Buick Lang Wei is positioned as a compact A-class car, which is the same as Volkswagen Sagitar and Ling Du. Lang Wei adopted Buick's patented mute technology. Aiming at the noise interference during driving, it applied a series of designs, such as 2.5-door sealing strip, 5mm thick sound insulation glass at the front door and 4mm thick sound insulation glass at the back door, to create a high-level quiet cockpit. The maximum power of Buick Lang Wei 1.5T SIDI direct injection turbocharged engine is 124kW/5600RPM, the peak torque is 250nm/ 1700-4400 rpm, and the acceleration of 0- 100km/h takes only 8.8 seconds. Its dynamic performance symptoms are equivalent to those of a large displacement engine. At the same time of turbocharging to improve power, the engine is equipped with SIDI central direct injection technology to make fuel more efficient, and the comprehensive fuel consumption per 100 kilometers is only 5.8 L.
In addition, Langdong is also equipped with an automatic engine start-stop function, which can greatly reduce fuel consumption and exhaust emissions for ordinary urban traffic jams and "stop-and-go" driving. Press the start-stop button on the central control panel to manually turn off the automatic start-stop function.
