Letters F-O-R-D were removed from the hood and the blue oval was placed in the center of the grille and on the left side of the tailgate.

This 4bbl motor put out 210 HP at 4000 RPM vs the old 351 CID V-8 which was 156 HP @ 4000 RPM It was basically a 351W with a "Mustang 5.0 HO" treatment: higher compression and a Holley 4 barrel carb. 4.10/4.11 gear ratios were also available as an option, but not with limited slip.
1985: had some engine changes. the I-6 now had a serpentine belt. The big change was the 302, multi-port EFI. HP for the 302 was now 190 and torque was up to 285. This motor was avail in California only with a manual trans. The 351 and 351 HO motors were optional. The Eddie Bauer trim package debuts, brought to the full-sized Bronco due to fabulous success with the Bronco II. Also, midside body moulding changed from chrome to black plastic.
1987 featured another major body restyling for the Bronco. The new aero look was in and the Bronco followed suit. The transfer case was replaced by a Borg-Warner 1356 with a 2.69 low range. 4.10 gearing was optional. Touch drive was first offered this year. The 351 HO V-8 was still optional and the 300 CID I-6 recieved Multiport fuel injection (MPI). Rear anitlock brakes were made standard.

Torque increased form 295@2600-315@2800. The entire engine line was now fuel injected and also serpentine belt equipped. Transfer case skid plate was now standard.
1991: was the 25th anniversary of the Bronco and no long-term changes were made. However, Ford did make a Silver Anniversary Edition of the Bronco available to commemorate the occasion. This limmited edition Bronco was offered only in Currant Red with gray leather interior. This was the first factory offering of leather seating on the Bronco and was only available on the Silver Anniversary Edition. The Currant Red paint was also exclusive to this edition. The E4OD became the stock automatic transmission.
1992: realized the last major body restyling in the Bronco's lifespan. This change offered much more swept front sheetmetal that curved in at the fenders. Power window/lock controls moved up the doorpanel towards the top to make them more accessible. Power mirrors are now offered for the first time. Rear passengers are restrained via integral shoulder/seat belts. Colored stripe in the tailgate bezel is changed from red to black. Leather seating is now an option on XLT and Eddie Bauer trim levels. Ford also offered the NITE option package, for only this year. The package was all black, including the top. Special graphics were applied.
1994: brought us a drivers side airbag, side door beams and CFC free A/C. Fake rivets disappear from the optional aluminum wheels. Center hub bezel on steel and aluminum wheels changed from red to black. Californai V8's went from Speed density to MAF.
1995: Ford reprogrammed the E4OD automatic trannsmission for smoother shifts. The 351 CID V-8 went to sequential MPI with mass air in california. Lower body side trim color for Eddie Bauer package is changed from the traditional tan to bronze.
1996: last year for the Bronco, debutted OBD-II electronics. Side mirrors with integral signal lights were offered for the first time. 302 CID and 351 CID HO MPI motors were still offered. The axles were still the 8.8 inch out back offered in 1983 and Dana 44 TTB front that started in 1980. All V8's got MAF as well.
1997: Sadly, the Bronco name is laid to rest in favor of the new "Expedition" model that is based on the new F150. Pent up demand has these things currently flying out the door as fast as the dealers can unload them off the trucks (at least in Austin - they are already EVERYWHERE). Only offered with 4-doors, the vehicle is aimed squarely at the Chevy Tahoe and Suburban. Dual air bags and 4 wheel ABS are standard. Venerable 302 and 351 Windsor motors are gone in favor of 4.6L and 5.4L variants of the Ford "modular" OHC motors. Front suspension is now double A-arm (a'la Chevy, unfortunately) and 4x4 models are sprung by torsion bars up front. First Ford 2WD offering in this class. I lament the loss of this proud marque but I suppose it was nice of Ford to set it up so that there will NEVER be a 2WD Bronco.
