics, as most of us only make short trips. If an extended distance is required, just rent a hybrid (even long-haul big rigs would benefit from being retrofitted as miniature diesel-electric locomotives).
“far-out” glad that it’s no longer far off !!!
