Like the 911 for Porsche or the Miata for Mazda, the Wrangler defines the essence of what Jeep stands for. For 2007 the quintessential "no muss, no fuss 4x4," is all new and finally gains some on-road manners to go with its off-road prowess.

Five hundred hours of wind tunnel testing and a softer suspension setup give the truck a much more refined ride when not tackling the trails. Thankfully, off-pavement, it's still a no-frills bruiser, with a new fully boxed frame (100 percent stiffer than last year's model), and, for the first time, an electronically disconnected front stabilizer bar, which allows better wheel articulation off-road.

The interior is still utilitarian, though materials and fits are improved and for the first time power windows, locks and keyless entry are offered. There's finally a small under-floor storage bin in the cargo area and DVD navigation is now optional.

The most significant change is the new 3.8-litre overhead valve V6, which replaced the prehistoric AMC straight six. Lighter and shorter, it's a new North-South iteration of the engine from DaimlerChrysler's minivan family, beefed up for Jeep's durability requirements. Making 205 hp and 240 lb-ft of torque, it delivers power over a much flatter curve. A 6-speed manual is standard and a 4-speed automatic is optional.

A more refined icon at a better price

Still too utilitarian for some
