Chevy introduced a new special edition for the Tahoe and Suburban: the street-performance Rally Sport Truck, or RST. The Chevrolet Tahoe RST will also be available with a new Performance Package that includes a 420-hp, 6.2L V-8 engine; Magnetic Ride Control with performance calibration; and an all-new Hydra-Matic 10L80 10-speed automatic transmission. "Chevrolet has continually invested in Tahoe and Suburban, developing models with varying combinations of capability, technology and performance to meet the needs of different customers," said Sandor Piszar, Chevrolet Truck Marketing director. "The RST is designed for customers who want a street performance look without sacrificing capability or refinement, along with the option of increased performance as well."
The LT1 engine is available with a standard six-speed manual transmission - with new Active Rev Match technology that "blips" the throttle for perfectly timed downshifts - or the Hydra-Matic 8L90 paddle-shift eight-speed automatic. Each engine has been carefully tuned for a distinctive performance sound. All 2.0L turbo models feature active noise cancellation, which uses sound waves to cancel unwanted cabin noise. Models equipped with the available Bose audio system also feature engine sound enhancement, which amplifies the native sounds of the 2.0L turbo engine - and can be disabled based on the driver preference. Both the 3.6L V-6 and 6.2L V-8 feature mechanical sound enhancers - resonators that direct induction noise from the engine bay into the cabin. Both engines are available with a dual-mode exhaust, which features electronically controlled valves that bypass the mufflers under acceleration, delivering improved performance and greater sound levels. With the dual-mode exhaust, drivers can personalize the exhaust sound, from a "stealth" mode to the most aggressive "track" mode.
The engine also features Chevrolet first application of Exhaust Gas Heat Recovery, or EGHR, technology, which uses exhaust heat to warm the engine and cabin. EGHR improves engine warm up and ensures consistent fuel economy performance in cold weather. Additional fuel economy benefits come from Exhaust Gas Recirculation, or EGR. An 80-cell, 1.5 kWh lithium-ion battery pack provides electric power to the hybrid system. It can power the Malibu Hybrid up to 55 miles per hour (88 km/h) on electricity alone. The gasoline-powered engine automatically comes on at higher speeds and high loads to provide additional power. In addition to the drive unit, the Malibu Hybrid also shares the 2016 Volt blended regenerative braking system, which provides maximum kinetic energy recovery during braking to be stored into the battery system to help maintain charge, and drive unit power electronics. An all-new, Ecotec 1.5L turbo is the standard engine in the 2016 Chevrolet Malibu, offering a GM-estimated 37 mpg on the highway. It is part of a new global family of small-displacement gas engines designed with greater power density to deliver confident performance with excellent efficiency.
