MONTREAL (Thursday, January 16, 2014) – The all-new 2015 Yukon full-size utility and Sierra HD made their Canadian debuts today at the 2014 Montreal International Auto Show.
The all-new 2015 Yukon delivers greater capability and refinement, with more power, new fold-flat rear seats and a quieter interior. And thanks to a new family of advanced EcoTec3 engines, the lineup is expected to deliver the segment’s best V-8 fuel economy.
Bold styling and advanced technologies – including new safety and security technologies – support Yukon’s greater capability, while a more comprehensive list of standard features and enhanced infotainment options are designed to broaden the appeal of one of the industry’s most-popular full-size SUV lineups.
New and enhanced product highlights of the 2015 Yukon lineup include:
- Fold-flat second- and third-row seats that enhance cargo capability and convenience – including an available power-folding feature
- Approximately 50 mm (two inches) more legroom for second-row passengers and easier entry/exit
- All-new cargo management system
- Available power rear liftgate with multiple programmable height settings
- Standard eight-inch-diagonal colour touch screen radio with enhanced IntelliLink and available navigation
- Eight-inch-diagonal customizable driver display with three available user themes and available head-up display (Denali models)
- Multiple USB ports, SD slots and accessory power outlets – including a 110-volt three-prong outlet – to support electronic devices of all kinds
- Conversation mirror in the overhead console that provides a panoramic view of the rear seats
- Keyless entry and push-button start.
Advanced engine technology
The all-new Yukon family is more powerful and efficient than before, thanks to the new EcoTec3 engine family, which debuted earlier this year in the all-new 2014 Sierra. A 5.3L V-8 is standard in Yukon and Yukon XL models and an exclusive 6.2L engine is standard in Denali models, which is expected to deliver the segment’s best horsepower and torque.
The EcoTec3 engines feature state-of-the-art technologies, including direct injection, cylinder deactivation, continuously variable valve timing and an advanced combustion system, designed to make the most of power, torque and efficiency across a broad range of operating conditions. More precisely controlled combustion enables the new engines to run with a higher compression ratio, which delivers greater power and efficiency.
Hydraulic engine mounts, electronic throttle control, adaptive exhaust systems, improved aerodynamics and other technologies help the engines operate in four-cylinder mode for longer periods of time with Active Fuel Management, further increasing efficiency.
Both engines are matched with the Hydra-Matic 6L80 six-speed automatic transmission.
Designed to deliver class-leading capability with enhanced comfort and smarter technologies, the new 2015 GMC Sierra HD lineup advances a 111-year legacy of professional heavy-duty trucks.
The new Sierra HDs arrive in the first quarter of 2014, including 2500HD and 3500HD models, and the Sierra Denali HD, which matches do-it-all capability with an exclusive package of design and upscale interior amenities.
Segment-leading capabilities across the range include the highest payload – 3,508 kg (7,374 pounds) – and the highest conventional trailering rating – 8,890 kg (19,600 pounds). The maximum fifth-wheel trailering rating is 10,523 kg (23,200 pounds). Gas and Duramax diesel powertrains are offered, including a bi-fuel option that pairs the gas engine with a compressed natural gas system.
Additional new and enhanced features for the 2015 Sierra HD lineup:
- CornerStep rear bumper, EZ Lift and Lower tailgate, standard upper tie-downs and other features that make cargo handling easier
- Standard StabiliTrak with Trailer Sway Control on all models, including 3500HD dually
- Integrated cruise control, auto grade braking and diesel exhaust braking (diesel models), for greater driving control and reduced brake wear on grades
- Enhanced cooling airflow, which enables the Duramax turbo diesel and 6.0L gas engine to better maintain full power, even under heavy loads and high ambient temperatures
- Latest-generation IntelliLink infotainment system, which offers a variety of connectivity options for devices of all types and available navigation
Sierra HD models are available with 6’6” and 8’ box lengths that are stronger and more durable, easier to use and offer greater cargo flexibility. The new CornerStep rear bumper – introduced on Sierra 1500 – is standard. It features integrated steps at each corner designed to accommodate large boots, with textured pads for sure-footed grip.
Sierra HD’s boxes also feature four integrated cargo tie-down provisions built into the lower corners and new, standard upper tie-downs. The patented upper hooks – each rated at 113 kg (250 pounds) – can be placed in several locations around the upper bed rails, providing flexibility for securing loads of all shapes and sizes.
The EZ Lift-and-Lower tailgate is standard on SLE, SLT and Denali models. An internal torsion bar in the tailgate reduces the effort to raise and lower it, while a rotary damper allows for a controlled and more gradual lowering motion when opening. The tailgate is also easily removable without tools.
Proven powertrains
A Vortec 6.0L gas V-8 with variable valve timing is matched with the Hydra-Matic 6L90 six-speed automatic transmission as the standard powertrain across the Sierra HD model range. This combination is engineered to deliver excellent performance and efficiency, especially at low-rpms. It is rated at 360 horsepower (268 kW) and 380 lb-ft of torque (515 Nm) in 2500HD models and 322 horsepower (240 kW) and 380 lb-ft (515 Nm) in 3500HD.
The 6.0L engine is also available in a bi-fuel model that features special hardened valves and valve seats that enables it to run on compressed natural gas or gasoline. The CNG fuel system is installed by a GM supplier and completed vehicles are delivered directly to the customer, making the purchase process as seamless as ordering any other option.
The Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 2500HD and 3500HD models, with highlights that include:
- 397 horsepower (296 kW) at 3,000 rpm
- 765 lb-ft of torque (1,037 Nm) at 1,600 rpm
- High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
- Variable vane turbocharger that also acts as an exhaust brake to help control or slow the vehicle’s speed
- Selective catalytic reduction after-treatment system using diesel exhaust fluid injection to provide the best overall diesel characteristics and performance – with a range of about 8,000 km (5,000 miles) between DEF refills
- Combustion and after-treatment optimized to provide about 1,125 km (700 miles) between diesel particulate filter regenerations
- B20 biodiesel capability for an alternative fueling option.
The Allison 1000 features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.
