Mitsubishi's Endeavor SUV undergoes some notable trim and features adjustments for the 2006 model year. The mid-level XLS trim has been dropped, reducing the total number of Endeavor variants to four. ABS has been added to the base LS standard features list, and all front-wheel drive models now come with traction control. The Limited loses leather upholstery and heated seats, but both are still available as options. These changes are part of a mid-cycle update, which includes some interior and exterior design alterations.
The Endeavor lineup is available with LS and Limited styles, and both can be had with either front or all-wheel drive. Convenience items like air conditioning, full power accessories, keyless entry, and CD player are standard across the board. All Endeavors also get 17-inch alloy wheels, tow preparation and a full size spare. The Limited is set apart by a more powerful stereo, a power driver seat and automatic climate control.
All Endeavors are powered by a 3.8 liter V-6, mated to a four-speed automatic transmission. This engine delivers 225 horsepower and 250 pound-feet of torque. The Endeavor will tow 3500 pounds, and fuel economy is estimated at 17/23 mpg.
The Endeavor is set apart from mid-size crossover competitors by its unique styling, and this has been a strong selling point for consumers. Reviewers report that the Endeavor offers a fine blend of car and SUV elements, adding the Endeavor combines a car-like ride, 4x4 abilities and adequate cargo space (75 cubic feet) in one attractive package.
The interior design is also rather bold, with metallic trim and blue backlighting. A closer examination reveals some lower grade materials, but the Endeavor's cabin is definitely distinctive. This SUV does not offer third row seating or an optional navigation system.
