The XL 4WD represents a step up from the XL, including a standard 4.6-liter, 248-hp V8 engine and four-speed automatic transmission. But while the engine may have a few more horses, this trim comes up even shorter than the XL on features. Options include air-conditioning and a CD player, but power locks are not offered. Fortunately, the XL 4WD does have standard ABS brakes. If you feel the need for some extra power, you can upgrade to a 5.4-liter, 300-hp V8. But keep in mind that despite the stronger standard engine, the XL 4WD tows only 8,200 lbs, compared to the XL's 8,500.
