How a plug-in hybrid electric conversion of a classic VW Bus works, how far it goes, and where things stand. Where we don’t have an answer yet, we say so.
A planned, complete restored VW Bus with a plug-in hybrid electric conversion. An electric motor drives the wheels; a small onboard gasoline generator extends the range. Duet Drive is developing its first Bus. Specifications have not yet been finalized; orders are not open and no Duet Bus has been delivered yet.
The planned launch vehicle is a restored split-window Volkswagen Type 2 Bus. Specifications have not yet been finalized. Images and the configurator illustrate the design direction; donor details, equipment and finishes will be confirmed before orders open.
The restoration plan includes: bodywork, fresh paint and a renewed interior, in colours and upholstery true to the original style. What is new is underneath — electric drive, a battery, and a small gasoline generator. The standard cabin is planned around familiar gauges, knobs and switches. Bespoke cabin ideas are reviewed separately.
No. Duet Drive is an independent company, not affiliated with or endorsed by Volkswagen AG. We restore and convert classic Volkswagen Buses; Volkswagen and VW are trademarks of Volkswagen AG.
The ID. Buzz is a new, battery-only electric van from Volkswagen; for the 2025 US rear-wheel-drive model, Volkswagen quotes 234 miles of EPA-estimated range. A Duet Bus is a restored classic Bus with a plug-in hybrid conversion: you plug in for everyday electric driving, and a small gasoline generator lets you refuel at any pump for long trips.
The engine never drives the wheels. It turns a generator. Everything that moves the Bus is electric, so it pulls like an electric car. Plug in at home for local trips; on longer journeys the generator makes electricity from gasoline, and you refuel at any gas station.
Our calculated total range is 375–430 miles at 55 mph, or 310–350 miles at 65 mph. On battery alone it is approximately 65–85 miles at 65 mph. These are engineering estimates, not tested or EPA-rated figures, and all fuel-based estimates use a 10.6-gallon usable tank.
Plug it in: a full charge takes approximately 5–7 hours with the planned 6.6 kW onboard charger and a suitable 240 V supply. The charging hardware is still under evaluation, and the plug type is not yet final. The generator runs on ordinary gasoline, which refuels the generator, not the battery.
Like an electric car in a classic Bus: smooth, quiet power from the electric motor. The simulator uses development targets of 0–60 mph in about 7.6 seconds with the standard battery configuration and 5.6 seconds with the upgrade. These are simulated targets, not measurements from a finished vehicle. Specifications have not yet been finalized.
The target starting price is for a complete restored VW Bus with the standard Duet drive system. Design shows that target plus selected guide-price options. Tax, title, delivery, bespoke finishes, battery upgrades and unpriced options are additional. Final equipment, inclusions and prices will be confirmed before orders open.
Paint: one of six house colours — Pastel White, Black, Titian Red, Neptune Blue, Velvet Green or Kansas Beige — or a bespoke colour match. Upholstery: basketweave vinyl, houndstooth cloth or bespoke leather. The 3D preview offers stock hubcaps or EMPI 5-spoke wheels. Explore guide-price accessories and bespoke ideas in Design and Bespoke. All selections remain subject to feasibility, availability and final pricing.
Orders are not open yet, and we have not announced a delivery date. Join the waitlist to be told first when build slots open, and to follow development of the first Bus.
There is no deposit. Joining the waitlist takes no payment and does not reserve a Bus or a build slot. We write at most once a month — build news, photos, offers and word of when build slots open — never share your address, and every email has a one-click unsubscribe.
Not decided yet. Our launch plan is for complete restored VW Buses. If we offer conversions of customer-owned Buses, we will say so here before orders open.
Not currently. The launch vehicle is the VW Bus. Bespoke camper and lounge images are concepts for consultation; their equipment and capabilities are not finalized.
We are evaluating seat layouts, entry and exit, air conditioning, cabin insulation and luggage space for the VW Bus. Seat count, seat belts and child-seat provision, brake specification, heating and cooling performance, and cabin noise are not finalized. We will publish the confirmed equipment and test results before orders open.
The service and parts-support plan is still being developed. We will explain who can maintain the restoration and the hybrid system, what support is available, and the warranty terms before orders open.
We have not announced where Duet Buses will be restored and assembled. We will publish it before orders open.
Warranty terms are not final. We will publish them before orders open, and before anyone is asked for a deposit.
Registration and emissions requirements for converted classic vehicles vary by state, and our compliance work is not complete. We will publish how registration works for a Duet Bus before orders open.
