Nissan's premium brand Infiniti introduced the third generation of the M-Sedan in 2005 based on the Japanese Nissan Fuga.
When Nissan decided to offer a better car, it meant it. The M-Sedan was a mid-size vehicle built with a mix of technology, luxury, and performance. As a result, the M-Sedan outperformed most of its competitors on the market.
By 2005, Infiniti already found its design cues and established a line to keep its vehicles' shape in a common trend. On the M-Sedan, the swept-back headlights resembled those installed on the G35 Coupe and those on the EX-series. Its raked grille with chromed horizontal slats was already known on the market. To emphasize the car's performance sedan orientation, the designers made the rear window sloped and the decklid short.
Inside, the high bolstered seats at the front were inspired by those from the G35 Coupe. Infiniti placed four dials in the instrument cluster, just like most of the other carmakers, but the fuel-level and the coolant-temperature gauges were larger than usual. On top of the center stack, the M-Sedan featured a screen for the infotainment system similar to the one from the Nissan Primera, controlled via a distinct control panel.
Under the hood, Infiniti installed two engine options and an all-wheel-drive system carried-over from the mighty Skyline GTR. All versions were paired to a 5-speed automatic transmission.
