Overview & Reviews

GMC is a division of General Motors that focuses on producing SUVs, trucks and vans. Though GMC's vehicles are mechanically similar to related Chevrolet products, they are typically differentiated by unique features, trim levels and minor styling tweaks. The automaker's full-size pickups and SUVs are the most compelling offerings in its lineup; in many cases, its products in these categories are class-leading.

The marque's roots lie in the Rapid Motor Vehicle Company, a truck manufacturer that was founded by Max Grabowski in 1902. The outfit was purchased by General Motors in 1909 with the intention of having it serve as a division dedicated to building tough and capable trucks. The brand came to be known as GMC Truck; early models include the T16 and T20. Most of the manufacturer's trucks were very utilitarian in nature and functioned as dump trucks, fire trucks and military vehicles. GMC Truck's 3/4-ton Model 16 saw duty in World War I, serving mostly as a battlefield ambulance.

Sales continued to climb in the 1920s. After switching to a six-cylinder Buick-built motor, GMC Truck's 1- and 2-ton trucks earned the distinction of being the fastest in their classes. By the '30s, the line had grown to include everything from half-ton pickups to 10-ton trucks and buses. New models included the popular 1936 Suburban, which was essentially a truck-based station wagon that paired a truck's utility with a car's creature comforts.

World War II was a time of expansion for GMC Truck, thanks to its acquisition of Yellow Truck & Coach. Once again, the automaker's vehicles were tapped for wartime duty. New models like the Jimmy and the DUKW (nicknamed the Duck) were widely used by American troops.

Postwar, GMC Truck models became more consumer-oriented, and many were revamped to offer styling that more closely resembled passenger cars. The 1950s and '60s witnessed an upswing in sales, thanks to the popularity of recreational vehicles like GMC-based motor homes and pickup campers. The Jimmy name was revived and assigned to the brand's first ever sport-utility vehicle in 1970. That decade and the next saw a continued rise in the brand's popularity. The early '90s saw the brief appearance of the Syclone and Typhoon. The former was a small street pickup that burned up the asphalt with its turbocharged V6 and all-wheel drive. The latter was essentially a two-door SUV based on the same platform. Either one of these oddball speedsters could rip through a quarter-mile in around 14 seconds flat, making them among the quickest vehicles ever offered by General Motors. Also, by this time, GMC Truck had trimmed its moniker; the brand is now known simply as GMC.

In the past few decades, GM has consolidated its products and GMC's trucks have become less individualistic as a result. Today, most of GMC's vehicles are virtually identical to those sold by Chevrolet. The main differences lie in minor features and design tweaks that give GMC's offerings a more upscale image.

  2015 Sierra HD diesel - 2015 GMC Sierra 2500HD
  By Jon - November 1 - 2:14 am

  So, yes. The SD card reader is pretty much useless. But all of the storage is amazing. The 6.6 is amazing along with the Allison transmission. Im getting 17 in town and 20-21 on highway. Towing my tractor around is a breeze almost forget its behind me. I did read the other reviews and the gap at the tailgate is real, and it does let a lot of dust in, However you can buy a seal kit for it. The safety features are cool. With the vibrating seats, lane departure detection, and back up camera, if you crash and its your fault. It is actually your fault. bottom line Ive owned a lot of vehicles, other than a minivan which I havent owned but have been in and was amazed at the comfort and room this is the best and most useful vehicle you can get.

  EXCELLENT CHOICE IN CROSSOVERS - 2009 GMC Acadia
  By krishnameee - October 31 - 9:05 pm

  I have been throughly stunned at the ride of this crossover. Pricey but worth the money. GM needs to look at some extras to keep the customers happy like seat memory standard on SLTs. Turning radius and fuel efficiency was very good. I topped at 27 MPG at 59 MPH freeway. I have driven about 400 miles so far and very satisfied

  No wonder GM went bankrupt - 2009 GMC Acadia
  By Dan - October 31 - 2:37 pm

  Weve had the car for about a year and a half. Put plenty of miles on it. It breaks every month. Its been back to the dealer 16 times since weve had it. Leaks, trans problems, failed water pump, electrical problems, brake problems, rear hatch lifters, etc. Whenever I see someone who has put all 10s in their edmunds review, I immediately discount those reviews as someone who is congratulating themselves for a purchase, rather than reviewing a car. The amount of lemon law lawsuits over the Acadia is stunning. Too bad actually, because this could have been a great car, but unfortunately, GM has too many problems as a company to take care of their customers.

  2008 Denali AWD - 2008 GMC Yukon
  By lgb - October 30 - 7:12 pm

  We first test drove the yukon SLT to replace our 2005 Denali. We never used the rear DVD player or Navigation in our 2005 so we thought we would down grade to the regular Yukon. NOT! Had to go back to the Denali series because the regular yukon didnt compare to the comfort we were used too. So we purchased a 2008 Denali.

  Great truck at a great price - 2008 GMC Sierra 1500
  By OleMissDispatcher - October 29 - 11:53 pm

  Have owned truck for almost 600 miles and really enjoy the truck. It has 5.3 V8 with the Flex Fuel Management. City driving is ok, highway is a lot better. For a base model, it came fully loaded with all power options, CD, cruise, fog lights, chrome bumpers, towing package, XM, and OnStar (which I think XM and OnStar were standard). Truck can ride rough over unkept streets, but still a lot better than my old Chevrolet Tracker. Air and heat are great. Cant wait to try the 4x4!

  stop replacing ball joints!!! - 2001 GMC Jimmy
  By MK - October 29 - 1:44 pm

  Seeing all the other reviews and my own experience (GM Tech) DO NOT replace ball joints on this vehilce. GM specs allow for ALOT of play" or movement and 95% of independent shops will tell you you need ball joints replaced when you do not. If you think you need them or are told by a mechanic, take veh to a GM dealership and have them check and compare to allowed specifications. Most Jimmys and Blazers can go 150,000 miles + without needing replacement of ball joints!

  Brake Problems - 2008 GMC Canyon
  By ken Almonrode - October 29 - 12:39 pm

  The day I picked it up the head lights would not shut off and brake pedal went almost to the floor. the Dealer fixed the head lights and was told the brakes were ok they are all like that. Back to the dealer for wipers that turned on by their self and low tire light coming on for on reason. Took vehicle to a none dealer service station were they trued the rear drums and solved the brake problem.

  Exactly What I Wanted - 2010 GMC Acadia
  By Very Pleased - October 28 - 1:12 pm

  I’m very pleased thus far. Easy to park, feels to be the right size overall. I have only 900 miles on it so far, took one long trip (700 miles) up & down desert mountain Interstates at 75-80MPH and averaged 22MPG. On a local freeway, mostly level at 70-75 I saw a high of 26MPG but mostly 24+ so as they say “Your mileage may vary.” Engine & transmission work very well. If you nail the throttle getting on the freeway and let the engine/trans do their thing, there’s plenty of power to get on the freeway that may result in a big ticket. The dash & controls are laid out very well. I have found no flaws in the paint or trim fit. I am very pleased & will update when I get more miles on it.

  Yukon XL - 2005 GMC Yukon XL
  By hdteacher - October 28 - 9:20 am

  This is the fourth Yukon I have owned. This is the first XL however. I love the extra room I have and the XL is just as easy to handle as the shorter version. The heated front seats make early morning travel a pleasure! The electronic folding mirrors make going through a car wash so easy. I plan to purchase a new 2007 XL in about 6-12 months. This is the best large SUV on the market. The trade in valus doesnt depreciate like the other SUVs.
