Retropower started working on a new vehicle called “Project Q600“. This time the company will be building an Audi Quattro as only they can. Rest assured the car will be powering by an inline-five. Retropower plans on using a more modern 2.5 L 07K inline-five producing at least 500 horsepower. The motor will be backed by a VW 01E six-speed manual transmission and rebuilt Quattro differentials with uprated ratios. Retropower will also be redesigning the exterior with custom carbon fiber body panels. This will be great project to follow and you can do that on their channel.
