How does it compare?
The RBW Roadster may look like a blast from the past, but it competes in a surprisingly modern field of stylish, niche EVs. Rivals like the Wiesmann Project Thunderball, Mini Cooper SE Convertible, Fiat 500e Cabrio, and MG Cyberster offer variations on the theme—retro, electric, and built to turn heads. So how does the RBW compare on specs and charm?
Range
With 241 km (150 mi), the RBW trails the Wiesmann Thunderball (500 km / 310 mi) and Cyberster (580 km / 360 mi). Fiat 500e and Mini SE hover around 180–230 km. The RBW holds its own for casual cruising but isn't built for extended road trips.
Acceleration
The Roadster’s 8-second 0–100 km/h sprint is sedate compared to MG Cyberster (3.2 sec) and Wiesmann (under 3.0 sec). Mini SE manages 7.3 sec, while the Fiat 500e comes in at around 9 seconds. The RBW prioritizes grace over g-forces.
Power
At 94 hp (70 kW), the RBW is outgunned by nearly all rivals. Thunderball brings over 600 hp, Cyberster packs 536 hp, and Mini SE and Fiat deliver 181 hp and 117 hp respectively. But none look quite like a 1960s Brit classic on wires and chrome.
Charging Time
With no fast charging, the RBW’s 6–8 hour AC charging is the slowest here. Mini SE and Fiat 500e offer 50–85 kW fast charging. Cyberster and Wiesmann promise over 200 kW. But again, the Roadster isn’t for those on a timetable.
Price
At $135,000 (€126,000), the RBW is more expensive than Fiat ($35,000) and Mini SE ($47,000), but cheaper than the Wiesmann Thunderball ($300,000+) and Cyberster (expected $60,000–$80,000). It lands in a niche all its own—high-end nostalgia with a modern twist.
