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.

2014 GMC Sierra 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year. Check out the full press release below for more information.

GM announces net 220 job increase as Trump visits Michigan

GM announced today that about 900 jobs would be added (or, importantly, retained) ahead of President Trump's arrival in Michigan, where he is expected to discuss his plan to roll back fuel economy standards. The timing of the announcement is almost certainly not coincidental, as appending it to a Trump visit gives it a higher profile and dovetails with the President's jobs agenda. It's less likely the decision itself was made for those reasons, but the free PR boost is a nice bonus. As for those 900 jobs themselves, they aren't all new jobs. The only net gain is approximately 220 jobs at the Romulus Powertrain Plant, which produces the 10-speed automatic transmission that's proliferating through the company's lineup. The 180 jobs at Flint Assembly and 500 jobs at Lansing Delta Township are retained jobs – that is to say, spots the company found for workers who would otherwise have been laid off. By the way, the Flint jobs will help with production of heavy-duty pickups, and the Lansing jobs are to produce the Chevrolet Traverse and Buick Enclave. Finding jobs for manufacturing workers in the auto sector, whether new or retained, is admirable. No matter how GM couches it, the company has created or retained a total of 7,000 jobs this year, and its total reinvestment in US production is around $1 billion. But these decisions are business ones, not political ones – timing the announcements to make them seem inspired by economic policy, or the political situation, is simply smart PR.
