The standard 285 -
horsepower 3.6 - liter V6 carries
over from the
previous - generation Wrangler (which continues for the 2018
model year as the «Wrangler JK»), but it gets a fuel - saving start / stop feature and is now paired with an 8 - speed automatic transmission in place of the
previous 5 - speed (a 6 - speed manual transmission is available).
