Interior space is somewhat less than its exterior size would indicate, especially in the rear cargo area, but the cabin offers plenty of storage nooks for smaller items. Passenger space front and rear is very good, even for tall adults.
The entire cabin is lined in high-quality leather, wood, and wool carpeting, which fits the experience you'd expect at the Range Rover Sport's price point. Ride quality can be a bit stiff, but that's the price paid for so much handling and performance.
Wind, road, and engine noise is minimal, though they rise as the speed does, becoming truly noticeable only at extra-legal speeds. As with any vehicle, particularly those with wide tires, some road surfaces can induce tire noise as well.
