Jeep is keeping the final edition of the V8-powered Wrangler 392 (470 horsepower) around for one more year. Meanwhile, the standard 3.6-litre V6 (285 horsepower) can still be paired with the six-speed manual gearbox or, optionally, an eight-speed automatic transmission. Other powertrain options include a turbocharged 2.0-litre four-cylinder engine (270 horsepower) and a plug-in hybrid system (375 horsepower).
