2015 Chevy Silverado, GMC Sierra can tow up to 12,000 pounds

Think back to the launch of the 2014 Chevrolet Silverado. At the time, General Motors happily trumpeted that its fullsize pickup could tow up to 11,500 pounds when properly equipped - impressive stuff, no doubt. But now, revised tow rating practices have been put into place, called SAE J2807. And with these new methods of testing, GM can now officially rate both the Silverado and its GMC Sierra twin as being able to tow up to 12,000 pounds.
Of course, not all Silverado and Sierra models are capable of this feat. In fact, because of SAE J2807, most of the truck models have actually had decreases in tow ratings from the 2014 to 2015 model year. For example, a 2014 Silverado Crew Cab with the 5.3-liter V8, 5.7-foot box and 3.73 rear axle was rated at 11,200 pounds in 2014, but has since been reduced to 10,800 in 2015. Same goes for the Sierra.
But for 2015, both the Silverado and Sierra can be had with a more powerful 6.2-liter V8, as well as a Max Trailering Package that includes a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning, improved cooling and a new trailer brake controller. There are also four- and seven-pin, bumper-mounted connectors, a trailer hitch (duh), and a G80 locking rear differential. This configuration, with either model, is the only way you can actually tow 12,000 pounds.

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.

Average transaction prices climb to a record $36,270 in January

The automotive sector made a hash of the numbers last month, a mess of pluses and minuses clogging the transaction-price charts according to Kelley Blue Book. The overall industry rose one percent, even though buyers bought fewer cars and light vehicles in January 2018 vs 2017 using the selling-day adjusted rate. Due to January transaction prices rising to $36,270, a record for January, the value of new vehicles sold climbed more than $1 billion compared to January 2017. KBB's transaction prices don't include customer incentives, which changes the complexion slightly; average incentive spending rose to just over ten percent. The average transaction price in December 2017 was $36,756, so January dropped a bit - nothing unexpected, with the month annually blamed for "January doldrums." More revealing is the fact that the average transaction price in January 2017 was $34,910. This year's plumped-up figure came courtesy of the continued shift to crossovers, SUVs, and light trucks, which shouldn't surprise anyone who's read an automotive blog in the past 20 years. That category comprised nearly 70 percent of new vehicle sales for the month. Some manufacturers profited more than others, though. Fiat Chrysler managed 12.8 percent fewer sales in January compared year-on-year, but the company's vehicles sold for $1,300 more. The Ford brand suffered a 6.3-percent dip in sales, but brand transaction prices increased $2,000, while a Lincoln sold for $8,700 more on average. General Motors sold more cars and sold them for more money; overall GM transaction prices rose four percent, or $1,270, while a GMC traded hands for seven-percent more than in January 2017 and a Cadillac got $2,300 more on average. Of KBB's listed automakers, the Volkswagen Group got the most of out its customers, transaction prices rising at the German automaker by 5.6 percent to $42,243 in January 2018 compared to a year earlier. American Honda followed with a 4.3-percent increase to $28,991, GM in third at 4.1 percent to $40,313. Find your next car at Autoblog using our new and used car listings or the Car Finder tool. Broken out by segment, minivans rocked the table, transaction prices leaping by 7.9 percent to $35,380 compared to January a year earlier. Luxury cars boasted the next-highest rise, at 3.6 percent to $58,533.
