Get the power you need, contained in Wrangler's new standard 3.6L Pentastar® VVT petrol V6 engine. The workhorse for all models is the available 2.8L four cylinder Turbo Diesel engine that provides robust performance and durability. The available new five-speed automatic transmission offers the freedom of smooth hands-free shifting. A six-speed manual transmission comes standard on all models. The Wrangler Electronic Throttle Control system’s special off-road calibration is designed to help the driver “feather in” the throttle over uneven terrain, logs and rocks.
