Budget Rent A Car has been adding fuel-efficient 2014 model-year vehicles to its rental fleet that are now available to its rental customers in the U.S., according to the company.

The Budget 2014 lineup features the MINI Cooper Clubman and the MINI Cooper Countryman. The MINI Cooper Clubman seats four and is rated at 35 miles per gallon highway by the U.S. Environmental Protection Agency.

In addition, the vehicle features a side club door and split rear door that, according to MINI, "helps move awkward objects (and passengers) with as little fuss and as much fun as possible." Meanwhile, the MINI Cooper Countryman features four doors, seating for five and a fuel efficiency rating of 35 miles per gallon (highway). Other noteworthy fuel-efficient cars in the Budget fleet include the Ford Fusion, Hyundai Accent, Kia Rio, Toyota Prius, and Volkswagen Beetle.

Budget's model-year 2014 vehicles also feature entertainment systems available in SUVs and most minivans. Rear DVD systems are included in the Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon. Each vehicle seats seven people and boasts a 5.3-liter V-8 engine, rear-view camera and rear parking assist. Some are also equipped with heated second-row seats and power-remote lift gates.

Rear DVD systems are also featured in 65% of new Chrysler minivans in the Budget fleet, specifically the Chrysler Town & Country and the Dodge Grand Caravan.

Travelers looking for adventure can enjoy the 2014 Ford Mustang Convertible also available in the Budget fleet. The rear-wheel-drive convertible features a 305-horsepower V6 engine and seating for four. Other noteworthy vehicles in the Budget fleet include the Jeep Wrangler (available in Hawaii), the Ford F-150 SuperCrew pickup truck and Ford Econoline E-350 12-passenger van.
