The Land Rover Discovery 3, also known as the LR3 in some markets, is a mid-size luxury SUV that was manufactured by Land Rover from 2004 to 2009. It represented a significant departure from its predecessor, the Discovery 2, featuring a completely redesigned platform and a more refined interior. The Discovery 3 was built on the Ford platform, which also underpinned several other Ford and Jaguar models. This shared platform allowed for a more sophisticated drivetrain and suspension system, offering improved on-road handling and comfort while maintaining the off-road prowess expected from Land Rover vehicles. Its distinctive design, characterized by the sloping roofline and the large clamshell tailgate, was both stylish and functional. The interior was spacious and well-appointed, offering ample seating for seven passengers and a generous cargo area.

The Discovery 3 was available with a range of powerful and efficient engines, including a 4.0-liter naturally aspirated V8 and a 2.7-liter turbodiesel V6. Both engines were mated to a six-speed automatic transmission, providing smooth and responsive acceleration. The Discovery 3's permanent four-wheel drive system, featuring a two-speed transfer case and Terrain Response system, provided excellent traction and off-road capabilities. The Terrain Response system allowed the driver to optimize the vehicle's performance for different terrains, such as sand, mud, and rocks. The Discovery 3 was praised for its versatility, combining luxurious comfort with genuine off-road capability, making it a popular choice for families and adventure seekers alike.
