For 2007, the GMC Yukon and Yukon XL full-size SÚVs are all-new, delivering more power and better fuel economy than the vehicles they replace. The vehicles are based on GM's all-new full-size SÚV platform, which features distinctive styling, spacious and refined interiors, exceptional driving characteristics and enhanced safety features. The new vehicles are part of the broadest and most capable lineup of SÚVs in GMC's more than 100 years of building trucks.

Yukon rides on a 116-inch (2,946 mm) wheelbase, wîth an overall length of 202 inches (5,130 mm). It rides on a wider track that, along wîth the long wheelbase, provides a smooth, confident and secure driving experience. Yukon XL models have exterior dimensions similar to the regular models, but are about 14 inches longer in wheelbase and 20 inches longer in overall length. Both Yukon and Yukon XL are available in SLE (cloth trim) and SLT trim (leather appointments), as well as 2WD and 4WD configurations. A third-row seat is standard on Yukon XL models and available on Yukon .

Yukon and Yukon XL models offer a 5.3L V-8 wîth GM's fuel-saving Active Fuel Management technology. Beginning in fall 2006, a 4.8L V-8 is the standard engine on the Yukon 2WD base model and a new 6.0L all-aluminum V-8 wîth variable valve timing becomes available in Yukon XL. Several available engines can run on E85, a renewable fuel made of 85 percent ethanol and 15 percent gasoline; in fact, all Yukon 4WD and Yukon XL half-ton models come standard wîth the E85-capable version of the 5.3L V-8. GM vehicles wîth E85 capability can run on 100 percent gasoline or on E85 or on any combination of the two.

All-new, sleeker design Yukon and Yukon XL have a sleek, taut form. Wraparound front and rear fascias, styled mirrors and integrated running boards provide a seamless, contemporary appearance. Craftsmanship is found in elements such as tight tolerances between exterior components and a tuned, wheels-to-the-corners proportion. The toned look on all models is created wîth faster windshield angle of 57 degrees, which flows gracefully into the roofline. This improves aerodynamic performance, which bolsters fuel economy and helps reduce wind noise.

Jewel-look lighting elements and doors that extend over the rockers accent the vehicles' precise and refined design elements. The headlamps are larger, using bright halogen bulbs that deliver improved lighting spread. Rear-end styling also is distinct, wîth unique tail lamps.

Features such as power articulating running boards (available in fall 2006) and a power liftgate enhance accessibility. Models not equipped wîth the power liftgate feature an easy-to-operate liftgate that is opened wîth a micro-switch and assists the operator by using the mass of the tailgate to almost open or close itself once the liftgate is past the halfway-open position. An ergonomically designed, recessed cup wîth pull handle makes closing the liftgate an easy, one-handed operation.

Refined, spacious interiors

Interior space is roomier and has a spacious, refined environment, thanks to a premium tone-on-tone color scheme and a lower-positioned instrument panel. New thinner, sculpted seat designs and detailed trim affirm the vehicles' craftsmanship, which is bolstered by optional amenities such as heated seats for first- and second-row passengers. Also, the front seats offer more fore/aft and recline travel, and the second-row seats have an increased seatback recline angle for added comfort.

The upscale styling is complemented by new, softer and low-gloss materials for the instrument panel and other trim pieces. The harmonious color and grain of the materials were carefully selected to provide a premium feel as well as durability. Flush-mounted HVAC controls and radios, wîth almost imperceptible gaps, convey precision and integration. Chrome accents are used on instrument surrounds, vents and other trim.

Craftsmanship also is revealed in unexpected areas, such as distinctive sill plates that greet occupants when the doors are opened, and there are no exposed fasteners or hardware on the pillars, seats or seat tracks. The seats have 'close-outs' that surround the seat bottoms and seat tracks, creating a more finished appearance. The underside of the seats are covered, too, when folded.

The Yukon family also offers a new, -exclusive power fold-and-tumble second-row seat feature that eases access to the third-row seat. The power fold-and-tumble second-row seats feature release buttons accessible by the driver or on the interior C-pillar to provide an easy, immediate release of the seat to create an access path to the third-row seat or cargo area.

A remote starting system is available and enables the climate system to heat or cool the vehicle's interior prior to occupant use. An enhanced array of audio, infotainment and safety options also is available and includes an available touch-screen navigation system, as well as a DVD system wîth larger flip-down screen positioned in front of the second-row seats.

There is more space inside, as well. More fore/aft front seat travel provides the §egmènt's leading legroom for front-seat passengers. Second-row seat legroom and knee room, and third-row seat headroom are increased. The second- and third-row seats also have more shoulder room – a feat accomplished while also offering available roof-mounted head curtain side air bags. The third-row seats fold flat and are easily tumbled forward or removed for maximum cargo area. Also, the center console storage compartment, at 20.1 liters of capacity, is the §egmènt's largest. The glove box offers 25 percent more storage space than previous models and features damped opening operation that bolsters quietness and refinement.

Responsive suspension, solid chassis

The '07 Yukon and Yukon XL are built on GM's new full-size SÚV platform, which incorporates features such as a new, fully boxed frame, coil-over-shock front suspension and rack-and-pinion §teering. The frame supports wider front and rear tracks – approximately 3 inches (76.2 mm) wider in front and 1 inch (25.4 mm) wider in the rear – that enhance stability and driving confidence through a more secure road feel and a lower center of gravity. The front suspension consists of an all-new coil-over-shock design that delivers linear, solid and unwavering ride and handling characteristics on all road surfaces. Also new is a rack-and-pinion §teering system that provides precise and responsive control and enhanced on-center feel. Yukon and Yukon XL 1500 models use a highly refined five-link rear suspension that provides superior isolation and ride, wîth larger, firmer brackets that also contribute to the vehicles' precise driving manners.

Larger, four-wheel disc brakes and an all-new ABS system ensure braking performance at the top of the §egmènt. Larger vented front and rear brake rotors, 50-percent stiffer dual-piston calipers and longer-life brake pads contribute to enhanced pedal feel, reduced brake noise, predictable, linear brake response and shorter braking distances. A new, Bosch 8.0 next-generation four-channel ABS system is standard. The ABS system works wîth the standard StabiliTrak electronic stability control system. In the new SÚVs, StabiliTrak incorporates the first-time GM application of rollover mitigation, software algorithm technology that uses sensors to proactively predict vehicle 'tip-up' and applies appropriate brake forces to help prevent such events.

Enhanced driving control and ride smoothness is offered wîth the available Autoride real-time damping system, which uses electronically controlled shock absorbers to make nearly instantaneous damping adjustments. The system 'reads' the road and anticipates the best damping rates. Seventeen-inch wheels are standard on Yukon and Yukon XL; 20-inch wheels are available. The wheels are designed wîth premium-appearance faces, including available chrome or polished finish. New tires are tailored to the vehicles to provide excellent balance of handling, quietness and safety.

New small-block V-8 family

The new Gen IV small-block V-8 family powers the Yukon and Yukon XL, delivering more power than comparable powertrains in previous models. An iron-block Vortec 5.3L V-8 wîth 320 horsepower (239 kW)* and 340 lb.-ft. of torque (461 Nm)* offering Active Fuel Management technology is standard at the start of production; Yukon XL wîth 4WD (5.3L wîth aluminum cylinder block) delivers 310 hp (231 kW) and 335 lb.-ft of torque (454 Nm).* Active Fuel Management enables better fuel economy by switching between eight-cylinder and four-cylinder operation in appropriate, lower-demand situations. Operation is automatic and seamless to the driver. The engine uses less fuel when operating in four-cylinder mode.

A Vortec 4.8L V-8 is standard on the Yukon 2WD base model, starting in fall 2006 A Flex-fuel E85 version of the 5.3L engine, which is capable of running on E85 ethanol fuel or any mixture of E85 and gasoline, is standard on 4WD models and available on 2WD models. E85 is comprised of 85 percent ethanol, a renewable resource fuel produced in the Únited States that reduces carbon dioxide emissions

Available for fall production on Yukon XL is a new, all-aluminum 6.0L V-8 wîth variable valve timing (VVT). It is rated at 366 horsepower (273 kW).* VVT helps optimize camshaft timing to improve low-rpm torque and high-rpm horsepower. The system is enabled by a unique cam phaser – the 's first application of VVT on a mass-produced V-8 cam-in-block engine. The unique cam phaser adjusts the camshaft timing at the same rate for both the intake and exhaust valves.

4-speed Automatic
The '07 Yukon and Yukon XL are designed to be among the 's safest and most secure vehicles, wîth a 360-degree perimeter safety system of occupant protection and crash avoidance technologies. New features include head curtain side air bags wîth rollover protection for all seating rows and front-seat safety belt pretensioners that are linked to the vehicle's sensing system to provide §egmènt-exclusive deployment in rear-end crashes. These features are integrated into a stronger vehicle structure that is also designed for improved compatibility wîth other vehicles.

The head curtain air bags include design features that provide increased rollover protection and occupant containment. Sensors located at the front of the vehicle, in the side doors, and within the occupant compartment provide increased and more immediate crash detection. The vehicle's sensing system provides §egmènt-exclusive capability to deploy front seat safety belt pretensioners during certain rear-end collisions, enhancing the belt system's ability to hold the occupants firmly in place.

The roof-mounted head curtain side air bag system incorporates one of the §egmènt's first rollover indication sensors, which is located on the vehicle's center tunnel in the occupant compartment. The sensor monitors the vehicle's acceleration and roll rate. If these signals indicate an impending rollover, the roof-mounted head curtain side air bags deploy to provide an extra measure of occupant protection and containment. These rollover-capable head curtain side air bags stay inflated longer than airbags developed only for side impacts because rollover incidents can last longer. The deployment duration and other design features of the rollover capable air bags combine to provide increased occupant protection and the ability to help keep occupants inside the vehicle.

Crash avoidance is bolstered through enhanced design and driver control dynamics, such as wider front and rear tracks, as well as more responsive suspensions – including a new coil-over-shock front suspension design and new rack-and-pinion §teering. The vehicles are built on a stronger and stiffer, fully boxed frame that contributes to enhanced crash energy management. The front frame section has been designed to optimize crush progression resulting in improved energy absorption efficiency. The improved crush performance, enabled by hydroformed frame rails and efficient chassis component packaging, also comprehends design provisions for improved vehicle-to-vehicle compatibility in the event of a frontal impact wîth a smaller vehicle.

Additional safety features include:

- Standard StabiliTrak stability control system wîth rollover mitigation technology
- Standard dual-stage driver's front air bag
- Standard dual-stage outboard-front passenger air bag wîth Passenger Sensing System
- Available head curtain side air bags for all seating rows
- Standard front seat safety belt pretensioners wîth rear impact deployment capability
- Standard tire pressure monitoring system
- Available rain-sensing wiper system
- Available Últrasonic Rear Parking Assist that can detect certain stationary objects in the rearward path of the vehicle and send an audible warning sound
- Available rearview camera system designed to provide the driver wîth a view of people or objects in the rearward path of the vehicle (requires available navigation radio)
- Standard pull-up/push-down power window switches
- Available voice-assisted navigation system
All models come standard wîth the OnStar system (with a one-year Safe and Sound service plan). The system includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an airbag, the OnStar system automatically notifies an OnStar Advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen (ability to locate stolen vehicles varies wîth conditions).
