Test Driver Ratings & Comments
Acceleration commentsDespite a CVT-like transmission, the Tahoe's revs climb rapidly to 5,000 rpm (as if in 1st gear) and then drop to about 4,000 rpm for the remainder of the quarter-mile. The engine sounds annoyed throughout.
Braking ratingGood
Braking commentsMedium-soft pedal goes hard at the end of travel. I could hear the tires howl and feel them hunt for traction. Also, the weighty job of stopping this 6,000-pound Tahoe is obvious.
Handling ratingAverage
Handling commentsSlalom: With StabiliTrak off, I did the first few runs in rear-wheel drive (2WD) and found it felt like slaloming a limo with slow-mo oversteer. Switched to "Auto 4WD" and was able to quell the oversteer somewhat. Still, this thing feels heavy, ponderous and out of its element in any handling test. Steering is numb but rather precise. Skid pad: Heavy, tire-torturing understeer right on the threshold. StabiliTrak can be shut off completely. Steering feels a little springlike with little feel.
