If you’re waiting for the familiar thrum of an air-cooled flat-four, forget it. The Knepper 1303 RS-E doesn’t bark, sputter, or cough to life. It erupts. The rear wheels haze over instantly, tire smoke billows behind the stubby fenders, and bits of rubber are left tattooed on the asphalt. Whatever nostalgic image you have of a gentle, smiling VW Beetle, throw it out the window. This thing is a railgun in retro sheetmetal.

And yes—purists, clutch your pearls now—the beating heart of this Franken-Bug isn’t a boxer engine at all, but a modern three-phase asynchronous electric motor. Sacrilege? Maybe. But the team behind it calls the RS-E a perfect marriage of classic charm and cutting-edge EV engineering. After a few minutes behind it, it’s hard to disagree.
FROM JUNKYARD TO ELECTRIC MONSTER
Meet Rüdiger Knepper, the man behind Knepper Bugs & More and the mastermind of this project, along with his son René. The duo found the donor car—a battered 1975 VW 1303—rotting away in a California junkyard. Structurally sound but cosmetically trashed, it was the ideal canvas for a complete reimagining.
The restoration was obsessive. Every bolt removed, every system rethought. The body was returned to factory-fresh crispness and repainted in a rich Marathon Blue. Carbon-fiber rear fenders add subtle width, while a carbon roof spoiler delivers high-speed stability and a hint of motorsport intent. It looks like a Beetle, sure—but not quite like any Beetle Wolfsburg ever imagined.
PORSCHE BONES, TESLA MUSCLE
Underneath the retro shell, nearly nothing remains stock. The suspension is largely Porsche 944, enhanced with KW, Bilstein, and Kerscher hardware. Brakes come from a 944 Turbo S, with Porsche 964 rotors up front. Grip is courtesy of Toyo Proxes TR-1s—195/45R17 up front and 235/45R17 out back—wrapped around Porsche Cup 2 wheels.

Then there’s the battery situation. Seventeen Porsche Taycan modules, split across the chassis, feed a Tesla Model S Performance rear-motor spinning modified voltage. No transmission—just direct drive through Porsche 930 axles delivering absurd levels of torque straight to the pavement.
The result? A fully charged Beetle that hits 100 km/h in 2.8 seconds. Let that sink in. A classic Bug running toe-to-toe with supercars. Top speed: 190 km/h. Range: up to 250 km from a 48-kWh pack if you’re gentle—though gentle driving probably isn’t why you build a 600-hp electric Beetle.
CALM MODE? SORT OF.
With traction control absent, Rüdiger Knepper wisely offers “street mode,” capped at around 200 hp—still a massive bump over anything the original Bug ever dreamed of. TÜV regulators approve that figure for public roads. Switch to full output, though, and the RS-E unleashes all 604 hp and 702 Nm of barely manageable fury. “Race only,” warns Knepper, and he isn’t joking. Even dialed back, acceleration is immediate, linear, and punch-you-in-the-chest violent.

Charging comes via CCS or standard AC with an adapter. The hardware install is pure Knepper craftsmanship; the brain behind the system—the electronic control unit—comes from Alexander Lührmann and his ESDI EV Technologies team in Herford.
INSIDE: ORIGINAL BEETLE, WITH MODERN ATTITUDE
The cabin keeps most of its vintage quirks, minus the parts an EV doesn’t need—no clutch, no gear lever. Instead, you settle into wonderfully supportive Recaro seats borrowed from a BMW 2002. Heating comes from an electric unit tucked beneath the rear bench. It feels familiar, cozy, and deceptively innocent. Until you tap the accelerator.


TRADITION BE DAMNED—THIS IS GENIUS
Some will insist an electrified Beetle is a crime against automotive heritage. But spend a moment in the 1303 RS-E’s presence and you realize this isn’t replacing history—it’s rewriting it with blistering, tire-vaporizing enthusiasm. Knepper’s creation respects the original Beetle’s playful soul while injecting enough power to terrify modern sports cars.
It’s absurd. It’s brilliant. And it proves that sometimes, the best way to honor the past is to electrify it until the tires scream.
