At the core is Nissan's new 1.6-liter DIG (Direct Injection Gasoline) engine. a turbocharger combines with direct injection to wring 188 horsepower and 177 pound-feet of torque out of the little four-cylinder. As a result, the Juke can churn from 0 to 60 mph in about seven seconds. It can also get 27/32 mpg. Nissan's continuously variable transmission contributes to that efficiency by using a beltand-pulley system to access a continuous band of gear ratios so that the engine can run at the most efficient speed at all times. Optional all-wheel drive comes with a torque-vectoring system like those usually found on pricey sports cars. Sensors measure wheel speed, steering angle, yaw rate and gear position, and a central computer independently adjusts the amount of torque applied to each rear wheel, keeping the car stable during quick turns and highway merges and on slick uphills.
