More power is the word for 2004. The Axiom's 3.5-liter V6 engine features new gasoline "direct injection" technology to improve both horsepower and torque. Of a less exciting nature, the audio system doesn't include a tape player anymore and the speaker count drops by two for a total of six. Outside, there's a new chrome finish for the front grille and for the XS model's optional alloy wheels.
