The vehicle's name is somewhat misleading, as it does not sport a rear mid-engine, rear-wheel-drive layout (which is often abbreviated as RMR, or more commonly, MR); it stands for "Magical Relax".

A hydrogen-powered fuel cell vehicle based on the first-generation MR Wagon was presented in 2005, using technology co-developed with General Motors.

The Nissan Moco version was presented as a concept car on the 35th Tokyo Motor Show in October 2001 and then went on sale on April 10, 2002.

[2] This model also sported a slightly stiffer rear three-link suspension setup[3] in an effort to curb body roll and improve stability at high speed.

The model's second generation was previewed at the 39th Tokyo Motor Show in 2005, where a concept called Mom's Personal Wagon was presented, with many features intended to be useful for a mother driving her children, including food trays, a front bench seat and pillarless suicide doors on the left side (which is the curb side in Japan).

None of those would eventually make it to the actual MR Wagon, which went on sale on January 20 (Moco on February 1) the following year, while on the other hand the model features the new keyless entry and start system.

It has the all new Suzuki R engine, which features variable valve timing and an unusually high compression ratio (11.0:1 for the naturally aspirated version).

[6] In December 2015, Suzuki announced that production of the MR Wagon would end, and that supplies of the car to Nissan had already been halted.
