The tried and tested GMC recently rolled out a facelifted version of Sierra. Sierra was considered as a cousin to Silverado but with the arrival of the new face-lift, Sierra has now embarked on a different route.

Not affected by the number of recalls pickup trucks are plagued with, Sierra has always been the first choice of truckheads as stats show that this truck is the least recalled truck in the competition.

We Recommend

We recommend picking up the SLE trim since it adds a host of creature comforts that are bound to make life easy for the occupants.

Moreover, it is certainly worth the extra money you'd pay for it.

The engine duties on the GMC Sierra 1500 are handled by a 4.3L 6-cylinder motor mated to a 6-speed auto gearbox. The base engine is good for producing 285 hp and 305 lb-ft of torque. The figures are modest, to say the least, but they sure do make the truck feel lethargic on open roads.

Ride and Handling of the 2020 GMC Sierra 1500

The GMC Sierra 1500 is a big vehicle and it behaves like one too. The truck is at its best when cruising on a highway at a moderate speed, something it does like the back of its hand. It is not to perform cornering at crazy speeds, in the mind which is the reason why it shouldn't be done in the first place. The truck does behave erratically over uneven surfaces and the issue is worsened when low profile tires are installed.

Braking of the 2020 GMC Sierra 1500

The 2020 GMC Sierra 1500 features a set of 13.0-inch brake rotors in the front and a set of 13/6 inch rotors in the rear. Even with its substantial curb weight, the truck is able to stop from 60 mph to a standstill in an impressive 134 feet.

2020 Chevy Silverado 1500 vs 2020 GMC Sierra 1500

The Chevy Silverado 1500 is a cousin of the Sierra 1500 truck. They share the same powertrain, chassis and even design elements to an extent. The Silverado, on one hand, features a lot of cosmetic look good exterior components while the GMC Sierra takes a more rugged approach. Hence, this one is totally up to the preference of the customer since they are virtually the same trucks.

2020 Chevrolet Silverado

2020 Ford F-150 vs 2020 GMC Sierra 1500

The Ford F-150 just like the GMC Sierra 1500 takes a very hands-on approach to work. It is fine as a work truck but that's all it is. The exterior is boring while the interior is borderline tacky. The GMC Sierra 1500 features a much more comfortable interior which makes it a better truck in our honest opinion.
