The all-new 2015 Chevrolet Suburban debuts in early 2014, offering more functionality, greater refinement, new safety features and an increased range of advanced technologies.

A more-efficient, direct-injected EcoTec3 powertrain coupled with improved aerodynamics help offer greater estimated highway fuel economy based on GM testing while preserving overall performance and capability.

The all-new 2015 Suburban represents the 80th anniversary and 12th generation of the original SUV. This generation is designed for today's active families needing space for everyone and everything. Suburban continues to offer legendary roominess, unmatched functionality, connectivity and first-class amenities.

The exterior of the 2015 Suburban is refined and precisely sculpted. Not a single exterior sheet metal panel or lighting element is shared with Chevy's full-size pickups. Projector-beam headlamps flank the Chevrolet-signature dual-port grille -- chrome on all trims -- and sweep into the front fenders. High-intensity discharge headlamps and light-emitting diode daytime running lamps are included on the up level LTZ model.

Suburban's standard 5.3L V-8 comes with 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.

Improved engine mounts, electronic throttle control, adaptive exhaust systems, improved aerodynamics and other technologies help the engines operate in four-cylinder mode more often with Active Fuel Management, further increasing efficiency. The engine is mated to a Hydra-Matic 6L80 six-speed automatic transmission, featuring TapShift control, Tow/Haul mode and Auto Grade Braking.
