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.

Despite strong profits, GM still fighting flat market share

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.
