What’s the Difference Between the Vogue 4.4 SDV8 and 5.0 Supercharged V8?

Range Rover engine replacement

Comparing the Range Rover Vogue 4.4 SDV8 vs 5.0 V8 comes down to a choice between diesel torque and efficiency versus petrol refinement and outright performance, two very different approaches to powering the same full-size luxury SUV. Both units count among the most popular Range Rover Vogue engine options fitted to L405-generation models, and each carries its own considerations around running costs, reliability, and engine replacement pricing. At Range Rover Engine Specialist in Grays, UK, we supply and fit both Range Rover engine variants weekly, and this guide breaks down real differences, engine codes, specifications, and common faults, all backed by no upfront charges and no deposit required.

Range Rover Vogue 4.4 SDV8 vs 5.0 V8: The Overview

At the highest level, the 4.4 SDV8 is a twin-turbo diesel V8, engine code 368DT, built for strong low-end torque and better fuel economy over long distances. The 5.0-litre supercharged V8, engine code AJ133, is a petrol unit built for immediate throttle response and outright power, particularly in Autobiography and SVAutobiography models. Choosing between the Range Rover Vogue 4.4 SDV8 vs 5.0 V8 typically depends on whether you prioritise towing and touring efficiency or want the most engaging driving experience the full-size Range Rover can offer, since both are well proven in UK ownership.

Engine Codes and Core Specifications

The 4.4 SDV8, engine code 368DT, uses twin sequential turbochargers to produce between 335 and 339 bhp with 740 Nm of torque, giving strong pulling power from low engine speeds. The 5.0 supercharged V8, engine code AJ133, uses a Roots-type supercharger for instant response without turbo lag, producing between 503 and 557 bhp depending on tune, with SVAutobiography Dynamic models sitting at the top of the range. Both engines use an aluminium block to help manage the considerable weight of the full-size Range Rover, though the supercharged unit carries a noticeably higher parts and rebuild complexity than the diesel.

Performance and Everyday Driving Differences

The 4.4 SDV8 delivers its peak torque low in the rev range, making it feel effortless when towing or cruising at motorway speeds, with 0-60mph typically around 6.5 seconds. The 5.0 supercharged V8 is noticeably quicker, with SVAutobiography Dynamic models capable of around 5.1 seconds to 60mph, and delivers a distinctive supercharger whine that many owners find appealing. Fuel economy strongly favours the SDV8 diesel, particularly on longer journeys, while the supercharged petrol trades efficiency for character and outright pace, an important consideration before committing to any engine rebuild or replacement decision.

Common Problems and Solutions: SDV8 vs Supercharged V8

The 368DT SDV8 diesel is known for injector seal leaks and occasional turbo actuator wear on higher-mileage examples, both addressed with correct replacement parts during a service or rebuild. The AJ133 supercharged V8 can develop timing chain guide wear and supercharger coupling failure, producing a distinctive rattle or whine that should be investigated promptly. Both engines respond well to proactive maintenance, and catching either fault early significantly reduces the risk of it escalating into a full engine rebuild with a considerably higher bill than early intervention would have required.

Reconditioned Engines vs Used Engines for Either Unit

Whichever engine your Vogue uses, understanding reconditioned engines vs used engines matters given how much load both the SDV8 and the supercharged V8 carry throughout their life. A used engine removed from a donor vehicle carries the same wear history as that car, a real concern on the supercharger coupling or turbo units specifically. A reconditioned JLR engine is fully stripped, rebuilt with new bearings, seals, gaskets, and often a new timing chain or turbo actuator, giving genuine peace of mind. For most owners, the safer long-term choice is to buy a reconditioned unit rather than risk a used engine of uncertain remaining lifespan.

Running Costs and Engine Replacement Pricing

Engine replacement costs in UK garages for the 4.4 SDV8 typically range from £4,200 to £6,000 for supply and fit, while the 5.0 supercharged V8 sits considerably higher, from £6,800 to £9,600, reflecting its greater parts complexity and labour requirements. Labour alone can add £900 to £1,600 depending on model year and whether ancillary parts such as the turbo or supercharger coupling also need attention. Servicing costs also differ, with the supercharged petrol typically requiring more frequent oil changes given its higher operating demands compared with the diesel SDV8.
