CADILLAC ESCALADE HYBRID
BODY TYPE: SUV
BASE MSRP: $73,000
The Escalade Hybrid shares the same hybrid system which is used in the Chevrolet Tahoe and GMC’s Yukon hybrid SUVs. The hybrid hardware combines a modified 6.0-liter, 332-horsepower V8 gasoline engine, a 300-volt nickel-metal hydride battery pack and a two mode hybrid transmission that includes two 50-kilowatt motor generators. In order to keep the vehicle running at peak efficiency, this hybrid system is able to run in one of two separate modes—hence the name “two-mode hybrid.”During low-speed, low-impact driving, the powertrain works just like other hybrids, it stops the V8 engine whenever possible so that it may draw power from one or both of the electric motors. With a deft foot on the go pedal, the big SUV can travel under electric power for around two miles at up to 35 mph.
PORSCHE CAYENNE S HYBRID
BODY TYPE: SUV
BASE MSRP: $69,000

TOYOTA HIGHLANDER HYBRID
The gas-electric Highlander was outfitted last year with a 3.5-liter V-6 engine, replacing the 3.3-liter six of its predecessors. The dual-overhead cam Atkinson-cycle engine (a more fuel-efficient version of the traditional four-stroke Otto-cycle engine) is rated at 231-horsepower. In addition, two electric motors join this powertrain, one in the front and one in the rear, boosting the overall horsepower to a very respectable 280. There is a third electric motor that operates solely as an engine starter. The whole system is connected to a continuously variable transmission, which is engineered to manage the various sources of power in a way that maximizes the Highlander Hybrid’s efficiency.
LEXUS RX 450H
Electronic adjustment of Lexus RX 450h when combined with the V-6 is an EPA fuel mileage rating of 32/28 city/highway and 30 combined for the FWD model, while the AWD version has estimates of 30/28/29. That’s the best fuel economy of any luxury SUV available – gasoline, diesel or hybrid.
