High Quality Content by WIKIPEDIA articles! The Mitsubishi MR platform is an automobile platform first developed by Mitsubishi Motors in 2003 for their Mitsubishi i kei car. The name is derived from the Mid-engined, Rear-wheel drive ("MR") configuration, which locates the powertrain behind the rear seat and just ahead of the rear axle. This allows for a longer wheelbase and a consequently more spacious interior without compromising crash- worthiness or fuel economy. The company has also used the platform in several of its concept cars, particularly those using alternative propulsion. The i-Concept and Se-Ro were the first publicly exhibited vehicles to use the MR platform, as they previewed the production version of the i at motor shows in advance of the car's release. Since then, the Concept-CT, i-MiEV, and i MiEV Sport battery electric concept cars all exploited the MR platform.
