We’re spending this week with the 2019 GMC Terrain. Our model is powered by the turbocharged 2.0L I-4 LTG engine mated to the new GM 9-speed automatic transmission with all-wheel-drive.
The CUV is finished in the SLT trim and features the sinister-looking Terrain Black Edition in Ebony Twilight Metallic with a Jet Black interior. In other words, a black car with a black interior and a black package. An all black GMC Terrain, if you will.
We will have this compact crossover for the week, so if you would like to know more about it beyond the spec sheet, ask your questions about the 2019 GMC Terrain in the comments section, and we’ll reply in a timely manner as part of the GM Authority interactive review.
Ready…. set… go!

My wife has a ’19 Terrain Denali and it is wonderful. She came from a BMW X1 M-Sport and the Terrain bests it (in our opinion). The fit and finish, along with the materials used, are dead even. Both are of high quality. The HD 360 camera in the Denali is a bonus, as is the 2.0L turbo and panoramic sunroof. The 2.0L can get up and go! Another area that the GMC shines over the BMW, is the cabin space. The BMW did not make good use of this. The GMC takes advantage of every square INCH!
IMHO, the ’19 Denali is more refined than a ’16 BMW X1 M-Sport. GM really did a fine job.
My wife also have ’19 Terrain Denali and it far cry from luxury fit and finish. The cabin full of cheap plastic and uneven leather stitching. Do me a favor, go to your Terrain and look under steering wheel dashboard, above pedals. You will see a huge hole where you can see a steering wheel shaft. This should never be visible and a potential safety risk.
If you’re so unhappy, I suggest you return it ASAP. Return it, demand you money back and demand that they buy you a direct German competitor for ~$10k more. Please update us at your earliest convenience.
How is that a safety risks seeing the steering shaft? You think a little cover is going to be safer? Most cars have those exposed to a point, some are more covered up than others. I like how you call it cheap hard plastic, every car I’ve been in looks similar and difference is the grain. Yes some have more padding in places but most don’t care. I have 2019 Terrain Denali and my leather is perfect. If it looks as bad as you say have them replace it. My 2016 Cruze premier had leather and besides the texture differences in the seat all the stiching was top notch and two toned. Is my Terrain perfect no, but it funny I have noise in my headliner that i’m going to have the dealer fix, but when I google the problem it seems these 100k plus luxury cars have the same problems and issues.
For anyone looking to get a Terrain, get the 2.0t its worth the extra money. I’m typically getting 30 plus on the highway at 75mph.
Joe, was curious about the noise in the headliner. We have an occasional light rattle noise that seems to be coming from maybe the grab handle on the drivers side. Is that by chance the same area your noise is coming from?
Interesting you bring that up, Tom. I am noticing a rattle in my tester as well. Not sure if it’s coming from the grab handle above the driver’s side or from the area in the B-pillar, behind the driver’s seat. It’s ever so slight…. but noticeable.
Would be interested if anyone knows a cure .
Alex, I have this slight rattle in the same place as yours on my 2020. Did you ever figure it out?
You know I did not look as closely maybe your correct. It’s a price point issue. If you drive more of a premium car of course you will spot some “short cuts” . However I think it will run well and fit her needs. She loves it. It is NOT a Denali. OK apples and oranges.
Infamous – I would have to totally disagree about the Terrain being more refined than the BMW X1.
Maybe there are elements in the cabin that are more useful or spacious, I’ll give you that… but when it comes to the driving experience, the Terrain is not at all “more refined” in any way… especially in the powertrain department.
Even with the 2.0L LTG, the Terrain doesn’t feel great. It’s okay at best, even though anemic is the better word. And even more so, it’s really rough in this application. I had to look a few times at the sticker and then do a VIN verification because I just could not believe that my tester had the 2.0L Turbo… I kept thinking it’s the 1.5L Turbo. The BMW X1 with its 2.0L turbo feels extremely good. The entire powertrain feels silky smooth to the point where I would call it the benchmark in transversely-mounted 2.0L turbo engines.
From a space standpoint, the Terrain is physically bigger. In fact, it’s a size class larger than the X1 and it shows inside. From a material quality standpoint, I would say the two are comparable. BMW, however, nails it when it comes to the little things like cargo organization and cargo tie-downs.
Infotainment and in-vehicle tech is better in the GMC, hands down. It’s not bad in the BMW, but it’s a generation ahead in the GMC.
When you start stepping up into the higher trim levels with the GMC, you start hitting a price point where you could get a really well-equipped BMW X1, which also has the longer warranty. I’ll leave it at that for now.
Alex, I think your comments about the 2.0L LTG are very unfortunate. I have the 2.0L in both the equinox and camaro, and its been nothing short of a powerhouse of a little engine that feels very quick and responsive, especially behind the 9-speed auto in the equinox, but also behind the Tremec in the Camaro. It’s an adaptable engine that gets extremely good gas mileage. Watch the TFLcar video where they drive the 2.0T equinox extensively to get a good idea of why the equinox/terrain twins sell so incredibly well. In reality they are at least on par with german rivals, a better value initially AND cheaper to maintain. BMW has a stronger warranty because you’ll need it eventually. Most everyone agrees the LTG feels great to drive and makes good power down low, so I’m really scratching my head over how you can dismiss this modern powertrain, that serves so well in so many functions, so easily.
Brian – I’m intricately familiar with the LTG, having had it in two of my personal cars and having spent countless hours in vehicles that were not mine. I live and breathe GM, running GM Authority for a living. In fact, I worked for GM in the past. That should give you an idea of where I’m coming from. Overall, the engine is okay. Just that – okay.
Furthermore, the LTG has extremely little to do with the commercial sales success of the third-gen Equinox and Terrain. The success has more to do with the overall vehicle equation (pricing, packaging, value, rebates) than the LTG. You would be very hard-pressed to find anyone who bought the Envision and Terrain SPECIFICALLY and SOLELY because they wanted the 2.0L turbo engine.
To say that the Equinox and Terrain are on par with German rivals is way off base. I’ve spent considerable amount of time with the German rivals and the powertrain refinement levels are vastly superior, especially when it comes to BMW and VW (the 2.0L from Mercedes doesn’t feel as refined). In fact, this lack of refinement is exactly why the LTG is being replaced by the all-new LSY. In general, the LTG does its job, but it doesn’t do it in a very refined manner.
“BMW has a stronger warranty because you’ll need it eventually.”
That’s an old-wives tale that applied years ago. BMW has a longer warranty because it is positioned in North America as a luxury brand and its warranty is on par with that of other luxury brands (Mercedes, Audi, Cadillac, Lexus, etc.).
“I’m really scratching my head over how you can dismiss this modern powertrain, that serves so well in so many functions, so easily.”
Not sure why you feel I’m dismissing it. Take my words at face value: the LTG does its job but not in the most refined manner. Is it ok for the Equinox and Terrain? Yes. But there is room for improvement. Hence why there’s the LSY.
also are you sure it has 100% premium fuel in the tank? You sure you aren’t on the low octane timing table?
Alex, I agree with Brian. The 2.0L Turbo in the Denali is quite stout. Now, it’s not my ’11 Camaro SS or my ’17 Grand Sport, but when we picked it up, I mashed the gas (in FWD mode) and it twisted the tires. 252hp isn’t eye-popping, but it’s no slouch either. My wife’s X1 M-Sport had 228hp and an 8-speed auto. The M’s get paddle shifters and it did shift very quick, but the 9-speed in the GMC is on par with it, IMHO.
As for the interior layout, as I said, the GMC makes better use of the cabin. For instance, if the cup holders were occupied in the BMW, the storage space was limited. Both front doors had one very small storage area on the base and the console had one very small storage area which was covered up by an arm rest. You were always juggling items around, trying to find a place to set them. The layout was poorly designed.
As for price, I checked every box on the BMW’s order sheet, except the upgraded stereo and the 19″ M-wheels. The 19’s come with summer only tires, so I ordered the 18″ M-wheels with all-seasons. My wife’s Denali has every option and the BMW still stickered for ~$4k more. In the end, the BMW was very nice, but my wife prefers the Denali.
Infamous: as I mentioned to Brian above, I am very much familiar with the LTG, having had it in the ATS and CTS (personal cars) and in the Regal (previous company car). I had the ATS for 39 months, the CTS for 24 months and the Regal for 6 months.
When I got in the Terrain, I had to do a double take on the sticker and then do a VIN verification to make sure the sticker wasn’t wrong and that this unit actually had the LTG, rather than the 1.5L turbo LYX. Then I had to go back and make sure that I entered the VIN correctly into the VIN verification tool… since I simply could not believe that I was driving the model with the LTG.
My only ounce of hope is that someone filled it up with 87. I don’t know what octane was put into the Terrain I’m driving by the firm that handles these cars, so I’m going to try and drain the tank (by driving a lot 🙂 ) and filling it back up with 91 and seeing if it feels any different.
I don’t think the expectation is for the LTG is to be eye-popping. But it should definitely not make one question whether the model in question has the 1.5T or the 2.0T.
But even in the cars that I mentioned before, the LTG always left a lot to be desired in the refinement department. Actually I’ll put it this way: if the LTG existed in a vacuum/by itself, it would be the best engine ever. But comparing it to same-displacement engines from BMW and VW reveals the refinement issues I’m referring to.
Also, I agree with you as it relates to the storage areas of the X1. That’s something BMW didn’t do a great job on. There’s not even a place to put a modern phone (iPhone X, not even the huge Max). No matter where I put my iPhone X in the BMW, it slid around no matter where it was – in the cupholder or the more horizontal space ahead of the gear selector. By comparison, the Terrain has a significant amount of useful storage spaces that enable one to store cups, a phone, wallet, etc. That a bright spot on the Terrain for sure.
I guarantee you are driving the the terrain with 87 octane in it. I had 87 octane in my equinox 2.0T when I bought it from the dealer. It felt terrible. I spent 15 minutes teaching my salesman about octane ratings and why it is important to use 92 in LTG engine cars, he had no clue at all. It will take time to convert the tables back to high octane. I wouldn’t judge the vehicle until then.
Regarding the LSY–its reason for existence is not “the LTG is not refined enough.” Not at all. It’s a 2.0L that, at least in the crossovers, is tuned for max low rpm torque and max fuel efficiency, with the addition of AFM and start/stop. Nothing about it is more “refined.” It’s simply a more efficient engine in the city. There is zero difference in “tefinement.”
By the way, what exactly do you mean by “refinement”? And how precisely are german powertrains “vastly superior” to the LTG on that definition? Is it engine balance? Is it throttle response? Or is it the transmission and not the engine at all that we are talking about? I’m very interested to hear your definition there, because you used the word a lot of times, but never explicitly said what you mean by it.
yeah, I often sit upside down in my seat with my head by my pedals. It really matters to me what the tops of my knees are seeing.
Saying you’re driving a 2019 GMC Terrain SLT without specifics is vague; but given you didn’t say diesel means you have the 1.5L DOHC-4v 4-cyl turbo with 170 hp and 203 lbs-ft of torque; the only real question is that whether this is sufficient especially if the Terrain has 4 adults and is trying to go up a steep hill. One has to wonder whether another 100cc of engine displacement from the LWC 1.6L DOHC-4v 4-cyl turbo from the Buick Cascada that makes 200 hp be a better fit.
the 2.0 T is an option on the SLE/SLT
This same package can be had in a 2.0T. It would indeed be nice if he had specified.
Omegatalon: it could mean I have the turbo 1.5L LYX or the turbo 2.0L LTG. I have the LTG.
I did not specify at first because I had to do two VIN verifications to be completely sure this one had the LTG. I just couldn’t believe it because it felt much weaker, as if it were the LYX.
The 1.5 Turbo is more than adequate. I have a 2019 GMC Terrain SLE with over 6,700 miles on the odometer and it has been a joy to drive!
Have they gotten rid of the nonsensical shifter switches yet? Not going to buy one until there’s a proper lever shifter.
Reminds me of 1970’s when push button phones came out…
Ron,
The push/pull button gear selection mechanism is present and accounted for. I got used to it within two days of driving. It’s a good mechanism and works well, and I think of it as a positive for two reasons.
First off, it’s something different that adds some excitement to the car. Of the three people that have gotten into the Terrain with me so far, all three have asked about where the shifter is. After I told them, their reaction is along the lines of “huh, that’s pretty cool”… followed by a recognition that GMC is doing something innovative. It’s good marketing on a product that speaks for itself.
The second reason is more practical: the shifter frees up a significant amount of space within the center console, creating a lot of storage space and large cupholders.
Overall, I embrace this shifter and don’t understand why people seem to deride it, simply for being different.
what is it like with the push button gear shifters? does it feel weird?
My wife and I were skeptical at first, but by the 2nd or 3rd time you drive it, the buttons become second nature. It’s truly no big deal. Some people are making it a big deal because it is atypical. Plus, without a shifter, you gain more storage space, which is very handy.
As I mentioned in an earlier comment, I got used to it within two days of driving. It’s a good mechanism and works well, and I think of it as a positive feature for two reasons.

What engine? How does it compare to the diesel since you didn’t say what engine you have
Will 2.0L turbo eng be available in Terrain ?? Your loaner is probably a V6
the don’t make v6 anymore for terrain
Ron – the engine in the one I’m driving is the 2.0L Turbo. There is no more V6 for the second-generation Terrain, which was introduced for the 2018 model year. The engine lineup for 2018 and 2019 is as follows:
1.5L Turbo LYX gasoline making 170 horsepower and 203 pound-feet of torque
2.0L Turbo LTG gasoline making 252 horsepower and 260 pound-feet of torque
1.6L Turbo LH7 diesel making 137 horsepower and 240 pound-feet of torque (discontinued for 2020 model year)
Does the current Terrain soak up the bumps any better than the 2017 and previous models? I have a 2016 that rides like it has solid tires. Hate it. Lease is up in November and will probably go for another Terrain anyway. Also how is the 1.5 liter engine in mountainous terrain? My current 2.4 liter runs it heart out on anything other than a minor grade on the freeway.
I would say it soaks up the bumps quite nicely, yes.
The important part is that the overall feel of the second-gen Terrain is different from the first-gen in that this feels like a less “brutal” vehicle. It drives light and small, and in doing so, it soaks up the bumps well.
I have the 2.0L Turbo in the one I’m driving and am doing so in the sea level flats of Miami, so no direct comments on the 1.5L in the mountains… but I would expect both the 1.5L Turbo and the 2.0L Turbo to perform better that the N/A 2.4L in your 2016.
Thanks Alex. Haven’t driven the current Terrain yet, but that’ not far off. Live in Tucson at 2,600 ft. However the Santa Catalina mountains are just north of town, but we visit Summerhaven at 8,000 feet + a couple times a year, and going to San Diego, or Flagstaff requires some mountain driving. Looking forward to the new wheels.
I have been driving a 1.5 Turbo SLE model Terrain for a year and a half now. I live in Just north of Denver at almost 5,000 feet above sea level and it handles well. Since the new Terrain is 300 lbs lighter than the 2017 model with the 2.4 liter Naturally Aspirated engine, the 1.5 turbo has plenty of torque at 203 lb ft for the mountainous terrain. I have never struggled to pass and I have several customers who have driven the 1.5 turbo model through the mountains as well with no problem. I can’t justify the added cost of the 2.0 turbo since I’m currently in a 3 year lease unless I opted for Denali model where it is standard.
Thanks for info Alfonso. That sounds encouraging performance wise. 99% of my driving is on relatively level ground, so I’m hoping for better mileage than the current 2.4L engine, yet get adequate performance on the occasional mountain road.
I have consistently averaged a solid 22 miles per gallon in town and 30 miles per gallon on the highway and the ratings on paper are 24 mpg city/28 mpg hwy compared to the 2.4 liter 2017 Terrain that I leased, on paper it was rated at 20 mpg city and 28 mpg highway. I could get at the very best a solid 18 in town and 26 highway.
How is the ride on the 19inchers? Also what’s the fuel range between the AWD and FWD? Does the FWD have smaller gas tanks than the AWD?
I like the ride on the 19s. It’s not too stiff and not too floaty. Granted, I’m driving it on near-perfect Miami roads… so rougher terrain or more abused roads could be different.
I’m planning on doing a long drive with it soon and will let you know about range then. I have the AWD model.
FWD has a smaller tank (14.9 gallons / 56 liters) than AWD (15.6 gallons / 59 liters).
We just leased a 2019 Terrain for my Grand daughter for her to take to school in Idaho from Sacramento. Winters are rough where she is going so we got her AWD. Gosh I was so impressed with this SUV for the money. I was stunned. Her color is Gum metal grey beautiful car. Now I know there 2 types of 2.0. I think one is a turbo that makes 259 HP, she got the other one. I love the looks of this Black one. I would like to know he specs. on it. Thank you
Robert – that’s great. The Terrain is definitely a good car.
The engine lineup for 2018 and 2019 Terrains is as follows:
1.5L Turbo LYX gasoline making 170 horsepower and 203 pound-feet of torque (this is the base engine)
2.0L Turbo LTG gasoline making 252 horsepower and 260 pound-feet of torque (optional engine)
1.6L Turbo LH7 diesel making 137 horsepower and 240 pound-feet of torque (optional engine, discontinued for 2020 model year)
How are those low profile tires on pothole strewn roads?
How is acceleration?
Comfort?
Seat Comfort?
Rear visibility?
The tires are fine, but Miami doesn’t have many potholes. Will try to find an old road to report back on that.
The topic of acceleration is currently on hold, as per my comments above about the engine. Will try to fill this thing up with 91 premium and report back after doing that.
Comfort is top notch. The car is very comfortable all around.
Seat comfort is good. Lumbar adjustment is a welcome feature. But I would have loved to see tilting headrests in the Terrain, which it doesn’t have.
Rear visibility out of the rear glass is good… out of the windows above the cargo area/trunk is limited. But that can be mitigated via the Blind Spot indicators. I don’t see it as much of a problem.
I own a 2019 EQUINOX Premier…….1.5L Turbo. First, the 1.5 Turbo is 100% better than the old 2.4L engine. I had a 2010 Equinox, a 2013 Terrain, and a 2016 Equinox. Although the commercials say GMC is the professional grade vehicle, there’s not a dime’s worth of difference between the NOX and the Terrain. The interiors are identical. The running gears are identical.
I bought the NOX to stay away from the push button shifter in the Terrain. My friend who has Parkinson’s bought a new Terrain DENALI four months ago and is trading it in as I type. With his disability, the push button is a no go for him. In addition the 2.0 Turbo requires PREMIMUM FUEL for best mileage and performance………..My experience was test driving a 2018 Terrain in the winter. With gloves on, the shift buttons were hard to maneuver.
My Equinox Premier base model was $34K………..loaded, $43K………..sometimes I wonder.
Both the NOX and the TERRAIN are the best of the worst……….but the HONDA CRV that has a lower sticker and better options…..so they say!
Was wondering about that third roll window? I felt it was so tiny in the 2018 that it was a safety issue. I realize you have the backup camera but I’m old school I prefer to use my mirrors and windows. I do like the backup camera it’s made checking for objects directly behind the vehicle so much easier. But not much help in viewing the sides . I feel those third roll windows would be so much more beneficial if made larger. Gonna purchase a new vehicle by summer’s end am considering the Terrain but the window issue mite possible turn me off.
I imagine that by “third roll”, you mean “third row” 🙂
If you’re worried about seeing to the sides of the vehicle when backing, the windows above the cargo area won’t help. But what will help is a neat feature on all GMC vehicles called reverse mirror tilt. You can set the exterior wing mirrors to tilt downward when in reverse, which helps see the ground to the sides of each rear wheel. You can set either of the mirrors to tilt down, or both of them – it’s up to you.
The setting for this can be found in the center screen via Settings > Vehicle Settings > Comfort & Convenience > Reverse Tilt Mirror. I think this accomplishes what you’re looking to do via the windows.
WOW! Is reverse mirror tilt a feature of the Terrain? Experienced this on a rental car once and it is fantastic! Not quite 360° vision, but almost as good.
Hank – yup, Reverse Mirror Tilt is a feature of the Terrain (and all other GM vehicles, though the legacy products like Express/Savana vans might be an exception).
It really does help a lot, like you said… especially when backing and parking… or both!
The caveat is…from the 2019 Terrain Owner’s Manual
“Reverse Tilt Mirrors
If equipped with “memory seats,” the
passenger and/or driver mirror tilts
to a preselected position when the
vehicle is in R (Reverse), if enabled.
This allows the curb to be seen
when parallel parking.”
Not ALL Terrain/GMC…
Folding front seat, love it or leave it? Could it function as a makeshift desk when out in the field (hold a laptop and some paperwork?
I have a 2015 Terrain with the 300hp V6. I was disappointed that they dropped the V6 for 2019. Do you think the turbo 4 is OK compared to the 3.6 V6 or are they trying to get MPG up?
Jim, I get this one often – and the answer is a bit involved.
The 2.0L Turbo gets the Terrain moving… but not in the same way that the V6 in the last-gen model did. Now, the power-to-weight ratio of both the first-gen Terrain with the V6 and the second-gen Terrain with the 2.0L Turbo is roughly the same… so they perform similarly… but the feel is totally different.
Off the line, the 2.0L Turbo has that infamous turbo lag that small turbo engines are known for. Once you’re going and the engine is at about 2000 RPM, things get better. Truth be told, I had to look at the monroney three times and do two VIN checks to make sure the unit I am driving has the 2.0L Turbo and not the 1.5L Turbo.
A friend has the second-gen Equinox with the V6 and he isn’t going to the Equinox with the I-4. Instead, he’s going to the Blazer with the V6. Bottom line: the two engines do their job on paper, they feel very differently doing so from a “feel” standpoint.
We have a 2018 GMC Terrain , love the car with the exception of the fuel saving option that stops the motor when you stop. We live in Louisiana and even 30 seconds without the AC blowing changes the temperature inside the car. I wish this could be deactivated. My wife can’t stand this and we are considering trading it in because of it. Was looking at the new Blazer until I noticed the same option is standard on the Blazer!
If you press L instead of D then ( if it’s a nine speed ) press the + button nine times look on the dash it will show L 9 then the car won’t shut off when you stop , you have to do this every time you start the car. It’s kind of a pain but you get used to it. I have an Equinox with a 6 speed so again I put the shifter in L and hit the + 6 times on the dash it shows L6. I’ve had the car for a year and I don’t even think about it.
With regards to KIM PANEPINTO’s post………..GM doesn’t get it. I a recent GM Authority Story on the new 2020 ACADIA, they are going to the push button shift, but they are adding a defeat switch to override the start-stop issue. Both the Equinox and Terrain have start stop that can’t be turned off. I like my Equinox but the start stop is a true pain!!!! 99% of the time, I shift to Low and then toggle up to 6th gear………..this disables the start stop. In a TERRAIN…………toggle 8 times to 9th gear………
I try to be loyal to GM………but there are days that makes me wonder.
BTW………..the 2.0 Turbo gets 2-3 mpg less than the 1.5 Turbo and PREMIMUM FUEL is 20 cents more per gallon in my area.
I’m sure the Terrain/Equinox refresh will have a defeat switch. But even with that you have to press it every time you start the car. So either way it’s not a big deal too me.
I test drove a few Terrains, both low end I4T and the 2.0T I4.
My question is why GM don’t focus on better NVH attenuation? When I floored the 2.0T the whole thing shook and vibrated like a giant gas-powered dildo. Horrible experience.
Leasing a 2019 Terrain, Denali package, Love it. 2.0 turbo has more get up and go than the 2016 I was leasing with a 6 banger. 19 inch tires are fantastic, only thing I don’t like is the auto shut off but can live with it. Use 91 octane gas with no ethanal, average 25 mph in city.
If your saying the 2.0t is slow and turbo lag, something sounds wrong. My Terrain will just go and take off. Its all factory and its quick. The 2.0t has dual scroll turbo charger so lag should be little to any. Wondering if they filled the car with 87 instead of premium which would cause some loss of performance.
I tow a wave runner and ATV at times with mine. It has no issues moving them and getting up to speed. Everyone who has drove it thought it was a V6 not a turbo.
It could very well be filled with non-premium fuel. I’ll try to drain it and fill it up with the good stuff.
Like I mentioned in my earlier comments, it did not feel like the LTG I have come to know in various other vehicles that use it.
It would be a good idea to use 91 Premium Octane in either the 1.5 Turbo or the 2.0 Turbo. I do notice a slight difference in acceleration/throttle response when filling up with 91 Premium Octane compared to 87 Octane.
GMC’s specs show a really large turning radius, probably to allow the large wheels. Is the maneuverability as bad as the specs would lead one to expect?
Well, the turning circle is pretty good from what I’ve noticed thus far.
The 2018-2019-2020 model is as follows:
37.4 / 11.4 (17-in. wheels)
38.4 / 11.7 (18-in. wheels)
41.6 / 12.7 (19-in. wheels)
The first-gen model was worse:
40.0 / 12.2 (with 17- and 18-inch wheels)
42.6 / 13 (with 19-inch wheels)
In the real world, the maneuverability is pretty good. I haven’t noticed any issues in this area.
