Introducing the All-New 2020 GMC Sierra HD

The 2020 GMC Sierra HD lineup is coming soon to Ron Smith Buick GMC in Merced

The GMC Sierra HD is back and better than ever. With the all-new model year comes powerful and innovative updates. Check out what is sure to make the 2020 GMC Sierra HD a standout in the heavy-duty pickup market.


One of the most impressive updates is the incredible power. An all-new Allison® 10-speed automatic transmission is a segment-first, and, when paired with the 6.6-liter Duramax turbo-diesel engine, will deliver impressive power and capability. This engine is set to deliver a jaw-dropping 445 horsepower and 910 lb-ft of torque.


The 2020 Sierra HD will boast a segment-first Rear Camera Mirror, which offers a better picture of the road behind you. With the advanced ProGrade™ Trailering System, you can have up to 15 different camera views behind the wheel, including a segment-first transparent trailer view that allows you to see through the trailer.

More Versatile

You’ll be able to find the perfect Sierra for you, especially with the addition of the AT4 model for the 2020 year. The Sierra AT4 Heavy Duty can take on off-road situations with more ease than other Sierras and still offers 2500 and 3500 variations. The six-function MultiProTM tailgate, offering ample storage and loading versatility, is a world-first and comes available on every trim level (and standard on three).

The 2020 GMC Sierra HD will be available later this year at Ron Smith Buick GMC. If you’ve got big needs — in terms of capability and luxury — you’re not going to want to miss this.
