Trooper generasi pertama tersedia sebagai wagon tiga pintu atau soft top dengan suspensi depan independen. Model soft-top dijual perlahan dan tidak bertahan lama. Di pasar Jepang, mobil ini awalnya diperkenalkan sebagai "Isuzu Rodeo Bighorn", tetapi bagian "Rodeo" dari nama tersebut segera dihilangkan. Mesin awal termasuk bensin 1,95 liter dan diesel 2,2 liter 73 PS (54 kW), bertenaga ringan bahkan oleh standar awal 1980-an untuk bobot kosong kendaraan 3,700 pon (1,678 kg). Sistem penggerak empat roda diaktifkan dengan mengoperasikan shifter tiga posisi yang berdekatan dengan shifter transmisi. Baik penguncian manual Aisin dan hub penguncian otomatis milik Isuzu digunakan.

Pada tahun 1986, Isuzu memperkenalkan versi lima pintu dan mesin empat silinder 4ZD1 97 PS (71 kW; 96 hp) mesin bensin 2,3 liter. Selain tenaga yang lebih tinggi, perubahan pada mesin sebelumnya termasuk timing belt Kevlar yang menggantikan rantai sebelumnya, dan karburator dua barel yang lebih besar. Mesin ini akhirnya terbukti agak bermasalah dengan insiden tinggi katup terbakar karena desain aliran pendingin yang buruk dari cam overhead/kepala katup dengan pengangkat mekanis.[butuh rujukan] Perbaikan pengecoran kepala kemudian oleh perusahaan Italia memperbaiki masalah ini melalui peningkatan aliran pendingin. Juga tersedia hanya untuk tahun 1986 di AS adalah mesin diesel turbocharged C223T 87 PS (64 kW) 87 PS (64 kW), menggunakan turbocharger Garrett. Itu bukan pilihan yang populer karena daya yang dihasilkan rendah, dan lebih jauh lagi terkenal karena ujung bawah yang lemah, batang penghubung yang awalnya tidak dirancang untuk peningkatan tekanan termal dan mekanis dari induksi paksa. Karena masalah tersebut, Isuzu Amerika Utara berubah ke unit bensin empat silinder 4ZE1 yang lebih besar untuk tahun 1988 dan menggunakan GM V6 2.8 liter standar untuk tahun 1989 sampai mesin V6 baru mereka dapat diproduksi.

Pada tahun 1987, lampu depan persegi panjang diperkenalkan, dan trim LS tersedia untuk lima pintu. Untuk tahun 1988, mesin 4ZD1 (2,3 liter) ditingkatkan menjadi 110 hp, dan memperkenalkan mesin injeksi bahan bakar I-TEC 120 hp (89 kW) 2,6 liter (4ZE1) untuk pasar AS. Pada tahun 1989, sebuah opsional General Motors 2.8 liter pushrod V6 yang dipinjam dari pickup Chevrolet S-10 juga tersedia. Model generasi pertama kemudian menawarkan transmisi otomatis empat kecepatan opsional. Model dari 1988 hingga 1991 dilengkapi dengan as roda belakang hidup dan rem cakram empat roda.

Mesin model luar negeri termasuk Isuzu C223 (2.238 cc), C223T (versi turbocharged yang sama) dan pada akhir 1980-an secara alami disedot dan versi turbocharged 2.8 liter 4JB1 diesel, semua mesin empat lurus. 2.8 liter turbocharged awalnya menghasilkan 95 PS (70 kW), tidak lebih dari 87 PS (64 kW) dari C223T yang jauh lebih kecil karena standar emisi baru yang lebih ketat. Versi yang lebih baru dengan intercooler yang dipasang ditawarkan sebanyak 115 PS (85 kW).[1]

Hanya pada tahun 1989, Isuzu Trooper dengan jarak sumbu roda pendek (90 inci) diimpor ke pasar AS sebagai Trooper RS. Semua Troopers dengan jarak sumbu roda pendek ini dilengkapi dengan mesin 2,6 liter fuel-injected inline-four, roda gigi diferensial 4,77:1 dan roda pola "kepingan salju" paduan aluminium 15x7 inci. Transmisi otomatis dan manual ditawarkan.

Di Amerika Tengah, Troopers ditawarkan dengan atap yang dapat dilepas dan jarak roda yang lebih tinggi. Pilihan powertrain termasuk Isuzu 2.8 liter turbo diesel.

Trooper juga dijual di Australia dan Selandia Baru sebagai Holden Jackaroo, dinamai dari istilah slang Australia untuk seorang pemuda yang bekerja di peternakan domba atau sapi. Trooper standar juga dijual di bawah papan nama Isuzu di Selandia Baru saja. Di Indonesia, di mana ia dirakit secara lokal oleh Garmak Motors, ia dijual sebagai Chevrolet Trooper. Sekitar tahun 1987 versi penggerak dua roda yang disebut Chevrolet Stallion dikembangkan di sana; ia memiliki tubuh Trooper pada sasis Chevrolet LUV berpenggerak roda belakang. Ia juga memiliki poros depan yang kaku, bukan desain independen Trooper. Ada juga model SUV Isuzu Pickup yang dikembangkan secara lokal yang dibangun pada awal 1980-an yang disebut Holden Lincah dan Holden Raider. Meskipun mirip dengan Trooper dalam banyak hal, itu adalah kendaraan yang lebih sederhana dan sebagian bodinya terbuat dari fiberglass. Di Venezuela dikenal sebagai Caribe 442.

Pada tahun 1988, SsangYong Motors memulai produksi berlisensi dari Isuzu Trooper dan menjualnya sebagai Ssangyong Korando.[2] Itu hanya dipasarkan di Korea Selatan, Skandinavia, Asia Tenggara dan pada tingkat yang lebih rendah di Amerika Selatan. Itu menggunakan mesin diesel 2.2 liter yang sama (unit buatan Korea disebut "DC23" daripada C223) tetapi pada September 1991 mesin diesel Peugeot 2.5 liter XD3P yang disedot secara alami juga tersedia.[butuh rujukan] Mesin bensin 2,6 liter injeksi bahan bakar Isuzu juga dipasang, mulai Juli 1991. Pada Agustus 1994 Keluarga Korando menerima facelift, menjadi "Keluarga Baru" dalam prosesnya. Ini juga berarti bahwa semua opsi mesin sebelumnya digantikan oleh mesin diesel Mercedes-Benz OM601 2,3 liter. Keluarga dihentikan pada tahun 1996, sebagai generasi berikutnya Korando disajikan.

In 1991 for the 1992 model year, Isuzu completely redesigned the Trooper to keep pace with changes in the SUV marketplace, making it larger, more powerful, and more luxurious. These 4.155 pon (1.885 kg) vehicles used a 3.2 L 177 PS (130 kW; 175 hp) (SOHC) petrol engine or 3.2-liter dual overhead cam (DOHC) version rated at 193 PS (142 kW; 190 hp). A SOHC 3.2-liter engine producing 193 PS (142 kW; 190 hp) was introduced in 1996, replacing the earlier DOHC engine in selected export markets. Most models still used a part-time four-wheel-drive system, which required stopping the vehicle to engage and disengage the front axle. Starting in model year 1996, some Troopers came with a "shift-on-the-fly" engagement system.

2001–2003 Holden Jackaroo (UBS) SE 5-door (Australia)
1992–1998 Opel Monterey RS 3-door (Germany)

From 1992, the UBS series was available with a pushrod overhead valve (OHV) 3.1-liter inline-four engine intercooled turbo diesel (designated "4JG2") producing 114 PS (84 kW; 112 hp) at 3,600 rpm, and 260 N⋅m (192 lb⋅ft) at 2,000 rpm. It was offered as a more rugged and fuel-efficient option for towing and heavy-duty operation, relative to the standard 3.2-liter petrol. The diesel-powered Jackaroo was available with a five-speed manual transmission and manual front hubs only coupled to a part-time four-wheel drive system with open front and limited slip rear differentials. The 3.2-liter V6 petrol engine version was also available with an optional four-speed automatic transmission with automatic locking front hubs. The same diesel engine was also available in the UK and other markets with a belt-driven overhead camshaft, which developed slightly more power. After 1998, and the introduction of the "4JX1" 3.0-liter diesel engine, a four-speed automatic transmission was made available in addition to the five-speed manual transmission.

The Australian version of the UBS-series was sold as the Holden Jackaroo/Monterey. In July 1993, Holden Special Vehicles also launched 79 HSV Jackaroo models, which were just a cosmetic upgrade to Holden donor powered by the same 3.2-liter 177 PS (130 kW; 175 hp) (SOHC) petrol engine.

Around the same period, General Motors, Isuzu and Honda established a working relationship[5] that saw the two-box design of the 5-door Trooper designed by GM with Honda providing petrol engine options and Isuzu providing diesel engine options. Under this partnership the Trooper was thus sold in Japan as the Honda Horizon (1994 to 1999), in Europe as the Opel Monterey, in the United Kingdom as the Vauxhall Monterey (1994-1998), in Australia as the Holden Jackaroo (1998-2002), and in the United States as the Acura SLX (1996 to 1999). The Trooper received a mid-life facelift in 1998 with new grille, bumper, headlamps, and front fenders. The rear received a body-colored, hard spare-tire cover.[6][7] The 1998 Australasian and US-spec Trooper became equipped with the DOHC 3.5-liter engine from the Isuzu/Holden Rodeo producing 215 hp (160 kW; 218 PS). European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the 4JX1 3.0-liter of 159 PS or 117 kW). A Borg-Warner torque-on-demand ("TOD") all-wheel-drive system was introduced, along with freshened styling. The grille was redesigned again for the 2000 model year.

Transmission options included a five-speed manual transmission, the Aisin AR5[8] and the electronically controlled 4L30E four-speed automatic. The 4l30E was fitted with both a "power" shift feature allowing the gearbox to take better advantage of the engine's power by adjusting the shifting nature and a "winter" mode permitting third gear starts for added stability in slippery conditions.[9] The 2000 to 2002 Trooper included a feature called "Grade Logic" which allowed the transmission to automatically downshift on steep grades in order to slow the vehicle down.

The suspension consisted of a fully independent torsion bar front suspension, and a multilink coil sprung rear suspension integrated with a solid rear axle.

While US-spec Troopers came only equipped with five seats, elsewhere in the world a seven-seater version was also offered. Optional on all models was a rear limited slip differential. In the US the three-door RS model was sold only from 1993 to 1995. The Trooper LS and S models offered 1.178 cu ft (33.360 L) cargo space, while Limited models had 1.123 cu ft (31.800 L).

In 2002, the Trooper was discontinued in the United States in favor of the smaller Axiom and the larger GM-produced Isuzu Ascender, a rebadged GMC Envoy.

A Trooper with the 16-valve 159 PS (117 kW; 157 hp) 3.0-liter 4JX1-TC engine was sold in the Philippines from 2002 until model year 2005. Known as the Skyroof Edition, it came in a rear-wheel-drive configuration with anti-lock brakes, a limited slip differential, billet-type radiator grille, and large power moonroof. Other standard options included leather seats, wood trim, and a VCD entertainment system. It was later succeeded by the Isuzu Alterra.

Acura SLX

 
MY1998–1999 Acura SLX

The "Acura SLX" was a lightly upgraded and rebadged Isuzu Trooper sold by the Acura division of Honda from 1995 to 1999, as 1996 to 1999 year models. Sold only in the United States, the SLX was later replaced by the Acura MDX in 2001.

The SLX omitted some of the options available on Troopers from concurrent model years, including the manual transmission and certain engines. From 1996 to 1997 the SLX was only available with the 3.2-liter SOHC or DOHC V6 engine, switching to the new 3.5-liter DOHC V6 engine in 1998. The SLX received a restyled front end for the 1998 model year, but continued to sell poorly and was ultimately discontinued after 1999. It is said that sales were affected by bad press when the 1996 to 1997 models were rated "Not Acceptable" by Consumer Reports for their tendency to roll over during testing (see Rollover Controversy, below). Autotrader says it has a 3-star safety rating (Front and Passenger) and the base entry price was $36,300.

Monterey

 
1998–2001 Holden Jackaroo SE 5-door

In Europe, the Trooper/Big Horn was sold as an Opel from 1992 to 1999. Called the Monterey, the plate lasted until 1999 on the continent (as an Opel) and from 1994 to 1998 in Great Britain, where the Vauxhall badge was used, but it was not a strong seller and was withdrawn from sale a year before the Opel version on the continent. The Monterey name also saw use by Holden in Australia, at first (from 1994) as the top equipment level (V6 only) for what was there called the Jackaroo, but later as a standalone nameplate for the more luxurious part of the range.

Rollover controversy

The second-generation Trooper received negative press in the United States when the 1995–1997 models were rated "Not Acceptable" by Consumer Reports for an alleged tendency to roll over under testing.[10] In response to a petition from the publication's publisher, Consumers Union, the National Highway Traffic Administration conducted its own tests and found no issue that could lead to a need for a recall.[10][11] However, Isuzu suggested that the magazine's claims had hurt sales of the vehicle.[12]

 
2001–2003 Holden Monterey (Australia)

After the release of the NHTSA report, Isuzu filed a lawsuit against Consumers Union seeking $242 million in damages, claiming that during Consumer Reports's tests the steering wheel had been twisted more sharply than "a driver is willing or able to make in response to an unexpected event.[11] The judge in the suit, Richard Paez, determined that because Isuzu had engaged in an extensive public relations campaign to refute the claims prior to filing suit, it was considered a public figure, raising the standard for defamation from a simple preponderance of evidence that the report was false to "clear and convincing evidence" that Consumer Reports published the article knowing it was false or with reckless disregard for whether it was true or false.[13] The defamation suit went to a jury, which found that eight of the 17 statements in the report questioned by Isuzu were false, with one displaying "reckless disregard" for the truth on the part of Consumer Reports magazine, but that Isuzu was not damaged by that statement.[14][15] Two of the ten jurors on the panel did not believe the magazine believed that the other seven statements were untruthful when they published them.[14] Consequently, the full jury panel did not award Isuzu monetary damages for the alleged damage to its reputation and lost sales.[14] Isuzu calculated the total cost of the Consumer Reports claims at $244 million.[16] As Isuzu was denied damages on all counts, the formal court judgement in favor of Consumers Union entered by Paez required Isuzu to pay CU's "reasonable costs" of defending itself against the suit, not including attorney's fees.[17]
