I only saw "estimated" power ratings for the 6.2. :dunno:

Good to see GM retake the "most powerful..." back from Ford's 6.2.

One of the salesmen that I deal with at the local GMC dealer texted me this afternoon to let me know they have a '14 in route. I may have to take it for a spin when it hits the lot.

A 5.3L EcoTec3 V-8 is standard for the 2014 Sierra Denali. It produces 355 horsepower and offers better EPA-estimated fuel economy (23 mpg highway on 2WD models) than any V-8 or turbocharged V-6 pickup on the market.
This takes some steam out of the marketing for the 3.5 Ecoboost since MPG is one of the benefits touted by Ford. The Ecoboost still has more torque and marginally more hp than the EcoTec 5.3 though.


Sierra Denali will be available with two option packages, including a Z71 Off-Road Package (4WD only) with monotube Rancho shocks, Hill Descent Control and transfer case shield, and a Driver Alert Package that includes Lane Departure Warning, Forward Collision Alert and patented Safety Alert Seat Technology.

The one thing I couldn't stand about the Denali's that we have owned in the past (Yukon & Sierra) is that we had to get AWD since 4WD wasn't an option previous in the half ton Denali's. I'll be all over another one if this is the case.

Surprising that the 5.3 is the standard engine in the Denali instead of the usual 6.2 but good to see they're offering a real 4x4 system on it.

Idk who to blame. If you can afford a $60k truck you probably don't care about the improved mileage of the 5.3 over the 6.2. Idk who would buy such a truck and not get the big engine.

I'm just saying if you care about mileage are you probably aren't dropping $60k+ on a tarted up pickup. Maintenance costs should be identical between the 5.3 and 6.2 :dunno:
