Range Rover Sport vs rivals: A used luxury 4WD worth considering
Used car buyers looking at the Range Rover Sport 2005 to 2013 model years often face a stark choice between capable performance and expensive repairs. This era of the vehicle, known internally as the L320, sits in a crowded market competing directly with the BMW X5, Mercedes-Benz ML, and Porsche Cayenne. The Sport was designed to bridge the gap between luxury and off-road toughness, but its reputation is complicated by a history of engineering quirks.
Beneath the high-end interior materials and Range Rover badging, the L320 was built on the same platform as the Land Rover Discovery 3. This semi-monocoque construction provided the base for a vehicle that could handle difficult terrain, though it was not a dedicated off-roader. The series launched in Australia in 2005 with a range of mechanical packages to suit different needs.
The lineup initially included a 2.7-litre turbo-diesel V6 producing 140kW paired with a six-speed automatic transmission. This model was notable for featuring a proper two-speed transfer-case and permanent four-wheel drive. Buyers could also opt for a 4.4-litre petrol V8 with 220kW or the high-performance 4.2-litre supercharged V8, which offered 287kW. All V8 variants included a locking rear differential and a six-speed auto. A year after launch, a 3.6-litre twin-turbo diesel V8 joined the lineup with 200kW of power.

Even the base models included features like 18-inch alloy wheels, dual-zone climate control, cruise control, and leather upholstery. Higher trims added upgrades such as bi-xenon headlights and rear parking sensors, while the supercharged versions received 20-inch wheels, Brembo brakes, and memory seats.
Reliability Concerns
The driving experience of the L320 is frequently described as a blend of high-speed stability and comfort, with capable off-road manners. However, the vehicle’s reputation for longevity is marred by a litany of mechanical and electrical issues that have surfaced over the years. This makes the car a significant gamble for potential buyers.
The most serious concerns involve the 2.7 and 3.0-litre V6 turbo-diesels. These engines have a history of failing due to problems with the bottom end bearings. Symptoms often include a knocking noise that increases with engine load and a low oil pressure warning. Once these signs appear, there is a very short window—seconds—to pull over and shut off the engine, or the crankshaft can fail completely. A known design flaw in the oil pump assembly of early engines could also cause the timing belt to jump, resulting in immediate engine failure. Even the turbochargers on the 2.7-litre unit were prone to internal wear, indicated by white smoke from the exhaust.
The 5.0-litre supercharged V8 was not immune, often developing a ticking or rattling noise traced to the timing chain tensioner. While an improved design arrived in 2012, earlier models required expensive replacements. The air suspension system has also been a frequent point of failure, with compressors failing to maintain ride height or leaking air, sometimes requiring the replacement of the suspension units themselves.

Electrical and safety issues were widespread. Early models faced recalls regarding the transmission refusing to select Park, ABS sensors chafing on wheel assemblies, and faulty crank angle sensors that could stop the engine. Perhaps the most alarming recall involved V6 turbo-diesels between 2004 and 2009, where a vacuum system failure could lead to a total loss of braking performance.
Purchasing Advice
Later-built examples are generally considered more reliable because they incorporated fixes for known defects. However, the turbo-diesel variants in any form are widely advised to be avoided due to their susceptibility to catastrophic engine failure. A high-mileage turbo-diesel can be found for under $10,000, but the risk of expensive repairs remains high.
Those interested in a petrol V8 have a slightly better chance of longevity, though they are not immune to air suspension failures. The current market reflects these risks, with listings for the L320 series showing a predominance of diesel models. While specialist workshops and a robust aftermarket parts industry exist to service these vehicles, finding one that has not required significant repair work is a challenge. The decision to buy one comes down to accepting the potential for mechanical drama in exchange for the driving experience.
