HUMMER 2





Overview

Two years ago, the Hummer H1, based on the military Humvee, was joined by the all-new Hummer H2. The H2 is based on GM's heavy-duty pickup trucks, but highly modified for increased off-road capability. Longer and taller than the original H1, the H2 is built at a new plant in Indiana. For 2005, the Hummer H2 SUV is joined by a second model called the SUT or Sport Utility Truck.

The SUT version, as its name implies, is a pickup, not an SUV, characterized by its unique tailgate, short pickup bed, and tailgate-mounted full-size spare tire, which makes it a few inches longer than the SUV overall. The SUT features GM's innovative Midgate, which quickly converts the five-passenger SUV with a small pickup bed to a two-seat pickup with six-foot bed.

The Hummer H2 offers truly impressive off-road capabilities. And unlike the H1, it provides occupants with a luxurious interior that's comfortable and convenient. Its size and design makes suitable for everyday use, as long as you have a large gasoline budget.

HUMMER H1 Alpha












HUMMER H1 Alpha

Powered by GM's Duramax 6600 turbodiesel engine, the 2006 Hummer H1 Alpha generates an impressive 300 horsepower at 3,000 rpm and an incredible 520 lb.-ft. of torque at 1,500 rpm. A new Allison 1000 five-speed automatic transmission supplies the H1 with a tow/haul mode, a 2,000-pound bump in Gross Combined Weight Rating (GCWR) to 17,300 pounds, improved drivetrain braking, and a 22-percent better crawl ratio of 45:1 for the really tough stuff. To make room for the new motor, the 2006 Hummer H1 Alpha's body sits two inches higher than before. All H1 Alphas get bigger brake rotors; upgraded axle half-shafts; tougher steering gear; and redesigned wheel hubs with a helical-cut gearset that improves gear engagement while reducing driveline noise and rocking motions when slowing down or stopping. To identify the 2006 Hummer H1 Alpha, look for this model's brighter finish wheels and special "Duramax" and "Alpha" badges on the body. Like last year's H1, the Alpha rides on 37-inch Goodyear GSA light-truck run-flat tires that can go 20 miles without air.

Advantages of the 2006 HUMMER H1 Alpha:

  • Awesome off-road capabilities
  • Undeniable street presence
  • Stump-pulling torque

Objections to the 2006 HUMMER H1 Alpha:

  • Cramped cabin

Mitsubishi Pajero 4x4




Mitsubishi Pajero 3.5 GLS 4x4



A strong heritage can be both a blessing and a curse. In choosing from the huge clutter of turf-tackling wagons on the market these days, an SUV with the Mitsubishi Pajero's illustrious history comes with ready-made credibility, but it can also create unreasonably high expectations.

The Pajero's successful off-road exploits, including several Dakar victories, have successfully wooed adventure-spirited motorists all over the world since its launch in the early 1980s.

The style and all-terrain versatility that made its predecessor a best-seller is recreated in the latest Pajero - launched here in May in a six-model range of short- and long-wheelbase derivatives - but not without some flaws.

A stint behind the wheel of the GLS 3.5 litre long-wheelbase version revealed notable improvements over the old Pajero but with some drawbacks that peg the newcomer a half-notch lower than the top SUVs.

DESIGN

A big SUV such as a Pajero can be the best cure for the urban blues. Clambering through the undergrowth in a 4x4 can sterilise the stress of a manic week spent with kamikaze minibuses and fast-lane dawdlers, which is probably why the SUV market has grown so rapidly over the past few years.

Mitsubishi's latest bundu brawler is a broad, comfortable rig with eye-catching styling and big muscle that ferries up to seven passengers over all sorts of territory.

A monocoque body is the most significant change to the newcomer, replacing the previous truck-like ladder frame chassis with a unitary body that has increased torsional strength, improved cabin room and lowered the centre of gravity.

All very nice, but let's get down to basics: the Pajero's flashy posing power alone will be more than enough to elicit a down-payment from many SUV aspirers.

With its art-deco lights and belligerent body armour, the Pajero looks like a cast-off from the WesBank Modified challenge and if standing out is your thing, the Mitsubishi's the Naomi Campbell of the urban jungle catwalk.

INTERIOR

This eye-catching design flair continues into the stylish cockpit, a tasteful flamboyance with lots of nice touchy-feely bits such as the dimpled finish on the steering wheel, door handles, gearlevers and handbrake.

Broad, comfortable leather-clad seats take care of the passengers, and take the punishment out of driving over harsh surfaces.

Cabin room has grown over the previous generation and is simply enormous. Excellent passenger/cargo versatility comes from a back seat that can be stored in the underfloor compartment to provide unhindered luggage space, or removed if the underfloor area is also required, while the middle seats fold forward.

Gone are the altimeter and incline gauges that perched atop the old Pajero's dash, but there's a trip computer with useful info to scroll through, such as outside temperature, audio information, average speed and fuel consumption.

Ergonomics are first-class, with the radio and ventilation controls high-mounted for easy reach, while the steering wheel is height-adjustable and the driver's seat has electric controls.

The array of gimmicks and comforts rivals any luxury limousine, and includes cruise control, a CD sound system, and automatic climate control with separate ventilation controls for the rear passengers.

PERFORMANCE

Two engines are available: a 16-valve 3.2 diesel and a 3.5 petrol 24-valve V6. The petrol V6 and five-speed transmission of our test vehicle coped admirably with lugging such a big piece of SUV around. In fact, this Pajero is one of the brawniest 4x4s available and has healthy power on tap, whether cruising the fast lane or sprinting from the traffic lights.

The mighty Mitsubishi eats up the Reef's 0-100km/h sprint in just over 11 seconds, a superb feat for a two-ton Tessie and likely to cause some red faces among the pocket-rocket brigade. The only SUV that outguns it is the 4.7-litre V8 Jeep Grand Cherokee, at 9.7 sec.

Similarly impressive is the efficiency of the braking, with anti-lock assistance helping bring the heavy behemoth from 100km/h to rest in only 3.2 seconds.

HANDLING

All-independent suspension replaces the previous independent front and solid rear axle setup while the wheelbase and track width have grown. All this has transpired in an effort to improve handling but the long-wheelbase Pajero is a soggy, unwieldy beast on the tar, with a vague steering action.

Unfortunately, the net result was a roll-over when we flicked the Mitsubishi into a tight corner at Gerotek's ride and handling circuit.

It simply cocked its wheels like a dog at a lamp post and tipped on to its right side when we simulated an emergency lane change - a worrying occurrence as a vehicle's not supposed to fall over simply by driving into a bend too fast, and usually needs to be tripped-up by something like a kerb or a ditch.

We believe the culprits were a too-high centre of gravity coupled with very grippy tyres.

OFFROAD

The Pajero's off-road prowess helped raise its estimation somewhat but here, too, it ran into some obstacles.

The impressive bit is Pajero's trademark Super-Select all-wheel-drive system, one of the best in the business for its near-effortless convenience.

It allows you shift-on-the-move between two and all-wheel-drive at speeds up to 100km/h and back at any speed and has four modes: standard rear-wheel-drive, al-wheel-drive in high range, plus high and low-range modes with the centre differential locked.

There is pretty much enough traction to get you scrambling up the most slippery and bumpy hill, churn through squishy riverbeds and sail effortlessly over axle-twisters.

Unfortunately, little praise can be levelled at the long-wheelbase Pajero's departure angle when climbing a sharp slope and the bottom of the rear chassis was often snagged during our off-road test. Pity, as it means the Pajero will risk some damage if it tries to play follow-the-leader with the likes of a Range Rover, Patrol or Grand Cherokee in very rocky and mountainous terrain.

Land Rover Discovery




Land Rover Discovery

Land Rover redesigned its lower-priced model for 1999, giving it a Series II designation. Appearance did not change appreciably, but the new model was claimed to be 85 percent new. It was the first revamp since the Discovery's debut in 1994. Overall length grew by 6.5 inches and width by nearly 4 inches, but the wheelbase was unchanged. Only a single version of the four-door midsize SUV was offered, with several class "firsts." Although styling remained familiar, the Discovery had more rounded contours and a taller windshield. A newly designed dashboard went inside, along with softer and larger front seats. Equipped with permanent four-wheel drive and standard five-passenger seating, the Discovery II held a 4.0-liter V8 engine and four-speed automatic transmission. Engine output rose by 6 hp and torque by 18 lb-ft, compared to the prior model. If optional 3rd-row seating was requested, the jump seats now faced forward instead of inward. Cargo space behind the middle bench went up by a claimed 15.5 cu ft. Cloth upholstery was standard, with leather optional. Automatic dual-zone climate control also was standard. Antilocking all-disc brakes and 16-inch wheels were standard. The 4WD system had separate low-range gearing and electronic traction control that braked individual wheels as needed to limit spin in severe conditions and restore lost grip. Standard Hill Descent Control automatically applied brakes to limit speed when descending steep grades in Low range. An optional Active Cornering Enhancement (ACE) system replaced the usual antiroll bars with hydraulic rams, to reduce body lean in hard turns. A self-leveling suspension also was available. At this time, the Land Rover organization was a subsidiary of BMW. Rivals to the Discovery included the Ford Explorer, Acura MDX, Lexus RX 300, Mercedes-Benz M-Class, and Infiniti QX4.

SUZUKI SAMURAI




Samurai

The Samurai was introduced to North America in 1985 as a 1986 model. It had a 4-cylinder 1.3 liter engine that produced 63hp and was available as a convertible and a hardtop. The Samurai was priced at $6200 and 47,000 were sold in the first year alone.

The 1988.5 model Samurai was revised with the addition of fuel injection and it then produced 66hp. The revision also included softer suspension settings and a larger anti-sway bar to reduce body roll. The Samurai was withdrawn from the United States market in 1995 due to low sales. The disputed 1988 rollover report by Consumer Reports (see below) was recognized as the cause.

1996

The Samurai continued for sale outside the United States, with a substantial update in 1996. This included a coil spring suspension, though the live axles were retained. The rest of the truck was redesigned as well, with new seats, dashboard, steering wheel, and doors joining a "macho" exterior.

Not all SJ models were updated however, with the original narrow SJ410 still in production in some areas. Even though the Jimny replaced the SJ in most markets after 1998, the SJ remains in production today.

Consumers Union and the Suzuki Samurai Lawsuit

Suzuki alleges in its product disparagement lawsuit against Consumers Union (CU) that CU rigged the tests for its "Not Acceptable" rating of the Suzuki Samurai in the spring of 1988 and then exploited that false evaluation for financial gain.

Suzuki filed suit in April 1996 after CU repeated and sought to further capitalize on its unfounded claims. Specifically, in its 60th anniversary issue, published in January 1996, Consumer Reports magazine singled out the Suzuki Samurai as the prime example of a "Not Acceptable" safety hazard that the magazine prides itself on exposing. CU bragged to its readers that its tests showed "the Suzuki Samurai easily rolls over in turns." Suzuki has challenged these statements - and similar ones made around 1996 -and contends that CU knew they were false when published.

The case was dismissed by the U.S. District Court in Santa Ana, California, in May 2000 and Suzuki appealed to the U.S. Court of Appeals for the Ninth Circuit. The issue before the Ninth Circuit is whether enough evidence exists to take this case to a jury on the issue of whether CU acted with actual malice when it republished its Samurai statements, i.e., whether it made the statements with knowledge of falsity or with a reckless disregard of the truth.

Land Rover Defender




The biggest change to the Land Rover came in late 1990, when it became the Land Rover Defender, instead of the Land Rover Ninety or One Ten. This was because in 1989 the company had introduced the Discovery model, requiring the original Land Rover to acquire a name. The Discovery also had a new turbodiesel engine. This was also loosely based on the existing 2.5-litre turbo unit, and was built on the same production line, but had a modern alloy cylinder head, improved turbocharging, intercooling and direct injection. The 200Tdi as it was called produced 107 hp (111 in the Discovery), and 188 lb·ft of torque (195 lb·ft in the Discovery), which was nearly a 25% improvement on the engine it replaced. The reason for the engine being detuned was to reduce engine stress and improve service life under prolonged periods of high engine speeds, such as when engaged in heavy towing, which the company reasoned were more likely to be encountered with a utility Land Rover than with a Discovery.
This engine finally allowed the Defender to cruise comfortably at high speeds, as well as tow heavy loads speedily on hills while still being economical. At a stroke Land Rover removed all the other engine options (now redundant in the face of such a good package in a single engine). Some enthusiasts consider the 200Tdi to be the best engine fitted to the vehicle.
1994 saw another development of the Tdi engine, the 300Tdi. This was the same capacity, and both the Defender and the Discovery had engines in the same state of tune (111 ho, 195 lb·ft), and had the same basic layout, but had over 200 changes to improve the refinement and on-road performance of the engine. However, in the process the economy of the engine was reduced slightly, as was the ability for it to be serviced by the owner.
Throughout the 1990s the vehicle climbed more and more upmarket, while remaining true to its working roots. If ordered without any optional extras, the Defender was a basic working tool. If the owner wanted, any number of accessories could transform it into a vehicle that was perfectly acceptable as an everyday method of transport, while still retaining excellent off-road abilities. This was epitomised by the limited edition 50th Anniversary Defender 90 from 1998 which was equipped with automatic transmission, air conditioning, roll-over protection cage and powered by the Range Rover 4.0-litre V8 engine.
