Many areas, and large cities in particular, are ready to transition to all-electric mobility in just the next few years. As such, it's important to find a find a way to integrate classic cars without ruining their character. The Aston Martin Cassette Electric Powertrain Concept is an attempt to do exactly that. Shown for the first time in a 1970 DB6 MkII Volante, the "cassette" as an all-in-one system that sits on the original engine and gearbox mountings, connecting to the car's electrical systems via cords. Power management is handled via a screen discreetly integrated into the car's interior, and most importantly, the process is completely reversible, giving the owner the option to reinstall the original powertrain in the future.
