Adequate may not be a glowing endorsement, but it’s the best way to describe the Avenger’s 2.7-liter flex-fuel V6. Working with a four-speed automatic transmission, the 189-horsepower six-cylinder accelerates well and allows for worry-free highway passes, though by no means does it transform the Avenger into a stealth sport sedan. However, the performance is perfectly acceptable for a mid-grade family sedan. Refinement could be upped a notch, though the sound and feel are superior to the overall graininess of the Pontiac G6’s 3.5-liter V6. Torque steer is largely absent, and the four-speed automatic transmission is usually smooth in its operation. The SXT lacked a trip computer to gauge fuel economy, but the EPA estimates a return of 19/27 mpg.
