Thanks to info posted on the GMC US build and price configurator, we now know that the Sierra AT4 will be offered with the upcoming 3.0-liter diesel engine.
Under the list of options for the AT4, the build and price tool lists the “available 3.0L Duramax Turbo Diesel engine with 10-speed automatic transmission (late availability).”
Based on newly uncovered info on the AT4’s brother truck, the Chevy Silverado Trail Boss, on the Chevy Canada build and price tool, it looks like the Trail Boss does not get the diesel option.
The AT4, like Trail Boss, comes with a two-inch lift, unique wheels wrapped in Goodyear Wrangler Duratrac tires, Rancho shocks, skid plates and the G80 rear locking differential.
The AT4 can also be had with the 6.2-liter V8, yet another engine option that has been held back from Silverado Trail Boss so far. Pricing for the diesel option still isn’t included, and when you do add it to a truck on the GMC Canada configurator, a message advises you to “see dealer for pricing,” so we don’t know how much these trucks will cost yet.
In the US, the AT4 starts at about $51,300 with the 5.3-liter V8 as a double cab standard bed, while adding the big V8 drives the price up to just over $53,890. In Canada, the AT4 starts at about $55,500, while the 6.2-liter brings it up to $58,390.
The diesel will likely end up being an even more expensive option, which is why it’s being kept in the GMC brand, but it would be nice to see the Silverado Trail Boss expands its lineup to include at least the new turbocharged 2.7-liter four-cylinder. Although the 6.2 would be better….just saying Chevrolet.
