While saving fuel, you're also reducing emissions. Ford notes that the Escape Hybrid qualifies for super-low (SULEV) or advanced technology partial-zero (ATPZEV) emission vehicle status, and says you can drive the Escape Hybrid 15,000 miles and generate only one pound of smog-forming emissions.
The Ford Escape Hybrid is unique among hybrid vehicles in that its battery pack comprises a tray of what appear to be dozens and dozens of C cells, except they are high-tech nickel-metal hydride batteries and provide 330 volts of power, equivalent to 87 more horsepower. The battery pack is in a sealed box located beneath the rear cargo floor and does not intrude on the Escape's cargo-carrying capability. The battery pack also is warranted for eight years or 100,000 miles.
The batteries do add some weight to the rear of the vehicle, but in the case of the Escape that weight makes the hybrid better balanced than the standard V6 Escape. The Escape V6 has 61 percent of its mass carried by the front wheels. The Escape Hybrid is better balanced. Only 57 percent of its weight is in front. That means this version is more neutral in its handling, staying flatter through corners and under braking. This should provide better maneuverability in emergency situations and enhance front tire and brake wear as well.
The Escape Hybrid's gasoline engine is a 2.3-liter, inline four-cylinder that operates under what is known as the Atkinson cycle, a technology designed to enhance the quality of fuel combustion. The Atkinson cycle sacrifices some horsepower, but keeps intake valves open longer and operates under a higher compression ratio.
The 2.3-liter Duratec four in the standard Escape provides 153 horsepower, 20 more than the Atkinson cycle engine, but the electric motor gives the hybrid power very similar to the Escape V6, which is rated at 200 horsepower.
To waste as little of the engine's power as possible while transmitting it to the drive wheels, Ford equips the Escape Hybrid with a continuously variable transmission. This transmission doesn't have standard gears. Instead, it has metal bands that adjust to best match the engine's performance. Thus there is not hesitation as gears shift, just smooth acceleration.
The CVT does offer a low range setting for increased traction. All-wheel drive gives the Escape Hybrid capability in foul weather and off-highway. Next Page
