The Infiniti G-series is a line of car models that was produced by the Nissan Motor Company since the year 1990. This series spans five generations of superior cars developed by the Japanese automobile manufacturer – the first generation in 1990 until 1996, the second generation in 1998 until 2002, the third generation in 2001 until 2007, the fourth generation in 2006 until 2013, and the latest and fifth generation produced since 2013.
Under the fourth generation G-series or the V36 is the Infiniti G37. At the New York International Auto Show in 2007, the G coupé was released, and it came out in the market as part of the 2008 models. In the European market, the G37 was displayed at the Geneva Motor Show in 2009 as a sedan. This was a replacement for the G35 sedan and it adopted the new seven speed automatic transmission of the luxury division Infiniti.
Aside from this seven speed transmission, the G37 can also be acquired with a six speed manual transmission through the so called Sport 6MT model. Other than the coupé and the sedan, a convertible version of the car was also available, and this was released in June 2009. The design of this convertible was based on the coupé versions of the G-series, and in 2011, the Infiniti Performance Line, a new performance division, released the IPL G37 coupé.
