About 2013 Buick LaCrosse The LaCrosse luxury sedan features a sculpted design, craftsmanship, premium materials and advanced technologies that have helped change consumers' perceptions about Buick. This 2013 premium Buick sedan is available in five trim levels, including LaCrosse, Leather, Premium I, Premium II and Touring. Designed to represent modern elegance, the 2013 LaCrosse exterior and interior are a balance of contrasts: The outside is characterized by taut lines with sensuous accents and surfaces. Inside, a flowing, uninterrupted design theme wraps around the instrument and door panels. It includes smoked chrome accents, warm wood, first-class leather and materials combined with ice blue ambient lighting to create an inviting environment. Meticulous attention to detail includes tight gap tolerances, analog instrument cluster, chrome offset by dark woodgrain accents, and contrasting stitching on the instrument panel. Buick's signature QuietTuning -- a Buick-exclusive engineering process to reduce, block and absorb interior noise -- provides a distraction-free cabin. LaCrosse offers two powertrains: an Ecotec 2.4L engine with eAssist light electrification technology that achieves 36 mpg on the highway; or an efficient 3.6L direct-injected V-6. A next-generation six-speed transmission is paired with the Ecotec 2.4L engine with eAssist. LaCrosse is available in front-wheel drive and all-wheel drive. Buick's easy-to-use IntelliLink color touch radio is now also available in combination with GPS-enabled navigation for 2013. Buick IntelliLink uses Bluetooth or USB to connect the driver's smartphone -- via voice activation and steering wheel-mounted controls -- to an 8-inch, high-resolution, full-color touch-screen display radio.
