The 600-Horsepower Electric Volkswagen Beetle That Challenges Modern Supercars

An iconic classic reinvented with cutting-edge electric technology: this is the Knepper 1303 RS-E, a Beetle capable of accelerating like a Formula 1 car from another era.

At first glance, this Marathon Blue Volkswagen Beetle 1303 could easily be mistaken for a well-preserved classic. But the moment it moves off, it becomes clear that this is something extraordinary. This Beetle delivers 601 horsepower and 518 lb-ft of torque thanks to a high-performance electric powertrain, making it one of the most radical restomods ever built on the legendary German icon. The project proves that electrification can not only respect, but significantly enhance, the legacy of the automotive greats.

From air-cooled classic to electric missile

The heart of this transformation is not an air-cooled boxer engine, but a modern three-phase asynchronous electric motor. For purists, that may sound like heresy, but for Rüdiger Knepper, founder of Knepper Bugs & More, it represents the natural evolution of the concept. In normal use, the car is limited to 200 hp to comply with TÃV regulations, while its full output is reserved for track use. Even so, the power delivery is brutal–instant and relentless–hurling the Beetle forward with an intensity worthy of a modern single-seater.

The project began with a 1975 VW 1303 rescued from a California junkyard. While the bodywork was badly damaged, the structure was sound–ideal for a full ground-up rebuild. During the restoration, almost every component was replaced or upgraded: the body was returned to near-original form but gained wider carbon-fiber rear fenders and a carbon roof spoiler, improving high-speed stability without compromising the classic silhouette.

From a technical standpoint, the chassis is a genuine engineering showcase. Much of the suspension comes from a Porsche 944, combined with components from KW, Bilstein, and Kerscher. Braking duties are handled by Porsche 944 Turbo S calipers with Porsche 964 front discs, while Porsche Cup 2 wheels are wrapped in Toyo Proxes TR-1 tires. Power is supplied by 17 battery modules from a Porsche Taycan, feeding a rear motor sourced from a Tesla Model S Performance. Power is sent directly to the wheels via Porsche 930 drive shafts, eliminating the need for a traditional gearbox.

The performance figures speak for themselves: 0 to 100 km/h in just 2.9 seconds, with a driving range between 100 and 250 kilometers depending on driving style. Charging is possible via CCS fast charging or standard AC using an adapter. Inside, the cabin largely retains its classic character, but a digital control panel replaces the clutch pedal and gear lever. As the ultimate proof of reliability, Knepper drove nearly 8,000 kilometers across Europe–including Spain–and even took a ferry to Morocco, without a single technical issue. An electric Beetle that impresses not only on paper, but in real-world use as well.
