The Isuzu Bighorn was an SUV, the 1981 Isuzu produced until 2002. The Bighorn was the first SUV in the SUV style made in Japan, and role model for the later published domestic competitors Mitsubishi Pajero and Toyota Hilux Surf. The Bighorn was still made in truck design with ladder frame and accordingly the suspension was not very comfortable. Therefore, the sales in the domestic market was initially slow, but increased with each new Competitors increasingly. The Isuzu Bighorn was offered in the domestic market and New Zealand. On the export side, he was mostly Isuzu trooper, but was also marketed by various manufacturers by badge engineering as a separate model, described in the various generations.
In September 1981, the model first appeared on the domestic market as Isuzu Big Horn Rodeo. The background of the name was published in 1980 Isuzu Faster Rodeo, the first SUV from Isuzu four wheel drive. At that time, Isuzu planned to designate all 4WD models with the suffix Rodeo. Therefore, some car models in the home market of Isuzu also contributed this designation, with the increasing export of Isuzu models and the marketing by GM abroad was this practice However reinstated.
The Big Horn Rodeo was only 3-door SUV or 3-door panel van available with short or long wheelbase. Alternatively, there was the SUV soft top or hard top roofs. When the soft top 5 seats were 4 seats, the hardtop available. Was powered by a 2.2 L diesel engine with (45kW/62PS) and a 2.0 L petrol engine with 65kW/88PS consisting of the Isuzu 117 Coupe came from, combined with four-speed manual transmission or optional 4-speed automatic transmission from Aisin-Warner. The all-wheel drive had manual freewheel hubs. A power steering were standard, depending on market. Front disc brakes and rear drum brakes were used. Parallel to the launch in Japan Isuzu offered the model in New Zealand to. Holden marketed the model built by Isuzu as Holden Jackaroo. As Isuzu Trooper, the model was gradually introduced worldwide.
In particular, with the diesel engine, the vehicle was limited in performance, which limited the popularity with private customers. Then Isuzu responded in January 1984 with the installation of a turbocharger for the diesel engine, whereby the power to 54kW/73PS (In exports, he made some 55kW/75PS) increased. This engine received a 5-speed manual transmission, which is also optional stood for the other engines. At the same time the model was more variable rear seat backs, the could previously only folded as a whole, the 5-seater model. With these revisions Isuzu also changed the name of the model in Isuzu Bighorn.
As of June 1985, there was now also a five-door model with an extended wheelbase and the fuel tank grew from 50L to 83L. A 2.3 L petrol engine was added 81kW/110PS new, while the 4-speed manual transmission was no longer available.
In 1986 there were for the export model Trooper a 2.2 L diesel engine with a Garrett turbocharger and 64kW/87PS for the U.S. market. Due to the unconvincing performance of this engine was in 1987 taken out of the program.

The Irumusha special models were now also offered in the domestic market and in the other exporting countries such as the 2.6 L petrol engine. Now In its home market the Subaru Bighorn Subaru was offered by badge engineering. It was only with the 2.8 L turbo diesel variants. The Subaru Bighorn was built even after the end of the Isuzu Bighorn I to 1993 and sold, but received no successor.

It was a 3.2 liter V6 petrol engine with EFI injection system, which made 130kW/177PS. The 2.8 L direct injection diesel engine, which originally from an Isuzu truck came, was not installed because it did not meet the emission standards in many markets. Therefore, there was now a 3.1 L vortex chamber injection turbo diesel engine with charge air cooler with a capacity of 84kW/113PS. The engine power was transferred as previously via a five-speed manual transmission or a four-stage automatic transmission. Like its predecessor, it had selectable four-wheel drive and manual or automatic depending on the market freehub.
