The Isuzu MU is a mid-size SUV which was produced by Japan-based manufacturer Isuzu from 1989 to 2004.
The three-door MU was introduced in 1989, followed in 1990 by the five-door version called Isuzu MU Wizard. Production of these first generation models ceased in 1998 to be replaced by a second generation. This time, the five-door version dropped the "MU" prefix, to become the Isuzu Wizard. The acronym "MU" is short for "Mysterious Utility". Isuzu manufactured several variations to the MU and its derivates for sale in other countries.
The short-wheelbase (three-door) version was sold as the Isuzu MU and Honda Jazz in Japan, with the names Isuzu Amigo and later Isuzu Rodeo Sport used in the United States. Throughout continental Europe, the three-door was called Opel Frontera Sport, with the Vauxhall Frontera Sport title used in the United Kingdom, and Holden Frontera Sport in Australia.
The long-wheelbase (five-door) version was available as the Isuzu Wizard in Japan, and in North America as Isuzu Rodeo and the Honda Passport. Opel, Vauxhall, and Holden each also sold rebadged versions of the five-door as the Opel Frontera, Vauxhall Frontera, and Holden Frontera. It was also sold as the Chevrolet Frontera in Egypt, the Isuzu Cameo and Isuzu Vega in Thailand, the Isuzu Frontier in South Africa, and as the Chevrolet Rodeo in Ecuador, Colombia and Bolivia.__TOC__

The three-door Isuzu MU made its debut in Japan during 1989, with the five-door MU Wizard introduced the following year. Based on the Isuzu Faster (TF) pickup truck of 1988, both the three- and five-door models shared bodywork and most internal components from the front doors forward. Like the Faster pickup, the MU and MU Wizard featured rear- and four-wheel drive layout configurations.
Between 1993 and 1996, Honda retailed three-door versions of the MU under the name Honda Jazz for the Japanese market under a model sharing arrangement that resulted in several Isuzu models being badged Honda and vice versa.
Isuzu introduced the five-door Isuzu Rodeo to the United States in 1990 for the 1991 model year. It was available with either a 2.6-liter inline-four engine rated at 89kW or a 3.1-liter V6 engine made by General Motors (GM) which had the same power output as the 2.6, but had more torque. An automatic transmission was available for the V6. The Rodeo, like the Amigo was available in both RWD and 4WD, with the latter featuring manually locking hubs on the S version and automatically locking hubs on the XS and top-of-the-line LS. Rear-wheel ABS were standard feature on 4WDs. A RWD manual transmission model with a 21.9usgal tank was rated at 18mpgus in city driving by the EPA, and 22mpgus on the highway. A 4WD model with the V6 and automatic transmission was rated at 15mpgus city and 18mpgus highway.
All Rodeos had a rear seat bottom which folded forward and rear seat back which folded down, extending the 35cuft cargo area. The vehicle's lug wrench was stored under the seat bottom, concealed by a carpeted Velcro flap. The jack was located behind a plastic panel in the rear left of the cargo area along with the rear windshield washer fluid reservoir if equipped. The LS was available with privacy glass, velour upholstery, and split-folding rear seats. A secret locking compartment was fitted in the depths of the center console below a removable cassette storage bin. The vehicle weighed 3490lb3820lb, depending on engine and options.
For the 1993 model year, Isuzu replaced the GM V6 engine with their own 3.2-liter 24-valve SOHC V6 which was rated at 130kW. Manually locking hubs were eliminated, but the floor-mounted transfer case shifter remained. The 1993 Rodeo featured a recalibrated suspension system, softened spring rates and softened shock valving. The Rodeo now weighed between 3536lb4120lb and the EPA rating was 18mpgus city and 21mpgus highway. Also for 1993, a Family II 2.4 litre four-cylinder engine from Holden was introduced, and the Rodeo gained a third brake light above the rear window and a more refined center console. The "V6" badge on V6 models was moved behind the front wheels. Midway through 1995, the Rodeo received an updated dashboard and steering wheel, both of which added airbags. The "ISUZU" badge on the front grille also shrunk in size. For 1996 Isuzu increased the power of their 3.2-liter V6 up to 145kW and 262Nm of torque, and the top level trim LS received the same 16-inch aluminium wheels as the Trooper, and was available in two-tone exterior colors.
Isuzu sold 24,612 Rodeos in 1991 and 45,257 Rodeos in 1992.[2] US models were manufactured at Subaru-Isuzu Automotive, Inc. (now, Subaru of Indiana Automotive, Inc.) in Lafayette, Indiana. The vehicle was still considered an import, as 75 percent of its parts were made overseas.[3]
The first generation Isuzu Rodeo and its twin, the Honda Passport received a rating of "Poor" in the IIHS frontal offset test conducted at 40 mph due to a poor safety cage and dummy movement, and excessive footwell intrusion that contributed to injuries to both legs.
This series was known in the United Kingdom as the Vauxhall Frontera and in the rest of Europe as the Opel Frontera. It was launched in November 1991 and built at the former Bedford van factory in Luton, England; it would become known as the IBC factory (Isuzu Bedford Company). In the 1980s the plant had come under joint control between Isuzu and General Motors, with the Frontera being built alongside a number of other commercial vehicle models. The Australian and New Zealand version of the model range was known as the Holden Frontera and these were also produced at the Luton facility. The Frontera was Vauxhall's answer to the growing demand for 4X4 vehicles in Europe - particularly the right-hand drive British market - during the 1980s, where Japanese imported products from Daihatsu, Mitsubishi, Nissan, Suzuki and Toyota had proven hugely successful, not to mention the success of the long-running British Land Rover and Range Rover. Despite the vast and growing competition in the 4X4 market, the Frontera sold well throughout Europe.
The early cars (to 1995) had a choice of engines, with the LWB available with either a 2.4-liter petrol (C24NE) engine (developed in the Opel Manta i240) or the 2.3-liter diesel (23DTR) engine originally fitted in the Bedford CF van and Vauxhall Carlton. The Frontera sport (Isuzu Amigo) was available with the 2.0-liter petrol Vauxhall Cavalier engine (C20NE).
In 1995, the model went through a facelift and the Frontera received rear coil springs and a new line up of engines. The SWB gained a new 2.0-liter petrol (X20 series) engine, updated trim, and also the first diesel engine available for the SWB, the 2.8-liter (4JB1-TC). The LWB also had new engines, with the 2.2-liter petrol (X22SE) and the 2.8 diesel 4JB1-TC being made available.
In the 1996–1997 models interior trim, including the dashboard, was changed, and a new 2.5-liter diesel (VM41) engine was fitted. This engine was also used in the Range Rover Classic and Jeep Cherokee in the UK.
A redesign took place in 1998, and the Frontera was produced in Britain for a total of 13 years until it was finally discontinued in 2004.
In October 1995, Holden of Australia and New Zealand introduced the MU under the Holden "Frontera" badge in Australia and Holden "Wizard" badge in New Zealand. Designated the UT or M7 series, the Holden was based on the three-door body and manufactured in the United Kingdom.[4] It was offered in one level of trim, the "Sport 4×4", offered solely with a manual transmission.
For the Thai market, the MU Wizard was sold as the Isuzu Cameo (1993–1996) and Isuzu Vega (1999–2004) in Thailand. The Cameo using a 2.5-liter 4JA1 diesel direct injection engine, producing 900NaN0 at 3,900 rpm and the maximum torque of 17.80NaN0 at 1,800 rpm[5] came standard. The transmission was 5-speed manual with rear wheel drive only. The equipment is the same as in the TF and the only body style available is a five-door wagon. In 1999, Isuzu Thailand decided to have a major change for Cameo and gave it new name Vega, equipped with four-wheel drive only. Exterior differences from Cameo including the new frontal design, halogen headlights, 15-inch wheels with 265/70R15 tires and the spare wheel on the back door. It was introduced with 2.8-liter engine 4JB1-T and the brand new 3.0-liter 4JH1-T turbodiesel, producing 1200NaN0 at 3,800 rpm and maximum torque of 24.50NaN0 at 2,000 rpm,[6] because of the development of the CCI (ISUZU Computer Controlled Injection) and HPI (ISUZU High Pressure Fuel Injection). In addition, it connected with a choice of 5-speed manual and "Technomatics" 4-speed automatic controlled by the TCM system (Transmission Control Module). The driver can manually choose style of driving by "Normal mode" and "Power mode".

In September 1997, the second-generation MU (three-door) and Wizard (five-door; now with "MU" prefix dropped) were shown at the Tokyo Motor Show, with Japanese sales starting May 1998. North American and European sales began shortly thereafter.
In 2004, Isuzu added the optional 3.5-liter V6 gasoline direct injection (GDI) engine with 250hp and 246lbft of torque. Isuzu was the first to offer (GDI) in a vehicle priced under US$100,000. The Rodeo weighs in at a little over 3800order=flipNaNorder=flip, with an EPA estimated gas mileage for 2007 of 16mpgus city and 22mpgus highway for the two wheel drive model, and 15mpgus city and 20mpgus highway for the four wheel drive model.
The second generation Isuzu Rodeo and its twin, the Honda Passport received a rating of "marginal" in the IIHS frontal offset test conducted at 40mph due to a possible injury to the right leg and the head, but dummy movement was reasonably well controlled.
The Amigo made a comeback in the US for 1998 after a three-year hiatus with the second generation model alongside the redesigned Rodeo. The Amigo was originally only available only as a soft top with a five-speed transmission. Standard rear-mounted spare tire, ABS, and removable sunroof rounded out the feature set. Fender flares and special 16-inch wheels were available on the V6 and 4WD models. The Rodeo could also be optioned with a rear-mounted spare tire and its own 16-inch wheels on higher trim packages.
A new 2.2-liter X22SE engine built by Holden in Australia served as the base engine. Isuzu also offered the 205hp 6VD1 V6 that produced 214lbft of torque at 3000 rpm. Fuel consumption is an estimated 22mpgus highway. From a technical perspective, the Rodeo and Amigo were built with a rigid frame that has eight crossmembers. Front suspension has independent lower and upper arms, with a solid rear axle. The Rodeo and Amigo 4WD models came with a modified Dana 44 rear axle and push-button four-wheel drive. They also had a traditional floor mounted lever for switching from high- to low-range. Underneath, both vehicles came with protective skid plates as a standard feature.
The North American Isuzu Amigo and Isuzu Rodeo were built at the Subaru Isuzu Automotive, Inc. assembly plant in Lafayette, Indiana.
In October 2010, the U.S. National Highway Traffic Safety Administration (NHTSA) recalled 1998–2002 Rodeos, 2002 Isuzu Axioms, and 1998–2002 Honda Passports due to corrosion of the vehicle's frame in the vicinity of the rear suspension.[7] Vehicles without corrosion in the affected area would be treated with an anti-corrosion compound. Vehicles with more severe corrosion would have a reinforcement bracket installed. In some cases, corrosion was so severe that repairs could not be made, resulting in Isuzu and Honda purchasing vehicles from the owners. The final MU rolled of the assembly line on June 5, 2004.
After General Motors took full control over the IBC Vehicles factory in 1998, the Frontera production line was planned to be transferred to General Motors' Vauxhall plant in Ellesmere Port. However, with the closure of the Vauxhall Luton plant the decision to move was reversed. In 1998 the new model series was introduced with a choice of 2.2- petrol, 2.2-liter diesel (X22DTH) and 3.2-liter V6 petrol engines. Further modifications were carried out on the diesel engine post-2001, with the final version to be fitted in the marque being the 2.2-liter (Y22) version. This model met the Euro 3 Emissions standard.
The Frontera was discontinued from production at IBC Luton in 2004 (the final models in the UK were produced in Olympus trim). In Australia and New Zealand, the Holden Frontera was replaced by a Holden badged version of the Chevrolet Captiva model range, while in Europe it was replaced by the Opel Antara, that was also available as a Vauxhall.[8]
