The latest Proton car, codenamed P3-21A is expected for a Feb / March 2012 launch. There has been rumors that the new Proton P3-21A is to be fitted with YES 4G - think of it as "WiFi in Car" feature, which is quite cool IMO ! The price of the new P3-21A is not out yet till the launch.
Wanna see more of the P3-21A's interior and exterior ? Head over to http://www.facebook.com/media/set/?set=a.322260474476472.66484.231326906903163&type=3
My guess is Proton will be naming the new P3-21A - Proton Tuah which is part of the Proton Pahlawan Series that they showcased in the 2010 KL International Motor Show.
