Overview

A new mode, Tag Battle, was introduced. Like its predecessor, the game saw a change in its driving physics. A drift gauge and an updated tachometer was introduced to help inform players whether they're drifting or not. The tachometer now inform players if their speed is below the gear range. Online network is extended to support regions in which earlier versions of the game was known to be popular in, finally achieving both national wide and international matches. For the first time in series, new cars and courses are added to the game through online updates without upgrade kits like IDAS4 1.5. The game also added a mileage system to show players their total driven mileage. Mileages can be used to redeem exclusive cars that were later available in updates.
