2008 Mazda Tribute Hybrid Electric Vehicle Features
| A special 2.3-liter four-cylinder gasoline engine features Atkinson-cycle combustion for improved efficiency and produces 133 horsepower at 6,000 rpm. A 70-kWatt (equivalent to 94 horsepower) electric traction motor provides an added boost to the drive wheels when maximum acceleration is desired. A generator-motor recharges the batteries, starts the engine and helps regulate how the two propulsion channels blend together in the transaxle. A special electronically controlled, continuously variable transmission (eCVT) harnesses internal combustion and electric power sources to drive the vehicle. A 330-volt nickel-metal-hydride battery pack located and sealed at the rear load floor stores electrical energy. An electronic vehicle system controller manages charging, drive assist and engine-starting functions. This device shuts the engine down during coasting and at stoplights to save fuel. It also converts the traction motor into a generator during braking to help recharge the batteries. |
