2008 GMC Yukon Review
The 2008 GMC Yukon adds an available gas/electric hybrid model. This report covers the Yukon and half-ton Yukon XL 1500. These large SUVs share their basic designs with the Chevrolet Tahoe and premium Cadillac Escalade. All were redesigned for the 2007 model year. Compared to the Yukon, XL models are about 14 inches longer in wheelbase, 20 inches longer overall, and have nearly 30 cu ft more cargo volume. Yukon and Yukon XL come in SLE, SLT, and luxury Denali models. All are available with rear-wheel drive. SLE and SLT have optional full-time 4-wheel drive that can be left engaged on dry pavement and includes a low-range gear for off-roading. Denalis are available with all-wheel drive without low-range gearing. Standard on 2WD Yukon SLE is a 295-hp 4.8-liter V8 engine. All remaining Yukons and XLs have a 320-hp 5.3-liter V8. Optional on XL is a 366-hp 6.0-liter V8. Yukon Hybrids have a 320-hp 6.0-liter V8 that pairs with an electric motor. These models can run on one or both of their power sources, depending on driving demand and require no plug-in charging. The 5.3- and 6.0-liter engines have GM's Active Fuel Management cylinder deactivation. All these engines use an automatic transmission. Conventional gas models have a 4-speed. Hybrids use a continuously variable transmission (CVT). Yukon Denalis have a 380-hp 6.2-liter V8, 6-speed automatic transmission, and specific interior and exterior trim. Maximum towing capacity is 8200 lb for regular-length models, 8100 lb for XL. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. A power tailgate, power running boards, navigation system, and DVD entertainment are among available features on the 2008 GMC Yukon.
Competition
Consumer Guide Automotive places each vehicle into one of 18 classes based on size, price, and market position. Large SUVs are traditionally workhorse seven-plus passenger wagons with brawny truck-type chassis, ample towing ability, lots of cargo space, and generally poor fuel economy. These vehicles offer towing and payload ratings similar to large pickup trucks.
Our Best Buys include Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and Ford Expedition. We have no Recommended picks in this class for 2008.
New or significantly redesigned models include the Toyota Sequoia. The Chevrolet Tahoe and GMC Yukon add a gas/electric hybrid model for 2008.

News
Though just redesigned, Yukons and their Chevrolet siblings are expected to add a hybrid powertrain option for 2008. The result of a GM-DaimlerChrysler-BMW collaboration, this new "two-mode" system is said to use twin electric motors and a 300-volt battery pack to assist a 5.3 V8 with GM's Active Fuel Management. It allows low-speed driving on either power source, and promises better overall fuel economy than conventional powertrains. Rival Dodge's midsize Durango SUV will offer a similar hybrid option in the '07 or '08 model years.
Further out, General Motors says it may offer a 330-hp diesel V8 for its largest SUVs by model-year 2010. GM is cagey about details for now, but says this new diesel will be a 32-valve dual-overhead-cam design--and clean enough for sale in all 50 states. GM projects a Yukon so equipped would get around 28 mpg in city driving vs. 21 for a comparable gas-engine model.

Consumer Guide® Road Test Ratings
Acceleration
Yukons are muscular off the line and in highway passing/merging with the 5.3-liter V8. Denali's 6.2 V8 feels stronger overall. The transmissions provide crisp, timely shifts, with the Denali's automatic having shift lever buttons for manual operation. We have not yet tested a Yukon Hybrid, but a similar rear-drive Chevrolet Tahoe Hybrid accelerates from a stop and passes much like a conventional model. A faint surge is felt and heard when the vehicle shifts between electric and gasoline operation.

Fuel Economy
In Consumer Guide testing, we've averaged the following: 16.7 mpg for a 2WD SLE, 14.4-14.8 for 4WD SLT, and 13.5-15.5 in Denali. A similar test Tahoe Hybrid averaged 22.8 mpg, outstanding for the class. GMC recommends regular-grade gas for SLE and SLT, premium for Denali. The 5.3 V8 can use E85 ethanol fuel.

Ride Quality
Yukons with 17-inch tires have car-like comfort over bumps, though they suffer some floaty motions over dips and swells. GM's Autoride load-leveling suspension quells some float but doesn't add demonstrably to ride comfort. Impact harshness over sharp bumps is exaggerated by the short sidewalls of the available 20-inch tires. Long-wheelbase XL models are slightly more comfortable regardless of tire choice. The Hybrid's low rolling resistance tires cause the ride to become more stiff. It's never harsh, though.

Steering/Handling/Braking
Steering has light effort that benefits around-town maneuverability, but it can feel overassisted at highway speeds--a sensation that seems to be exaggerated slightly with the 20-inch tires. Despite being tall and heavy, Yukons suffer relatively little noseplow and body lean in turns, though you would never mistake these SUVs for sport sedans. Our testers are divided on whether versions with Autoride feel any more confident in changes of direction. Brakes offer no-drama stopping power, solid pedal feel.

Quietness
Impressive for a large SUV. Road noise is well muted. The only evident wind rush comes from around outside mirrors. Though intended to be a more luxurious vehicle, the Denali's 6.2 V8 sounds louder and less refined during acceleration than lesser models' 5.3 V8. The Hybrid is nearly silent at ignition and at rest. A subtle electrical whirring noise is heard during acceleration from a stop and while decelerating.

Controls
All gauges are large, but some testers find the markings too indistinct for best legibility. Yukon's optional navigation system absorbs, but doesn't complicate, audio functions. The Hybrid's navigation screen features a helpful energy flow display that indicates when the vehicle is in gas V8 mode, complete electric mode, or electric-assisted gas 4-cylinder mode. Likewise, the efficiency gauge in the upper left corner of the instrument panel indicates the most efficient braking range to capture regenerative braking energy.

Details
The cabin has few soft-touch panels, but materials are generally solid to the touch and assembled with care to create a high-quality ambiance, even on SLE versions. Denalis get added dress-up touches.

Room/Comfort/Driver Seating (front)
Bench or buckets, the front seats are supportive. There's ample headroom and legroom, though the cramped center position on the bench should be for emergency use only. Available power-adjustable pedals aid driver positioning. Visibility is unobstructed by headrests or roof pillars, but the body's tall flanks block the driver's view of small nearby objects, making the optional rearview camera worth considering.

Room/Comfort (rear)
Adult-comfortable 2nd row. Available automatic-folding seats spring forward to ease access to the 3rd row, though passage is still tight, and the seats must be manually restored to their upright position. Low-to-floor 3rd-row cushion forces knees-up discomfort for anyone larger than toddler size.

Cargo Room
Spacious with two rows of seats. Second-row seats fold forward to expand cargo volume. There's no abundance of storage room behind the 3rd row in non-XL Yukons. The folded 3rd row seatbacks rest well above the load floor, complicating loading of large items. Those seats unlatch easily but are heavy and cumbersome to remove.

Value within Class
Yukon is pitched as an upscale alternative to Chevrolet's Tahoe, and the Denali is positioned just below Cadillac's Escalade. Despite having more power and luxury touches than Yukons, Denali doesn't deliver enough of either to justify its higher base prices and thirst for premium-grade gas. The Hybrid model's premium may seem sharp, but so are the fuel economy savings. This large SUV can achieve the fuel economy of a midsize car with no sacrifice in passenger or cargo capacity. The Hybrid, or a carefully optioned Yukon SLE and SLT are the Best Buy values in this GMC lineup.

Price note: SLT requires an Option Pkg.
Pricing Key: Retail prices listed with each report are set by the vehicle's
manufacturer. These figures appear on each car's federally mandated window sticker.
Most price lists also include dealer-invoice prices. Dealer-invoice prices are
what the dealer pays the manufacturer for the car and its factory-installed options.
The destination charge is not included in the suggested-retail or dealer-invoice price
and must be added to the cost of the vehicle. Car companies change prices frequently
throughout the year. If the prices published do not match those on the vehicle's
window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.
