Test Driver Ratings & Comments

Acceleration commentsLike its Toyota cousin, the GX's 4.7-liter V8 produces solid torque and almost leaps off the starting line. But also like its cousin the engine doesn't offer much top-end rush. The GX was about two-tenths slower through the quarter-mile than the V8 4Runner we recently test, but adjustable suspensions and Mark Levinson amplifiers aren't known for their light weight, so this is to be expected. There is no way to easily shift the automatic transmission due to the convoluted shift gate pattern, so the best times come from just leaving it in Drive.
Braking ratingExcellent
Braking commentsBraking power was strong, with the GX coming to a halt in 130 feet (a short distance for a 4,700-pound truck). Brake pedal action was progressive and ABS kickback non-existent. This vehicle weighs more than a 4Runner but stopped slighty shorter than that vehicle. The pedal also had a more confident feel, so if you're thinking the GX is just a rebadged Toyota...well, you're still right, but it certainly stops better than the lower-cost version.
Handling ratingGood
Handling commentsOur previous experience with Toyota's 4Runner was mirrored here. Specifically, the VSC made it difficult to get the GX through the slalom as rapidly as we would have liked. This electronic nanny cannot be defeated, so the fastest times come from balancing the SUV between aggressive turn-in and VSC intrusion. I did manage a slightly better time in the Lexus than the Toyota, and that can likely be attributed to the adjustable suspension, which I set at max "sport" mode for slalom testing. A faster slalom speed is possible...but not without cutting some VSC sensor wires. — Karl Brauer
