Using EPA carbon footprint figures, SAE peak horsepower and torque, and published engine displacement, we evaluated the popular engines available in every half-ton truck to determine which engines offer the best compromise between power and environmental efficiency.



Dodge's "gas-guzzling" 5.7 HEMI came out on top because it produces significantly less carbon annually than engines with similar size and power.

In an odd note, the Chevy Silverado Hybrid 6.0 produces the exact same amount of carbon annually that Dodge's HEMI produces, yet it offers drastically less power. Chevy's own 5.3L, based largely on 1960's technology, produces less carbon than the 6.0 Hybrid while delivering similar performance.

Since the Chevy 5.3 is nearly as powerful as the Hybrid 6.0, and produces less carbon annually, what exactly is the point of the Hybrid? Yet another example of marketing wining out over science.
