General Motors introduced the 2018 GMC Terrain earlier this year with a new design that features a bold grille, sculpted headlights and C-shaped rear light graphics. Like it’s Chevrolet Equinox sibling, the Terrain is offered with several turbocharged powertrains, most noteworthy being the all-new diesel. Available on SLE and SLT trims, the 1.6-liter turbodiesel engine offers both efficiency as well as performance, generating 240 lb-ft of torque at a very low 2000 rpm.
