Standard 2.7L four-cylinder delivers 25 mpg but falls short on performance.

Optional 4.0L V6 adds 77 more hp, bumps towing to 6,500 lbs.

At 159 hp, the 2.7L four cylinder takes 9.1 seconds to go from 0 to 60.

Thankfully, problems are few , making the 2.7L a reliable option.

The 4.0L V6 is more pleasant to drive with its 236 hp.

Towing capacity also spikes to 6,500 lbs.

But head gasket failure has been reported on high-mile units.

The 2.7L is wimpy, but it gets 25 mpg highway.

The 4.0L V6 can be pushed the limit with few issues.

But watch out for a blown head gasket near 250k miles.
