Every Mitsubishi dealer in the UK will be giving away one Mirage supermini model to customers that enter a competition linked to boosting test drives.
All customers that take a test drive in the Mirage between July 1 and November 30 will be entered into a prize draw to drive the new model for a year.
Mitsubishi has sold 1,300 Mirages since its launch earlier this year.
The Japanese brand is building up sales since volumes have fallen from 15,552 in 2008 down to 6,549 units last year. Mitusbishi has already registered 5,034 units in the first six months of 2013 with volumes up 41.84% in comparison to last year.
