At the Geneva motor show, Mitsubishi announced the global debut of a new concept for a sub-compact sedan named the G4 at the upcoming 34th Bangkok International Motor Show on March 25 thru April 7.

The Japanese carmaker isn't ready to divulge too much information on the G4 study yet, but from what we know, it'll be based on the new five-door Mirage hatchback that's already on sale in a number of countries around the world.

From this single teaser sketch released by the company, it appears the G4 will bear some styling similarities with the CA-MiEV concept. According to Mitsubishi, the G4 is powered by a lightweight and compact 1.2-liter MIVEC engine mated to a CVT, which is probably the same 79HP drivetrain found in the Mirage.
