    Quick Review: 2012 GMC Terrain SLT-2



    William Maley

    Staff Writer - CheersandGears.com

    July 20, 2012

    Back in January, Drew got his hands on a 2012 GMC Terrain SLT-2 AWD with the 3.0L V6. Seven months later, I have almost the same GMC Terrain, right down to the black paint.

    However, Drew has driven the Terrain and its platform mate, the Chevrolet Equinox before. This would be my first go with it.

    After a week, what would I think about the Terrain?

    Has anything changed since the Terrain's last visit to C&G Garage?

    Only a few items of note. In the infotainment department, the Terrain dropped its base radio and replaced it with a large, seven-inch touchscreen radio. Also, GMC's Intellilink which provides smartphone integration, and the ability to stream Pandora and Stitcher Internet Radio is now on the option list.

    Also on the options list (only for the SLT-2 model though) is lane departure warning and forward collision alert.

    The Outside & Inside Story


    Exterior

    The Terrain definitely fits the "Professional Grade" persona that GMC puts out there. The front end features a large, bold chrome grill that lets everyone know what you're driving. A pair of large, square headlights and a uniquely sculpted hood complete the front. The side profile features prominent front and rear fenders, body cladding running along the bottom of the doors, and a set of five-spoke, eighteen-inch chrome wheels. The back end has a set of taillights that flank a large chrome bar hiding the release for the hatch and a rear-view camera. Also featured on the rear are twin exhaust pipes.

    However, the designers pumped up the fake testosterone too much and the end result looks like it is trying too hard to fit the Professional Grade persona.

    Given the choice between the Terrain and the Chevrolet Equinox, I would choose the Equinox every time.

    Interior

    Stepping into the Terrain's interior, I was amazed as to how much interior space there was for passengers. Front seat passengers get a pair of heated leather seats, with the driver getting eight-way power-adjustments. Back seat passengers will have nothing to complain about with Terrain as head and legroom are well above average. Also, back seat passengers can also recline and move the seat backwards and forward. Cargo space for the Terrain measures at 31.6 cu.ft. with the seats up and 63.9 cu.ft. with the seats down.

    As for the Dash, build quality and materials are good. The center stack is laid out well and most of the controls are in easy reach. The only set of controls that I would move is for the trip computer. The buttons are set too low in the stack for easy reach. I would put them onto a stalk on the steering wheel column like other GM vehicles.

    The Terrain comes with a variety of infotainment options, ranging from a standard seven-inch touchscreen radio that provides AM/FM/SiriusXM/CD and USB input to a Naviagtion system with a 10 GB hard drive for music. This particular Terrain came with GMC's Intellilink system. Like the Chevrolet Malibu Eco and Buick Verano, I had a couple of problems (iPod playback at Alvin & Chipmunks speed on certain tracks and Pandora playing without sound).

    Powertrain, Ride, Safety, and Verdict


    Drivertrain

    The Terrain comes with the choices of a 2.4L direct-injection four-cylinder or a 3.0L direct-injection V6 engine, and front-wheel or all-wheel-drive. This Terrain is equipped with the 3.0L DI V6 producing 264 horsepower and 222 lf-ft of torque and all-wheel drive. No matter which engine or drive configuration you choose, the only transmission available is a 6-speed automatic. The 3.0L V6 makes its 222 lb-ft of torque at a high 5100 RPM leaving the crossover's transmission constantly on the hunt for the right gear. Making a pass requires a lot of planning.

    gallery_0_439_424649.png

    Fuel economy for the V6-AWD is 16mpg city and 23mpg highway, which shockingly, is identical to the more powerful, larger, and heavier GMC Acadia V6 AWD. Somehow, I was able to coax out 21 MPG for my average.

    If you want/need V6 power in your Terrain, wait for the 2013 models with the 3.6L DI V6 to begin rolling out.

    Ride & Drive

    Driving the Terrain is very a pleasant experience. The suspension does a good job of providing a comfortable ride and isolating road imperfections.

    Also, the suspension does a good job of keeping the Terrain stable in cornering and emergency maneuvers. As for the steering, it is weighted just right.

    Noise from the engine and the road is kept to a minimum thanks in part to triple door seals, double pane glass, and other sound deadening materials.

    Safety

    This particular Terrain was equipped with the optional lane departure warning and forward collision alert. Using a camera mounted in the rear-view window, the two systems warn you if you're drifting into another lane or are about to run into the back of a vehicle. In theory, both systems should work very well. In practice, one out of two isn't bad.

    The lane departure warning is more a nuisance than a help, just a warning light and audible beep. Also, a study from HLDI found out vehicles equipped with lane departure warning were in more accidents than vehicles without the system. The forward collision alert is a good system, flashing a big, red light on the dash and beeping. The system also prepares the braking system for the driver to hit the brakes quickly.

    One item I do have to give GMC kudos for is the dual mirrors for the side-view mirrors, which helps minimize the Terrain's blind spots.

    Verdict

    The GMC Terrain is one of the best CUVs on sale today. Despite my dislike for the exterior styling, most of the overall package is just right for most crossover buyers.

    There is an Achilles heel though to the Terrain and that is the optional 3.0L V6. The power isn't quite where you want it in certain situations, the six-speed automatic hunts for gears, and fuel economy makes you think you're driving a larger vehicle. This is a case of right car, wrong engine.

    For most buyers, the 2.4L Ecotec four is all you need. For those who need V6 power, wait till the 2013 Terrain comes with the 3.6L V6. You'll sacrifice nothing in fuel economy but gain more horsepower and torque.

    Great review, I do Disagree with you as the Chevy Twin is way to Female for me. The Terrain is awesome looking.

    Still Wish GMC would make a Black Diamond edition.

    Metallic black paint with lots of clear coat, Black Chrome rims, all body chrome is black chrome and then black out windows. I think that would be a perfect package.

    I do agree after having driven one a couple months back at a dealership when my son was shopping around, I was disappointed in the V6 and would say the 4 is more than enough for now and people who want the power should wait for the 2013.

    Solid review.

    The Terrain is extremely well sorted, and although I didn't first like the look, in person, on the road, and especially after one was added to the family, I think it looks great where the Equinox is well done but blands out for me.

    My mother is up to about 23k+ on her 2011 SLT-1 AWD with the 3.0L, and having put more miles on it faster than any previous vehicle, zero issues and still pleased with the 3.0L smoothness, power and fuel economy. Continues to do well on fuel, especially versus the 3.6L in her Camaro before, and the 3.0L is a butter smooth revver. Doesn't initially seem torquey but likes to rev and moves smoothly. Now if only it had rear seat vents for the HVAC, their only complaint. Large inside and can get hot/cold in the back seat area.

    Black & chrome. Sharp tester.

    I just bought a Carbon Black Metallic 2012 Terrain nearly identical to the one used for this review. Mine doesn't have the lane departure warning or the front-end collision alert. I've only had it for 2-3 weeks, but I'm very pleased. The 3.0 liter is smooth and the ride is decent even over rough roads.

    I traded my '08 Equinox Sport with the DOHC 3.6 VVT V6. The 3.0 has the same 264 HP, but it does not have the torque available at lower rpm's that I'm used to (the Equinox had 250 lb ft available at 3200 rpm).

    I would have gotten the 2013 Denali with the new 301 HP V6, but the deal on the SLT was too good to pass up. If mpg is not your chief concern and you want better than average performance with SUV functionality and a well appointed interior choose the 2012 SLT with the 3.0 liter. The 2013 gives you the optional 3.6 with sports car-like performance (standard on the Denali). The Denali gives you more Chrome trim, wood accents inside and a few more features including an 8-way power passenger seat.

    I missed this one before.

    I agree with almost all that is stated.

    The styling is subjective as you either love it or hate it. I at fiirst hated this thing but once I really started to compare the Nox andTerrain the Terrain grew on me. It is almost like you crossed a Torrent and a Hummer. Ther is no right or wrong you either like the Nox or the Terrain and that is just what both are supposed to do.

    The tranny is fine and does not hunt once you learn to drive the vehicle and the engine in the sweet spots. The 3.0 and 3.6 need to be driven with RPM, The engine pulls from 3,000 to 6,000 RPM and if you keep the revs up it does not jump around. THe tranny will drop down in gear once you are moving but you need to apply the gas and it will kick down to 3rd gear and move back through them in a smooth undetected manor. This thing is just does not drive like a Small block with a Turbo 350.

    The lane departure and collison detector is a pain in the ass. The lane detector likes to go off often on secondary roads that are not wide. It is ok on the interstate of state highways. We leave this off all the time anymore. It was the first thing the wife said to shut off.

    The collision alert is a little better. It still has some false detections that can catch you when you are not ready. It does activate the brake system or trottle as the car seems to feel like it studders and loses power or the brakes start to apply. I am not sure what it is doing but the forward motion is lost just slightly. This is not a good thing under false alarm conditions. This is the poor mans system and is not as advanced as the Cadillac. We keep this system on but at the lowest setting. Knowing what I do now I would delete it if I could.

    Mileage is good but not great,. But at over 4000 pound it is very acceptable. If you want more MPG buy something less than 2 tons.

    I just checked out a Denali today and I am glad I did not wait for it. It is nice but not worth the extra cost. The is just little value int he Denali package vs what you get in the SLT2.

    The 3.6 is nice and the extra power is always welcomed but the percentage of power increase is small and it is not enough power to make me regrett getting the 3.0. The 3.6 should have been there in the first place but The 3.0 is not a bad engine either.

    The 8 way passenger seat is not really a factor with us as once the passenger seat is set we never change it power or not.

    Over all we are very happy and the only thing that is sad is they deleted the Mocha Steel color that we have. It was one of the most popular colors too.

      Big November Gains at Chevrolet, Buick, GMC and Cadillac Keep GM the Fastest Growing Automaker
      November U.S. retail market share highest since 2009 Year to Date U.S. Retail Share up 0.5 Percentage Points November Commercial sales were highest since 2008 DETROIT — General Motors (NYSE: GM) sold 197,609 vehicles in November to individual or “retail” customers in the U.S., up 8 percent from last year. Based on initial estimates, GM once again outperformed all full-line manufacturers, led by strong retail sales gains at Chevrolet, Buick, GMC and Cadillac. GM’s November retail sales performance drove GM’s U.S. retail share to its highest November level since 2009.
      Based on initial estimates, GM’s retail market share jumped 0.3 percentage points in November to 16.8 percent.  GM has gained retail market share in 17 of the past 20 months.
      GM’s four U.S. brands posted strong retail sales results in November compared to last year.
      Chevrolet — up 5 percent for its best November since 2004 Buick — up 22 percent for its best November since 2003 GMC — up 9 percent for its best November since 2001 Cadillac — up 17 percent for its best November since 2013 GM’s total U.S. sales in November were 252,644 vehicles, up more than 10 percent from last year.   All four brands outperformed the industry in November with Buick, Cadillac and GMC posting double-digit gains.
      “GM’s November performance reflects the continued strength of our U.S. business.  We gained profitable retail share, commercial and small business deliveries were strong and we commanded the industry’s best average transaction prices,” said Kurt McNeil, GM’s vice president of U.S. Sales Operations. “We are ahead of plan selling down our 2016 model year inventory and we expect to close out December with more retail share growth. GM is heading into 2017 in a position of strength with the planned launch of key new products, like the all-new Chevrolet Equinox, into the heart of the market.” 
      GM’s ATPs, which reflect retail transaction prices after sales incentives, were $35,767 in November, more than $4,000 above the industry average and ahead of last November. 

      Through the first 11 months of the year, GM’s U.S. retail sales were up nearly 2 percent compared to last year. GM gained 0.5 percentage points of U.S. retail market share during that timeframe, the largest retail share gain of any full-line automaker. Year to date, Chevrolet U.S. retail sales are up nearly 3 percent and the brand’s retail share has grown 0.5 percentage points to 11.1 percent. Chevrolet continues to be the U.S. industry’s fastest-growing brand.
      Year to date, Buick retail deliveries have grown more than 5 percent and Buick has gained 0.1 percentage points of retail share.
      GM continues to benefit from a strong U.S. economy and strong retail demand for its products.
      “All economic indicators show significantly improved optimism about the U.S. economy including consumer and business sentiment, which continue to drive a very healthy U.S. auto industry,” said Mustafa Mohatarem, GM’s chief economist. “We believe the U.S. auto industry is well-positioned for sales to continue at or near record levels into 2017.”

      Over the weekend, General Motors published and then deleted the power figures for the new 6.6L Duramax Diesel V8 that would be appearing in the 2017 Chevrolet Silverado HD and GMC Sierra HD. Today at the Texas State Fair, GM revealed everything about this new engine.
      We'll begin with the most important detail, power output. The numbers that GM revealed match the numbers posted to their powertrain site - 445 horsepower and 910 pound-feet of torque. Compared to the current Duramax V8, the new engine produces 48 more horsepower and 145 more pound-feet of torque.
      How was GM able to pull this off? They basically went through the engine with a fine tooth comb and made various changes. GM says 90 percent of this engine has been changed. Some of the changes include new electronically controlled, variable-vane turbocharger, revised cylinder heads, improved cooling, and revised fuel delivery system. The updated Duramax can also run B20 bio-diesel.
      Figures for payload and towing will be announced at a later date.

      DALLAS — Chevrolet today announced the redesigned Duramax 6.6L V-8 turbo-diesel offered on the 2017 Silverado HD. This next-generation redesign offers more horsepower and torque than ever — an SAE-certified 445 horsepower (332 kW) and 910 lb.-ft. (1,234 Nm) — to enable easier, more confident hauling and trailering.
      Along with a 19 percent increase in max torque over the current Duramax 6.6L, the redesigned turbo-diesel’s performance is quieter and smoother, for greater refinement. In fact, engine noise at idle is reduced 38 percent.
      “With nearly 2 million sold over the past 15 years, customers have forged a bond with the Duramax diesel based on trust and capability,” said Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”
      The new Duramax 6.6L shares essentially only the bore and stroke dimensions of the current engine and incorporates a new, GM-developed control system. The Duramax’s signature low-rpm torque production hasn’t changed and still offers 90 percent of peak torque at a low 1,550 rpm and sustains it through 2,850 rpm.
      “Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway — with or without a trailer.”
      Additional highlights include:
      New, stronger cylinder block and cylinder heads New, stronger rotating and reciprocating assembly Increased oil- and coolant-flow capacity New EGR system with single cooler and integrated bypass New electrically actuated/electronically controlled turbocharging system All-new advanced solenoid fuel system All-new electronic controls New full-length damped steel oil pan that contributes to quietness New rocker cover/fuel system acoustical treatments B20 bio-diesel compatibility SAE-certified 445 net horsepower (332 kW) at 2,800 rpm SAE-certified 910 net lb.-ft. of torque (1,234 Nm) at 1,600 rpm A new, patent-pending vehicle air intake system — distinguished on the Silverado HD by a bold hood scoop — drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult conditions, such as trailering on steep grades. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.
      The intake design is another example of the advanced integration included in the 2017 Silverado HD that makes it over-the-road capable.   
      A strong foundation
      As with previous versions, the new Duramax block features a strong cast-iron foundation known for its durability, with induction-hardened cylinder walls and five nodular iron main bearings. It retains the same 4.05-inch (103mm) and 3.89-inch (99mm) bore and stroke dimensions as the current engine, retaining the Duramax’s familiar 6.6L (403 cu.-in./6,599 cc) displacement.
      A deep-skirt design and four-bolt, cross-bolted main caps help ensure the block’s strength and enable more accurate location of the rotating assembly. A die-cast aluminum lower crankcase also strengthens the engine block and serves as the lower engine cover, while reducing its overall weight.
      The new engine block incorporates larger-diameter crankshaft connecting rod journals than the current engine, enabling the placement of a stronger crankshaft and increased bearing area to handle higher cylinder loads.
      An enhanced oiling circuit, with higher flow capacity and a dedicated feed for the turbocharger, provides increased pressure at the turbo and faster oil delivery. Larger piston-cooling oil jets at the bottom of the cylinder bores spray up to twice the amount of engine oil into oil galleries under the crown of the pistons, contributing to lower engine temperature and greater durability.
      A new, two-piece oil pan contributes to the new Duramax’s quieter operation. It consists of a laminated steel oil pan with an upper aluminum section. The aluminum section provides strength-enhancing rigidity for the engine, but a pan made entirely of aluminum would radiate more noise, so the laminated steel lower section is added to dampen noise and vibration.
      There’s also an integrated oil cooler with 50 percent greater capacity than the current engine’s, ensuring more consistent temperatures at higher engine loads.
      Segment firsts
      Re-melt piston bowl rim Venturi Jet Drain Oil Separator Closed-loop glow plug temperature control Stronger pistons with remelt
      A tough, forged micro-alloy steel crankshaft anchors the new Duramax’s stronger rotating assembly. Cut-then-rolled journal fillets contribute to its durability by strengthening the junction where the journals — the round sections on which the bearings slide — meet the webs that separate the main and rod journals.
      The connecting rods are stronger, too, and incorporate a new 45-degree split-angle design to allow the larger-diameter rod bearings to pass through the cylinder bores during engine assembly. They’re forged and sintered with a durable powdered metal alloy, with a fractured-cap design enabling more precise cap-to-rod fitment. 
      A new, stronger cast-aluminum piston design tops off the rotating assembly. It features a taller crown area and a remelted combustion bowl rim for greater strength. Remelting is an additional manufacturing process for aluminum pistons in which the bowl rim area is reheated after casting and pre-machining, creating a much finer and more consistent metal grain structure that greatly enhances thermal fatigue properties.
      Additionally, the Duramax’s pistons don’t use pin bushings, reducing reciprocating weight to help the engine rev quicker and respond faster to throttle changes.
      Lightweight cylinder heads, solenoid injectors
      The redesigned engine retains the Duramax’s signature first-in-class aluminum cylinder head design, with six head bolts per cylinder and four valves per cylinder. The aluminum construction helps reduce the engine’s overall weight, while the six-bolt design provides exceptional head-clamping strength — a must in a high-compression, turbocharged application.
      A new aluminum head casting uses a new double-layer water core design that separates and arranges water cores in layers to create a stiffer head structure with more precise coolant flow control. The heads’ airflow passages are also heavily revised to enhance airflow, contributing to the engine’s increased horsepower and torque.
      The Duramax employs a common-rail direct injection fuel system with new high-capability solenoid-type injectors. High fuel pressure of 29,000 psi (2,000 bar) promotes excellent fuel atomization for a cleaner burn that promotes reduced particulate emissions. The new injectors also support up to seven fuel delivery events per combustion event, contributing to lower noise, greater efficiency and lower emissions. Technology advancements enable less-complex solenoid injectors to deliver comparable performance to piezo-type injectors.
      Electronically controlled, variable-geometry turbocharging system
      A new electronically controlled, variable-vane turbocharger advances the Duramax’s legacy of variable-geometry boosting. Compared to the current engine, the system produces higher maximum boost pressure — 28 psi (195 kPa) — to help the engine make more power, and revisions to enhance the capability of the exhaust-brake system.
      Along with a new camshaft profile and improved cylinder head design, the Duramax’s new variable-vane turbocharger enables the engine to deliver more power with lower exhaust emissions. It uses a more advanced variable-vane mechanism, allowing a 104-degree F (40 C) increase in exhaust temperature capability. The self-contained mechanism decouples movement from the turbine housing, allowing operation at higher temperature. That enables the engine to achieve higher power at lower cylinder pressure. Additionally, it has lower internal leakage, allowing more exhaust energy to be captured during exhaust braking.
      The integrated exhaust brake system makes towing less stressful by creating added backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life.
      Venturi Jet Drain Oil Separator
      A new Venturi Jet Drain Oil Separator employed with the Duramax 6.6L is the first of its type in the segment and is designed to ensure oil control in sustained full-load operation. The totally sealed system collects the fine mist of oil entrained in the blow-by gas and uses a small portion of the boosted air generated by the turbocharger to pump the collected oil back to the engine oil sump for re-use by the engine. Less sophisticated systems are not able to return this oil during full-load operation, which can result in oil carryover into the cylinders during combustion.
      Cold Start System
      The new Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance in fewer than 3 seconds in temperatures as low as -20 degrees F (-29 C) without a block heater. The system is enhanced with ceramic glow plugs and automatic temperature compensation — a first-in-class feature providing improved robustness and capability. The automatic temperature compensation assesses and adjusts the current to each glow plug for every use, providing optimal temperature for cold start performance and durability.     
      Electronic throttle valve and cooled EGR
      Unlike a gasoline engine, a diesel engine doesn’t necessarily require a throttle control system. The Duramax 6.6L employs an electronic throttle valve to regulate intake manifold pressure in order to increase exhaust gas recirculation (EGR) rates. It also contributes to smoother engine shutdown.
      Additionally, a cooled exhaust gas recirculation (EGR) system enhances performance and helps reduce emissions by diverting some of the engine-out exhaust gas and mixing it back into the fresh intake air stream, which is fed through the cylinder head for combustion. This lowers combustion temperatures, improving emissions performance by reducing NOx formation.
      The exhaust is cooled in a unique heat exchanger before it’s fed into the intake stream through a patented EGR mixing device, further improving emissions and performance capability. An integrated bypass allows non-cooled exhaust gas to be fed back into the system to help the engine more quickly achieve optimal operating temperature when cold.
      B20 Biodiesel Capability
      The new Duramax 6.6L is capable of running on B20 biodiesel, a fuel composed of 20 percent biodiesel and 80 percent conventional diesel. B20 helps lower carbon dioxide emissions and lessens dependence on petroleum. It is a domestically produced, renewable fuel made primarily of plant matter — mostly soybean oil.
      Manufacturing
      The new Duramax 6.6L turbo-diesel engine is produced with locally and globally sourced parts at the DMAX Ltd. (GM’s joint venture with Isuzu) manufacturing facility in Moraine, Ohio.
      Allison 1000 Automatic Transmission
      The proven Allison 1000 six-speed automatic transmission is matched with the new Duramax 6.6L. A number of refinements have been made to accommodate the engine’s higher torque capacity, including a new torque converter.
      The Allison 1000’s technologically advanced control features, such as driver shift control with manual shift feature and a patented elevated idle mode cab warm-up feature, haven’t changed. Also, the Tow/Haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.
      There’s also a smart diesel exhaust brake feature that enhances control when descending steep grades.
