Example, C&D tested a 2010 FWD Enclave.
Curb: ~4900 lbs
0-60: 7.4s
1/4 mile: 15.9s

C&D tested a 2009 AWD Traverse
Curb: 4954 lbs
0-60: 7.6s
1/4 mile: 15.9s@88mph

C&D teested a 2007 AWD Acadia
Curb: 5052 lbs
0-60: 8.1s
1/ mile: 16.4@85mph

C&D tested a 2010 4Runner Trail
Curb: 4780 lbs
0-60: 7.8s
1/4 mile: 16.1s@88mph

The C&D data says the Lambdas keep up with the 4Runner when you account for curb weight (F=ma).

It looks like the 4Runner kicks the Lambdas around, but the base 2WD 4Runner is ~15% lighter than the GMs. Also, if you look at the test report, the 4Runner was tested when it was 54 degrees. The two Lambdas were tested when it was 83, that's about a 6% difference in density altitude (the 4Runner will make more horsepower). Taking weight and air density into account, the two vehicles are equal again.



Hopefully our 4Rrunner will loosen up and get some summer gas in her in a bit to get the mpg up past 20. So far, the 4Runner is the only vehicle I've ever driven that gets less than the EPA sticker number. The rental Acadia was one of many that beat it.
