The Buick Regal was completely overhauled (redesigned and re-engineered) for the 2018 model year, ushering in the sixth generation of the Regal nameplate while introducing three body styles:
- 2018 Buick Regal Sportback – a new body style with five-door versatility yet a sedan-like appearance, available in the United States and Canada.
- 2018 Buick Regal TourX – a wagon with the driving dynamics of a car but all the usefulness of an SUV, available only in the United States.
- 2018 Buick Regal Sedan – a standard sedan body that features a slightly longer decklid but less versatility than the Regal Sportback, available only in China.
The 2018 Buick Regal is offered in three body styles globally, depending on market.
Body Style | Market | Predecessor |
---|---|---|
Regal Sportback | United States | Regal Sedan |
Regal GS (Regal Sportback GS) | United States | Regal GS Sedan |
Regal TourX | United States | None |
Regal Sportback | Canada | Regal Sedan |
Regal GS (Regal Sportback GS) | Canada | Regal GS Sedan |
Regal Sedan | China | Regal Sedan |

2018 Buick Regal Sportback offered exclusively in North America

2018 Buick Regal TourX offered exclusively in North America
Buick also introduced a high-performance Regal GS for the 2018 model year. However, the 2018 Buick Regal GS refers to two different models, depending on the market:
- In the United States, the Regal GS is available exclusively in the Sportback body style and features upgraded drivetrain components, including an upgraded engine, as well as enhancements to the exterior and interior.
- In China, the Regal GS is available exclusively in the sedan body style and features enhancements to the exterior and interior, but does not have any drivetrain upgrades.
The sixth-generation Buick Regal is available in several body styles and variants across various global markets.
Following are all the major derivatives of the sixth-generation Regal family.

More information:
Though we initially believed that GM would reintroduce the Regal Grand National and high-performance Regal GNX on its rear-drive Alpha platform, such a vehicle never came to market. Instead, GM elected to maintain the Regal family as a front-drive midsize vehicle family.
See our initial, though incorrect, expectations about the 2017 Buick Regal Grand National and 2017 Buick Regal GNX.
It’s believed that Buick’s decision to replace the Regal Sedan with the Regal Sportback in the United States market is associated with the market shift from sedans and to crossovers. Buick itself states that the new Regal Sportback and Regal TourX represent two new products that expand the expectations and opportunity for individuality in the premium midsize segment.
In the U.S., the Regal slots in the premium midsize segment and has the following competitors:
Buick Regal Sportback Competitors (U.S. market)
- Lexus ES
- Acura TLX
- Audi A4 Sedan and Audi A5 Sportback
- Volvo S60
Buick Regal TourX Competitors (U.S. market)
- Audi A4 Allroad
- Subaru Legacy Outback
- BMW 3 Series Wagon
- Volvo V60
Meanwhile, sedans remain strong in the Chinese market. For that reason, Buick didn’t feel the need to offer the new Regal in any other form factor there other than the sedan. In China, the Regal Sedan competes in the premium medium/large executive sedan segment with the following models:
- Acura TLX-L
- Lexus ES
- Peugeout 508
- Volkswagen Passat (Ling Du)
The 2018 Buick Regal family is offered with the following engines and transmissions globally.

Following were our expectations of the 2018 Buick Regal prior to its official unveiling:
- Available in four-door sedan (Buick Regal Sedan) and five-door wagon (Buick Regal Wagon or Buick Regal Tourx) body styles
- Longer than the model it replaces, with more interior room, especially in the rear seat as a result of a longer wheelbase and more efficient space utilization
- Unveiled in 2016 or 2017 as a 2018 model year vehicle
- All-new exterior design in line with the latest Buick-Opel-Vauxhall design language
- All-new interior that is of a higher quality and is also more space-efficient than the last-gen model, resulting in more interior room
- Based on GM’s new global E2XX platform directly shared with the 2016 Chevrolet Malibu, giving the 2018 Regal a transverse engine orientation sending power to the front wheels asstandard with all-wheel drive as an option
- We expect the 2018 Regal to be roughly 300 pounds (136 kg) lighter than last-generation Regal thanks to the light-weighting efforts of the new E2 platform. The lighter curb weight will result in better fuel economy as well as driving characteristics such as acceleration, braking, and handling
- New turbo-charged engine lineup:
- The base engine could be the new 1.5L LFV Ecotec motor
- The up-level engine will likely continue being the 2.0L Turbo I4 LTG in the Regal Turbo
- All engines will likely be mated to an eight-speed automatic transmission
- The latest IntelliLink infotainment system
- The latest active safety, driver assistance, and accident prevention systems
- High-performance Regal GS model will likelky return making 300 horsepower and 300 pound-feet of torque, sending power to all four wheels via an advanced all-wheel-drive system
- Starting from the mid-$30,000 range
- Very closely related if not identical to the upcoming 2017 Opel Insignia/Vauxhall Insignia and next-generation 2018 Holden Commodore
