There were two generations of the Infiniti G35 sedan, although the second generation is essentially the current G37 sedan with a smaller V6 engine. The G35 coupe lasted only one generation (meaning, same body style) before being replaced by the fully redesigned G37 coupe.

The most recent G35 sedan was completely redesigned for 2007. Changes included a stiffer body structure, revised chassis tuning for better handling, a more powerful V6 engine and a more voluptuous take on the previous G's styling. It was more or less the same size as the outgoing model, but the biggest improvement could be found inside, both ergonomically and aesthetically. Everything was better put together and materials were higher in quality. The 3.5-liter V6 engine produced 306 horsepower and 268 pound-feet of torque. A five-speed automatic transmission with paddle shifters was standard, but a six-speed manual came with the 6MT trim. We'd seriously recommend against this transmission (especially on 2007 models) as it was incredibly difficult to drive smoothly.
