Remember the Rocketman concept Mini unveiled back in 2011? It was a dolled-up three-door hatch that was about a foot shorter than the regular Mini Cooper, and had a panoramic glass roof and a carbon-fiber spaceframe. Its main highlight, besides the fancier looks, was its 78 mpg U.S. estimated fuel economy rating. Initially expected to spawn a production car, the Rocketman remained a concept only. That’s about to change according to Auto Express, which found out more about the company’s new plans straight from Mini head of design Anders Warming.
