The standard engine is a 290-hp 4.8-liter V8. Tahoe 4WD models come standard with a 320-hp 5.3-liter V8 that features GM's Displacement on Demand technology that quiets four cylinders in many normal driving situations. A version of this engine also can run on either E85 ethanol-blended fuel as well as on regular unleaded gasoline.
The LS ($33,115) is the base model and should account for about 15 percent of sales. Standard equipment includes dual-zone air conditioning, cloth seating for five people, with power adjustment for the driver's seat, 17-inch wheels, a tire-pressure monitoring system, four-wheel disc brakes with anti-lock technology, StabiliTrak stability control designed to keep the vehicle on the driver's intended course and to reduce the possibility of a rollover when the vehicle leaves that course. Also included as standard equipment are a steering column that tilts, intermittent windshield wipers, power locks and mirrors as well as windows, side assist steps, an eight-speaker audio system with CD player and a year of OnStar service.
The LT ($34,865) is expected to be the most popular version, accounting for 65 percent to 70 percent of sales. To simplify ordering, the LT offers three variations for the 2007 model year. The LT-1 package adds a cargo shade, floor console, color-keyed door handles, heated exterior mirrors, fog lamps, custom bucket front seats, steering wheel-mounted audio and cruise controls and a sound system with rear audio controls with headphone jacks. The LT-2 adds dual-zone automatic climate control, power-adjustable pedals, a remote starter system, leather seats, an audio system with a six-CD changer and MP3 capability, Ultrasonic rear parking assist and a universal garage door opener. The LT-3 adds power folding rearview mirrors with turn signals, side-curtain airbags, 12-way power driver's seat with memory, power-adjustable front passenger seat, Bose Premium 9-speak audio with subwoofer and XM Satellite Radio. Based on choices made by current Tahoe owners when they bought their vehicles, Chevrolet expects the LT-3 to be the most popular version.
The LTZ ($43,140) comes with 20-inch wheels, Autoride air-assisted rear suspension, heated windshield washer system, heated second-row seats with a power release to enhance access to the cargo area or standard third-row seat, a locking rear differential, power rear liftgate and rain-sensing front wipers.
Optional equipment for the Tahoe includes an auxiliary transmission cooler, engine block heater, navigation system, rear-seat video entertainment system, rear-view camera system, sunroof and a third-row that seats two people in buckets or three people on a bench. Accessories include specially styled wheels, brush guards for the grille and tail lamps, roof rack cross rails, a cargo tray, deep-ribbed rubber floor mats and hitch-mounted bike and ski carriers.
