Hummer H2 & H3 review






2009 Hummer H2 Review






The 2009 Hummer H2 adds the ability to run on ethanol-blended E85 fuel. This premium large SUV is available as a 4-door wagon and a pickup-like SUT. Like the Chevrolet Avalanche, the SUT features a folding midgate between the cabin and cargo bed. The H2 has an available 2-passenger 3rd-row seat. H2 is powered by a 393-hp 6.2-liter V8 engine. A 6-speed automatic with steering wheel paddles for manual operation is the sole transmission. H2s have all-wheel drive with low-range gearing for off-road use. Off-road equipment designed to cope with severe conditions is available. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. Also standard are OnStar assistance and leather upholstery with heated 1st- and 2nd-row seats. H2's towing capacity is 8000 lb. This report is based on evaluations of the 2008 Hummer H2.


Acceleration

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.
Steering

Massive weight and tall build mean marked cornering lean, though no worse than most large SUVs. Steering feels light at low speeds, yet maneuverability is hampered by jumbo 43.5-ft turning circle (vs. Ford Expedition's 38.7 ft). Not overly sensitive to crosswinds, despite blocky shape, but straightline stability is compromised by huge tires that tend to follow road grooves. Good brake pedal feel and modulation.




2009 Hummer H3 sneak peak




The 2009 Hummer H3 adds a crew-cab pickup truck body style to its roster. Otherwise, the lineup for this off-road-ready midsize SUV should remain largely unchanged. The pickup, called H3T, is larger than Chevrolet's Colorado compact pickup but smaller than the full-size Silverado. Base versions of the H3 wagon retain a 242-hp 3.7-liter 5-cylinder engine. The top-line Alpha sports a 300-hp 5.3-liter V8. The H3T will offer both of these engines, though the V8 is reserved for the H3T Alpha. A 5-speed manual transmission is still standard on 5-cylinder models. Optional on those and standard on the Alpha is a 4-speed automatic. Towing capacity on the 5-cylinder is 3000 lb with the manual transmission and 4500 lb with the automatic. The Alpha has a maximum towing capacity of 6000 lb. H3 and H3T come with all-wheel drive that includes low-range gearing for off-road use. An available Off-Road Adventure Suspension Package on the wagon includes ultra-low gearing and a locking rear axle for severe off-road forays. This feature carries over to the pickup as well. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. GM's OnStar assistance is standard. A rearview camera is available, along with a navigation system. This report is based on evaluations of the 2008 Hummer H3.


Hummer H3T Review


2009 Hummer H3T Review - First Drive
The
Hummer H3Truck? Toss In The Kids, The Dog, And Gear For A Week

Back When the hammer H3 was introduced, we lamented the lack of power from the five-cylinder mill, and the need for additional drivetrain options and a front locking diff. The Hummer guys were listening though, and responded with the H3 Alpha (First Drive, Jan. '08), which sports a 5.3l V-8, but no front locker. But we still wanted bigger tires, regular cogs behind the V-8, a front locker, and maybe even an sUT or a diesel mill. it was only a matter of time before the highly capable H3 followed its genetic destiny. Enter the H3T, a four-door shortbox pickup, with lockers front and rear!
We were fortunate enough to tag along on a recent engineering testdrive where components are validated, yet the looks are camouflaged for secrecy. By the time you read this, the beast will have been exposed, but we're the first to give you our impressions of the new Hummer. While obviously longer than a regular H3, the shortbox can still carry plenty of gear, especially with the tailgate down. The rear camo makes the unit look more like a suburban than a pickup, while the front camo covers up nothing you haven't seen before.
On the blacktop, the additional length of the H3T with its 134-inch wheelbase (23 inches longer that the H3) is immediately noticeable, adding an enhanced feeling of stability at speed. On long grades, the 295-horse 5.3l did as we expected, pulling the additional weight onfidently and without protest. The rigwith the five-cylinder i-5 still required pegging the tach and quick shifts to keep up.
We sneaked this spy rendering of what the showroom model may look like. long? plenty. But for a fully locked and geared rig that can tote a gaggle of kids, a dog, the wife, and your dirt bike in the back, we think it fits the bill.
The only indication of a front locker is the X on the switch-left is rear and right is front. We've been waiting for that switch position to get filled for a few years.
As with the H3 Alpha, the 300hp 5.3l aluminum V-8 will be an option with the H3T, and standard on the Adventure package.
On the trail, our immediate thought was that the 134-inch wheelbase would require a football stadium to do a U-turn. However, the engineering team was two steps ahead of us with a tight-ratio steering box that almost makes turns as tightly as the shorter H3. The flip side of the additional length is a reduced breakover angle and a strong argument for the heavy-duty skidplates. With both lockers engaged, the five-cylinder model mated with the fivespeed worked flawlessly in the rocks, as did the V-8. Both versions of the Adventure package are equipped with the 4:1 transfer case and lockers fore and aft, and provided a solid feel for the terrain. Once we get a chance, we'll test them with the camo off and let you know about visibility as well.
Unfortunately, the H3T will still be burdened with the full array of electronic bells, whistles, bling, curtain airbags, child safety locks, DVD players, satellite babysitters, and other electronic nannies. But the heart of the beast is within, and the fact that you can slip your quad or a ton of gear in the bed, put a couple of kids in the backseat, and have dual-lockers right out of the box is a big plus in our books.

It's Risky To Hand A 4x4 Journalist The Keys To a proof of Concept vehicle (there were only five made), but Hummer likes to work out the bugs in real-world conditions. We quickly found the e-brake cable routed under the frame (and so did a wheelbarrow sized rock), and a tailpipe that is begging for trouble. D'oh!! With the longer wheelbase of the H3T (134 inches), we beat the heck out of the undercarriage. Fortunately, the truck has 1-inch-square tube skidplates that are actually built to take it. The Adventure package also includes heavy-duty rock sliders. if you are going to be doing any modest wheeling, get 'em. Even with good tires and lockers front and rear, the breakover angle of the long truck makes these sliders mandatory off road.
Future Fuels
There are rumblings of additional mill options for 2009 and 2010. yes, flex fuel, or bio-fuel. Working from their r&D facility in Brazil (Brazil leads the world with flex-fuel technology), the Hummer engineers are anticipating the introduction of a flex-fuel H2 for '09, the H3 following suit in '10. We've also seen diesel versions of the H3, but not for the U.s. market-yet. We are still whining about the limited visibility from behind the wheel, and we didn't get the V-8/five-speed stick combo, but there were some serious campfire discussions about removable tops, half-doors, and ragtops.
