TrueDelta Reviews the Seat Room and Comfort of the 2017 GMC Terrain
| 2017 GMC Terrain Seat Room and Comfort: Pros | ||
| Year | Comment | |
| 2018 | The first-generation GMC Terrain took advantage of a long, 112.5-inch wheelbase to offer exceptional rear legroom--nearly 40 inches of it. On paper, the 2018 Terrain has only a half-inch less combined legroom despite a wheelbase shrink of 5.2 inches (to better align the vehicle with competitors and open up space for the downsized Acadia). In reality, rear legroom seems ample but no longer outstanding. The rear seats in the Honda CR-V and Toyota RAV4 are similarly roomy. But the Terrain does pull ahead when evaluating rear seat comfort. Its high-mounted rear seat cushion provides better leg support than others. The Compass's rear seat is lower and firmer. The Terrain's rear seat can even recline a little. Based on their specs, the Jeep is nearly as roomy inside as the GMC. Headroom, shoulder room, and combined legroom specs all differ by less than an inch. In reality, the Jeep's interior feels significantly narrower. And the Jeep Cherokee? All of its interior specs are also within an inch of the Terrain's, though often in the other direction. Why does Jeep offer two crossovers so close in size? This isn't clear. In terms of specs, they differ most in combined legroom and cargo volume. The Cherokee has 1.3 inches more of the former--good to have, but hardly justification for an additional model--and about ten percent LESS of the latter. How can the larger Jeep have less cargo volume? I suspect that the Compass was measured more creatively, and cannot actually hold as much cargo. Based on their specs--and I always take cargo volume specs with more than a little salt--the new Terrain can swallow a few more cubic feet of cargo than the Compass (63.3 vs. 59.8) but falls well short of the RAV4 (70.6 in hybrid form, 73.4 otherwise). A Honda CR-V can fit a couple more cubes than the RAV4. The GMC Terrain and the Jeeps compensate for not having the most spacious cargo areas with front passenger seats that fold forward. If your cargo is long but not wide, one of these is the way to go. Though closely related to the GMC, the Chevrolet Equinox does not offer this feature. see full GMC Terrain review | |

| Reviewers often praise the low-end torque of diesels, and the 1.6-liter turbo-diesel does out-twist the turbocharged 1.5-liter gas engine by 37 lb-ft (240 vs. 203). But it's still no match for the turbocharged 2.0-liter gas engine's 260 lb-ft. Note the size of the diesel engine. Nearly every other four-cylinder diesel that has been offered in the US in recent memory has been a 2.0-liter (give or take 100 cc). Previously GM also offered a 264-lb-ft 2.0-liter turbo-diesel, in the Chevrolet Cruze sedan. To me, the 2.0 seemed larger than was necessary in the Cruze, especially if maximum fuel economy was the goal. GM apparently agreed, and replaced the 2.0-liter with the 1.6-liter engine, first in the redesigned Cruze and now in the Equinox and Terrain. The thing is, this size engine is less adequate in the crossovers than in the lighter sedan. In the Terrain and Equinox a 2.0-liter diesel engine might have been more apt. The best diesel-compact crossover partnership I've driven was the Mercedes-Benz GLK250 with a 201-horsepower 2.1-liter turbo-diesel. In the GMC's defense, its smaller, less powerful engine yields superior fuel economy ratings, 28/38 vs. 24/33. And that said, in my real-world suburban driving the trip computer averages weren't nearly so far apart. Getting back to performance, the 1.6-liter feels sufficiently strong in nearly all around-town driving, and even somewhat torquey at low speeds. But when more is requested of it, especially at highway speeds, it can't deliver. Like all diesels, the Terrain's 1.6 has a low power peak, its output topping out at 3,750 rpm with 137 horsepower (14 fewer than the old 2.0-liter). The 1.5T gas engine can produce 170 horsepower at 5,600 rpm, while the 2.0T gas engine can produce 252 horsepower--nearly twice as much as the diesel--at 5,500 rpm. (But still well short of the 2017 Terrain's 301-horsepower 3.6-liter V6.) I wasn't impressed with the 1.5T in a Chevrolet Equinox. It got the job done, but never felt quick or responsive. If you want strong acceleration, you want the 2.0T gas engine. Even in typical around-town driving the diesel feels less responsive than even the smaller gas engine. When summoned, the turbocharger takes a moment or two to spin up. Also worth noting: there's a couple-second delay between hitting the start button and the engine starting up, at least in cold weather (temps were in the 20s). With its 180-horsepower 2.4-liter engine, the Jeep Compass feels about as energetic as the Terrain with its base gasoline engine. With the Jeep, though, you have no other options. When pressed, the Toyota RAV4 Hybrid can accelerate significantly more quickly than the Terrain diesel--and more quickly than the regular RAV4--but sounds and feels like it'd rather progress at a more leisurely and more economical pace. The Terrain diesel might be slower, but it never sounds as strained. see full GMC Terrain review | ||
