Comanche Engine Upgrade in 1987 Model

The 1987 Comanche (as well as Cherokee and Wagoneer) will receive a power boost with electronically fuel-injected 4.0 L, 6 cylinder engine.

The I-6 specifications are as follows:
0 to 60 in less than 10 seconds
Peak 173 hp @ 4,500 rpm
220 lb ft of torque @ 2,500 rpm

This is a 50 percent gain in horsepower and 47 percent gain in torque over the V-6 engine offered in 1986.

The I-4 will also receive an upgrade due to using the same, larger air cleaner as the I-6.
Specifications are as follows:
121 hp @ 5,000 rpm
141 lb ft of torque @ 3,500 rpm

Also introduced in 1987 are the following:
New wide-ratio, 4 speed automatic transmission
New NP 242 transfer case
