Engine

“General Motors claims the diesel has so much torque to work with that more gears aren’t necessary, but that seems dubious. Although it is true that the 1.6-liter turbo-diesel four’s 240 lb-ft of torque is substantial (its 137 horsepower less so), the same engine is bolted to the newer nine-speed transmission in the Chevrolet Cruze diesel. And that combination does a better job of keeping the engine at lower revs, where it’s quieter and still makes good power.”- caranddriver

Engine and Transmission

2018 GMC Terrain Diesel flaunts a 1.6L I4 engine. It generates 137 horsepower, lowest in the league, along with a remarkable 240 lb.-ft. of torque, maximum in the league.

Interior

“The interior is attractive and well-configured, but some controls are awkwardly placed. Taller drivers will want the steering wheel to extend farther.

GMC Terrain Diesel VS Jeep Cherokee Overland

Boasting a 2.4L i4 engine, Jeep Cherokee Overland is the most expensive ride among its class rivals. The ride comes with an opening bid of $34,095. The 2.4L engine is rated for generating 184 horsepower and 171 lb.-ft. of torque. It is coupled with a 9-speed automatic transmission.

GMC Terrain Diesel VS Nissan Rogue SL

A 2.5L i4 engine is coupled with a CVT mode in Nissan Rogue. The ride flaunts 170 hp of power and 175 lb.-ft. of torque. Nissan Rogue is yet another slow-mover in the league, with a requirement of 9.7 seconds for accelerating to 60 MPH. Its base price is $31,180.

Nissan Rogue offers an excellent combined fuel economy of 29 mpg. Furthermore, the ride has an excellent ground clearance of 7.8 inches. Rogue offers the most spacious front seats in the league with headroom and legroom, respectively of 41.6 and 43 inches.

 

Final Verdict

2018 GMC Terrain is an excellent crossover SUV that is rightfully one of the top performers in its segment. The ride’s biggest perk is probably its excellent combined fuel economy of 32 mpg. Even the engine power is subpar, the total torque delivered is more than merely impressive.

To further make the deal lucrative, there are several optional upgrades available. All in all, 2018 GMC Terrain Diesel is an excellent crossover SUV that has an excellent ground clearance. Though not as sporty as some of its rivals, the ride offers one of the comfiest, poised riding experience.
