Born in 1990, the Infiniti M Sedan has grown to be the largest sedan in the current Infiniti Lineup. Since its humble beginnings as a respectable mid-sized sedan, the Infiniti M has blossomed into the quintessential executive luxury saloon. With a sculpted design, supple interior, and no shortage of get-up-and-go, the Infiniti M satisfies the most discerning driver. Variations on the theme include the Infiniti M37 at 330 hp, the Infiniti M35h Hybrid at 360 hp (and 32 mpg highway), and the forceful M56 at 420 hp.
