Making its debut for 2008, the Mazda Tribute Hybrid Electric Vehicle, or HEV, typically operates solely on electric power at speeds of up to 25 mph, when its gas engine kicks in to provide additional power. The hybrid configuration results in fuel economy numbers of up to 34 mpg in the city, as well as lower emissions than a standard gas-powered SUV. The Tribute Hybrid SUV comes in front-wheel-drive or four-wheel-drive trims and seats up to five passengers.
The Tribute Hybrid's powerplant consists of a 153-hp, 2.5-liter, four-cylinder Atkinson-cycle gas engine and a permanent-magnet AC synchronous electric motor. Together, the gas engine and electric motor generate 177 hp and 135 lb-ft of torque. They link to an electronically controlled continuously variable transmission (eCVT). Another component of the powerplant, the 330-volt nickel-metal-hydride battery pack, resides beneath the rear cargo floor. The Tribute Hybrid's front-wheel-drive trim posts fuel economy numbers of 34/31 city/highway miles, while the four-wheel-drive trim manages a still-respectable 29/27.
For quick starts or when the vehicle is heavily loaded, the gas engine engages off the mark, with the electric motor providing additional torque. When decelerating, the gas engine shifts into generator mode, charging the Tribute Hybrid's battery. The gas engine shuts down at cruising speeds or when the vehicle stops at traffic lights to help conserve fuel.
The hybrid engine provides good overall performance, according to reviewers and drivers, although the Tribute Hybrid SUV can take a little longer to accelerate than typical gas-powered SUVs, some drivers note. However, the hybrid powerplant seamlessly transitions from electric power only to the electric/gas combination to gas-engine-generator mode. Most drivers won't notice as the transitions occur, other than by viewing hybrid-related gauges on the instrument panel.
The Tribute Hybrid benefits from a design update applied to the entire Tribute line for 2008. Exterior changes, including an updated grille, give the Tribute a more contemporary look, while interior improvements result in a quieter, more comfortable cabin.
The Tribute Hybrid comes in Touring and Grand Touring trims for 2008, with such standard features as a leather-wrapped steering wheel, remote keyless entry, Sirius satellite radio, and foglights. The Grand Touring trim adds a power moonroof, leather-trimmed seats, and six-way power-adjustable heated front seats, among other features. Both trims ride on 16-inch wheels with low-resistance tires and include such safety features as stability control, traction control, and a full range of airbags.
