1985 Jeep Comanche Bonneville Salt Flats Pickup
Based on the Cherokee-based Jeep MJ platform and unusual unit-body construction
with a variety of powertrain options, the advanced Jeep Comanche two-door pickup
truck was produced between 1986 and 1992. Despite its relatively brief production
cycle, the Comanche was remarkably successful, drawing market share from the “Big
Three” during its run. Chrysler’s buyout of AMC in the late 1980s was the cause of
the popular Comanche’s demise, given the auto giant’s own competing product, the
Dakota intermediate truck.

In addition to two and four-wheel drive variants, the Comanche was also available
with a powerful 4.0-liter inline six-cylinder engine, with strong bottom-end torque
and 173 hp on top when introduced in 1986 as an option beginning with the 1987
model year. In factory-stock trim, the Comanche was capable of startling
performance, with acceleration from rest to 60 mph in under 10 seconds, en route to
16.9-second quarter-mile times.

To introduce the new 4.0-liter engine and demonstrate its potential, a Comanche was
specially prepared in late 1986 with a modified engine for a series of sanctioned
speed runs at the legendary Bonneville Salt Flats in Utah. There, the Comanche set
four World Records, two National Open Records and seven National Truck
Records, achieving speeds in excess of 140 mph in the process!

These remarkable achievements were achieved by American Motors, one of the most
innovative automotive marques in America, which actually had a very successful
history in speed competition and racing to improve its production automobiles and
reap the press potential of its efforts. Other notable AMC successes included wins
at the Nurburgring 1,000 km endurance race in 1979 and Craig Breedlove’s 1968
assault on Bonneville in the famed AMX
