Significant changes are in store for the 2009 Chevrolet Suburban, including a more fuel-efficient six-speed automatic transmission on all 1500 models, choice of two optional rearview cameras, standard 50/50-split third-row bench and Bluetooth connectivity. The navigation system now comes with real-time traffic capability, and the LTZ trim level gets 12-way heated/cooled leather seats and enhanced exterior trim. Available as two-wheel or four-wheel drive, the Suburban 1500 is equipped with an E85-capable 5.3L V8 that pumps out 310 hp and 335 lb-ft of torque, while a 6.0L V8 that packs 366 hp and 376 lb-ft of torque is optional, and both engines are paired to the new six-speed automatic transmission. Suburban 2500 trims come with a 6.0L V8 rated at 352 hp and 382 lb-ft of torque attached to a six-speed automatic. The Suburban 2500 can tow up to 9,600 pounds, seat up to nine passengers and provide up to 137.4 cubic feet of cargo space. Fuel economy ranges 14-16 mpg in combined driving, depending on the trim and the engine, while towing or carrying a heavy load can lower the mpg. Chevrolet Suburban safety features highlight antilock disc brakes, stability control, OnStar and three-row side curtain airbag system with a rollover sensor.
