After a complete redesign in 2014 that helped it earn a Consumers Guide Automotive Best Buy award and Kelley Blue Book’s 5-Year Cost to Own award, the Sierra Light Duty adds an all-new eight-speed automatic transmission to its powertrain roster, enhancing efficiency and refinement while maintaining capability. It’s included on models equipped with the EcoTec3 6.2L V-8 engine.
Sierra’s new eight-speed automatic helps the pickup retain its 5,443 kg (12,000-pound) maximum trailering rating under newly adapted SAE J2807 Recommended Practices. Additionally, the entire lineup is available with a number of features engineered for serious towing, which features a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning, enhanced cooling and an integrated trailer brake controller to optimize capability and comfort when trailering.
Magnetic ride control is a new, exclusive standard feature for the distinctive Sierra Denali. Based on the real-time damping system that’s standard on the all-new, 2015 GMC Yukon Denali, it delivers more precise body motion control by “reading” the road every millisecond and changing damping in just five milliseconds.
Sierra Denali is the only full-size truck to offer magnetic ride control; and along with the available 6.2L V-8 and new eight-speed automatic transmission, solidifies its position as the most refined, technically advanced truck on the market.
