Spanish car maker SEAT has upgraded its Mii model with a new automated manual gearbox.
The company claims that the Mii Auto is 2.7mpg more fuel efficient on average compared to the Mii Sport, which has the same 1.0-litre 75PS engine with a manual gearbox.
SEAT's new automated version features an average fuel consumption of 62.8mpg and a 105g/km CO2 rating, compared to the Mii Sport's 60.1mpg and 108g/km.
The new model is based on the manual five speed gearbox, replacing the manually operated clutch with an electric motor linked to a pair of electromechanical actuators to handle gear changes.
It weighs around 30kg, three kilograms more than the Mii's five-speed manual.
The Mii Sport's 13.2 second 0-62mph time increased slightly to 13.9 seconds in the Mii Auto, while the top speed remains at 106mph.
SEAT's new automated gearbox offers three settings for drivers including neutral (N), drive (D) and reverse (R).
The Mii Auto comes in both three- and five-door body styles and orders will start in November 2012.
