At first glance, this Marathon Blue Volkswagen Beetle 1303 could pass for a nicely restored classic. Parked, it’s charming. Nostalgic. Almost innocent. But the moment it moves, that illusion disappears completely. There’s no engine noise, no rising revs—just instant wheelspin, thick clouds of tire smoke, and rubber being flung across the asphalt. This Beetle is anything but ordinary.
Meet the Knepper 1303 RS-E—a classic icon reimagined with a shockingly modern heart. Instead of the familiar air-cooled boxer engine, this car runs on a powerful three-phase asynchronous electric motor. To purists, that might sound like sacrilege. To its creators, it’s the ultimate way to give a timeless car a second life without dulling its personality.
The project comes from Rüdiger Knepper, founder of Knepper Bugs & More. “On the road, we usually keep it in standard mode at around 200 horsepower,” he explains. That’s not because the car can’t handle more—it’s because it has a lot more to give. In full attack mode, the RS-E produces an outrageous 601 horsepower and 518 lb-ft of torque. Without traction control, that kind of power is reserved strictly for the track. TÜV regulations cap road use at 200 hp, but even then, acceleration is brutal—smooth, silent, and relentless, like being launched from a catapult.
The story began with a 1975 VW 1303 discovered in a California junkyard by Rüdiger and his son René. The body was rough, clearly neglected, but the structure underneath was solid. That made it the perfect blank canvas. From there, the build became a ground-up transformation, with almost every part either replaced, restored, or completely reengineered.
Visually, the Beetle stays true to its roots. The body was carefully returned to near-original shape and finished in Marathon Blue, with tasteful upgrades that reward a closer look. Carbon-fiber rear fenders widen the stance, while a carbon roof spoiler adds both visual edge and real stability at speed.
Underneath, however, the car is pure performance engineering. Much of the suspension comes from a Porsche 944, paired with high-quality components from KW, Bilstein, and Kerscher. Braking is handled by 944 Turbo S hardware, with Porsche 964 discs up front. The car rides on Porsche Cup 2 wheels, wrapped in Toyo Proxes TR-1 tires—195/45R17 up front and 235/45R17 at the rear—for serious grip.
The electric hardware is just as impressive. Power comes from 17 battery modules borrowed from a Porsche Taycan, feeding a rear-mounted motor sourced from a Tesla Model S Performance, modified to match the system’s voltage requirements. Power goes straight to the rear wheels through Porsche 930 driveshafts, with no traditional gearbox in between.
In perfect conditions, the RS-E rockets from 0 to 62 mph in just 2.9 seconds. Driving range varies depending on how heavy your right foot is, stretching from 62 to 155 miles (100–250 km). Charging is flexible too, with CCS fast charging or standard AC charging via an adapter.
Rüdiger handled the mechanical installation himself, while the complex electronic control systems were developed by Alexander Lührmann and his team at ESDI EV Technologies in Herford.
Inside, the Beetle stays refreshingly familiar. The original layout remains, but the clutch pedal and gear lever are gone, replaced by a clean digital control interface for the electric drivetrain. Recaro seats from a BMW 2002 provide comfort and support, and an electric heater under the rear bench keeps the cabin warm.
And this isn’t just a show car. In May, Rüdiger proved its real-world usability with a four-week road trip across Belgium, France, Spain, Portugal, and Luxembourg—finishing with a ferry ride from Seville to Tangier, Morocco. By the end of the journey, the electric Beetle had covered nearly 5,000 miles (8,000 kilometers) without a single technical issue.
It’s silent, brutally fast, and unmistakably a Beetle—proof that electrification, when done with passion, doesn’t erase character. It simply gives it a new way to shock people.
