The 2008 Chevrolet Avalanche gains standard curtain side airbags on all models. This reconfigurable pickup truck is essentially a crew-cab version of Chevrolet's Suburban SUV with a folding midgate separating the cab from the cargo bed. Lowering the midgate extends the bed to 8.2 ft from 5.3. Avalanche seats up to six and comes in LS, LT, and LTZ trims. Each is available with rear-wheel drive or full-time 4-wheel drive that can be left engaged on dry pavement and includes a low-range gear for off-roading. Standard on 2WD Avalanches is a 320-hp 5.3-liter V8 engine. 4WD models get a 310-hp version of the same engine. The latter is capable of running on E85 ethanol-blended fuel. Optional on LT and LTZ models is a 366-hp 6.0-liter V8. All engines have GM's Active Fuel Management cylinder deactivation, and they team with a 4-speed automatic transmission. Maximum towing capacity is 8200 lb. Available safety features include ABS, traction control, antiskid system, and curtain side airbags. GM's Autoride load-leveling suspension is standard on LTZs, optional on LTs. Options include a navigation system and DVD entertainment.
