What engine does the Buick Regal use?

[SophieMarie]

Buick Regal uses a 1.5T turbocharged engine and a 2.0T turbocharged engine. A turbocharged engine refers to an engine equipped with a turbocharger. Taking the 2020 Buick Regal as an example, it belongs to the mid-size car category with a length of 4904mm, width of 1863mm, height of 1461mm, wheelbase of 2829mm, fuel tank capacity of 55L, and trunk capacity of 441L. The 2020 Buick Regal is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 169PS, maximum power of 124kW, maximum torque of 250Nm, and is paired with a 9-speed automatic manual transmission.

Just helped a friend pick up the new Regal and had researched its powertrain. The current main offerings are the 1.5T and 2.0T turbocharged engines. The GM LSY series 2.0T is packed with cutting-edge tech, featuring intelligent cylinder deactivation that shuts down two cylinders in traffic, achieving a combined fuel consumption of under 8L/100km. The older model used to have a 2.0L naturally aspirated engine, which is rarely seen now. It’s paired with a 9AT transmission, delivering exceptionally smooth shifts from a standstill. For friends in northern regions, the 2.0T is recommended—its direct injection + twin-scroll turbocharging ensures more stable performance during cold starts in winter.

With ten years of experience in automotive repair, I've disassembled over a dozen Regal engines. The current lineup is equipped with a steel-chain 9AT transmission, unlike some brands that use steel belts which are prone to slipping. The engine core codes are LFV for the 1.5T and LSY with Tripower valve management for the 2.0T. During repairs, I noticed a detail: the intake piping features a resonant cavity design for noise reduction, making it significantly quieter than German cars. However, attention should be paid to the integrated exhaust manifold in the cylinder head design, as it dissipates heat slightly slower in summer, making regular cleaning of the radiator grille crucial.

Last week I test drove the new GS version on the track, and that 2.0T engine was tuned really aggressively. With 174kW power and a three-stage sliding camshaft, the acceleration suddenly kicks in when the RPM exceeds 4000. Compared to the Camry Hybrid in the same price range, the Regal's turbo engages faster. However, during aggressive driving, the transmission oil temperature tends to rise easily, so I'd recommend brothers who plan to modify it to install an oil cooler. The standard 1.5T is sufficient for city driving, but you can clearly feel the lack of power when climbing hills with a full load and the AC on.

As a used car appraiser, the Regal's engines can be divided into three generations. Before 2010, it used the old LTD series cast iron engines, which are now commonly seen in the used car market with oil leakage issues. Starting with the 2014 model, it switched to the SIDI direct injection engine, which has a higher failure rate for the throttle body. The current eighth-generation model is the most reliable, featuring an aluminum alloy cylinder block that is 21 kg lighter and a crankcase with a labyrinth-style oil-gas separator. For used car purchases, it's recommended to choose models from 2020 or later, as the cylinder deactivation system has been upgraded to the third generation, significantly improving oil consumption control.
