Base Coopers run with turbocharged three-cylinder engines; The S version gets a 2.0-liter turbo four-cylinder; six-speed manual and automatic transmissions for both.
Most people love Minis. Their tiny, yet earnest appearance makes us smile and perhaps wish they were big enough for us to bring the gang along for the ride. To that, BMW’s Oxford, England-based designers say, “challenge accepted”. For 2015 they’ve brought out a new four-door model called, appropriately enough, the Hardtop 4 Door. While they were at it, they renamed the two-door hardtop the…you guessed it. To create the 4 Door, more than half a foot was added to the 2 Door’s length and the wheelbase was enlarged by about three inches, with half going to increasing rear legroom. The extended roof also provides an extra half-inch of headroom. In back there’s a bit more stowage space with the seats in place, but the payoff comes when you drop the split-folding 60:40 rear seat to discover plenty of volume for bulky gear. Both two- and four-door Minis use engines that are built off of a modular block, where each cylinder is a half-liter in size. Thus the turbocharged three-cylinder base Cooper engine displaces 1.5 liters and produces 134 horsepower and 169 pound-feet of torque (up from 121/114). Similarly, the turbocharged 2.0-liter four-cylinder engine in the Cooper S makes 189 horsepower and 221 pound-feet of torque (previously 181/192). Each of the so-called “TwinPower Turbo” engines uses an all-new six-speed manual transmission. Minis fitted with the optional six-speed automatic include fuel-saving stop-start technology and, for models equipped with the navigation system, will adapt to your specific route (e.g. will automatically downshift when negotiating a sharp turn or when approaching an intersection). Note that the two-door Mini Convertible lineup soldiers on for now with turbocharged and non-turbocharged 1.6-liter four-cylinder engines.
