The New LaCrosse does not have an underbody guard. This vehicle is a 5-seater, 4-door mid-size sedan under SAIC-GM, with exterior dimensions of 5026mm in length, 1866mm in width, and 1459mm in height, a wheelbase of 2905mm, a fuel tank capacity of 55 liters, and a trunk capacity of 523 liters. The car is equipped with 1.5L and 2.0L turbocharged engines and an automatic transmission, delivering a maximum power of 124 kW at 5600 rpm and a maximum torque of 250 Nm. It features a MacPherson independent front suspension, a multi-link independent rear suspension, and a tire pressure monitoring system.

As a car owner, I previously drove the new LaCrosse, and the underbody protection plates on that car were well-designed, usually coming as standard in higher trim models. Buick typically adds protective plates to key areas, such as under the engine and transmission, using metal or plastic materials to shield against gravel and water. In my driving experience, these plates effectively reduce road noise and prevent scrapes and damage, providing extra peace of mind especially during long trips or on rough roads. If unsure, I recommend checking the official specifications or consulting the dealership salesperson when purchasing a car. During regular maintenance, I always have the technician inspect the fasteners—tightening them if loose and replacing damaged plates promptly to avoid minor issues turning into major repairs. Though small, these plates significantly impact the vehicle's overall lifespan and driving comfort, so they shouldn't be overlooked.

I'm passionate about car modifications, and the chassis protection system of the new LaCrosse is quite impressive, with most models equipped with underbody panels. This design not only safeguards the oil pan and drivetrain components but also enhances body rigidity. During my test drive, I felt a noticeably smoother ride. These panels are typically made of composite materials or steel, offering excellent resistance to scratches and impacts, providing extra peace of mind for off-road enthusiasts. To confirm if your car has them, check the vehicle manual or official website specifications. With these panels, you won't need to worry about stone chips or winter road salt corrosion. Installing reinforced underbody panels is also straightforward—I've recommended this to friends, as it significantly extends the lifespan of major components.

After years of repairing cars, I often see the new LaCrosse coming to the shop. Most models come with underbody shields, made of plastic or metal, to protect the engine bottom. In standard maintenance, these shields prevent dust and moisture, avoiding minor issues like oil pipe damage. Common faults include loose bolts or impact deformation, easily spotted during inspections using a lift. If the original shield is missing, aftermarket installation is straightforward and affordable. Shields save on major repair costs, so always check the configuration when buying a car to avoid future hassles.

Choosing the New LaCrosse as a family car, I prioritize safety, where the underbody protection plate plays a crucial role in standard configurations. It shields against road debris, safeguards the transmission and fluid systems, and reduces the risk of sudden malfunctions. When traveling with kids, the protection plate gives me peace of mind when navigating bumpy roads. Configuration may vary across different trims, so checking the dealership list or online resources for confirmation is advisable. For maintenance, inspecting the integrity of the protection plate during each service helps prolong the vehicle's overall lifespan.
