ESCALADE HYBRID: CADILLAC PREMIERES THE FIRST HYBRID IN A LARGE LUXURY SUV |
|
Patented 2-Mode Hybrid technology The Escalades 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. GMs 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. The key to Escalades 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. The 2-Mode Hybrid system provides seamless, dependable power on demand in an efficient package. In fact, its electric motor is less than half the size of those in single-mode hybrid systems. This technology was developed and is still used in fleets of hybrid transit buses on the streets today in dozens of major North American cities. Scaled-down for use in full-size SUVs, the 2-Mode system delivers fuel savings where it is needed most in large vehicles with high levels of capability. It is a core part of GMs energy diversity efforts, which are centered on reducing dependence on petroleum, improving fuel economy, reducing emissions and minimizing the automobiles impact on the environment. Cadillacs smooth and quiet power 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 engines 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 systems internal fan is tuned to be quiet at low vehicle speeds, when the fan could more easily be heard by the occupants. Escalade aesthetic The Escalade Hybrid retains the qualities that have made it the leading large luxury SUV and a standard-bearer of Cadillacs overall product renaissance. It is instantly identifiable as a Cadillac and incorporates styling cues from the landmark Sixteen concept vehicle, including a detailed signature grille, front fender vent ports and layers of chrome accents. The Escalades warm and inviting interior features a premium layout. It is available in two colors, Ebony and Cashmere. Standard features include a distinctive instrument panel; gauges with white needles and blue light inlays with continuously lit, white-LED backlighting; Nuance leather-covered seats; leather-covered door trim and center console; and a power-assisted rear liftgate that opens and closes with the touch of a button. |
