TheGroup is throwing out design cues — the cab-forward look of its large cars and doing the once unthinkable — affixing the Jeep brand on all-wheel-drive (AWD) vehicles. Some future Jeeps could be developed with less offroad-oriented AWD instead of 4-wheel drive (4WD). While Wrangler will always retain the ability to cross the ultra-rugged Rubicon Trail, Chrysler Group Design Chief Trevor Creed says not every Jeep has to pass that test to join the family. Jeep could have four different branches — Wrangler, 4WD Liberty, 4WD Grand Cherokee, and AWD models, Mr. Creed says. Both the Liberty and Grand Cherokee conquered the Rubicon. Meanwhile, the Chrysler and Dodge brands are preparing to retire cab-forward styling for the large car family when the next generation bows. The '04 models have been designed from scratch, and Chrysler officials say they are anxious to see public reaction.
