The Jeep Comanche (designated MJ) is a pickup truck variant of the Cherokee compact SUV (1984–2001)[3] manufactured and marketed by Jeep for model years 1986-1992 in rear bicycle (RWD) and four-wheel bulldoze (4WD) models likewise every bit 2 cargo bed lengths: six-foot (1.83 metres) and seven-foot (two.xiii metres).[4]
Introduction [edit]
During the mid-1980s, according to AMC chairman W. Paul Tippett Jr. "People are finding trucks a reasonable and sophisticated alternative to cars."[five] To satisfy the demand and to compete with Japanese competitors, both AMC and Chrysler were preparing meaty pickups for the 1986 and 1987 model years (respectively).[5] Besides at this fourth dimension the financial health of AMC was poor and the automaker was in need of cash as it was preparing a new line of midsize sedans (the Eagle Premier) scheduled to be produced at a mill being built in Canada (Brampton Assembly), only the best thing the visitor had going for information technology was its popular line of Jeeps and introducing a compact Jeep pickup truck in the fall of 1985 was expected to aid.[half dozen]
The Jeep Comanche was introduced in mid-Baronial 1985, at a lavish event staged at the ballroom of the MGM Grand Hotel and Casino (currently Bally's Las Vegas) for AMC'south over one,500 North American dealers.[seven] American Motors included Chinese officials as office of the negotiations establishing Beijing Jeep (now Beijing Benz). The goal was to produce and sell Comanches in Red china through this joint venture.[seven]
The new trucks were unveiled past Jose Dedeurwaerder, an engineer and international business executive with 23 years of feel with Renault, who had just been appointed as AMC's new president.[8] The base of operations price of the 2-bike drive model was $vii,049 (adjusted but for aggrandizement equal to U.s.a.$16,962 in 2020 dollars[9]), making it the everyman priced Jeep model for the 1986 model year.[10]
Design [edit]
American Motors' Jeep designers based the Comanche MJ body, styling, engineering, and drivetrain on the XJ Cherokee, which had been introduced for the 1984 model year.[3] The Comanche had a somewhat more than conventional torso-on-frame design behind the cab and a removable cargo box, simply retained the unibody construction of the Cherokee in the front half of the vehicle. In the United States where the Comanche and Dodge Rampage were sold they are both considered pickup trucks. Past contrast, in other markets the Volkswagen Rabbit Pickup was called the Volkswagen Caddy and considered a coupe utility, not a truck considering the cargo bed is an integral role of the trunk structure and non removable. However this is not the legal definition of truck in the United States where the Comanche, Rampage and Rabbit were all sold.
Two cargo bed lengths were used; i for the vii-pes long-bed model, which appeared starting time in 1986, and a second, shorter version for the vi-foot cargo bed, which debuted for the 1987 model year. Unlike other pickups of the time that used C-channel frames, the Comanche'due south frame design (chosen a "Uniframe" by Jeep) under the cargo bed was fully boxed, with a large X structure centered over the rear axle. For force, the rail were over eight inches deep (peak to bottom), much deeper than conventional midsize truck frames (1983 Jeep J-10 total-size truck frame is 6.75 inches at the deepest bespeak). This structure was pioneered by AMC for the 1971 "Cowboy" compact pickup prototype.[eleven]
From 1986 to 1987, the Jeep Comanche grille had 10 slots in a similar configuration to the 1984-1987 Cherokee XJ, while from 1988 to 1992, this configuration changed to viii slots to match with the SUV.[12] A new "4x4" badge, like to those institute on the Cherokee and Wagoneer models, was affixed to the upper rear of the cargo box on all the four-wheel bulldoze models.[1]
After the Chrysler buyout of American Motors for $1.5 billion on March nine, 1987, designed to capture "the highly profitable Jeep vehicles ... and one,400 boosted dealers",[13] the Jeep Comanche, like the similar Cherokee, received merely pocket-sized changes. These were primarily to meliorate reliability and parts interchangeability with other Chrysler-built vehicles.
Suspension [edit]

The Comanche used the XJ Cherokee'southward "Quadralink" front suspension, with roll springs and upper/lower control arms on a solid axle. It was argued that the coil springs allowed for greater ride condolement and axle articulation during off-road excursions. A track bar (Panhard rod) is used to keep the axle centered under the truck. Modified versions of this same basic pause system were later used on the 1993-2004 Grand Cherokee, 1997 and newer TJ Wranglers and 1994 and newer Dodge Rams.
For the rear suspension, the truck used leaf springs that are considerably longer than the Cherokee'southward, which give Comanches good load-conveying capacity without creating a hard ride. The standard rear axle was the aforementioned Dana 35 used in the Cherokee, except that the Comanche mounted the leaf springs underneath the axle, as practice well-nigh other trucks, and the Cherokee mounted them on top of the axle. At that place was also a heavy duty Metric Ton package for the long-bed models. The package included heavier-duty foliage springs and wheels, larger tires, and upgraded the rear axle to a Dana 44, which increased the stock payload (cargo) capacity from 1,400 to ii,205 pounds (635 to 1,000 kg), well above that of any other mid-size truck. The Metric Ton Comanche's payload rating was higher than that of many total-size pickups.
Drivetrain [edit]
The inaugural 1986 model yr Comanches could be equipped with one of three engines: AMC's two.5 Fifty iv-cylinder as standard, with General Motors' 2.viii L V6 or Renault's 2.ane Fifty I4 turbo diesel available equally options.[3] In base trim the four-cylinder engine was backed by a four-speed manual transmission, with either a 5-speed manual or iii-speed TorqueFlite A904 automatic built by Chrysler equally an pick. The V6 engine was available with either the five-speed transmission or the automatic, while the turbodiesel was just available with the 5-speed.
The V6 was the same engine used in the competing Chevrolet S-10, and equipped with a ii-barrel Rochester carburetor instead of the four-cylinder's electronic throttle-body fuel injection organisation the optional half dozen-cylinder was slightly less powerful than the standard iv. The V6 thus offered little performance advantage over the base of operations engine while penalizing the owner with poorer fuel economic system. In the truck's 2d year on the market the V6 was replaced by AMC'southward new fuel-injected 4.0 L straight-six that developed 173 hp (129 kW; 175 PS) and 220 lb⋅ft (298 N⋅one thousand): 50% more ability and 47% more torque than the previous V6.[14] The new six-cylinder was also more fuel-efficient. The performance of the base 2.5 L engine was also improved with a new air intake, raising peak output to 121 hp and 141 lb⋅ft. The slow-selling turbodiesel pick was dropped during the model year.
Concurrent with introduction of the new direct-6 a new four-speed automatic congenital by Aisin-Warner replaced the one-time Chrysler three-speed. The thirty-40LE featured electronic controls with a switch on the dashboard allowing the commuter to choose between ii performance modes: "Power", in which the transmission downshifts more speedily and upshifts at higher rpm during hard acceleration, and "Comfort", in which the upshifts are made at lower engine speeds to conserve fuel and reduce engine noise and vibration.[15]
In 1988 output of the iv.0 L engine was improved slightly to 177 hp and 224 lb⋅ft.
Chrysler purchased AMC in 1987, and past the 1991 model year adapted their own engine control electronics to replace the original Renix systems used with the ii.5 L and iv.0 Fifty engines. Ability and torque in both engines improved as a result, with the four-cylinder having an additional 9 hp and 8 lb⋅ft and the six-cylinder improving by 1 lb⋅ft and 13 hp. The iv.0 L was badged "High Output" thereafter. As a result of the ability improvements the Aisin-Warner automatic transmission's output shaft was inverse from 21 splines to 23, and the "Power-Comfort" switch was deleted. The four-cylinder was no longer available with the automated in 1991 and 1992.
During the product life of the Comanche vi different transmissions were offered, manufactured by Aisin, Chrysler, and Peugeot. Chrysler provided the same TorqueFlite 904 iii-speed automatic in 1986 models. In addition to the aforementioned thirty-40LE four-speed automated Aisin besides provided the AX-4 (four-speed), AX-5 and AX-fifteen (five-speed overdrive) manual transmissions. The AX-15 was phased in midway through the 1989 model year to replace the Peugeot BA10/v 5-speed that had been used backside the iv.0 Fifty engine from its introduction in 1987.
Comanches were available in either two or four-cycle-drive, with solid axles front and rear (2-bicycle-drive Comanches used a simple beam beam with otherwise the same front interruption as four-wheel-bulldoze models). Transfer cases were built by New Procedure Gear, and the Comanche was available with either part-time "Control-Trac" or total-fourth dimension "Selec-Trac" systems. In 1986 Command-Trac transfer cases were model NP207 and Selec-Trac were NP228, both with a 2.61:1 depression gear ratios. In 1987 the NP207 was replaced with the NP231 and NP228 was replaced with the NP242, both with 2.72:1 low gears. These remained the same through the rest of the Comanche'due south production.

Phaseout and aborted proper name revival [edit]
The decision to phase out the Jeep Comanche "came from a combination of two factors— low sales and Chrysler's attempts to make the Jeep brand fit into the Chrysler hierarchy of Plymouth, Dodge, and Chrysler models" with Jeep housing SUVs and Contrivance making trucks.[17]
As sales dropped, the Comanche was planned for discontinuation. In 1990, the National Council of Jeep-Eagle dealers asked Chrysler to discontinue the Comanche, and allow them to sell a version of the Dodge Dakota pickup.[18]
The company decided to cease production of the Comanche on June 12, 1992, subsequently only a few 1000 more trucks rolled off the Toledo, Ohio, assembly line.[nineteen] A full of 190,446 Comanches were made during its production run.[20]
Following the discontinuation of the Comanche, the Dodge Ramcharger would be dropped outside of Mexico shortly afterwards equally role of Chrysler'due south plans to have Dodge sell pickup trucks and Jeep sell SUVs. Despite that, Dodge would after re-enter the SUV field with the Dodge Durango in 1998 at the height of the initial SUV boom and at ane signal would offer three SUVs or crossovers (Durango, Journeying and Nitro, the latter beingness a rebadged version of the Jeep Liberty (KK)) while Jeep didn't offering whatsoever pickup trucks. Dodge itself would stop offering pickup trucks in 2011 when the Ram Trucks make was spun-off from Contrivance, taking the Contrivance Ram and Dakota with it.
Jeep re-entered the pickup truck market in early 2019 with the Wrangler-based Jeep Gladiator. Jeep actually considered reviving the Comanche name aslope Gladiator and most usually Scrambler, as well as simply using a new name, earlier deciding on Gladiator, feeling it fits that truck the best; sensitivity to the Native Americans (specifically the Comanche tribe) and much less make recognition compared to Jeep's decades-long use of "Cherokee" for the Jeep Cherokee and Grand Cherokee also likely played factors.[21] The new Gladiator will serve equally a 27-twelvemonth subsequently replacement for the Comanche.
