the left headlamp) and the sideview mirrors were repositioned (leading to the return of vent windows as an option). For 1982, the LTD saw the addition of the Ford Blue Oval emblem on the grille and trunklid (replacing "FORD" badging). To aid in tracking fuel consumption, a trip computer was added as an option. While standard, the 4.2L engine was offered for the final time. The 5.8-liter engine was dropped from retail sale, becoming exclusive to police car use; alongside the Motorcraft 7200VV two-barrel variable venturi carburetor; a conventional carburetor was available with the police option high-output 351. Introduced as an option with the 5.0L engine for 1980, the AOD overdrive transmission became paired with all three engines. Production Figures: Fourth generation (1983–1986) From 1981 to 1983, Ford underwent a major revision of its full-size and mid-size product lines, involving all three of its divisions. For the 1983 model year, the LTD and LTD Crown Victoria split into distinct product lines. The latter became the full-size Ford sedan range (alongside the LTD Country Squire), with the LTD nameplate effectively replacing the Ford Granada (and Mercury Monarch) in a mid-cycle model revision. In line with Ford, the Mercury Marquis and Grand Marquis were also split into distinct product lines; replacing the Cougar (sedan and wagon), the Marquis became the counterpart of the repackaged LTD. The more aerodynamic design had a slanted nose and a large greenhouse; drag resistance was down to . Shedding nearly 13 inches of length, 9 inches of wheelbase, 7 inches of width, and over 600 pounds of curb weight (dependent on powertrain), the 1983 LTD underwent nearly the same reduction in size as its 1979 predecessor, although this downsizing came as the result of re-marketing a stronger-selling nameplate for a slow-selling model line. Ultimately, the LTD became the third-best selling automobile in the US for 1983 and 1984. The chassis was also overhauled and now featured nitrogen-charged shocks and struts and larger wheels. The buyer received a standard split-bench front seats, while fabric coverings replaced much of the vinyl from the Granada. Ford recycled the use of the 1980–1982 Thunderbird instrument panel for the new LTD including the optional digital instrumentation. Ford's "Tripminder" trip computer was a novel option, allowing the driver to monitor fuel consumption, average speed, and various other functions.
