The Infiniti M45

The 2003 Infiniti M45 was designed at the Nissan Technical Center (NTC) in Atsugi, Japan; was manufactured in Tochigi, Japan; and is based on the Y34-series Nissan Gloria. In contrast to the Japanese models, which were available only with V6 engines, the M45 was powered by Nissan's VK45DE V8, producing 340 hp (254 kW) and 333 lb/ft (451 N/m) of torque, which it shared with the Infiniti's flagship Q45.

In addition to the difference in powertrain with the Y34 Cedric/Gloria, the Y34 M45 has a completely different instrument panel design, similar to the F50 Q45. Other differences includes a completely different rear multi-link suspension design. The Y34 Cedric/Gloria's rear multi-link suspension design is similar to Z32 300ZX, and S14/S15 Silvia/200SX/240SX where the rear spring is mounted on the strut. The rear suspension design on the Y34 M45 is very much like the rear suspension design on the Z33 350Z, where the spring is mounted independent of the shock/strut, and sits directly on the lower arm, in a spring cup.

The front suspension design carries over from the Y33 Q45, with an one-piece strut/upright. In place of the stamped steel front lower arm, the Y34 M45 has a cast aluminum lower A-arm.

The M45 allowed Infiniti to expand the use of the 4.5L V8 that had been exclusive to the Q45, thus creating a better economy of scale to cope with that engine's development costs.
