Overview
Range Rover Sport L494 — Overview
The Range Rover Sport L494 is the second generation of Land Rover's performance-oriented SUV, launched in 2013 as the successor to the L320.
Built on the aluminium D7u platform shared with the Range Rover L405, the L494 offered significant weight savings and improved dynamics over its predecessor. The engine line-up expanded dramatically over its nine-year production run: early cars offered 3.0-litre V6 diesel, 3.0-litre supercharged V6 petrol, and 5.0-litre supercharged V8 petrol options; a 2016 update introduced the 2.0-litre Ingenium diesel four; the 2018 facelift brought the 2.0-litre Ingenium petrol (P300), the P400e plug-in hybrid, and later the 3.0-litre Ingenium six-cylinder diesel MHEV (D300). The range-topping SVR delivered 575 bhp from its supercharged 5.0-litre V8.

Best & Worst Engines

Best Diesel Overall
448DT 4.4-litre SDV8 — The 4.4-litre V8 diesel (Ford-sourced) is the most robust diesel in the L494 line-up. No catastrophic bottom-end design flaw, no crankshaft bearing failure like the 306DT, and oil cooler leaks are the primary concern — a manageable repair rather than an engine-killer.
“”
Who it's for: buyers who want effortless V8 torque without the V6 diesel's reliability anxiety.

Best Petrol Overall
PT204 2.0-litre Ingenium P300 — The 300 bhp four-cylinder petrol is the most reliable petrol in the L494 line-up. No supercharger cooling system to manage, no V8 timing-chain complexity, and a simpler overall architecture than the V6 and V8 options.
“”
Who it's for: buyers who want petrol reliability without the V6/V8's fuel consumption.

Highest Risk
306DT 3.0-litre V6 Diesel — The AJD V6 diesel suffers from crankshaft bearing failure (tin-aluminium coating fatigue) at 80,000–140,000 miles, often preceded by cold-start knock. A bottom-end rebuild costs £5,500–£7,000; a full reconditioned replacement runs £6,500–£9,500. This is the defining risk of the L494 generation.
“”
Who it's for: only buyers with full service history, 5,000-mile oil changes, and a comprehensive warranty.

Most Expensive Failure
508PS 5.0-litre Supercharged V8 (SVR) — The SVR's 575 bhp V8 is the most expensive engine in the L494 line-up to replace, with reconditioned units costing £5,500–£9,000 supply-only. Timing-chain guide wear and cooling system leaks are the primary risks.
“”
Who it's for: enthusiasts and collectors who accept the premium.

Best Value
204DTA 2.0-litre Ingenium SD4 — The 240 bhp diesel four offers the best balance of performance, economy, and running costs. Post-2019 units are significantly more reliable than the V6 diesel, and the recon cost is substantially lower than the 306DT.
“”
Who it's for: the majority of L494 buyers who want affordable running costs.

Most Overlooked
448DT 4.4-litre SDV8 — Often ignored by buyers who default to the V6 diesel or petrol V8, the 4.4 V8 diesel delivers effortless torque, excellent refinement, and significantly better reliability than the 306DT. It's the diesel that L494 buyers should be considering.
“”
Who it's for: buyers who want diesel economy with V8 refinement.

Range Rover Sport L494 — Ownership Economics
The L494 rule
A £6,500–£9,500 306DT recon against a £10,000–£14,000 early L494 sits at 46–95% of the car's value. On a sub-£12,000 L494, that brushes our 60% Land Rover threshold — we'll honestly tell you to walk away. Against a well-kept £18,000+ example, the same recon drops to a routine 36–53% — a repair decision, not a financial one. Value the car first.
Key Takeaways
Which L494 Costs Least To Own?
PT204 2.0-litre petrol — cheapest recon, simplest architecture.
Which L494 Costs Most To Own?
306DT V6 diesel — crankshaft bearing failure is catastrophic and expensive.
Which L494 Is Best Value?
448DT 4.4-litre SDV8 — V8 refinement without the V6 diesel's catastrophic risk.
