Compare the 2021 Chevy Silverado vs GMC Sierra | Which is Better?

2021 Chevrolet Silverado

If you’re in the market for a new truck, chances are you’ve heard about the Chevy Silverado and the GMC Sierra. These trucks share a popular following for various reasons. Comparing them can be complicated with all the confusing features and benefits offered. That’s why we’ve created this head-to-head comparison guide to help you decide which truck works best for you. Let’s have a closer look at the 2021 Chevy Silverado vs. the GMC Sierra.

Exterior Style

The Chevy Silverado comes in five trim levels plus several special editions, giving you plenty of options to match your particular style. The Silverado rolls on 18-inch wheels standard but offers several different types up to 22 inches. A power open and close multi-function tailgate and 2-inch factory suspension lift are attractive features for truck lovers. Chevy offers several off-road packages that include the factory lift plus signature black alloy wheels and Goodyear Wrangler DuraTrac Mud Terrain tires. 

Chevy special editions like the RST Rally feature Rally stripes, emblems, and cool black accents that turn heads along the boulevard. An LT Trail Boss Midnight edition gets blacked-out treatments all around the exterior, and high-intensity discharge headlights light up the night.

GMC offers the Sierra in five trims yet lacks the special edition lineup from Chevy. The Sierra’s exterior features include their signature C-shaped LED headlights and corner steps integrated corner in the rear bumper. The Sierra has a multi-function tailgate as well but doesn’t have the power open/close functionality. The AT4 trim offers off-road options and equipment that put it close to the LTZ and Trail Boss Chevy models. 

Overall, the Chevy Silverado has an appealing exterior that looks good on the highway and even better when you leave the pavement behind. The nod here goes to the Silverado because of the variety of trims and that power tailgate that the Sierra doesn’t have.

Interior Comfort

Inside the Silverado, you’ll find more space than ever before. Front passengers love the best-in-class head and legroom, while the rear passengers enjoy plenty of leg and shoulder room with the new layout from Chevy. Storage compartments located within the rear seatbacks are another segment-first from Chevy. The premium cloth on the lower trims delivers durable comfort. Upscale leather upholstery on the higher trims adds a refined style. Heated and ventilated seats are options on the lower trims and standard on the upper models.

Apple CarPlay and Android Auto support allow you to sync your smartphones for hands-free operation with intuitive voice commands. The Silverado also turns into a 4G LTE Wi-Fi hot spot that connects up to 10 devices and boasts a range of up to 50 feet.

The Sierra offers similar interior amenities like available leather seating with heating and ventilation options. Storage compartments under the rear seat provide useful spots to hide your gear. The Sierra offers Apple CarPlay and Android Auto compatibility as well but lacks the hot spot feature.

A slight edge goes to the Silverado for its more comprehensive interior amenities over a broader selection of trims.

Powerful Performance

Chevy offers five engine options on the Silverado lineup. Chevy has a 4.3-liter EcoTec3 V-6 engine and a six-speed automatic transmission. This powertrain delivers 285 horsepower and 305 pound-feet of torque. The 2.7-liter turbocharged engine with start/stop technology pairs with an eight-speed automatic transmission to put out 310 horsepower and 348 pound-feet of torque.

Chevy offers a 5.3-liter EcoTec3 V-8 with dynamic fuel management mates to an eight or 10-speed automatic transmission depending on the model. This powertrain gives you 355 horsepower and 383 pound-feet of torque. Chevy’s 6.2-liter V-8 engine gets paired to a 10-speed automatic transmission, delivering an impressive 420 horsepower and 460 pound-feet of torque.

The Duramax 3.0-liter turbo-diesel engine delivers the perfect blend of power and efficiency. Also mated to the 10-speed automatic transmission, this powerful combination puts out 277 horsepower and 460 pound-feet of torque. 

When properly equipped, the Silverado can tow up to 13,300 pounds. Plus, the Silverado comes with advanced towing capabilities like a 15-camera video system and in-vehicle trailer tech that monitors tire pressure, lights, and more for multiple trailer configurations. Trailer sway control, trailer theft alert, auto grade braking, and hill start assist systems help you tow confidently with the Silverado.

Both Chevrolet and GMC are owned by General Motors, so it’s no surprise they offer the same five-engine lineup in the Sierra as they do in the Silverado. The power numbers remain the same along with the towing capacities. Both trucks finish tied in this category.

Safety Features

The Silverado has various driver-assist systems available that use a combination of advanced radar and optical sensors to monitor the Silverado’s surroundings. Systems include a forward collision alert that scans the road ahead for potential hazards, alerting you when detected. Should you fail to react, the automatic emergency braking system engages to help lessen a possible impact. 

Adaptive cruise control keeps your Silverado at a preset speed and distance while in traffic. The system slows you down as the traffic slows, even to a complete stop. When the way ahead clears, the system returns you to your presets. Lane change alert with side blind zone alert helps you change lanes with confidence. Sensors alert you when vehicles enter your blind spots so you can change lanes with confidence.

The Sierra 1500 also features a suite of available driver-assist systems. These systems use similar technology to deliver the same results, a safer driving experience. The Sierra and Silverado are even in this category as well.

When comparing both trucks, they match up well with power, performance, and safety. The edge goes to the Silverado for its stylish and functional exterior and comfortable interior.
