Avalanche Vs. Silverado Differences?
These two trucks have several similar features, such as aluminum wheels, keyless entry, a three-year warranty, and cruise control. This makes it challenging to choose the best. So, below are features that tear them apart.
Engine, transmission, and horsepower
The Avalanche features a 5.3L V8 Flex-fuel engine with a 6-speed automatic transmission. This powerful engine delivers up to 320 horsepower at 5400 RPM and 335. lb-ft of torque at 4000 rpm.

Overall, you will find the Avalanche fast, but the Silverado is an excellent truck for towing, thanks to its maximum torque. However, unlike with the Avalanche, you may have to deal with 2014 Silverado transmission problems like a clogged converter.
Gas tank size
One of the notable differences between Avalanche vs. Silverado is their fuel tank size. The tank of Avalanche has a 31.5 gallons fuel capacity, while the Silverado has 24 gallons only.
With the Avalanche, you can drive for long distances without needing to refill your gas tank. But for Silverado, you have to make more stops to refuel.
Construction of the bed
The Avalanche boasts a 5 1/2-foot bed integrated into the body frame. Simply put, the Avalanche is a full-size, body-on-frame truck with a folding midgate. If you put the midgate down, you end up with an 8-foot-long bed.
On the other hand, the Silverado features an 8.20-foot-long bed, separate from the body frame. The Silverado also has a wide-width bed. For this reason, I recommend getting the Silverado if you must tow.
Fuel economy
The overall fuel economy rating of the Avalanche is 17 MPG, and 20 MPG for the Silverado. However, in the city, the Avalanche’s fuel consumption is rated at 15 MPG, and 19 MPG for the Silverado.

Seating capacity
The Avalanche is a 5-seater truck, while the Silverado has seating spaces for six people. And when it comes to the front seat legroom, the Silverado is the winner with a 44.53-inch size. The Avalanche only provides 41.1 inches of legroom.
However, the Avalanche is more spacious at the rear. This is because you get 39.1 inches of rear seat legroom. The Silverado boasts only 35.24 inches of back leg room.
Wheelbase
As for the Avalanche, it only has a wheelbase of 130 inches. This is simply the distance between the midpoints of the front and rear tires. On the other hand, the Silverado features a wheelbase of about 147.45 inches. Therefore, the Silverado offers better ride quality than Avalanche, which has a shorter wheelbase.
What Are The Common Problems of Avalanche and Silverado?
Some of the common problems you may experience with the Avalanche is the tailgate not opening. This happens when you want to increase the truck’s bed capacity. Another common problem is poor fuel economy.
With the Silverado, one common issue is faulty gas tank pressure sensors, leading to false fuel readings. Another common problem is a damaged oil pump, causing low oil pressure. When this issue occurs, you may get a warning in the form of P06DD code Chevy Silverado. However, most of these problems are common as your Silverado ages.
Which Is Better: Avalanche Vs Silverado?
Overall, the Chevy Avalanche and Silverado are high-performance trucks with impressive reliability. However, the Silverado offers better performance with its wide bed when it comes to towing. It also has the excellent horsepower, which you can increase by investing in performance spark plugs like the FLIBEN 8 PCS 41-962.
The Silverado is also a better choice than the Avalanche because it is more fuel efficient. It does not matter whether you are driving in the city or on the highway. Even better, it offers a better ride than the Avalanche, thanks to its long wheelbase.
