"The 2009 Chevrolet Tahoe Hybrid is a 4-door, 8-passenger sport-utility, available in two trims, the 09 Chevy Tahoe 1HY 2WD and the 09 Chevy Tahoe 1HY 4WD." |
"The 2008 Tahoe Hybrid is a 4-door, 9-passenger sport-utility, available in two trims, the 1HY 2WD and the 1HY 4WD. Upon introduction, the 1HY 2WD is equipped with a standard 6.0-liter, V8, 332-horsepower, hybrid engine that achieves 21-mpg in the city and 22-mpg on the highway." |
"Cars.com's Joe Wiesenfelder takes you through the 2008 Chevy Tahoe Hybrid." |
"Equipping a large SUV with hybrid technology may seem counterintuitive; certainly a smaller car-based hybrid would offer better fuel-economy, but the reality is that many people need to haul large amounts of cargo or carry more than five passengers, and they'd like to save the planet, too. The Chevrolet Tahoe hybrid lets buyers retain all the functionality of an SUV while using substantially less fuel. " |

The key to Tahoe Hybrid's efficiency is the two-mode hybrid propulsion system which helps Tahoe Hybrid 2WD offer the same city fuel efficiency as a standard 4-cylinder Toyota Camry.(1) Mode 1 In the first mode, at low speed and light load, the vehicle can operate in three ways: electric power, engine power, or in any combination of electric and engine power. When operating with electric power, it provides all the efficiency of a full hybrid system. Leaving the engine shut off for extended periods of time and moving under electric power is key to reducing fuel consumption in heavy stop-and-go traffic. But when you need the extra muscle of Tahoe's Vortec V8, it is there to seamlessly kick in and deliver the power you expect. Mode 2 The second mode is used primarily at highway speeds to optimize fuel economy and help Tahoe Hybrid offer an astounding EPA estimated MPG 21 city, 22 highway for 2WD models, and 20 city, 20 highway for 4x4. It provides electric assist in addition to four-cylinder or full eight-cylinder power when conditions demand it, such as trailer towing and climbing steep grades. Put another way, you'll experience the benefit of low fuel consumption with plenty of horsepower, torque and utility. The second mode integrates sophisticated hardware, such as cam phasing and late-intake valve closure to allow for even more efficient engine operation. There's also Active Fuel Management, which smoothly shifts from eight cylinders to four and back, depending on how much power is needed. The addition of a second mode to the drive system improves efficiency and reduces the need for large electric motors, which are used in today's single-mode systems. Tahoe Hybrid employs two smaller motors that are lighter and efficiently packaged within the space of its automatic transmission. Shifts between the two modes are synchronous, which means no engine speed changes are necessary for the mode shift to occur. This results in very smooth acceleration. [Chevrolet.com] |
