The 2015 Land Rover Discovery HSE was offered as both the Discovery Sport HSE and the LR4 HSE, with the Discovery Sport being the newer, more compact model. Both featured luxury appointments such as leather upholstery, heated and power-adjustable seats, and advanced infotainment systems, along with standard all-wheel drive and a focus on off-road capability. Key differences include engine type, standard seating configuration (5-seat for Sport, standard 7-seat for LR4), and specific features like the panoramic sunroof in the Sport.
