The 2018 Subaru Legacy is available in either 2.5i or 3.6R models, with the former available in base, Premium, Sport and Limited trims, while the 3.6R comes only in Limited configuration. Two engines are available. In Legacy 2.5i models, the engine is a 2.5L 4-cylinder horizontally opposed "boxer" that makes 175 horsepower and 174 pound-feet of torque. The larger, optional engine found in the Legacy 3.6R Limited is a 3.6L 6-cylinder boxer engine capable of 256 horsepower and 247 pound-feet of torque. The engine maintains at least 225 pound-feet from 2,000, to 6,000 rpm, giving the 3.6R Limited plenty of smooth power on demand. Subaru's Lineartronic continuously variable transmission is standard across the model range. Subaru's trademark symmetrical all-wheel drive is standard on all models, and the Legacy's front MacPherson struts and double-wishbone rear suspension provide a compliant but agile ride. The base Legacy 2.5i includes plenty of standard features, such as 17-inch steel wheels, automatic projector-beam halogen headlights, side ground effects, air conditioning, 6-way adjustable driver's seat, steering wheel-mounted cruise and audio controls, a USB charging port, hill assist and Bluetooth hands-free connectivity. The infotainment system provides AM/FM stereo and HD Radio functionality, with a multi-function 6.2-inch touchscreen display, smartphone integration and more. Premium models add 17-inch alloy wheels, fog lights, a rear-vision camera, dual-zone automatic climate control, a 10-way power adjustable driver's seat, a leather wrapped steering wheel, a 7-inch touchscreen infotainment system and the All-Weather Package, which features heated front seats, heated side mirrors and a windshield wiper de-icer. Legacy Sport models come equipped with 18-inch alloy wheels, fog lights, satin-finish mirrors with integrated turn signals, a power sunroof, keyless entry and ignition, an auto-dimming rearview mirror and carbon fiber-patterned interior appointments. Limited models in both 2.5i and 3.6R come standard with perforated leather upholstery with heated front and rear seating, 2-position memory for the 10-way power adjustable driver's seat, along with a 4-way power passenger seat. Rear-seat air conditioning vents and a premium infotainment system with 12-speaker harman/kardon audio package are also included. Options on the Premium trim include the power sunroof, voice-activated GPS navigation and blind spot detection, while Subaru's excellent EyeSight driver assist technology is available on the Premium, Sport and Limited.
