While an electric vehicle like the Tesla Cybertruck may be more fuel-efficient than the 2020 GMC Sierra 1500

its fuel efficiency could surprise you. The greatest approach to get excellent fuel efficiency 

Additionally, the Sierra's fuel efficiency exceeded expectations when its diesel engine was put through its paces.

When the Sierra's 3.0-liter V6 diesel engine was put through official testing,

the EPA obtained fuel efficiency readings of around 23 MPG in the city, 30 MPG on the highway, and 26 MPG combined.

However, those statistics apply to the Sierra's two-wheel drive variant, which isn't a favourite among truck enthusiasts.

When using the identical V6 diesel engine, the Sierra's four-wheel drive system had somewhat poorer fuel efficiency. 

. According to the EPA, it achieved a combined MPG of 24, 26 MPG on the highway, and 22 MPG in the city. 

Overall, those are only little reductions in fuel economy, but since four-wheel drive is such a common 

Results obtained by real users of these diesel trucks differed slightly from those obtained by the EPA.

For Ram, news sites actually reported a lower fuel economy than anticipated, despite the fact that the Ram 1500's

In the instance of the Ram 1500, the difference in fuel economy was around 4 M

The V6 diesel engine in the Sierra and its sibling, the Silverado, is less potent than the diesel in the Ram 1500,

Trucks, these diesel engines actually achieved greater fuel efficiency than predicted by the EPA.
