★★★★★
Our Verdict:
Now the bargain-bin Range Rover — and the danger zone. Values have fallen to where one V6 diesel failure writes the car off. The TDV8 is the survivor's choice; any 2.7 without oil-pump history is a gamble, not a purchase.

🏁 #3 Most-Enquired Model (L494, 308 enquiries) [EM-VERIFIED]
One-line verdict:
The Range Rover Sport shares every engine with the full-size car but none of the gentle life — it's driven harder, traded cheaper, and sits closer to the repair-or-scrap line than any other Range Rover, which is exactly why the engine question matters more here than anywhere else.

Insights from the data:
Interesting insight: All three Sport generations rank among our most-enquired models simultaneously [EM-VERIFIED] — no other Land Rover family does that. The Sport generates engine decisions at every price point from £5,000 to £120,000 at once.
L320 enquiries mirror the Freelander pattern — repair-vs-scrap crossroads — while L494 enquiries mirror the Discovery 4: failure-driven, high-stakes, paperwork-dependent. One model page, two completely different reader mindsets. (Editorial synthesis — specialist sense-check before publishing.)
Sport-fitted 306DT engines appear in our failure enquiries at lower mileages than the same engine in the Discovery — consistent with harder use, and the reason we weight service history even more heavily on this model. (Editorial synthesis.)
Editorial Pull-Quote
The One Thing We'd Tell Every Range Rover Sport Buyer
“If you buy one Range Rover Sport based on this page, make it a late L494 SDV8 or a 2021+ D350 — and treat any sub-£15,000 Sport on a V6 diesel as what it is: an engine gamble with a car attached. Price the gamble, not the car.”

Buyer Profile
Rating
Our Verdict
Family Buyer
★★★★★
★★★★★
An L494 is a superb family car with genuine pace — the full-size Range Rover's substance at a real discount. Buy the engine, not the wheels.
Daily Commuter
★★★★★
★★★★★
Short runs are how Sport diesels die — DPF regens interrupted, oil diluted, crank bearings worked cold. Motorway commuters only; town commuters want the P400e or P440e.
Towing & Working Use
★★★★★
★★★★★
3,500kg with the SDV8 or D350 barely noticing — among the best tow cars money can buy.
Budget Owner
★★★★★
★★★★★
The single riskiest budget buy on this site. A £9,000 L320 carries engines whose failure costs more than the car — if the fund can't absorb a total loss, it can't absorb this car.
Performance Enthusiast
★★★★★
★★★★★
The SVR is a genuine event and the AJ133 is stronger than its whine suggests — budget supercharger and chain-guide attention as a running cost, not a surprise.

Range Rover Sport Frequently Asked Questions
1How much does a Range Rover Sport engine replacement cost in the UK?
Reconditioned units run £3,000–£16,000 supply only depending on generation and engine [EM-QUOTE] — the volume SDV6 sits at £6,500–£9,500, the SDV8 at £8,000–£12,000. Fitting adds £780–£2,100. Use our calculator for a personalised figure.
2Which Range Rover Sport engine is the most reliable?
The 4.4 SDV8 (448DT) — the lowest failure-enquiry rate of any big engine in our data. Among current engines, the AJ20D6 D300/D350 is proving similarly strong.
3Which Range Rover Sport engine should I avoid?
The 2.7 TDV6 (276DT) without oil-pump history and the 3.0 TDV6/SDV6 (306DT) without documented oil intervals. Both fail catastrophically; on L320 values, both usually total the car.
4Is the Range Rover Sport SDV6 engine reliable?
It's the range's defining risk: crankshaft bearing failure at higher mileages, announced by cold-start knock. Sports show it earlier than Discoverys in our patterns — harder lives. Impeccable oil history changes the odds dramatically. Use our diagnostic calculator if yours is knocking.
5Is it worth replacing a Range Rover Sport engine?
Generation decides. L461: always . L494: usually , marginal on the cheapest early cars ⚠️. L320: frequently for a recon — a used engine or walking away is often the honest answer. Use the Ownership Decision Tool for your car.
6Which Range Rover Sport should I buy?
A late L494 SDV8 or 2021+ D350 for the sweet spot; an L461 D350 if buying nearly new; an L320 TDV8 only as an informed enthusiast purchase with a contingency fund.
7How do I find my Range Rover Sport engine code?
On the VIN plate and vehicle documentation; block stampings vary by engine family. Or tell us your variant and year (SDV6, SDV8, D350, P530) and we'll identify it.
8Range Rover Sport vs Range Rover — which is more reliable?
Same engines, different lives. The Sport is driven harder and our failure enquiries reflect it — same failure modes, earlier mileages. The full-size car costs more to buy and less per surprise. Buy on engine and history, not badge. Read the full head-to-head →
