He founded Tokyo R and D in 1981 and his Maki colleague Kenji Mimura also worked there for a while. In more recent years, Masao's company have focused on electric cars and in particular, the battery management system of these vehicles, although in truth, Ono has been involved in that part of the automobile world for some thirty years and is one of the leading experts in the electric car engineering industry. Masao also has business interests in England through his Vemac car firm. Ono's firm had designed a road sports car called the Cadwell but in the mid 1980's, he formed up with Chris Craft, the former Grand Prix driver and his son, to design the Vemac RD180, which is effectively a racing car converted into a sports road car.
