The Land Rover Discovery 3, also known as the LR3 in some markets, is a mid-size luxury SUV that was produced by Land Rover from 2004 to 2009. This generation marked a significant departure from its predecessors, adopting a more modern and refined design while retaining Land Rover's renowned off-road capabilities. The Discovery 3 was built on a unique platform, featuring an independent suspension system with coil springs and a permanent four-wheel drive system with a two-speed transfer case. Power came from a range of gasoline and diesel engines, including a 4.4-liter V8 petrol engine and a 2.7-liter V6 diesel engine. The Discovery 3 offered a luxurious interior with ample space for seven passengers, along with a range of features like leather upholstery, a premium sound system, and a navigation system.

It also incorporated a number of enhancements to the interior and exterior design, further solidifying its position as a desirable luxury SUV.
