The flagship SUV has received new LED headlights, more comfortable seats and JLR's most advanced infotainment system yet.

Land Rover has announced a long list of Range Rover upgrades for the 2018 model year, followed by a plug-in hybrid edition for 2019.The flagship SUV is offered with more comfortable front seats, built around a new frame that supports 24-way adjustment. Foam padding is wider and plusher than the basic seats, while the armrests are heated.

Drivers are treated to Jaguar Land Rover's most advanced infotainment system yet, known as InControl Touch Pro Duo, combining two 10-inch touchscreens on the center console. Gesture control can be used to deploy the sunblind.

Occupants no longer have to fumble for seat controls, as all functions -- including 25 hot-stone massage programs -- can be accessed via a dedicated smartphone app. 

Engineers have increased engine output for the SVAutobiography Dynamic package, delivering 557 horsepower for a zero-to-60 mph sprint in 5.1 seconds. The most powerful production Range Rover doesn't come cheap, with prices starting at $177,200 for the standard wheelbase or $207,900 for the stretched variant.

For customers seeking fuel efficiency or a quieter commute, the P400e plug-in hybrid powertrain pairs a 2.0-liter Ingenium engine and a single electric motor for a combined 398 horsepower and 472 pound-feet of torque. The PHEV is expected to drive for up to 31 miles on battery power alone. The Range Rover Sport is also available with the plug-in setup. 

The company has not announced pricing details for the hybrid package.
