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.

2017 GMC Canyon steals Cadillac's V6 for a little more power

GMC is fortifying the Canyon with a new powertrain and two new trim levels for 2017. GMC will give the Canyon the 3.6-liter V6 found in the Cadillac ATS, CTS, CT6, and XT5 crossover. The engine will be matched to an eight-speed automatic transmission, which also can be found on Cadillacs, the new 2017 Colorado, and other General Motors vehicles. The new engine comes with variable valve timing, improved direct injection, and Active Fuel Management, which is a form of cylinder deactivation that shuts off two cylinders to increase fuel efficiency and performance. Power is up from 305 to 308 horsepower, while torque increases from 269 to 275 pound-feet of torque compared to the old 3.6-liter V6. With the new transmission, the Canyon benefits from a higher first gear ratio, which should help drivers get off the line more easily when towing large cargo, and lower overdrive ratios for improved fuel efficiency. The 2016 model had a six-speed automatic. The Colorado also gets the eight-speed transmission for '17. GMC previously announced the All Terrain X and Denali models. The All Terrain X trim is offered on the SLE model and comes with the new 3.6-liter V6 engine or the 2.8-liter Duramax turbo-diesel. The All Terrain X gets Goodyear Wrangler DuraTrac P225/65R17 all-terrain tires, a body-color grille surround and matching rear step bumper, bespoke 17-inch aluminum wheels, and a spray-on bedliner. The truck also is fortified with Hill Descent Control and an off-road suspension. The Denali carries the flag as the most luxurious Canyon model and gets a Bose seven-speaker audio system, more chrome, and interior upgrades. In addition to the new models and the powertrain, the 2017 Canyon will be offered with new colors – Dark Slate Metallic, Mineral Metallic, and Red Quartz Metallic – a new IntelliLink radio with a seven-inch touchscreen, a heated steering wheel as an optional extra, and Standard Teen Driver Mode. The 2017 Canyon, with all of its changes, will be available in the fourth quarter of the year.

2025 GMC Sierra EV rumored to offer a smaller 170-kWh pack as standard

It's kind of wild that you can order a 2024 GMC Sierra EV Denali Edition 1 pickup, yet GMC hasn't released specific figures for battery capacity; maybe that's info you only get after putting down a deposit. Adding to the mystery, the 2025 GMC Sierra EV, already being promoted at the GMC site and which will be available later this year, will add a second battery. GM Authority says the pack in the 2024 truck (that only comes in one trim) is the 204-kWh pack we already know from the GMC Hummer EV. In April, GMC raised the estimated range rating for that pack from 400 miles to 440 miles, upped towing capacity by 500 pounds to 10,000 pounds, and raised max payload capacity by 150 pounds to 1,450 pounds. For 2025, GMA says the the Sierra EV range will add a smaller 170-kWh pack for lower trims.  Trims, you ask? Yes, next year's standard Denali trim will be joined by AT4 and Elevation trims. The AT4 will come with trail-use perks like four-wheel steering, CrabWalk, and two additional inches of ground clearance thanks to 18-inch wheels wrapped in 35-inch all-terrain tires, plus Super Cruise and a spray-on bedliner. Optional features on the AT4 include a DC fast charge upgrade to 350-kW, GMC's MultiPro MidGate, and the 10.2-kW Power Station Pro. The Elevation, typically a lower trim in GMC's vehicle lineups, comes with a power-operated frunk, the MultiPro tailgate, and sits on 18-inch wheels in 33-inch rubber. The Elevation options menu will offer the MultiPro MidGate, Super Cruise, spray-on bedliner, Power Station Pro, and fast charge upgrade. The Denali will come with all of these tech features standard, but sit on 24-inch wheels in 35-inch rubber. New colors will expand the palette from the sole option today, Thunderstorm Gray, to include Deep Ember Tintcoat, Deep Ocean Metallic, Moonlight Matte, Onyx Black, and Summit White. Back to the battery, the 2025 Sierra EV's order guide shows two pack options, an Extended Range and a Max Range, without giving capacity figures. GMA believes this will be a 20-module pack of 170 kWh, powering a range of around 380 to 390 miles. The 2025 trucks reportedly begin heading down lines in early September, starting with the Denali trim, so information should be forthcoming in the not-too-distant. The AT4 and Elevation trims will reach dealerships early next year.
