Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.

GMC's electric Hummer could someday serve alongside the Humvee in the U.S. Army

Every civilian Hummer model traces its roots to AM General's Humvee, which made its combat debut when the United States invaded Panama in 1989. Fast forward to the 2020s, and the tables have turned. The born-again Hummer that will arrive with an electric powertrain and a GMC emblem could spawn a military-spec truck. "[The upcoming Hummer] is a full-size truck with 400 miles of range and 1,000 pound-feet of torque, it's a very highly capable vehicle. That could provide a great base platform for an electric vehicle to be used in the military context," said David Albritton, the president of General Motors Defense, in an interview with GM Authority. Although he didn't sketch out the Hummer's role in a battalion, its range, torque, and dimensions would theoretically make it well-suited to carrying soldiers, weapons, and/or gear like radio equipment. It wouldn't necessarily look like the production model (shown above in a preview image). General Motors Defense might use its basic platform and its powertrain technology to build a purpose-designed off-roader, like it did with the Colorado Infantry Squad Vehicle (ISV) it will soon begin manufacturing for the Army. The ISV shares 90% of its parts with the regular-production Chevrolet Colorado, but the two vehicles look nothing alike. Securing a contract with the American military is easier said than done, and Army officials haven't publicly expressed an interest in sending the upcoming Hummer into a war zone. We'll learn more about what a battle-ready electric truck could look like after the showroom-bound model makes its debut. In the meantime, Humvee production continues, and AM General introduced a comprehensively updated model named NXT 360 in 2018. Related Video:     Green GMC Hummer Truck Electric Military

Black Friday could power record November sales

Black Friday allows some shoppers to line up in the wee hours for doorbuster deals on laptops and TVs, but the day after Thanksgiving could mean huge profits for automakers this year, too. Multiple industry analysts predict record growth for the industry for November, and the upcoming incentives could help those numbers. TrueCar predicts that Black Friday incentives could provide a major boost, and it estimates a November sales jump of 3.9 percent from last year to a record for the month at over 1.35 million vehicles. As examples of potential deals, Chevrolet, Buick, and GMC plan to offer up to 20 percent off some models, and FCA US has no-interest financing for up to 75 months from its brands. "Consumers are excited about Black Friday promotions and these month-long events appear to be resonating with car buyers." Eric Lyman, TrueCar's vice president of industry insights, said in the report. Black Friday only recently became a big day for auto sales, according to an analysis from Edmunds. Last year, Thanksgiving weekend posted double the sales as any other weekend in the month. The company predicts a sales volume of over 1.33 million vehicles for November. If that happens, it would be the beat the previous record of 1.32 million sales for the same month in 2001. Some forecasts temper the gains for November but only slightly. Kelley Blue Book predicts flat year-over-year sales at 1.3 million vehicles, but that's largely because there are two fewer sales days in 2015 versus in 2014. "Black Friday deals on vehicles have grown in popularity in recent years, and should be a big contributor to this month's sales results," said analyst Tim Fleming in the study. The combined research from J.D. Power and LMC Automotive have the lowest November prediction among this group at just over 1.279 million sales for the month versus 1.299 million in 2014. However, once the researchers adjust the figures for the two fewer selling days, 2015 could actually be seven percent higher than last year. TrueCar Finds New Auto Sales in November to Reach Monthly Record Black Friday promotions bolster sales gains; industrywide incentives up 6% from last year November 24, 2015 12:11 PM Eastern Standard Time SANTA MONICA, Calif.--(BUSINESS WIRE)--TrueCar, Inc. (NASDAQ: TRUE) projects total new vehicle sales, including fleet deliveries, will reach 1,352,500 units in November, a 3.9 percent increase from a year ago and the highest ever for the month.
