The battle between the major truck manufacturers continues to heat up thanks to the proliferation of smaller, more efficient diesel engines in the half-ton truck range.

The latest to enter the fray is GM with its 3.0-liter Duramax unit, for which it announced pricing on Monday.

The new Duramax unit will find a home first in the 2020 Chevrolet Silverado 1500 and to get it, you're going to have to pay just as much as if you'd specced the 6.2-liter V8.

That means it's a $3,890 premium over the 2.7-liter turbo four-cylinder and just a hair under $2,500 more than the smaller 5.3-liter V8.

What are you sacrificing by going with the new inline-six cylinder diesel over the well-proven and decidedly excellent 6.2-liter V8 gasser?

To start with, it's rated at 277 horsepower and 460 foot-pounds of torque compared with 420 hp and an identical torque rating in the V8.
