Seat introduces an automated manual gearbox to the Mii range image

SEAT has announced the introduction of an automatic gearbox on its smallest model, the Mii city car.

The automated manual gearbox combines the confort of an automatic transmission with the improved fuel consumption of a manual.

The new transmission will be available with the 1.0-liter 75 hp engine and Seat claims its “extremely economical”. According to the official specs, the Mii Auto is 2.7 mpg more fuel efficient on average than the manual version (Mii Sport). Also, CO2 emissions are lower too.

The average fuel consumption of the Mii Auto is 62.8 mpg, with CO2 emissions rated at 105 g/km (60.1 mpg and 108 g/km on the manual). Based on the manual gearbox, the automated version utilises an electric motor linked to a pair of electromechanical actuators to handle gear changes.

The gearbox is only available with the 75 hp engine and in SE trim, and currently Seat has no plans to offer it with the lower powered 60PS engine. The downside of choosing the Mii Auto is the car’s slightly slower acceleration, as the 0-62 mph sprint is done in 13.9 seconds, half a second slower than the Mii Sport. Top speed remains at 106mph.

The Mii Auto is available in both three- and five-door body styles and is priced at £10,390 and £10,740 respectively. The first cars will be delivered in early November.
