Silverado V6 Vs. V8? – What Are The Differences?

The Chevy Silverado is available in two types of engine options. There is the V6 which boasts a six-cylinder engine, and the V8, with eight cylinders. Apart from this, these two trucks have some more significant differences that I will be discussing below.

Torque and horsepower

The Silverado V6 outputs a maximum horsepower of 285 HP at 5300 rpm and of torque at 3900 rpm.

On the other hand, the Silverado V8 delivers between 355 HP at 5600 rpm and 420 HP of maximum horsepower. The torque ranges between 383 lb.-ft for the 5.3 L EcoTec3 V8 and 460 lb.-ft. for the 6.2L EcoTec3 V8. Because of the V8’s high horsepower and torque, it boasts better acceleration than its V6 counterpart.

Maximum towing capacity

The V6 boasts a maximum towing weight of up to 7 900 lbs. On the other hand, the V8 can tow up to 13,300 lbs. depending on the engine type.

For example, the 5.3L EcoTec3 V8 can comfortably tow up to 11,200 lbs. This is because, unlike the V6, it features the max trailering package. However, not all models have this add-on. You can tell if your Silverado has a max trailering package by checking for the NHT RPO code inside the glovebox. So, overall, the V8 boasts better towing capacity than the V6.

Fuel consumption

The V6 is considered more fuel efficient than the Silverado V8 because of its small engine. It uses about 15 gallons of fuel per mile in the city and 20 MPG on the highway.

The Chevy Silverado V8’s fuel consumption in the city is 12.5 MPG and 10.8 MPG on the highway. Therefore, during the same journey, you will use less fuel with a V6 than with a V8.

Engine capacity and transmission

A Silverado V6 truck features a Flex-fuel (FFV) engine type with a capacity of 4.3L. In addition, it utilizes a six-speed shiftable automatic transmission.

On the other hand, the V8 comes in two engine types. You can choose between the 5.3L EcoTec3 and the 6.2L EcoTec3 engine. Further, this truck boasts an 8-speed automatic transmission.

The V8 retakes the win here because, thanks to its bigger engine size, it produces more power than the V6.


Generally, vehicles with longer wheelbases provide better ride quality than their counterparts with short wheelbases.

Now, the Silverado V6 features a 153-inch wheelbase, while that of the V8 is 147.4 inches only. So, you get to enjoy a comfortable and stable ride with the V6. However, the V8’s shorter wheelbase makes it an excellent choice for off-roading.
