GMC has unveiled the 2015 Sierra Denali which boasts a number of minor enhancements.

Looking virtually identical to last year's model, the 2015 Sierra Denali is the first full-size truck to be equipped with a magnetic ride control system that promises to provide "more precise body motion control that correlates with a more refined ride while maintaining payload and trailering capability."

Additional changes are limited but the truck also features Siri Eyes Free compatibility and a Text Messaging Alerts feature which can read incoming text messages aloud. There's also a new OnStar 4G LTE system with a built-in Wi-Fi hotspot that comes with a three-month / 3GB data trial.

Engine options carryover and include a 5.3-liter V8 with 355 bhp (265 kW) and 383 lb-ft (518 Nm) of torque as well as an optional 6.2-liter V8 that develops 420 bhp (313 kW) and 460 lb-ft (623 Nm) of torque.
