2015 Chevy Tahoe

2015 GMC Yukon DenaliGeneral Motors has today unveiled its new family of fullsize SUVs, including the 2015 Chevy Tahoe, its longer Suburban sibling, and their GMC Yukon, Yukon XL and Yukon Denali cousins. More efficient powertrains, improved aerodynamics, increased connectivity and better overall refinement are what Chevy and GMC say will separate their new SUVs from the current generation.

Sporting a tried-and-true body-on-frame architecture, these full-size SUVs feature platforms that are stronger and offer a wider rear track for "a more planted stance," according to Chevy and GMC. Mounted at the front of each SUV is an EcoTec3 powertrain, which consists of a standard 355-horsepower, 5.3-liter V8 (or a 420-hp, 6.2-liter V8 for the GMC Yukon Denali alone) with direct injection, cylinder deactivation and continuously variable valve timing, that's paired with a Hydra-Matic 6L80 six-speed automatic transmission. The setup is said to be more efficient than before, though official EPA fuel economies for each vehicle are not yet available. To help the powertrain achieve the best possible fuel economy in these 5,000+ pound SUVs, the new styling was developed with aerodynamics in mind. For the same reason, electric power steering also makes its debut in the Tahoe/Suburban/Yukon family.

The front fascias of the Chevy Suburban/Tahoe and GMC Yukon are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, which improves aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight. Chevy and GMC also tout that the Tahoe/Suburban and Yukon don't share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks.

2015 Chevy Suburban

More safety features come standard on the SUVs, while others are optional. Chevy and GMC are not clear on what safety features are standard, but they include new radar-based systems such as forward collision alert, front park assist, lane departure warning, lane change assist, rear cross-traffic alert and adaptive cruise control. A Safety Alert Seat, which gives directional vibrations to alert the driver of potential crash threats, is also an option, and all three SUVs offer the segment's only front-seat center airbag.

The interiors of the Chevy and GMC SUVs have been updated, as well. The prior Tahoe/Suburban and Yukon have never featured fold-flat third-row seats - just fold-and-flip seats – but all three now come standard with fold-flat second- and third-row seats, which can be equipped with an optional power-folding feature. Second-row passengers also get two inches more leg room. Multiple USB ports and power outlets are littered throughout their interiors, including one 110-volt, three-prong outlet. The Yukon also includes SD card slots.

Of course, the main differences between the Yukon and Tahoe/Suburban are luxury and refinement. The Yukon is intended to be the more luxurious, "professional-grade" vehicle, and thus GMC customers essentially are paying for higher quality materials and some unique options, especially in Denali trim. The Yukon's interior is nicer, offering seats stuffed with dual-firmness foam, and it has more features, such as a standard Bose sound system and the aforementioned SD card slots. The luxury bias is also reflected in the use of laminated glass for the windshield and front windows, which decreases interior noise. Denali Yukons take that luxury a step further. They're equipped with active noise-cancellation technology and come standard with GM's third-generation magnetic ride control suspension that's available on the Corvette Stingray and many Cadillacs. The high-tech suspension is optional on Chevy's LTZ models.

GMC Introduces All-New, More-Capable 2015 Yukon Family

LOS ANGELES – GMC announced today the all-new 2015 Yukon, Yukon XL and flagship Yukon Denali models will deliver 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. Combined Yukon/Yukon XL and Denali sales were up 24 percent for the eight months of 2013.

"We've engineered the Yukon and Yukon XL from the ground up, building on a strong legacy of capability to take them to the top of the segment with exceptional refinement and purposeful technology," said Tony DiSalle, vice president of GMC Marketing. "And when it comes to the tasks people rely on a full-size SUV for, they do it better than ever – and with more style."

Yukon and Yukon XL share design, architectural and powertrain elements, but Yukon XL has an approximately 14-inch longer wheelbase and is approximately 20 inches longer overall, providing greater legroom for third-row passengers and almost twice the cargo room behind the third-row seat.

"Although they are based on a similar architecture, Yukon and Yukon XL are distinctive products that appeal to different customers," said DiSalle. "Versatility and spaciousness are valued by customers for both vehicles, but the Yukon XL is the choice for families with more children and those with lifestyles that require its unique combination of passenger- and cargo-hauling capabilities. In fact, Yukon XL owners are more than twice as likely to transport passengers daily in the third-row seat."

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 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

When it comes to safety, the Yukon lineup incorporates new technologies to help protect the driver and passengers before, during and after a collision. They include a forward radar system and the segment's only front seat center-mounted air bag (models with bucket seats), which is engineered to provide additional protection to drivers and front passengers in far-side impact crashes, where the affected occupant is on the opposite, non-struck side of the vehicle.

Standard and available safety features, depending on the model, also include forward collision alert, front park assist, lane departure warning, lane change assist, rear cross traffic alert, adaptive cruise control, front and rear automatic braking, and GM's Safety Alert Seat. It offers directional vibrations to alert the driver about potential crash threats.

Bold styling, enhanced refinement
All-new exterior and interior designs advance GMC's professional grade aesthetic with elements designed to be beautiful and functional. The exteriors are sleeker and more aerodynamic, enhancing efficiency on the highway and contributing to the new Yukon's quiet ride.

Bold styling cues include highly detailed, chrome-accented grilles matched with GMC's signature C-shaped light-emitting diode lighting motif, front and rear. Projector-beam headlamps are standard on Yukon and Yukon XL. The distinctive Denali models are instantly identifiable by their signature chrome grille and unique exterior appointments, including exclusive high-intensity discharge headlamps.

Additional exterior features include:
- New inlaid doors fit into the body side openings instead of over the top of the body, significantly reducing wind noise and contributing to improved aerodynamics
- Laminated windshield and front door glass to enhance quietness

- New family of 18-, 20- and 22-inch wheels, including standard 20-inch wheels on Denali.

Inside, the all-new 2015 Yukon's precisely crafted interior features a quiet cabin, authentic materials and premium infotainment choices. Examples include soft-touch instrument panel, console and door panel materials with live stitching and purposeful use of ambient lighting in functional areas, including first- and second-row foot wells and the center console. All models have a standard Bose sound system, seats with dual-firmness foam and an ambient air vent designed to enhance comfort for front-seat passengers.

Denali models feature active noise cancelation technology to make the interior quieter.

There are more storage options in the new Yukon lineup, including a compartmentalized center console that's large enough to store a laptop or iPad and has provisions for hanging file folders and other organizational features, especially for customers whose vehicle also serves as a rolling office.

More capable, more comfortable
The 2015 Yukon lineup delivers greater capability and greater refinement through new and enhanced chassis and suspension systems. A fully boxed frame – composed of more than 75 percent high-strength steel – supports a quiet and controlled ride. New shear-style body mounts attached to the frame significantly improve stiffness and contribute to the Yukon's smooth ride.

Compared with previous models, the driving experience of the new SUVs is further enhanced with:
- Wider rear track that contributes to a more planted stance
- Wheels that are a half-inch wider, reducing tire flex for improved cornering performance
- New, electric variable-assist power steering system enhances fuel economy and tailors steering assist to vehicle speed

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 – SAE-certified 420 horsepower (313 kW) and 460 lb-ft of torque (623 Nm).

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.

The new Yukon family will be built at GM's Arlington, Texas assembly plant, and scheduled to begin arriving at GMC dealerships in the first quarter of 2014.
