Cadillac Escalade Hybrid
The 2010 Cadillac Escalade Hybrid is the world’s first fuel-saving hybrid applied to a large luxury SUV. It achieves an EPA-rated 20 miles per gallon in the city, a 50-percent fuel economy improvement over the non-hybrid model. The Escalade Hybrid models are powered by GM’s innovative, fuel-saving 2-Mode hybrid system and offer the same dramatic design, luxury and full-size capability that have made the Escalade an icon.
For 2010, the Cadillac Escalade lineup also includes the Escalade Platinum Hybrid. It is the most technically advanced large luxury SUV yet, blending the exclusive features of the Escalade Platinum model with the fuel-saving powertrain of the Escalade Hybrid. Escalade Hybrid and Escalade Platinum Hybrid are available in 2WD and 4WD configurations.
GM’s patented two-mode hybrid system consists of an advanced, electrically variable transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS). These systems work in concert with the standard 6.0L V-8 Gen IV gasoline engine with Active Fuel Management (AFM) and late-intake valve closing (LIVC) technology.
The key to the 2010 Cadillac Escalade’s two-mode hybrid system is that the hybrid system itself generates the electric power used to propel the vehicle. When the brakes are applied or the vehicle is coasting, the electric motors within the hybrid system create electricity that is stored in the 300-volt battery. This stored energy is used to move the vehicle and the regenerative braking cycle is renewed.
Providing power to the hybrid’s electrically variable transmission’s (EVT) two electric motors is a 300-volt nickel-metal hydride Energy Storage System (ESS). This battery pack is under the second-row seat, where it takes up virtually no additional space and does not interfere with second- or third-row ingress/egress.
