Our bespoke electric conversion service offers fully customised, one-of-a-kind EV retrofitting tailored exclusively for classic cars, vintage vehicles and special-interest automobiles. Unlike standard off-the-shelf conversions, every project begins with a complete vehicle structural analysis, chassis evaluation and usage requirement assessment to design a fully personalised electric powertrain, battery layout and driving performance profile. Our engineering team custom-tunes acceleration, torque output, range characteristics and weight distribution to align with the owner’s driving style, aesthetic expectations and intended use, whether for daily road use, show display or long-term collection preservation.
