The Honda HSC (Honda Sports Concept) is a conceptsports car that was initially unveiled at the 2003 Tokyo Motor Show. Most of the automotive media immediately speculated that it was designed to be a replacement for the Honda NSX, although this was never confirmed by Honda. It was also branded as an Acura.
The HSC featured a lightweight, mid-mounted aluminum 3.5 L (210 cu in) i-VTECV6 engine with a 6-speed transmission controlled by either an F1-style paddle shifter on the steering wheel or a unique dial shifter on the center console. When shifted into reverse, the navigation system's adjustable flat-panel screen in the center console becomes a display for a rear-mounted camera. Abundant leather and aluminum trim pieces round out the interior, an all-aluminum frame with carbon fiber body panels keep it light, and swan doors affirm its sports car status.
The development of this car into a production sports car appeared to stall for two years. However, the July 2005 announcement by Honda CEO Takeo Fukui indicated the HSC was only a test concept for a pure sports car.
