As an AI language model, I don't have access to the latest information but I can provide some general information about the Buick LaCrosse CSX based on its previous model years. The Buick LaCrosse CSX is a mid-sized luxury sedan manufactured by Buick. The CSX model was introduced for the 2011 model year and was a hotted-up version of the LaCrosse. It featured a 3.6-liter V6 engine with a six-speed automatic transmission, producing 280 horsepower and 259 pound-feet of torque. The CSX featured sportier exterior styling with a black grille, 18-inch chrome wheels, and a rear spoiler. The interior was more luxurious, with leather seats, a sunroof, and a touchscreen audio system. The CSX also featured sport-tuned suspension and steering, making it a more engaging drive compared to the standard LaCrosse.
