The '''GM M platform''' was the designation used by [[General Motors Corporation|General Motors]] for the platform that underpinned the first, second and third generation [[Suzuki Cultus]] and its offspring.

The first generation of this platform had been designed by [[Suzuki]] for their 1983 Cultus, and adopted by [[Chevrolet]] with the introduction of the Sprint.

The platforms of the second and third generations first appeared in 1989 and 1995 respectively.  They were designed at GM's Technical Center in Warren, [[Michigan]], USA.  [[Suzuki]] designed all the engines, drivetrains and actual body. From 1985 through 1989, all models were imported from Suzuki's facilities in [[Hamamatsu]], [[Japan]]. From 1990 on, some [[North America]]n M-cars were produced at [[CAMI Automotive]] in [[Ingersoll, Ontario|Ingersoll]], [[Ontario]], Canada with the exception of the [[Convertible (car)|convertible]] and turbocharged models which were imported from [[Japan]].  The third generation '''M platform''' was only sold by [[Suzuki]] as the [[Suzuki Swift]] in [[North America]] as [[Suzuki]] decided to create their own [[Suzuki Ignis|Swift]] to market around the world.

The following vehicles used this platform:<br />
