While the entire range benefits from the new look and improved interior options, the big news is that the WRX offers even better performance, thanks largely to a new "Active Valve Control System".
Essentially this is a VVT system, which electronically adjusts the intake valve timing, in turn producing more power and torque while at the same time minimising fuel consumption and emissions.
The superceded MY02 WRX offered an impressive 160kW of power @ 5600rpm and 292Nm of torque @ 3600rpm.
Combine this with Subaru's patented all wheel drive system and the '02 WRX accelerated from 0-100km/h in just 6.4 seconds, completing the 1/4 mile dash in 14.6 seconds.
The 2003 WRX, however, goes from 0-100km/h in 5.7 seconds and covers 400m (1/4 mile) in 13.9 seconds, according to Subaru Australia.
