All-New Buick LaCrosse

SAIC-GM’s new-generation Buick LaCrosse sedan, which goes on sale in China next month, will come with new high-efficiency powertrains and an upgraded chassis. It will take performance, fuel efficiency and comfort to a new level in the premium passenger car segment.

Highly Efficient Powertrains

The new Buick LaCrosse is being offered in China with a choice of powertrains. The top-of-the-line LaCrosse 28T is powered by GM’s high-performance 2.0T SIDI engine, which was named a Ward's 10 Best Engine. The engine incorporates advanced technology such as a twin-scroll turbocharger, intelligent inline direct injection, a tooth camshaft drive chain, a variable displacement oil pump and an integral balance shaft mounted low in the oil sump to maximize efficiency.

Paired with an upgraded intelligent six-speed DSS transmission and incorporating start/stop technology, it generates a maximum output of 192 kW and peak torque of 350 Nm. The powertrain combination enables the new Buick LaCrosse to sprint from 0 to 100 km/h in 7.4 seconds while achieving combined fuel consumption of 7.6 liters/100 km.

The new Buick LaCrosse 20T is equipped with GM's new-generation and efficient 1.5T SIDI engine, which features an advanced structural design and cutting-edge technologies. They include mid-mounted direct injection, a variable displacement oil pump, an integrated cylinder head/exhaust manifold, a patented ultra-quiet inverted-tooth camshaft drive chain and an all-aluminum split cylinder block.

The engine is matched with a seven-speed intelligent dual-clutch gear transmission and includes fuel-saving start/stop technology. The powertrain combination produces a maximum output of 125 kW, peak torque of 252 Nm and combined fuel economy of 6.2 liters/100 km. The new Buick LaCrosse 20T is eligible for the Chinese government’s 50 percent purchase tax cut for vehicles with small-displacement engines.

Enhanced Chassis System

The new Buick LaCrosse has an upgraded chassis system. It comes with GM’s second-generation Continuous Damping Control (CDC). A sensor monitors road conditions 100 times per second to maximize comfort and handling. Younger drivers will appreciate the specially tuned Sport mode, which ensures better handling – especially in cornering.

The optimized MacPherson front suspension in the new Buick LaCrosse has a class-leading decoupled three-link upper suspension structure that independently passes on the load of the springs, bumper blocks and dampers to the body for faster response. A redesigned eight-point full-length sub-frame connects the body using four vibration isolation joints and four enhanced connecting points. 

A multi-link independent rear suspension isolates vibrations while offering sufficient lateral rigidity and stability. An upgraded Electric Power Steering (EPS) system provides precise and highly efficient steering control by boosting the motor power by 39 percent and enhancing transmission efficiency to over 85 percent.
