Hey Everyone!

I'm making lemons out of this week. 11/8/14, an old woman in a HONDA CRV backed into my Beautiful, parked 1990 suburban 2500 7.4 liter (454) It was bad enough that she got HONDA on my CHEVY Suburban, but she also bent the front fender. Fortunately a bystander got her license plate or this hit-and-run grandma with bad taste in SUVs would have gotten away with her Suburban bashing. Now I've got her insurance company paying for repairs and the rental of a 2015 GMC YUKON for a week! I plan to thoroughly road test this new beast, so if you have any questions, post them here, and I'll try to answer them. So far, the avg MPG is just 14.6 - 15 which I thought would be higher. Anyywhoooo, I'll keep a log and post the good, bad, ugly and beautiful for anyone interested.
 
sorry to hear about your bad luck but at least you get to enjoy the new rental for awhile.
 
Sorry to hear that. We get attached to these things. I hope she got issued a ticket. People need to respect others no matter how old they are.
You answered one question; they don't get better mileage. Shame. What size engine? How much do they tow? How many cupholders? :p
 
dont forget mpg improves after a few thousand miles, how many on the rental?
 
Ok first the specific questions: This Yukon has 12,000 miles on it, so I don't know if that is enough to start getting better mileage. Towing capacity is 8300lbs trailer wt., 14000 GCWR(gross combo weight rating (for 4wd w/ 3.42 gears and trailer pk.), 5.3 liter EcoTec engine. 6 cup holders.
 
DAY 1

When I first saw the 2015 Suburban & Yukon, I have to admit that the exterior styling had me looking twice. I could really see myself in one of these. Then at last year’s auto show, I checked it out up close and experienced the interior. This just made me think about upgrading to a new vehicle even more. However, as an experienced driver, I know that looks are not everything and I was excited to get the opportunity for a week long test drive of the 2015 Yukon. This is a rental from Enterprise-rent-a-car and is a dark gray exterior with black leather interior. It is a beautiful example of the SLT trim level. It also has 4 wheel drive and a tow package.

The first thing you notice about these vehicles is the impressive exterior styling: they really get your attention and make you want to look inside. Once inside, the eyes immediately lock on the dashboard which is also impressive. The gauges are outstanding. In fact the whole interior is very well done and visually appealing.

When you get into the vehicle, you first notice very comfortable leather seats that adjust in every way possible. Then when looking through the windshield, my first thought was: Why does this seems so small for such a large vehicle? Well the windshield does feel a bit like you are looking through a telescope because the pillars are giant sized and directly in your line of sight. These pillars are filled with airbags for safety, but the sheer size as well as the unfortunate placement make them a distraction at best and reduce the driver’s visibility at worst. The windshield was a disappointment. The push button start was cool, but the real experience is driving.

This vehicle engine is rated at 355 HP and 383 lb-ft of torque, but is doesn’t feel like it. My 1990 with a 454 big block rated at 260 HP blows this away in acceleration. My truck will push you back in your seat immediately with it’s massive displacement and anolog gas pedal. With the EcoTec V8 there is a hesitancy in the gas pedal, the Yukon just doesn’t want to go fast quickly. You need to smash down the gas pedal and wait a few seconds just to get it going. Once going it is great but it really needs to be coaxed from the line.
 
I believe your vehicle produces 385 lb-ft of torque but being a much larger engine probably produces that number at a lower RPM. The 5.7 has to rev before it produces it's similar torque number.
 
OK first - correction - 12 (twelve) CUP holders.
Zora - you are correct. The Yukon makes 385 Hp at 4100 RPM, but almost always Shifts gears prior to hitting 4100 RPM - so you can't use it most of the time. You have a V8 and 14.6 MPG, but have to drive it like a Toyota Camry most of the time???? GM and Ford really need to give us more engine options, especially if they are continuing this EcoTec stuff. You can get a 6.2 ltr, but it is still an EcoTec. The new F150 has an aluminum V6 instead of a V8, and there is no way it is as good as this EcoTec V8 which is not a great choice in a truck. My good ole 454 wins this battle and proves there is no replacement for displacement.

However, The suspension on this new rig is remarkable. It is extremely stable, and comfortable. My "Cadillac ride" suburban is hard to beat, but this Yukon has it all. And to make things even better, the brakes are alson phenomenal.
 
OK, I'm bringing back the Yukon Monday and have had some time to compare it to my 1990 Suburban. I really worked to compare it to my current 1990 rig. I understand not everyone is partial to a 1990, so some of my views may be subjective. The 2015 wins some and the 1990 wins some as you can see below:

New 2015 Wins

EXTERIOR STYLING
The 2015 had my attention from the first picture and still does. However, the same is true for my 1990, so this is a tie.

GAS MILEAGE
The 2015 Yukon shows MPG at 16/23, but after over 2,000 miles, the mileage track in the vehicle showed 14.6. But that is still better than what my 7.4 liter 454 gets on it’s best day.

BRAKING
I cannot say enough about the braking on this vehicle! It is extremely stable and gives you a great amount of confidence.

SUSPENSION
I did not think a new vehicle could beat the “Cadillac ride” of my old Suburban. It seems that every newer vehicle I have driven has the same chopping ride that fells as though you are driving a light weight toy. This Yukon has a very smooth ride, that is also exceptionally stable, and hugs the road in a remarkable way. You could not feel more comfortable and safe with this suspension.

TRANSMISSION
This 6 speed transmission is outstanding. Smooth, strong, and quick shifts. It also has the Manual “auto stick” feature which lets you do the shifting without a clutch. This is a great feature that provides the benefit of controlling your HP and torque power band by maintaining a specific a RPM range. Since the EcoTec V8 makes 383HP at 4100 RPM, this gives you the ability to run in the 4100 RPM range, whereas, the automatic transmission would shift gears prior to reaching this RPM. Since the engine does not have great get up and go, the transmission really helps out. This SUV is a fantastic freeway cruiser with the current power train. It also takes hillsbetter than most anything out there.

ELECTRONICS AND TECHOLOGY
If you like this sort of thing, then it goes without saying the 2015 wins. It has tones of plugs, and I think you may be able to use a hair dryer in the back seat with that AC plug.


My Old 1990 Wins

ACCELERATION
The 2015 engine is rated at 355 HP and 383 lb-ft of torque, but is doesn’t feel like it. My 1990 with a 454 big block rated at 260 HP blowns this away in acceleration. There is a hesitancy in the gas pedal, the Yukon just doesn’t want to go fast quickly – it wants to second guess your intent. You need to smash down the gas pedal and wait a few seconds just to get it going. Fortunately the manual transmission option on the 6 speed automatic helps out a bit with this lack of power.

WINDSHIELD/BACK WINDOWS
Why does this seem so small for such a large vehicle? Well the windshield does feel a bit like you are looking through a tunnel because the pillars are giant sized and directly in your line of sight. These pillars are filled with airbags for safety, but the sheer size as well as the unfortunate placement make them a distraction at best and reduce the driver’s visibility at worst. The windshield was a disappointment. The same goes for the rear window. Not only does in not roll down, but it is TINY. Not only is visibility compromised, but when you open it, the opening is much smaller than the window itself. You can hardly fit anything through this window. The side rear windows are also tiny and dwarfed by huge pillars. These are so ridiculously massive that you must have the largest blind spot of any vehicle on the road today. Fortunately there is a blind spot sensor, because you definitely need it.

INTERIOR
This one is going to get some argument, but I have to go with my old suburban here. Leg room in the front seats and third row seat, visibility, driving comfort and functionality win the day here. My suburban’s center console and door panel do NOT cramp your leg room like the new version. Specifically, the door panel has a section for the power windows that cuts into your left leg right below the knee. The third row seat can be utilized by a grown man in my 1990 Suburban, but this is not possible in the 2015. I can see behind me through the back window and roll it down in my 1990. The 2015 rear window does not roll down, and has very limited visibility. The 2015 has the electronics and technology, but I don’t want those anyway. Even if I did, they are readily available to install in my 1990.

TAILGATE/LIFT GATE
My 1990 suburban has an actual TAILGATE, but the 2015 does not – it has a lift gate. There is nothing like sitting on this tailgate while TAILGATING at a college football game, or watching a drive-in movie. In fact, all the kids insist on hanging out on the tailgate of my old suburban even when their parents are driving the newer Suburban with the lift gate only.

Yes, the tailgate is heavy, and harder to open or lift, and no it doesn’t automatically lift or close itself. Some people may not want truck features on a Suburban, but I am not one of them, because of my years of experience. The tailgate feature really serves you well if you UTILIZE your Sport UTILITY Vehicle for Truck applications. If you are simply running errands for groceries and flowers, then you don’t need a gate and probably should be driving a Toyota Camry anyway. If you use your vehicle to pickup stuff at Home Depot, Costco, Furniture stores, or for beach bonfires, tailgate parties, Drive-in movies, camping and real life, then a tailgate is the way to go.

COST OF MAINTAINANCE AND EASY TO WORK ON
OK, this may be somewhat subjective, since I haven’t seen the bill to fix an electronically controlled feature that used to be manually operated (like the lift gate). However, I do know the cost of rebuilding a 6 speed tranny verses a TH400 is ridiculous. Plus parts are cheap, easy to find and easy to install on an old Chevy big block.

They want $50,000 to $60,000 for the new 2015 which is something I have a hard time getting my head around. I used to say, “you want that much for a truck!?!” But I can now tell you there is not much, if any truck in this Yukon/.Suburban. I thought SUV meant UTILITY, as in, it is sometimes UTILIZED as a truck. This does not seem to be the case here. This is closer to a minivan than a truck, which is a shame for most red blooded American males who happen to be the buyers of these vehicles. Unless GM can sell out strictly with men buying these for their soccer Mom wives, I think they need the red Blooded American male market and more TRUCK in this SUV

That being said, this vehicle is a great looking, and comfortable ride. It is great around town and a perfect freeway cruiser for a family. Before I test drove it, I would have been at a dealership to buy one, if I had the money for a new vehicle instead of home remodeling. The bottom line for me after the test drive is that my existing TRUCK has a lot more to offer than I imagined. For example, the new incarnation really needs to reconsider engine options and acceleration. Why must an EcoTec be forced upon us if we want a performance option or the power of a diesel? It also needs more front seat and third row seat leg room, much better visibility and smaller pillars. Although the 2015 would be great on the regular road trips we take, it still lacks the “MUST HAVE” wow factor I thought it had, and had many more “what the heck?” issues than I thought. I will look closely at changes for 2016 and reassess.
 
I envision a career change in your future as a automotive magazine writer. Thanks for this post.
 
I got back my Ole Burb. The first thing I noticed is how unobstructed my visibility is on the road. Those airbag filled pillars on the 2015 are a must have, because they obstruct your view so much, you are sure to crash. The next thing I noticed was the FEEL of accelerating from a light. My old suburban feels like a substantial machine that could pull a stump out of the ground at that very moment. Finally, I noticed the smile on my face, being reunited with a good family friend.

Of course I also noticed my ABS brakes suck and the pretty young ladies don't look my way anymore...
 
Ok the 2016 will have a heavy duty option for fleets but not the general public. This is a step in the right direction, but we still need the 2500 back and some engine CHOICES including a diesel. Apparently, GM wants me and the million guys like me to hold our current rigs and cash until at least 2017.
 
I didn't realize the only engine for the 2015 is the 5.3, surprising.
 
You can get a 6litre in the gmc Denali and it is standard on the escalade. I agree that it is surprising, but hopefully this will change. However, it would be nice if Ford And dodge had solid offerings so the competition forced the issue.

Jeep is bringing back the Wagoneer/grand wagoneer! It is said to have third row seating to rival the suburban's size and have multiple engine choices, including a diesel! This will be available in 2017 as a 2018 model year offering.
