Three months after the international debut of the all-new Buick Verano Pro in China, General Motors has just confirmed that the next-generation compact sedan will feature an all-new powertrain. As such, the Verano Pro was the model chosen to introduce a high-tech, efficient turbocharged four-cylinder engine to enhance the performance of the company’s vehicle portfolio.
The Buick Verano Pro will be the first vehicle to adopt the turbocharged 1.5-liter engine that’s part of the eighth generation of GM’s EcoTec engine family. It was developed based on the company’s global engine architecture to meet both the strictest standards emissions and the needs of younger buyers. The engine features a modular design that offers multiple power outputs and low fuel consumption.
Although the automaker has not officially announced it, we’ll assume that the new turbocharged 1.5L engine is the same one that the Chinese authorities leaked last month for the 2022 Buick Envision range. SAIC-GM’s statement for utility vehicles indicates that the new engine will carry the RPO code LAH and is capable of producing an outstanding 150 kW, or the equivalent of 201 U.S. horsepower.
In the new Buick Verano Pro, the all-new turbocharged 1.5-liter engine generates 135 kW or 181 horsepower, the highest output so far for the compact car, along with 250 Nm or 184 pound-feet of torque available between 1,500 and 5,000 rpm. Coupled with a modern continuously variable automatic transmission, this powertrain configuration allows the Verano Pro to accelerate from 0 to 60 mph in just seven seconds, making it a responsive and fun car to drive.
In addition, the new powertrain promises to improve the Buick Verano Pro’s fuel efficiency by 6 percent compared to the second-generation model, according to the stringent WLTC test procedures. This also enables the vehicle to meet China’s latest 6B national emissions standard, offering combined fuel consumption as low as 5.95 L/100 km or 39.5 U.S. mpg.
Aside from the Buick Verano Pro, the all-new turbocharged 1.5L engine will soon be rolled out in products of various brands and segments of GM’s portfolio in China. It can be combined with a nine-speed automatic transmission or a CVT, and is compatible with 48V mild-hybrid, HEV and PHEV systems. Its launch expands the company’s robust global powertrain lineup, which includes turbocharged 2.0L, 1.3L and 1.0L variants of the EcoTec engine family.
