Future Hybrid Cars

Considering the CAFE pressure on trucks and the inherent profit potential in this segment, it's no surprise that most of the hybrid action in the coming years will be in the truck segment. This fall, Toyota will beef up its HSD system for use in the Lexus RX 400h, followed in early 2005 by the Toyota Highlander Hybrid. The technology is identical to the Prius's, but the output of the battery and electric motor will be doubled and a 3.3-liter V-6 will replace the 1.5-liter four. Combined output is said to top 270 horsepower with fuel economy better than the current 27.6-mpg compact-sedan average, which equates to a bladder-busting 600-mile range. All-wheel-drive models will get an additional electric motor powering the rear wheels for improved traction and even quicker acceleration (expect low seven-second times to 60 mph); just don't expect to climb the Rubicon Trail. Toyota may even adapt HSD for use in its forthcoming Tundra-replacement pickup.

This summer, Ford will begin production of an Escape Hybrid, which will team a 2.3-liter four-cylinder engine with a planetary CVT that employs two electric motors much like the Toyota HSD does, except that the all-wheel-drive option will be mechanical, not electric. The hybrid hardware adds 200 pounds, but provides V-6 performance with city fuel economy estimated at 35 to 40 mpg. Trailer towing will be limited to 1000 pounds. Pricing hasn't been set yet, but Ford admits it will be subsidized to some degree.

This fall, Honda will marry its IMA system to a V-6 in the Accord, and the engine will be able to cruise on three cylinders when six aren't needed. The combination is said to provide Civic economy with performance superior to that of the normal Accord V-6.
