fourth-generation LTD has a 105.6-inch wheelbase. In contrast to both the Granada and the full-size LTD, the fourth-generation LTD was sold as a four-door sedan and a five-door station wagon (no two-door versions were offered). Alongside the base-trim sedan and wagon (the only versions available for the first model year), the LTD Brougham trim made its return, along with a LTD Squire wood-trimmed wagon. For its 1983 launch, the LTD retained two engines from the Granada: a 2.3-litre Lima inline-four (not available as a wagon) and a 3.3-litre Falcon Six inline-six. Also inherited from the Granada was a 3.8-litre Essex V6 with , which replaced the inline-six entirely for 1984. For 1984, both engines gained central point fuel injection in the United States (the Canadian-market V6 remained carbureted until 1986). A rare option, seen only in 1982–1984, was an LPG (propane)-powered version of the four-cylinder engine; it was largely discontinued due to poor sales and lack of propane fueling infrastructure. The four-cylinder was a slow seller throughout; Ford kept offering it for the duration of production but in 1986 only 485 four-cylinder LTDs were sold, representing 0.7 percent of overall LTD/Squire sales for the year. For the first time since 1971, the LTD was offered with a manual transmission; a three-speed automatic was optional on the 2.3 and standard on the 3.3-litre engine. The larger 3.8 was only offered with the overdrive four-speed automatic. For the 1985 model year, the LTD underwent a minor model revision. Along with minor changes to the taillamps, the LTD received a new grille, distinguished by a centered Ford Blue Oval emblem. 1986 models are identifiable by the addition of a federally-mandated CHMSL (center brake lamp). LTD LX From the mid-1984 model year and throughout the 1985 model year, Ford offered a performance version of the LTD, marketed as the LTD LX. It came standard with a high-output 5.0 L CFI V8 engine, four-speed automatic transmission with overdrive, 600 lb-in front and 270 lb-in rear coil springs, front and rear sway bars, 10 inch front disc and 10 inch rear drum brakes, and a 3.27:1 rear gear ratio with a Traction-Lok differential. The LX was the only LTD of this generation to have a tachometer in the instrument cluster (1977–1979 LTD IIs had an optional tachometer). The center console and floor-mounted shifter re-appeared, having last been available in the full-size 1972 model year and mid-size
