If your foot is heavy you'll pay for every thrill. With a lighter touch you can actually eke some good mpg's out of the 3L V6. |
| 2001 | 4dr Sedan 227-horsepower 3.0L V6 4-speed automatic FWD |
For what it is, it gets pretty low city MPG for a Japanese car. Around 15-17 depending on conditions. Highway gas mileage is good though |
