SECTION 07
Comparison Hub – Head-to-Head Verdicts
The comparisons Land Rover buyers actually want — generation vs generation, engine vs engine, model vs model. Honest, data-backed, and built for real-world decision-making.
- 01Discovery 4 vs Discovery 5
Which generation to buy — the verdict on reliability, running costs, and long-term value. The Discovery 5 benefits from revised Ingenium engines; the Discovery 4 needs proven oil-interval history.
Read the verdict → - 02L405 vs L460 Range Rover
Is the extra outlay worth it? We compare ownership costs, reliability, and resale value. The L405 offers the widest value-to-cost margin; the L460 is safer but at a higher entry price.
Read the verdict → - 03TDV6 vs SDV6
What's the real difference? Performance, reliability, and replacement costs compared side-by-side. Both share the 306DT crankshaft bearing risk — the difference is power delivery and host vehicle.
Read the verdict → - 04Ingenium vs TDV6
Which should you buy? We compare fuel economy, reliability, and long-term ownership costs. The post-2019 Ingenium is the safer bet; the TDV6 delivers more power but carries real bearing risk.
Read the verdict → - 05Defender vs Discovery
The practical ownership comparison — space, capability, running costs, and everyday usability. The Defender holds value better; the Discovery offers more seats and family practicality.
Read the verdict → - 06Range Rover Sport vs Discovery
Ownership costs compared — which SUV offers better value for money over 3-5 years? Both share engines and platforms; choose based on refinement versus family practicality.

EXAMPLE VERDICT – LAND ROVER
Discovery
BEST GENERATION
Discovery 5, for build quality and the revised post-2019 Ingenium.
WORST GENERATION
Discovery 3/4 on the 2.7 TDV6, where oil pump failure can take the engine out with little warning.
MOST RELIABLE ENGINE ACROSS THE RANGE
The 4.4 SDV8 — high replacement cost, but a genuinely low failure rate.
HIGHEST RISK
The 3.0 TDV6/SDV6's crankshaft bearing failure, which is largely unrepairable once it starts.
BEST USED BUY
A Discovery 4 SDV6 with full service history and proven oil-interval discipline.
