 While the M45 has a shorter length than the Q45, it boasts more interior room, greater performance, a superior rear multilink suspension and front double wishbone, and much friendlier ergonomics, so it succeeded the Q45 as Infiniti's flagship.A new Q flagship was anticipated by the end of the 2000s decade.According to Mark Igo, the general manager of Infiniti North America, "the new Q will make the brand better, but it is questionable whether it will be very profitable".
