SEAT Mii

The Mii is Spanish carmaker SEAT's take on the new VW Up! Optimised for urban environments, the Mii uses a 1.0 litre tree-cylinder petrol engine, available with either 59 or 74 hp output. 0 to 62 mph will take around 13 seconds with a top speed of at least 60 mph.

The 74 hp version will return 60.1 mpg combined, whilst emitting 107 gCO2/km - not quite low enough to qualify for London Congestion Charge and VED road tax exemption, however forthcoming 'Ecomotive' models with start-stop technology will reduce both engine CO2 output to 97 g/km. The 3 door version will be available first, with a 5 door option to be introduced later in 2012.
