Since we have a North American car in front of us, it is easy to guess that the car is traditionally equipped only with gasoline engines that have quite decent performance. The base version is an atmospheric hybrid 2.4-liter 4-cylinder 16-valve 182-horsepower power plant (233 Nm). The maximum speed is 227 kilometers per hour.
