Next wave of hybrids getting an exciting new makeover
DETROIT: Fans of the gasoline engine may feel a slight chill as they walk through the exhibits at the North American International Auto Show.
While an ice age for internal combustion engines does not seem imminent, it is clear from the number of hybrid-power vehicles on display here that automakers are reserving their warmest feelings for powertrains that team electric motors with petroleum-burning engines.
The best-selling car in the United States, the Toyota Camry, will add a hybrid option for the redesigned 2007 model that goes on sale this spring. Equally significant, the next Lexus flagship, the LS460, will also join the hybrid fleet, providing a philosophical bookend to the frugal Prius at the other end of Toyotas line. With these additions, Toyota expects its global sales of hybrids to top 400,000 in 2006.
General Motors showed hybrid versions of its large SUVs that will go on sale next year as 2008 models, and announced a Cadillac Escalade hybrid.
Design studies from various automakers suggest that hybrids will be coming in other shapes, too: Ford rolled out a design study for a sporty diesel-hybrid coupe, the Reflex; Mitsubishi showed the CT, a concept car that may hold engineering promise; and Subaru displayed the B5-TPH, a high-performance two-seater.

Even longtime hybrid doubters like Robert Lutz, vice chairman of GM, are admitting that the systems have gone mainstream. “Theyre here, and if weve got to have them, at least we have the most economical one,” he said.
GMs Saturn division will charge customers a premium of less than $2,000 for the “mild” hybrid system in the Vue Green Line utility wagon. The system delivers power directly to the gasoline engine using a motor-generator that replaces the conventional alternator, rather than driving through the transmission. GM says the hybrid Vue will be the lowest-priced hybrid SUV when it arrives in showrooms this summer.
The Vues 42-volt system, using an approach less complex than the high-voltage equipment of other hybrids, shows an emerging diversity in technology – and customer appeal. While early hybrids emphasized environmental benefits, recent entries like the Honda Accord hybrid have played up the boost in acceleration provided by an electric motor; the Vue appeal is a low purchase price.
GM also used the Detroit show to highlight the two-mode hybrid it is developing with BMW and DaimlerChrysler. The system, to be used first in the Chevrolet Tahoe and GMC Yukon, uses electric motors inside the transmission to augment a 300-horsepower V-8. The two drive modes, one for slower city driving and the other for highway cruising, are expected to improve mileage by 25 percent, GM says.
