The 2009 GMC Yukon Hybrid blends interior and exterior features from the other four Yukon trims around its 6-liter, hybrid V8 (332 hp, 367 lb-ft of torque) that is mated to an electronically controlled, hybrid-specific, four-speed automatic transmission that gets 21 city/22 highway mpg. The Hybrid comes with a heavy-duty locking rear differential, aluminized stainless steel muffler and tailpipe, heavy duty trailering equipment, StabiliTrak traction control, and GMC’s Premium Smooth Ride Package. Its maximum payload is 1,830 pounds, and maximum towing capacity is 6,200 pounds.
Other exterior features include high-end mirrors (power-adjustable, power-folding, integrated turn signals, driver’s auto-dimming, ground illumination, and curb tilt), halogen headlamps, rear wiper, rear liftglass, and the unique Hybrid front and rear fascia.
The Hybrid’s interior features a rear parking-assist system with LED camera display, tri-zone air conditioning, Bluetooth, cruise control, auto-dimming rearview mirror, five auxiliary 12-volt outlets, a 115-volt, three-prong outlet in the rear quarter trim, driver information center, power programmable locks, consoles with rear audio and HVAC controls, and power windows with driver’s express. The AM/FM/CD/MP3-compatible stereo with TheftLock, voice recognition, XM radio, and XM NavTraffic comes with a nine-speaker Bose surround sound system (with a subwoofer in the center console). The front bucket seats are 6-way power adjustable for the driver and passenger, the second row is a 60/40-split leather bench, and the third row is a 50/50-split, removable, three-passenger bench.
The 2009 GMC Yukon Hybrid 4WD comes with the same interior, exterior, and drivetrain features as the Yukon Hybrid and is equipped with an electronic Autotrac transfer case with rotary controls for the four-wheel-drive system. The Hybrid 4WD gets 20 city/20 highway mpg (compared to 21/22 for the 2WD Hybrid), has a 1,773-pound maximum payload, and a 6,000-pound maximum towing capacity.
The 2009 GMC Yukon SLE1 serves as the base trim for the Yukon model. The SLE1 has a unique drivetrain, with a 295-hp, 305 lb-ft/torque, 4.8-liter V8 paired with a four-speed automatic transmission (all other trims offer a more-powerful engine and a six-speed transmission) that gets 14 city/20 highway mpg. The SLE1's performance is enhanced with a premium suspension, tow/haul mode selector, and GMC’s StabiliTrak stability control system. The SLE1 has a maximum towing capacity of 4,800 pounds and a maximum payload of 1,830 pounds.
The interior of the SLE1 features dual-zone air conditioning, cruise control, power locks and windows, cloth seats, a 40/20/40 split for the front bench, a 60/40 split for the second-row bench, a driver information center, color-keyed carpeting, and steering-wheel-mounted audio controls for the AM/FM stereo, which features an MP3-compatible CD player and XM Radio. The exterior features body-color, power, heated and manual fold-away mirrors; halogen headlamps; a roof-mounted luggage rack with black side rails; body-color assist steps; and 17-inch bright aluminum wheels.
The 2009 GMC Yukon SLE1 4WD shares interior and exterior features with the rear-wheel-drive SLE1, but makes a major drivetrain change. Like all the Yukon 4WD trims, the SLE1 4WD is powered by a 5.3-liter V8 SFI FlexFuel engine, which is capable of running on unleaded or up to 85 percent ethanol gas, produces 320 horsepower and 340 lb-ft of torque, and is paired with a six-speed automatic transmission with overdrive to get 14 city/20 highway mpg. The 4WD system adds 200 pounds to the vehicle's gross vehicle weight (7,300 pounds), subtracts just 57 pounds from its maximum payload capacity (down to 1,773 pounds), and pushes its maximum towing capacity from the 7,400 pounds of the rear-wheel-drive SLE1 to 8,200 pounds.
The 2009 GMC Yukon SLE2 makes its biggest upgrades from the SLE1 in the powertrain, featuring a 5.3-liter, 320-horsepower V8 paired with a six-speed automatic transmission with overdrive that gets 14 city/20 highway mpg. The SLE2 adds to or replaces the exterior features of the SLE1, offering halogen foglamps, luggage rack center rails, and two frame-mounted recovery hooks in the front. Interior upgrades and additions include rear HVAC and audio system controls with two headphone jacks, front buckets with a six-way power-adjustable seat for the driver, outboard adjustable head restraints, a floor console with storage bin, and rear storage pockets.
The 2009 GMC Yukon SLE2 4WD shares interior and exterior features with the rear-wheel-drive SLE2, but adds four-wheel drive for improved handling in difficult conditions. Like all the Yukon 4WD trims, the SLE2 comes with a 5.3-liter, 320-horsepower V8 SFI FlexFuel engine that can run on unleaded gasoline or 85 percent ethanol. This V8 is paired with a six-speed automatic transmission with overdrive and gets 14 city/20 highway mpg, the same mileage as the rear-wheel-drive trims. The SLE2 4WD is 200 pounds heavier than its rear-wheel-drive counterpart, weighing in at 7,300 pounds. Its maximum payload is 53 pounds less than the RWD version, coming in at 1,773 pounds. But its maximum towing capacity is 8,200 pounds, a significant jump from the RWD trim's 7,400.
If you want more interior technology in your SUV, the 2009 GMC Yukon SLT1 is a good place to start looking. The SLT1 shares a drivetrain, exterior, and interior features with the SLE2 and then makes the following significant gadget upgrades: air-conditioning with tri-zone automatic climate control, AM/FM/MP3-compatible stereo with 6-CD in-dash CD changer, nine-speaker Bose sound system with subwoofer in the center console, power-adjustable pedals, remote start, rear parking assist system, auto-dimming rearview mirror, universal home remote, and a 50/50 split in the third-row bench seat for added cargo space.
If all the added technology of the SLT1 appeals to you (that includes a Bose sound system, power-adjustable pedals, remote start, a rear parking assist system, and more), but you also drive in lots of bad weather or off-road muck, the 2009 GMC Yukon SLT1 4WD might be the trim for you. The SLT1 4WD gets the 5.3-liter, 320-hp V8 SFI FlexFuel engine, which can run on unleaded or 85 percent ethanol and gets 14 city/20 highway mpg, pretty good numbers for this size SUV. The four-wheel-drive system makes the SLT1 4WD about 200 pounds heavier (its gross vehicle weight is 7,300 pounds) and ups the maximum towing capacity to 8,200 pounds (the rear-wheel-drive version tows 7,400).
The 2009 GMC Yukon SLT2 is at the top of its model lineup. But it’s worthwhile to note that the SLT2’s MSRP is only $785 more than the SLT1's, so there aren’t too many upgrades here. The interior gets leather-appointed front buckets with 10-way power-adjustable seats for the driver and front passenger, which also get power lumbar control, heated seat cushions and seatbacks, and two-position driver memory. The exterior upgrades focus on the mirrors, which are body-color, heated, power-adjustable, power-folding, and come with integrated turn signals, ground illumination, and curb tilt. The SLT2 does have more available options as well, including power-retractable assist steps, a heated washer fluid system, and a power liftgate. The drivetrain is the same as the SLT1's.
The 2009 GMC Yukon SLT2 4WD shares interior and exterior features with the SLT2 (including 10-way power heated seats for the driver and passenger, a nine-speaker Bose sound system, power-folding and heated exterior mirrors, and tri-zone air-conditioning). Like all the Yukon four-wheel-drive trims, it has a 5.3-liter, 320-horsepower V8 SFI FlexFuel engine, which can run on unleaded gasoline or 85 percent ethanol and gets 14 city/20 highway mpg. The 4WD trims are also about 200 pounds heavier than their rear-wheel-drive counterparts (the gross vehicle weight for the SLT2 4WD is 7,300 pounds) and can tow a significant amount more as well - the SLT2 4WD has a maximum towing capacity of 8,200 pounds.
