The 2015 Buick LaCrosse is a full-size luxury sedan that offers a high degree of comfort, sophistication, and technology. It's available in four trim levels: Base, Leather (1SL), Premium 1 (1SP), and Premium 2 (1SR). Under the hood, there are two powertrain options: a standard 3.6-liter V6 engine with 304 horsepower and a mild-hybrid 2.4-liter four-cylinder engine with an electric motor, providing 182 horsepower (known as eAssist). Both engines are paired with a six-speed automatic transmission. Front-wheel drive is standard, with all-wheel drive available on select V6 models. Key safety features include antilock disc brakes, stability and traction control, and a suite of airbags. Available technologies include forward collision alert, lane departure warning, and Buick’s IntelliLink infotainment system with an 8-inch touchscreen, navigation, Bluetooth connectivity, and smartphone integration for Apple CarPlay and Android Auto. Notable for the 2015 model year, Buick added a standard rearview camera and 4G LTE connectivity with built-in Wi-Fi hotspot.
