While the combination of smaller engines and turbocharging is all the rage in automotive engines now abouts, GM has taken something of an opposite approach with an all-new and larger V-6 engine. The new engine will see its first application in the 2013 GMC Terrain Denali, which itself is the introduction of GMC’s premium trim line to the brand’s compact crossover-SUV.

The new 3.6-liter V-6 engine in the GMC Terrain Denali replaces the Terrain’s current 3.0-liter V-6, and with 301 horsepower and 272 lb-ft of torque eclipses the older engine’s performance. However, with technology including direct injection and continuously variable valve timing, the 3.0 is expected to have a fuel economy rating matching the three liter.

The V-6 engine introduced in the Terrain Denali has an integrated cylinder head/exhaust manifold design, similar to that used on Chrysler Group’s 3.6-liter Pentastar V-6. The GM engine saves about 13 pounds compared to a non-integrated design. The new GM V-6 also has a composite intake manifold which is about 5.5 pounds lighter than an equivalent aluminum intake counterpart. A lightweight structural front cover and high-strength connecting rods also save weight.

Compared with the new Chrysler Group’s six, the new GM 3.6-liter V-6 comes out just ahead in output, the Pentastar engine in the Dodge Charger, for example,  at 292 horses and 260 lb-ft of torque. The Chrysler Group’s engine, however, is paired with an eight-speed transmission instead of the GM gearbox that has a mere six speeds.

In addition to the new engine, however, the 2013 GMC Terrain Denali will get a number of special exterior design cues, including a Denali chrome grille, body color front and rear fascias, new headlamp and taillamp designs and dual chrome finish exhaust outlets. Inside, befitting a GMC’s premium trim line, the Terrain Denali will feature soft-touch Jet Black leather with contrast stitching on the seats and door inserts, smoked mahogany wood trim accents, illuminated front sill plates, eight-way power driver and passenger seat and more.

Not surprisingly, the 2013 GMC Terrain Denali will be loaded with GM’s tech features, including GM’s Intellilink infotainment system, forward collision alert and lane departure warning, blind zone and rear cross traffic alert and again, more.

The new 3.6-liter V-6 will also be available in non-Denali GMC Terrain models, and the 2.4-liter four-cylinder Terrain will continue as the base model.

Buyers will have to wait until the third quarter of 2012, however, before taking home 2013 GMC Terrain Denali, with pricing not available until closer to the vehicle’s arrival in dealer showrooms.
