Infinity is a manufacturer that produces mostly sporty cars, but for the 2014 Infiniti Q50 Hybrid what they have successfully done has been keeping most of the sporty spirit of the brand while enhancing the fuel mileage by a lot. This car comes with a 354 horsepower from a 3.5-liter V-6 engine that works together with an electric motor to make this an extremely potent vehicle. The only gearbox available for the Infiniti Q50 Hybrid is a seven-speed automatic transmission.
