GMC Tests Out How Automotive Christmas Decorations Affect Performance 15
Posted by Michael Gauthier in Film, GMC, GMC Terrain, GMC Videos, video on 12 15th, 2017

Christmas is right around the corner but General Motors is going all Scrooge and pointing out the obvious, decorating your car is a bad idea.

As part of this year’s Christmas celebrations, the company sent aerodynamic performance engineer Joel Ruschman to the Lockheed Martin low speed wind tunnel in Georgia to test out a GMC Terrain Denali with an assortment of holiday decorations.

According to USA Today, reindeer antlers and a big red “nose” increase the Terrain’s drag coefficient by three percent and this causes the crossover’s fuel economy rating to drop by about 1 mpg on the highway.

While a big bow might not seem like it would have much effect, it actually increased drag by 15% and caused the fuel economy rating to drop by 3.5 mpg. However, the biggest offender was a Christmas tree which caused a 70% increase in drag.

If you can’t resist the urge to decorate your car, the best choice would be a wreath as the wind tunnel tests determined it didn’t have any effect on the Terrain’s fuel efficiency.

Speaking of mileage, the 2018 Terrain Denali has a turbocharged 2.0-liter four-cylinder engine that develops 252 hp (187 kW) and 260 lb-ft (352 Nm) of torque. It is connected to a nine-speed automatic transmission which can be paired to an optional all-wheel drive system. In the latter configuration, the crossover returns 21 mpg city and 26 mpg highway.


GMC Sierra Desert Fox Resurfaces Among The Dunes Of Dubai 21

All sorts of outlandish things happen among the sands of Dubai. We don’t always hear about them, but this one has blipped on our radar.

It’s the GMC Sierra Desert Fox, a concept truck showcased at the Dubai Motor Show. It’s sort of like a Ram Rebel or Toyota Tundra TRD Pro, but with a heavy dose of retro thrown in.

The truck harkens back not to the Nazi general Erwin Rommel (who was known by that nickname) but to the Desert Fox editions that GMC offered in the 1970s, like the vintage Jimmy shown alongside the concept.

That throwback treatment comes down principally to the earth-tone stripes on the beige bodywork, but the rest of it is all hardcore off-roader.

Though official details are even more scarce than official photos, but you can’t miss the chunky tires, bead-lock wheels, jacked-up suspension, low-profile bumpers, nose-mounted winch, side steps, skid plates, custom exhaust, spare tires and jerrycans in the bed, and sports bar with auxiliary LEDs. It even has a pair of hazard flags extending way up high from the roof, all the better to see roaming the dunes of the Arabian peninsula.
