The Evolution VI's changes mainly focused on cooling and engine durability. It received a larger intercooler, larger oil cooler, and new pistons, along with a titanium-aluminide turbine wheel for the RS model, which was a first in a production car. The Evolution VI received new bodywork yet again, with the most easily noticeable change being within the front bumper where the huge fog lights were reduced in size and moved to the corners for better airflow. A new model was added to the GSR and RS lineup; known as the RS2, it was an RS with a few of the GSR's options. Another limited-edition RS was known as the RS Sprint, an RS tuned by Ralliart in the UK to be lighter and more powerful with 330 hp (246 kW).
Yet another special edition Evolution VI was released in December 2003: the Tommi Mäkinen Edition, named after Finnish rally driver Tommi Mäkinen who had won Mitsubishi four WRC drivers championships. It featured a different front bumper, Red/Black Recaro seats (with embossed T. Mäkinen logo), 17" Enkei white wheels, a leather Momo steering wheel and shift knob, a titanium turbine that spooled up more quickly, front upper strut brace, lowered ride height (with tarmac stages in mind), and a quicker steering ratio. Amongst other colours, the Evo VI came in either red (Tommi Mäkinen Edition only), white, blue, black or silver with optional special decals, replicating Tommi Mäkinen's rally car's colour scheme. This car is also sometimes referred to as an Evolution 6½, Evolution 6.5, or TME for short.
