To celebrate the brand's 75th anniversary, there are several special editions of the Grand Cherokee available this year, including the Laredo and 75th anniversary Limited edition. And don't you dare forget about the beastlike SRT and its 475 horsepower. At the other end of the spectrum, the 3.0-litre EcoDiesel V6 is appreciated for its fuel economy, as is the 3.6-litre V6, but a lot of people also like the 360-horsepower, 5.7-litre V8's moxie.
