The M30, M45, and M35 are luxury cars from Nissan's Infiniti marque.

1990

The original 1990 M30 was the mundane middle offering of Nissan's Infiniti brand. It featured a 162 hp 3.0 L V6 shared, along with its front wheel drive platform, with the Nissan Maxima. The vehicle was replaced after 1993 by the more interesting rear wheel drive Infiniti J30. A similar Maxima derivative, the Infiniti I30, was introduced in 1996.

2003

The 2003 M45 is based on the Y34-series Nissan Gloria/Nissan Cedric, with styling similar to the Gloria. The engine is Nissan's 340 hp VQ45DE V8 which produces 333 ft.lbf of torque. The rather Japanese squared-off styling did not make much of a splash on the market, and the M45 sold poorly.

2005

Infiniti released a completely redesigned M45 for the 2006 model year to further compete with its rival automakers' sport-luxury sedans. Based on the Y50-series Nissan Fuga, which uses the FM platform, the M45 is powered by a 4.5 L V8 and produces 335 hp and 340 lb-ft of torque. Additionally, a new 3.5 L V6 version bears the M35 name, and boasts 280 hp and 270 lb-ft of torque. All wheel drive is offered as an option on the M35x.
