The five-door Mazda2 with a four-speed Automatic gearbox will be named TS2 Automatic when it arrives within the next month.
The transmission helps the small car achieve CO2 emissions as low as 146g/km on the combined cycle and 44.8mpg from the 1.5-litre engine.
Slightly more expensive than standard manual models, the Mazda2 Automatic costs £12,370 on-the-road.
Mark Cameron, Sales Director at Mazda UK said: "The Mazda2 Automatic has been launched due to significant public demand. We expect it to become one of the best selling Mazda2 derivatives, helped by demand from Motability drivers and sales generated by our driving schools programme."
Expanding the three- and five-door Mazda range to nine, the automatic model is expected to be a best seller because of the demand for automatic models from driving schools and Motability, where cars can be modified to suit a driver’s needs.
Standard models will feature air conditioning, electric windows and door mirrors, CD radio and remote central locking.
TS2 models add 15" alloy wheels, leather steering wheels with audio controls, split rear seats and Dynamic Stability Control.
The Mazda2 Automatic will be available from 4 January 2011 and all prices are inclusive of the new 20 per cent rate of VAT.
Manual models in the range will cost from £10,305 under the new VAT, and come with a range of engines from the 1.3-litre petrol engine to a 1.6-litre 95PS diesel unit. Four trim levels are also available; TS, TS2, Tamura and Sport.
