Renault Alpine, C37 BRM, C46 Porsche 917K, C47 Tyrrell Ford, C50 JPS Lotus 72 Micro Scalextric Micro Scalextric (or MicroScalextric, as appears on product boxes) was launched on 1 February 1994 (then known as Scalextric Micro MR-1) at the Olympia toy fair. It became available to the public in October of that year and used a much smaller track geometry to the standard Scalextric product. Many of the Micro MR-1 models were re-badged products manufactured by Marchon, Inc. In 1995, again at the Olympia toy fair, a new track system was introduced along with new vehicles. At the same time Scalextric Micro MR-1 was re-branded as Micro Scalextric. The Micro Scalextric range is aimed at children four years of age or older and has a scale of 1:64 and is often, incorrectly, described as HO scale (1:87). There is also a 'My first Scalextric' range, aimed at 3-year olds. In February 2019 a new track system was introduced. Warner Bros have licensed a number of Looney Tunes characters for use in the Micro Scalextric range of products. The latest (2019) range Micro Scalextric slot car motors run on 9v, which is different to earlier Micro Scalextric vehicles.
