2014 Chevrolet Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.

2015 GMC Yukon Denali

Automotive enthusiasts often wonder aloud - ourselves included - why General Motors would choose to keep GMC while sending Pontiac (and Saturn, and even Oldsmobile before it) into the great automotive graveyard in the sky. The answer, as is so often the case, is profit. It's much easier for GM to rake in money hand over fist by rejiggering the trucks, crossovers and SUVs that it would already be developing for Chevrolet and making them a bit more luxurious and *ahem* "Professional Grade" with new grilles, badges and unique packaging for GMC.
While it may sound like we're being cynical, we totally approve of GM's fullsize SUV strategy. The least-expensive way to get into the fold is with the Chevrolet Tahoe, which starts at $45,595 with a 5.3-liter V8 engine and a cloth interior. Bumping that same Chevy to LTZ trim and its $59,995 sticker price lands a much nicer leather-clad interior and more techno-bells and whistles than you can shake a stick at. But it still looks like a Tahoe, and it still comes with the smaller 5.3-liter engine. Or, you could do what we'd do: Walk into your GMC dealer and take a look at the Yukon Denali. Here's why.

2018 GMC Acadia with 'Christmas Aero' modification gets in the wind tunnel

Tis the season of "Big" - big cheer, big parties, big bowls of eggnog, big decorations, and when it comes to your family hauler, big drag. Festive drivers who festoon their crossovers, minivans, and SUVs with wreaths, Rudolph noses, fuzzy antlers, and rooftop Christmas trees undo the years of work that car engineers devote to fractional gains in fuel economy. To put numbers to such fuel-guzzling madness, GMC started with a 2018 Acadia, optioned it with the Xmas Aero Package - both Standard and Plus versions - put it in Lockheed-Martin's wind tunnel. The resulting dip in fuel economy results probably won't surprise anyone who's used a roof rack - or, for that matter, their car's air conditioning. However, it might surprise you to find out which seemingly substantial decoration had no effect, and which seemingly innocuous decoration was about twice as bad as running the A/C on its Mr. Freeze setting. Check out the brief video above for the results. And consider placement of that bow carefully.
