New, More Powerful Engine

A new 3.8-liter overhead valve V-6 engine is featured on all 2007 Jeep Wrangler models, replacing the 4.0-liter Power-Tech in-line six engine. With 205 horsepower and 240 lb.-ft. of torque, Jeep Wrangler comes standard with a six-speed manual transmission or an available four-speed automatic transmission.

The 3.8-liter V-6 engine produces more horsepower and torque than its predecessor. Compared to the 4.0-liter inline six-cylinder engine, the 3.8-liter is lighter and shorter, and maintains higher torque at speeds above 3400 rpm, allowing for an expanded operating range.

The all-new 2007 Jeep Wrangler's horsepower and torque, combined with an enhanced suspension, results in a towing capacity of 2,000 lbs. For the first time in a Jeep Wrangler, an optional towing package includes a rear Dana 44 axle with a 4.10 axle ratio and trailer hitch.
