Jeep CJ66: The Jeep CJ66 takes a 1966 Jeep body and mates it to a Jeep TJ frame while adding V8 power for quite the Jeep mixtape.Under the hood is a 383-horsepower, 5.7-liter "Hemi" V8 that pairs to a six-speed manual transmission.If all that power isn't enough, the CJ66 offers a performance exhaust. And it's no slouch off-road, thanks to Mopar Dana 44 Crate axles front and rear.The CJ66 concept is just one among many rock-crawlers and boulder-bashers on display at the 2017 Chicago Auto Show.
