When Nissan set out to elevate its mid-size luxury sedan game, the result was the 2005 Infiniti M-Sedan - based on the Japanese Nissan Fuga. This new generation marked a serious commitment to blending advanced technology, refined luxury, and sports-sedan performance, positioning the M-Sedan ahead of many rivals in its segment.
Infiniti had by then established a cohesive design language across its lineup, and the M-Sedan proudly followed suit. Its swept-back headlights mirrored those seen on the G35 Coupe and EX-series, while the raked chrome grille with horizontal slats gave it a confident, premium look. A steeply sloped rear window and a short decklid enhanced the car’s dynamic silhouette, reinforcing its performance-oriented DNA.
Inside, the M-Sedan delivered a sporty yet upscale driving environment. Deeply bolstered front seats, inspired by the G35 Coupe, held occupants firmly in place. Infiniti used a clean four-dial instrument layout, though the fuel and temperature gauges were noticeably larger than most competitors'. At the center stack, a multimedia screen - controlled by a dedicated panel - drew from Nissan’s Primera system, combining familiarity with upgraded sophistication.
Beneath the surface, the M-Sedan offered two robust engine choices and an all-wheel-drive system derived from the legendary Skyline GT-R. All models featured a 5-speed automatic transmission that prioritized smooth shifts and reliable performance.
