New Cars: Jeep Trailhawk Concept Preview – The Trailhawk is a concept with no true defining vision. Jeep claims it's off-road capable - believable since it's based on the Wrangler Unlimited platform - yet also claiming it's a sophisticated and refined highway cruiser. Which is it? We all know it can’t be both. Is there something in the water at Jeep these days? Make a luxury SUV and it will be terrified of dirt; remember the scene at the end of Cars with the Hummer? On the other hand, tune a vehicle to be trail worthy and the words “refined” and “sophisticated” don’t come to mind.
