Yamaha Motor's lightweight two-seater car, MOTIV, which was unveiled in last year's Tokyo Motor Show, is rumored to be out for sale in 2015, starting in Europe.
MOTIV was jointly designed with a team including Gordon Murray (Gordon Murray Design) who has worked with McLaren F1. It's built based on the skeleton frame "i-Stream" technology that consists of steel pipes and carbon.
Hokkaido University and RIKEN AICS are researching aerodynamics simulation, to simulate the air flow around automobiles. Investigating the force exerted by air on a moving car is essential for improving fuel efficiency and safety. In particular, using a supercomputer called K has made it possible to simulate air resistance, which is the most important factor, with a precision equivalent to wind tunnel tests.
