2023 GMC Terrain To Get E-Boost Braking System

The 2023 GMC Terrain will come equipped with an electro-hydraulic braking system, GM Authority has learned. This means the crossover will follow in the footsteps of the closely related Cadillac XT4, which has featured e-assist brakes for a few years now.

GM introduced e-assist brakes on the Cadillac XT4 for the 2019 model year, making the subcompact crossover luxury automaker’s first vehicle to feature e-assist brakes. This system, which Cadillac says can enhance fuel economy and takes up less space under the vehicle’s hood, will now migrate to the 2023 GMC Terrain, as well, replacing that model’s traditional vacuum-assisted brakes.

GM says its e-assist brake system uses a control module “that interprets and converts driver brake pedal input and provides a corresponding hydraulic pressure output to activate a standard brake system.” The 13-pound, one-piece module eliminates the master cylinder, vacuum pump and hoses while incorporating electronic stability control, traction control and an electric motor to push hydraulic fluid to the brakes. This same system will also be applied to the 2023 Chevy Equinox.

According to GM Authority sources, the start of regular production for the 2023 GMC Terrain is scheduled to kick off on August 22nd, 2022. Only minor changes will be applied to the nameplate for the 2023MY, the most significant of which will be the introduction of a new turbocharged 1.5L I4 LSD gasoline engine. This powerplant replaces the turbocharged 1.5L I4 LYX gasoline engine. It will continue to feature the GM 9-speed automatic transmission only and sticks with the same GM D2 platform.

GM is set to increase production of the Chevy Equinox and GMC Terrain this year at the GM San Luis Potosí plant in Mexico, which is the only plant where the crossover is currently produced.

  1. The terrain stops fine the engine is whats needs to be upgraded not the brakes tiny 1.5 with 175 hp in the new engine coming out for 2023 it’s not going to make the consumer run to there local gmc dealers and order one bring back the 2.0 L engine that works fine and was good on fuel and lots of pep !!!

    1. Engine is well suited for this vehicle. It is very competitive and the turbo 1.5 puts out good torque down low which is important. Maybe whine about the mass engines in the Rav4 and Hyundai/Kia. Go drive one of those and see if you feel the same about the 1.5. No need to add cost and complexity for a demographic that has zero cares about what engine it has at a cost of MPG which is key (and price).

  2. More electronic control that will be expensive, software upgrades, another electric motor, all sound expensive when they you get a brake warning light. The vacuum assist has been around for for over 60 years and nearly fool proof. Rarely fails and not expensive to repair. Why fix what is not broke. Remember the ignition switch, as redesign cause deaths and ten of thousands of recall vehicles AND nothing was wrong with the previous one that was nearly fool proof.

    1. Mercedes tried this in the 2000s with the SBC braking system. While it has advantages and is a nice system for smooth braking it’s a very complex system with multiple failure points. Fortunately owners are covered by a 25 year unlimited mileage warranty on the system. Will GM be that nice and put the safety of customers first? Nope.

      1. News flash: eBoost has been shipping since MY 2019. Includes Corvette, Silverado/Sierra LD, Tahoe/Suburban/Yukon/Escalade, CT4, CT5, CT6, XT5, XT6, Blazer, and Acadia.

  3. Well the LSD engine explains all this Ms. Berra is hallucinating when it comes to this vehicle. This could be such an awesome little SUV at a great price point all it needs is maybe 220 hp but now they just can’t do that to me they have to put this brake system on here which is totally meaningless really disappointed I like this vehicle my wife has one with a 2.0 it’s a shame. Ms. Berra keep tripping .

    1. The 1.5 is a great little motor and situated right in line with the competition. It doesn’t need the 2.0, no one buys it. It will add cost and complexity and drive up prices. The people that buy this, I bet if you asked in a poll on the street 95% would have no clue on the engine size or horsepower. All this 1.5 complaint is laughable, it is a compact CUV, no one cares about the 2.0 outside of you, Don Chi and like three others that cry about it every article that mentions Equinox or Terrain.

      1. IIRC, 23%-25% of all Terrain sales had the 2.0l. That’s substantial enough to justify it.

      3. You are entitled to your opinion and that’s fine I Personally thinks it’s just a little under power for my liking like the 2020 terrain Denali I thought it was a perfect fit love that vehicle fun and some towing capacity with out jumping into a bigger s u v !!

  4. Vacuum assist braking will be like hydraulic steering. Phased out. More efficient, less weight, and same system can be used in EV. Get used to it. I am kind of surprised that 12v power has not been boosted to 24 or even 48V. Less current, smaller copper wires.

    1. Exactly what I was thinking, this new brake system was designed because of EV’s. Case in point? I have a 2021 Ram Hemi with etorque and auto stop. There is a vacuum pump with an electric motor for the brake vacuum. This new system definitely eliminates vacuum assist complexity with auto stop.

      1. I think the etorque system was a great idea. Inexpensive add with pretty good benefits.

    2. About thirty years ago Popular Science funded a research for vehicle battery voltage improvements. It turned out, at that time, upping the voltage to 43 volts was ideal. BTW, 48 volts for accessories would be the maximum safe voltage. Old mechanic telephone system worked on 48 v DC. Ring voltage was 70-90 volts 20 hertz and that you felt when working on a line and ring voltage came down.

      1. GeorgeS :

        In POTS areas (Plain old Telephone Service), with the tip and ring pair going all the way back to the central office (5 miles or more), therefore the loop length can be over 53,000 feet on #26 or #22 copper, the ringing voltage starts out there at 90 volts, 20 cycles per second – at least in the old Bell System companies like Verizon who never used frequency selective ringers for party lines, etc…

        Of course, cable phones and Verizon (FIOS) only need volts in the teens since the ringing voltage is generated in the basement of the house where the phone is.

    3. The fact that for 24 V, you need to drag around either a second lead acid battery, or at least a greatly expanded one, destroys weight benefits of the system under normal vehicle loads. The major load where high voltage benefits is hybrid propulsion, in which case you should go hundreds of volts anyway.

      The easy thing is aluminum wiring, like Toyota and Honda have been doing for a decade.

      1. LED lighting is becoming more standard that uses about 25% of power compared to incandescent lamps. Therefore, smaller gauge wire can be used.

      GM is one step ahead of you…. In addition to the vehicles mentioned, electric steering and electric brakes have been in the 2016-2019 volts, and all BOLTS. My 2014 ELR had the vacuum system but since the engine was rarely running it had an additional ‘vacuum’ compressor (or pump if you prefer) to allow the old-fashioned system to work…. The new system is much cheaper, and is easily integrated into any vehicle. Since the volume of hydraulic fluid to be pumped is small, the motor is VERY small, and easily runs on 12 volts, as does the steering..

      GM originally came out with the propoesed ’42 volt’ Wet Dream (really a 36 volt system) years ago. But then much more savvy suppliers came out with 12 volt electric steering – the ‘hardest’ system to make work on 12 volts… GM wisely DUMPED the silly voltage change out, choosing not to have to redesign everything for something different, or having silly voltage converters for everything that didn’t run on 12 volts.

      As far as ‘copper saving’ – the big change took place in the 1950’s in the USA and 1960’s in Europe with 12 volt over 6 volt systems – not that the 6 volt systems were bad, but the 12 volt systems required only 1/4 the copper, and certain things like ‘Vibratorless’ Delco Radios (extremely cost reduced and energy efficient) could only run on 12 volts….High performance v-8 engines (prior to electronic ignitions) had much less expensive ignitions with 12 volts over 6….

      There however in a 12 to 36 or 48 volt change simply isn’t enough benefit to change an existing accessory standard wholesale…. But the intrinsic savings of Electric Steering and Brakes – all running off the existing 12 volt systems – are big cost reducers, and much more probably – reliability increasers.

      Of course – most here will hate it – when most haven’t even seen or experienced it, prefering the old Mark Twain quip:

      “I’m all in favor of Progress…….. Its CHANGE that I don’t like! “.
