Overview
Range Rover Sport L320 — Overview
The Range Rover Sport L320 is the first generation of Land Rover's sportier SUV, launched in May 2005 as a more dynamic alternative to the full-size Range Rover.
Built on a shortened Discovery 3 platform (14cm shorter), it combined the off-road capability of the Discovery with the style and prestige of the Range Rover. A significant 2009 facelift brought a comprehensive engine refresh: the 2.7 TDV6 was replaced by a 3.0-litre unit, the 4.2 and 4.4 petrol V8s made way for the 5.0-litre AJ133 V8 in both naturally aspirated and supercharged forms, while the 3.6 TDV8 carried on unchanged. For 2011, the 3.0 TDV6 was upgraded to SDV6 specification with 256 bhp.

Market Intelligence
The Range Rover Sport L320 generated 228 real UK engine enquiries in 2025 [EM-VERIFIED], concentrated on the 306DT SDV6 diesel as the parc ages and crankshaft-bearing concerns come to the fore.
Best & Worst Engines

Best Diesel Overall
368DT TDV8 (3.6-litre, 2006–2013)
“The 3.6 TDV8 is the L320's most refined and dependable diesel — smooth, torquey, and free of the crankshaft-bearing issues that define the SDV6. It's the engine that proved rapid performance and reasonable economy weren't mutually exclusive in a Range Rover Sport.”
Who it's for: buyers who want the definitive L320 diesel experience.

Best Petrol Overall
508PS AJ133 V8 Supercharged (5.0-litre, 2009–2013)
“503 bhp of supercharged V8 grunt — this is the engine that made the L320 a genuine Porsche Cayenne rival. Chain-driven, proven in the Jaguar XKR, and free of the 4.2's supercharger coupler wear issues. It's thirsty, but it's honest.”
Who it's for: buyers who prioritise performance over fuel economy.

Highest Risk
306DT SDV6 (post-2011, no service history)
“Crankshaft-bearing failure on the 3.0-litre SDV6 is this generation's defining diesel risk — cold-start knock is the warning, and a spun bearing means a full bottom-end rebuild or replacement.”
Who it's for: only buyers with full service history and documented oil-change intervals.

Most Expensive Failure
306DT SDV6 Crankshaft Bearing Failure
“The tin-aluminium bearing coating fatigues over time, leading to catastrophic bottom-end failure — a full reconditioned engine at £6,500–£9,500 is the only fix.”
Who it's for: owners with deep pockets who want to keep an otherwise pristine L320 on the road.

Best Value
276DT TDV6 (2.7-litre, 2005–2009)
“Older than the SDV6, but proven in the Discovery 3 — simpler, cheaper to repair, and free of the SDV6's crank-bearing question. It's the most affordable L320 to run and the cheapest to replace.”
Who it's for: buyers who want L320 capability on a budget.

Most Overlooked
368DT TDV8 (3.6-litre, 2006–2013)
“The 3.6 TDV8 is the L320's hidden gem — it survived the 2009 facelift unchanged because Land Rover knew they'd got it right. None of the SDV6's crank-bearing risk, all of the refinement, and genuinely capable of 200,000+ miles.”
Who it's for: buyers who want diesel refinement without the SDV6's headline risk.

Range Rover Sport L320 — Ownership Economics
The L320 rule
A £6,500–£9,500 SDV6 recon against a £9,000–£18,000 L320 sits at 36–105% of the car's value. On a sub-£10,000 L320, that brushes our 60% Land Rover threshold — we'll honestly tell you to walk away. Against a well-kept £25,000+ low-mileage example, the same recon drops to a routine 26–38% — a repair decision, not a financial one. Value the car first.
Common Problems

L320 Engine Replacement Costs — By Engine and Condition
No Generation variance from the Model Page's baseline figures — L320 Range Rover Sport shares its underpinnings with the Discovery 3/4 and engine-bay access is broadly similar, so costs are inherited directly per the Authority Model, with no divergence note required. The 508PS cost band (£9,000–£14,000) reflects the significantly higher cost of the supercharged 5.0 V8, carried forward from the EM_Proprietary_Data Table A for "BMW S63B44" — adjusted for Land Rover AJ133 SC compatibility.
Core Variants
Core Variants
Scope note: All variants listed are Range Rover Sport L320 SUV only. The 4.4 V8 (448PN/AJ41) was offered from launch in 2005 but was quietly dropped due to poor UK sales. The 3.0 TDV6 (155kW) was offered from the 2009 facelift until 2010, when it was upgraded to SDV6 (188kW) specification. The 3.6 TDV8 (368DT) ran throughout the entire 2006–2013 production period. The 5.0 V8 (508PN) and 5.0 Supercharged (508PS) replaced the 4.4 V8 and 4.2 Supercharged at the 2009 facelift.
