First Unveiled at the 1985 Frankfurt Autoshow, the MID4 was a concept car designed by Nissan to originally go on sale in the mid-late 1980s. Nissan had aimed the MID4 to compete with European supercars from Porsche and Ferrari. It featured a mid-engined all wheel drive layout as well as a wide array of technology and features that would eventually find their way into other Nissan production cars. The MID4 prototypes would evolve into the MID4 II, though it would never be put into production.
The responsibility of creating the MID4 was given to a team of designers headed by Shinichiro Sakurai in the Spring of 1984. The progress of Sakurai's MID4 team was amazingly rapid, the first four prototypes were completed by March 1985.
The MID4 was first unveiled at the 1985 Frankfurt Autoshow. The AWD system distributed the power from the naturally aspirated VG30DE 33% front 67% rear, and was the predecessor to the ATESSA system. The MID4 was also the first car to feature Nissan's brand new 4 wheel HICAS steering system and had a claimed top speed of 155 mph.
The MID4 II made its debut at the 1987 Tokyo Motor Show and featured many revisions to the previous design. The MID4 II sported the twin turbo intercooled VG30DETT which put out 330 hp. The MID4 II was ultimately never produced due to cost.
