About 2015 Chevrolet Tahoe Chevrolet introduces the all-new 2015 Tahoe full-size SUV. It offers more functionality, greater refinement, new safety features and an increased range of advanced technologies. New functionality and technology features on the 2015 Chevy Tahoe include: Fold-flat second- and third-row seats that enhance cargo convenience, including an available power-folding feature; approximately 2 inches greater legroom for second-row passengers, along with easier entry/exit; available 8-inch color touchscreen radio with next-generation MyLink connectivity; up to six USB ports and six power outlets, including a 110-volt three-prong outlet; conversation mirror in the overhead console that provides a panoramic view of the rear seats; and keyless entry and push-button start. The 2015 Chevy Tahoe is engineered to deliver a quieter, more-controlled ride and improved steering and braking feel. It all starts on a stronger, fully boxed, perimeter frame, which supports payload and trailering capability that body-frame-integral crossovers and SUVs can't match. The driving experience is further enhanced with 18-inch wheels that are a half-inch wider, reducing tire flex for improved cornering performance. Twenty- and 22-inch wheels are available. Tahoe's 5.3L V-8 features state-of-the-art technologies, including direct injection, cylinder deactivation, continuously variable valve timing and an advanced combustion system, designed to make the most of power, torque and efficiency across a broad range of operating conditions. The engine is mated to a Hydra-Matic 6L80 six-speed automatic transmission, featuring TapShift control, Tow/Haul mode and Auto Grade Braking.
