The '07 Suburban is based on GM's new, full-size SUV architecture, which features sleek exterior styling, a sharper, more precise driving feel, more power with improved fuel economy, increased interior refinement and improved quietness. Suburban rides on a 130-inch (3,302 mm) wheelbase, which supports generous passenger and cargo capability, while enabling a smooth ride. It also offers a host of new and enhanced safety features, including available head curtain side air bags and standard StabiliTrak stability control system with new rollover mitigation technology. Suburban is offered in LS, LT and LTZ models, with 2WD and 4WD, as well as 1500 and heavy-duty 2500 series. Suburban 1500 models come standard with an efficient 5.3L V-8 with Active Fuel Management fuel-saving technology. Later, a new, all-aluminum 6.0L V-8 with Active Fuel Management and variable valve timing (VVT) will be available. A 6.0L engine with an iron cylinder block is offered on 2500 models. Several available engines run on E85, a renewable fuel made of 85 percent ethyl alcohol (ethanol) and 15 percent gasoline. Suburban 1500 offers up to 8,200 pounds (3,720 kg) of towing capability (2WD models), when properly equipped; Suburban 2500 can tow up to 9,700 pounds (4,400 kg). Returning to Suburban is the popular Z71 Off Road appearance package. This optional package takes the vehicle's aggressive look to the next level, with larger recovery hook openings, larger, more prominent fog lamps and specific grille texture and platinum chrome grille trim. Eighteen-inch wheels and on-road/off-road tires also are part of the package. Suburban also offers power articulated running boards. They blend smoothly with the vehicle's design, but automatically move downward and outward when the doors are opened, providing a lower step-in height. Superior safety The '07 Suburban offers security in the form of a 360-degree perimeter safety system of occupant protection and crash avoidance technologies. New features include roof-mounted head curtain side air bags with rollover protection for all seating rows and front-seat safety belt pretensioners that are linked to the vehicle's sensing system to provide segment-exclusive deployment in rear-end crashes. These features are integrated into a stronger vehicle structure that is also designed for improved compatibility with other vehicles. The roof-mounted 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 segment-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 segment's first rollover indication sensors, which is located on the vehicle's center tunnel in the occupant compartment. The sensor monitors the vehicle's accelerations 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 air bags 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 steering. 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 with a smaller vehicle. Additional safety features include: Standard StabiliTrak stability control system with rollover mitigation technology Standard dual-stage driver's front air bag Standard dual-stage outboard-front passenger air bag with Passenger Sensing System Available roof-mounted head curtain side air bags for all three seating rows Standard front seat safety belt pretensioners with rear impact deployment capability Standard tire pressure monitoring system Available rain-sensing wiper system Available Ultrasonic Rear Parking Assist that can detect certain stationary objects in the rearward path of the vehicle and send an audible warning sound and display via three LEDs on the right D-pillar Available rear-view camera system designed to provide the driver with a view of people or objects in the rearward path of the vehicle Standard pull-up/push-down power window switches All models come with 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. New structure Suburban is built on GM's new full-size SUV platform, which incorporates features such as a new, fully boxed frame, coil-over-shock front suspension, rack-and-pinion steering and an all-new, premium interior system that bolster the vehicle's comfort, quality and capability. Wider front and rear tracks enhance handling and lower the center of gravity for a more confident road feel. Extensive attention to detail was paid to ensure a quiet driving experience. It centers on a new, stiffer frame, which reduces vibrations transmitted to the passenger cabin. The strength and accuracy of the fully boxed frame also enables more precise mounting and tuning of chassis and suspension components, which also help reduce vibration. Even the tires on the large, 17-inch standard and 20-inch available wheels were designed to reduce noise. Also, a sleeker shape, thanks to improved aerodynamics, streamlined exterior mirrors and roof rack, more steeply raked windshield and tighter body gap tolerances, assures a quiet ride. Suburban's quietness and smoothness is complemented by the Autoride suspension system, which is standard on LTZ. This segment-exclusive bi-state, real-time damping system provides an extremely refined ride with greatly reduced body motion. The system consists of a semi-active, two-position damping control system that responds in real time to road and driving conditions, based on body and wheel motion sensors. Design details Suburban wears the new face of Chevrolet, with a large Chevy gold bowtie, centered on a twin-port horizontal grille. The body-colored grille surround is inset with an argent texture mesh. Fog lamps and headlamps feature jewel-like optics. The lower fascia, incorporating the front license plate holder and integrated tow hooks, is aggressively styled with a skid plate look that enhances Suburban's rugged, off-road appearance. Suburban's front end styling reflects its capability. It includes the fast-rake windshield; a bulging power dome hood; a prominent new fender design with integrated wheel flares; a distinctive new grille and headlamps; and a full-wrap fascia. The wraparound fascia, which eliminates the conventional bumper-to-body gap, is one of the numerous attributes that gives the Suburban a more refined look. It also enhances aerodynamics. There also is a new family of 17-inch and 20-inch wheels. Seventeen-inch wheels and tires are standard, with 20-inch factory-installed wheels available (standard on LTZ). The larger wheels fill Suburban's wheel houses, giving the vehicle a confident stance. Suburban is offered in nine exterior colors: Greystone Metallic, Dark Blue Metallic, Sport Red Metallic, Bermuda Blue Metallic, Black, Summit White, Gold Mist Metallic, Amber Bronze Metallic and Silver Birch Metallic. Refined interior and thoughtful convenience The interior represents significant new levels of refinement, comfort, quality and convenience. The roomier interior is airy, thanks to a lower instrument panel and deeper windshield that improve outward visibility. Passenger space also is increased, including more shoulder space for rear passengers, which is packaged with the available roof-mounted head curtain side air bags with rollover protection for all seating rows. Behind the first-row seats, Suburban offers 137.4 cubic feet (3,890.6 liters) of cargo room. Suburban's seats are designed to provide more comfort, additional passenger-carrying flexibility, and easier entry/egress. Door pillar-mounted first- and second-row three-point safety belts facilitate the slimmer designs (second-row, center position uses an SUV-typical three-point belt-to-seat design). Seat comfort has been further improved with firmer foams, including more aggressive bolsters. The front-row seats have one-inch more aft travel than previous models. Second-row seats provide 0.4 inch (10 mm) more legroom and knee room. Their seatback angle is adjusted an additional two degrees rearward for extra comfort. Refinements throughout Suburban's spacious interior create an environment that exudes quality and precision. A two-tone color scheme is executed with new, softer and low-gloss materials for the instrument panel and other trim pieces. Also, there are almost no exposed metal hardware or latches, as all models feature enclosing close outs around the seat bottoms and door sill trim plates. Accessibility and capability are enhanced with features that include a unique power-release fold-and-tumble second-row seat and a third-row seat that also is easily removable. New comfort features include increased seat travel and seatback angles and an upgraded HVAC system. Storage capability is improved with the segment's largest center console storage bin, a larger glove box and additional new storage compartments. Suburban's interior features include: Power-release fold-and-tumble second-row seat Remote vehicle starting system First- and second-row heated seats Ultrasonic Rear Parking Assist Rearview camera system Touch-screen navigation system DVD rear-seat entertainment system with larger, eight-inch screen and enhanced features. Suburban also features an impressive new audio/navigation lineup, which provides quality entertainment and information. A new family of CD/MP3-compatible radios leads the audio lineup, with an enhanced DVD entertainment system that includes a larger, 8-inch screen (with in-dash loading). A new touch-screen navigation radio is available and incorporates the view monitor for the available rear-camera system. Enhanced efficiency Standard in Suburban 1500 models is an iron-block Vortec 5.3L V-8 with 320 horsepower (239 kW)* and 340 lb.-ft. of torque (461 Nm)*, which offers Active Fuel Management fuel-saving technology. Active Fuel Management technology seamlessly switches between eight- and four-cylinder power to save fuel. Two versions of the Vortec 5.3L Gen IV V-8 including a 310-horsepower (231 kW) aluminum-block version that is standard in 4WD models are compatible with E85 ethanol-based fuel, an alternative to gasoline. The engines can run on any combination of gasoline and/or E85 fuel. Available for fall production on 1500 models is a powerful, new all-aluminum 6.0L V-8 with variable valve timing, as well as Active Fuel Management displacement on demand technology. The engine 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 dual-equal cam phaser the industry's first application of VVT on a mass-produced V-8 cam-in-block engine. The unique dual-equal phaser adjusts the camshaft timing at the same rate for both the intake and exhaust valves. A Hydra-Matic 4L70 electronically controlled four-speed automatic transmission is paired with the engine. Heavy-duty Suburban 2500 models offer a 6.0L V-8. It features an iron cylinder block and is rated at 352 horsepower (263 kW)* and 383 lb.-ft. of torque (519 Nm). It is matched with a robust Hydra-Matic 4L80 four-speed automatic transmission. Contributing to Suburban's more efficient performance is improved aerodynamics. A more steeply raked windshield and smoother roofline improve airflow over the vehicle, while a dditional contributors to efficiency include a lower, wider front air dam, tighter tolerances and gaps between the fascias, lamps and grille openings, and improved front-end sealing that nearly eliminates air leak paths. These features all contribute to enhanced fuel economy and improved driving quietness, compared with previous models. |
