Ford Escape plug-in prototype shows potential

— -- Automakers are moving fast to determine whether plug-in hybrid electric vehicles can be put onto the market affordably.

PHEVs can up to triple fuel mileage in short trips, and recharging costs less than gas to go the same distance. It appears that plug-ins cut tailpipe emissions more than enough to make up for any pollution caused by the plants that generate the electricity to charge them.

Win-win-win.

"I'll take two," you say. Hold on, sport. Plug-ins require costly additional battery capacity and plug-in rechargers. Regular gas-electric hybrids can't be plugged in and don't have capacity to run battery-only.

Automakers are uncertain how much costlier plug-in hybrids would be over normal hybrids, which, in turn, cost at least $2,000 more than gasoline vehicles.

Still, it's intriguing enough and possible enough to take plug-ins seriously and to drive 'em if you got 'em.

The Escape plug-in hybrid, on display at the auto show in Washington, D.C., this week, is rolling into service at Southern California Edison, where some will go to individuals to measure results in ordinary driving.

Before delivering it to the show, Ford engineers gave USA TODAY wheel time in the front-drive prototype.

Short take: excellent mileage, extraordinarily smooth integration of gasoline and electric powerplants. Escape's aging design hobbles the package overall, but it's likely to be redesigned by the time a plug-in hybrid version would be available.

The idea of PHEVs is to run on battery power as long as possible before hailing the gasoline engine for help, with no gas use or tailpipe emissions for that time.
