After 10 years of sales in the United States, the MINI brand has evolved considerably past the single three-door hatchback. For 2011, the MINI vehicle line consists of four specific models including an all-new crossover. Featuring four passenger doors and available all-wheel drive, the MINI Countryman is quickly distinguished from the existing vehicles in the brand's product lineup. Sporting a new level of practicality for MINI, the 2011 Countryman's interior is highly configurable. Engine power for the entire MINI lineup has been improved for 2011 with the base 1.6-liter four-cylinder powerplant now generating 121 horsepower and the turbocharged S models producing 181 horsepower. 2011 S models are also presented with an overboost function that allows the delivery of a temporary increase of torque. MINI Cooper models are also presented with revised exterior styling and standard satellite radio for 2011.
