In the begining... In the beginning there was the Ford Courier, a small pickup manufactured my Mazda for Ford in the late '70s. Ford decided to produce their own truck that would be a small version of the larger F-Series and based on a similar (smaller) chassis. Ford raced to have the Ranger finished for the 1983 model year (released in 1982), to compete with Chevrolet's new S-10. Chevy was in the midst of producing a mini SUV based on the S-10, which they named the Blazer, and released shortly after the S-10. Ford did not want to be left in the dust, especially after seeing all the difficulties of other manufacturers of the era (such as Chrysler, and A.M.C., which both were on the verge of bankruptcy). So Ford set impossible deadlines for this new SUV to be debuted, in order to claim some of the market that the new Blazer was sure to devour...and that is where it all started.
The Rocky Road The first issues started in the design process when the engineers doubted the stability of such a narrow vehicle, but do to the tight schedule and budget this issue was ignored. In order to make the vehicle more stable, a new chassis would need to be designed, and this would be costly and defeat the purpose of designing a Ranger based SUV. By the end of t (Click Image for Larger Photo) The Little Engine That Could The Ranger first debuted with only the 2.0 and 2.3 Lima four cylinder engines in 2wd standard cab, and shortly after that the 2.8L V6, and then a rare diesel. Later in the '83 model run 4wd was added using a Dana 28 axle based on Ford's TTB (twin traction beam) suspension. Mated to the transmission was a Borg Warner 1350 transfer case. When the Bronco II arrived, Ford considered the added weight compared to the Ranger, and gave the Bronco II the 2.8L V6 with no other engine options. This is the same 2.8 that was originally designed in Cologne Ge
Getting With the Times During the mid 1980s, there were many transitions happening in the automotive world, especially with the introduction of computers and computer controlled carburetors. Technology was about to expand by leaps and bounds, especially as fuel injection became more popular. The old 2.8 was just about as fancied up as Ford was willing to go with a carbureted engine, so they decided the 2.8 needed to become fuel injected. In updating many things Ford overhauled the whole 2.8L ideology, and made a new 2.9L V6 whose basis was still somewhat of the 2.8. After Ford experimented with their version of throttle body injection (TBI) which Ford used the term Central Fuel Injection (CFI), Ford knew this was somewhere they didn't want to go again, so they went with the more reliable (and complex) Multi Point Fuel Injection (MPFI) which has one fuel injector per intake port (1 injector per cylinder). Finally Ford was ready to deposit the 2.9L into the Bronco II and Ranger for the 1986 model year. And a good engine it was, creating 140hp at the flywheel and 160 foot pounds of torque, while not sacrificing any fuel mileage, and helping to decrease emissions. A few changes were made such as losing the EGR and decreasing the throttle body from 58mm to 50mm for the 1988 model year. The California Emissions 1989 Bronco II received a newer style computer system in place of the old speed density. Speed density uses a MAP (manifold absolute pressure sensor) rather than a MAF (mass air flow sensor), the MAF system more accurately controls engine calculations. From Rugged to Soccer Mom The first year of the Bronco II was certainly the most basic in regards to luxury options. Sure there were options such as side vent windows, variable speed window wipers, and automatic transmission, but there were many things that lacked. Maybe an explanation of the
Special Editions There were a few special editions of the Bronco II. Most of these vehicles are very rare, and many were from aftermarket outfitters. However, the
Back to the Future Well, obviously the Bronco II was replaced by the Explorer, and 1990 was its last model year. The Explorer started where the Bronco II left off. It started with a similar Ranger Based Platform, and shared essentially the same front end. The Explorer started off as a 4 door model with a 2dr sport option. It offered the same transmissions, and axles as the previous years Bronco II, but replaced the 2.9L with Ford's 4.0L OHV V6. The Explorer kept to the Ranger based tradition until 1995 when it was overhauled with a major exterior restyling, and chassis modifications to allow the new addition of Ford's 5.0L V8, and that was the end of the line for any reminisce of the Bronco II.
