2009 Hummer H2 Performance
This performance review was created when the car was new. Some links may no longer point to an active page.
Reviews say that though the H2 is almost unbeatable off-road, on pavement there are much more comfortable and useful rides.
- "Street driving is like square-dancing with a fat person; don't expect miracles. The 6.2-liter makes it fast for its size, but handling is elephantine and visibility poor. Belongs off-road." -- Car and Driver
Acceleration and Power
The Hummer H2's engine and transmission are borrowed from the Cadillac Escalade and the GMC Sierra Denali, and many reviewers remark that the component sharing shows that GM was serious about turning the H2 into a complete luxury SUV package. For 2009, the 6.2 liter V8 engine gets flex fuel capability. A six-speed automatic transmission is standard, and most reviewers say it works well. The only problem with the powertrain is it's appetite for fuel. Because of its weight, the H2 is exempt from EPA fuel economy testing.
- "Underneath the hood is a robust 6.2-liter V8 that's powerful enough to motivate all of the H2's 6,600-plus pounds." -- Edmunds
- "Acceleration is fairly brisk around town and strong at highway speeds. Hummer estimates an 8.0-second 0-60 mph time, which feels accurate to us. The smooth-shifting transmission is prompt to kick down for more power." -- Consumer Guide
- "On the open road, the powerful H2 moves right along, seemingly oblivious to the laws of aerodynamics." -- Kelley Blue Book
- "The H2's V-8 engine is responsive and doesn't feel heavily taxed during normal driving by the SUV's substantial 6,614-pound curb weight." -- Cars.com
- "As for the transmission, the addition of a six-speed is sheer brilliance. . . No matter what your function, the six-speed gives you lots of options." -- Chicago Sun-Times
Handling and Braking
Most reviews say on road, the H2's handling is pretty good, considering its size and weight. However, compared to others in its class, the H2 can be difficult to drive on a day-to-day basis.
- "The big HUMMER is surprisingly stable and the positions of the wide 17-inch tires at the vehicle's outermost corners means you get minimal body roll and fairly respectable handling. This accolade, however, must be taken in context, since we are talking about the handling of a Sport Utility Vehicle, not a sports car" -- Kelley Blue Book
- "Back on city pavement, however, the H2's demeanor is a bit like an overloaded rolling suitcase in a crowded hallway being pushed by an NFL linebacker -- unwieldy and awkward, but its massive proportions are enough to intimidate its way past nearly anything else." -- Edmunds
- "If you're considering an H2 you're probably well aware that you're getting a full-size body-on-frame SUV. With this design come certain driving characteristics, like noticeable dive when braking." -- Cars.com
Most reviewers say the 2009 Hummer H2 has few rivals on the trails, writing the Hummer's signature brick shape makes for great approach and departure angles.
- "Hummers have always been astounding off-road. . . An upgraded cast-iron transfer case was fitted to handle the extra torque. The transmission's gear spread allows more flexibility in rock-crawling both in the form of a higher top speed in low range, as well as a lower crawl ratio in first." -- Car and Driver
- "The 2009 Hummer H2 excels off-road with its lofty ground clearance, steep angles of approach and departure, long suspension travel and tenacious tire grip." -- Edmunds
- "For off-road adventuring, including steep hill encounters and boulder-climbing, the transfer case can be locked, creating a perfect 50/50 distribution of power. A four-channel anti-lock brake set-up and traction control module help limit wheelspin on slippery or unstable ground, and can even route power to a single wheel when necessary." -- Kelley Blue Book
- "It's hard to find a vehicle anywhere that can roll over rugged terrain the way an H2 can, and for those of us who enjoy trail driving, the Hummer is a great option." -- Fort Worth Star-Telegram
