The Infiniti G is a car brand line that is listed in the executive and entry-level class due to its looks. It was manufactured by the Infiniti division of Nissan starting from 1990 to 1996. Nissan then restarted the production of the car model in 1998 and it has not stopped since. From its third generation, the Infiniti G has been versions of the Nissan skyline sedans and coupes that were being exported to Canada and the United States. The hardtop coupe convertible was introduced in this car brand’s fourth generation. The third and fourth generations of the Infiniti G have been built on top of the Nissan 370z and they share components with the Infiniti FX, the Infiniti Ex and the Infiniti M.
The first generation, also known as the P10
The Infiniti G20 was the first car in this brand line. It was introduced in the 1990’s and it resembled the Nissan Primera in that they both had higher levers of standard interiors and equipment. All the cars in the G20 series were front-wheel driven and were built in Japan.
The G20 had a SR20DE Inline 4 cylinder engine that had a displacement of 2.0 liters. The engine used on the G20 could produce up to 140 hp. The later models that were shipped to the United States post-2000 could produce up to 145 hp. Due to the fact that these engines had very high fuel economy, they were flexible, very reliable and had very high power-handling capabilities; hence, they became very popular in the import scene as well as the tune sub-culture.
This first generation of the Infiniti G came with either an optional 4-speed automatic transmission or the standard 5-speed manual transmission system. Since the systems in this car generation were easy to modify, front wheel transmissions could be easily installed into these cars.
The second generation, also known as the P11
The second generation of the Infiniti G underwent a few changes before it was released into the public domain. One of these changes was the inclusion of a multi-beam rear suspension that was thought to reduce lateral suspension movement, and thus helped improve handling. This second generations was also a few inches longer and taller and with the additions of a few luxury features, this car weighed more than the generation that came before it.
The aesthetic and luxury changes that were made to this generation included automatic climate control, 15 inch alloy rims, keyless entry, side-impact airbags and a standard power moonroof. The touring models of this Infiniti G generation featured upgraded sports seats, a limited-slip differential as well as 12-spoke alloy rims. The engines in use for his generation were the 2.0L SR20DE that was capable of 140 hp (104 kW) (this was a 1999 model) and the 2.0L SR20DE capable of 145 hp (108 kW) (this was produced from 2000 to 2002).
The G20 got discontinued in 2003 when Nissan decided to continue on with the rear-wheel driven G35 model. This model was slightly larger and more powerful than the G20.
This generation of the Infiniti G was produced between the years of 2002 and 2007. This generation came as either a 2-door coupe or a 4-door sedan. The 6-speed automatic transmission was included starting in 2003 on the sedan as the coupe always had this transmission option. The V6 so available was capable of 194 kW (260 hp) on the sedan and 209 kW (280 hp) on the coupe. In the 2005 and 2006 models, the cars with automatic transmission could produce up to 209 kW (280 hp) and those with manual transmissions could produce 222 kW (298 hp).
The fourth generation of the Infiniti G mainly saw cosmetics changes to the car with not much work done to the engine or the transmission.
