Edmunds' Expert Review
by the Edmunds Experts
Pros
- Powerful drivetrains, roomy interior, numerous available amenities.
Cons
- Spotty build quality, cheap interior materials.
What’s new
The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and optional multifunction, fold-away mirrors. On the inside, GMC has added new seats, a more comprehensive driver information center, a redesigned instrument panel and optional dual-zone climate control and satellite steering wheel controls. On the hardware side, the standard 6.0-liter V8 gets electronic throttle control as well as the ability to run exclusively on Compressed Natural Gas (CNG) or a mix of CNG and gasoline. Other upgrades include an improved Insta-Trac part-time four-wheel drive system for reduced service costs, a more efficient starter for the 8.1-liter V8 and a revised headlight switch that allows drivers to turn off the daytime running lamps.
Edmunds says
With its powerful engine lineup and revised interiors, the heavy-duty Sierra makes a strong case for itself against the competition.

Still smiling...
brian0105, 08/04/2003
2003 GMC Sierra 2500HD 4dr Crew Cab SLE 4WD SB (6.0L 8cyl 4A)
I researched long and hard when
deciding on the $$ for the
Duramax/Allison combo. Man am I
pleased! It pulls my travel trailer
like it wasn't even there. MPG has
been better than my previous Firebird.
Comfort is much better than I expected
for a 3/4 ton. Looks? Man, you can't
beat the Fire Red color! Don't know
what it might take to wipe this smile
off my face!

Fuel Economy
Chevy Man, 03/03/2010
2003 GMC Sierra 2500HD 4dr Crew Cab SLE 4WD SB (6.0L 8cyl 4A)
I've had my 2500HD for just under a year now and I LOVE it. The only problem I really have is its fuel economy. I average around 14 mpg, but where it lacks fuel economy it makes up for it in power. I haul around a skidsteer on a 14 ft open trailer. The skidsteer weighs more then my truck but still no problems pulling it. The fuel economy doesn't really change weather your hauling or not. … I just purchased an SLR performance chip that should do the trick. This truck is perfect for anyone with the money to pay for gas.

Excellent Duramax Diesel!

Don't want to spend to much time here,
but if your thinking about buying this
vehicle w/ this motor, all I would say
is "do it". It awesome!
