Although I'm looking for a 4WD, I had trouble finding specifications that could be compared. All the numbers below are for 2WD. The Chevy ratings are in back-to-back years with the 5.7L.
- Chevy Suburban GMT800 00 12/17 mpg
- Chevy Suburban GMT400 99 12/17 mpg
- Chevy Tahoe GMT800 00 12/16 mpg
- Chevy Tahoe GMT400 99 12/16 mpg
- Dodge Durango 00 4.7L 13/18 mpg
The mileage ratings did not change from the 99 GMT400 to the 00 GMT800 for the Tahoe or the Suburban. I suppose I would seek the newest possible version, but a few thousand dollars in savings would allow for more improvements over stock. |
I'd double-check that.
1999 had the 5.7L (Gen II small-block V8)
2000 had the 4.8L/5.3L/6.0L (Gen III small-block V8)
The 4.8L made more power than the 5.7L, but was rated at 13/18 in 2000 and 14/19 in 2005+
If you are finding specs for the 5.7L in 2000 it is probably the GTM400 Tahoe that they had a limited run of for 2000. GM likes to do that when they switch body styles.
2005 had some small aero improvements and electric fans. So, the '05-06 Tahoe is probably your best bet. Also, the EPA numbers don't account for optional gear ratios.
I bought my wife a Tahoe and picked it specifically for optimal fuel economy. 2005, 2WD, 4.8L, high gear ratio. She has a heavy foot and gets 13-15mpg city, 22-25mpg hwy.
