Cadillac announced the world premiere of the Escalade Hybrid, the world's first fuel-saving hybrid applied to a large luxury SUV. Powered by an innovative, fuel-saving 2-Mode Hybrid system, Escalade Hybrid will deliver more than a 50-percent improvement in fuel economy in city driving - all while delivering the same distinctive style, segment-leading features and full-size capability that have made the Escalade an icon.

Acoustic details specific to the Hybrid model ensure it delivers the superior luxury that has been an Escalade hallmark since its inception. The details include:

A new exhaust system and resonator specially tuned for the 6.0L LIVC engine's Active Fuel Management operation. It ensures comfortable interior acoustics and a pleasant exhaust note during both V-4 and V-8 operation
An electrically driven, 300-volt air conditioning compressor reduces vibration and allows the HVAC system to cool the passenger compartment even when the gasoline engine is shut off. It includes the standard tri-zone climate system
An electrically driven, 42-volt variable-assist power steering reduces vibration and provides up to a 0.5-mpg fuel economy improvement by reducing parasitic losses common in belt-driven hydraulic systems
The Energy Storage System cooling system's internal fan is tuned to be quiet at low vehicle speeds, when the fan could more easily be heard by the occupants.

The Escalade's 2-Mode Hybrid system allows it to return exceptional fuel economy in both city and highway while delivering the capabilities of a true luxury SUV. In city driving, this advanced hybrid power system enables Escalade to launch and drive low speeds on electricity alone. As additional power is demanded, the system blends output from the battery and gas engine smoothly.

GM's patented 2-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. AFM enables the V-8 engine to seamlessly shut off half of its cylinders when less power is needed, such as during highway cruising. This new hybrid system not only enables the Escalade Hybrid to drive low speeds on electricity alone, it also allows the 6.0L V-8 engine to operate in its more economical four-cylinder mode for longer periods.

Escalade Hybrid is available in 2WD and 4WD configurations. It delivers up to 6,000 pounds (2,722 kg) of usable towing capacity on 2WD models and 5,700 pounds (2,565 kg) on 4WD models. All of Escalade's standard comfort and convenience features are included. This includes an eight-inch, touch-screen navigation system that displays performance readouts of the 2-Mode Hybrid system on the screen.

The key to Escalade's 2-Mode hybrid system is that the electric power used to propel the vehicle is generated by the hybrid system itself. 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.
