The 2017 Land Rover Discovery is all-new. Available engines include a supercharged V6 that makes 340 horsepower and a turbocharged V6 diesel with 254 hp. An eight-speed automatic is the only transmission offered, but shoppers can add a single-speed transfer case for better on-road performance or a two-speed transfer case for increased off-road capabilities. An available low-speed crawl mode functions much like a cruise control system but is specifically tailored for off-road use, allowing the driver to concentrate solely on steering.
