Range Rover L405 Information
Explore the standard and long-wheelbase models, diesel, petrol and plug-in-hybrid engines, electronic air suspension and important identifying features of the fourth-generation Range Rover.
The Range Rover L405
The Range Rover L405 was introduced in 2012 as a completely redesigned replacement for the L322. It retained the familiar floating roof, clamshell bonnet, upright glasshouse and split tailgate while adopting smoother bodywork and a more modern interior.
Its most significant structural change was the use of an aluminium-intensive monocoque body. This helped reduce weight considerably compared with the previous generation while maintaining strength, refinement and off-road capability.
The L405 was available in standard and long-wheelbase forms, with trim levels ranging from Vogue and Autobiography to high-performance and ultra-luxurious SVAutobiography models. Diesel, petrol, mild-hybrid and plug-in-hybrid powertrains were offered during production.

The SVAutobiography became the new flagship, combining bespoke luxury detailing with a specially tuned supercharged V8 on suitable versions.
Major facelift and P400e plug-in hybrid
The updated L405 received revised lamps, bumpers, interior screens and controls. The P400e combined a 2.0-litre petrol engine with an electric motor and high-voltage battery.
New straight-six petrol powertrain
The P400 introduced an Ingenium straight-six petrol engine with 48-volt mild-hybrid assistance, replacing the earlier supercharged V6 in suitable markets.
Mild-hybrid diesels join the range
Later vehicles received D300 and D350 straight-six Ingenium diesel engines with 48-volt mild-hybrid technology, replacing earlier V6 and V8 diesel options.
Final editions and end of production
Final models included the Fifty and SVAutobiography Ultimate editions before production gave way to the new Range Rover L460.
Air suspension, Terrain Response and permanent four-wheel drive
The L405 combines independent electronic air suspension, permanent four-wheel drive and advanced Terrain Response systems. Suitable models use a twin-speed transfer gearbox, active rear differential and automatic height adjustment to provide strong capability on road and across difficult terrain.
Range Rover L405 Engines
Engine availability varies by model year and market. Always confirm the complete VIN, engine designation and production period before ordering parts.
Three-Litre Diesel V6
Early lower-output diesel models use the twin-turbo 3.0-litre TDV6. Fuel, turbocharger, EGR, cooling and emissions parts must match the precise engine specification.
Higher-Output Diesel V6
The SDV6 is a higher-output version of the 3.0-litre diesel. It shares some components with the TDV6, but engine-management, turbocharger and emissions parts can differ.
Twin-Turbo Diesel V8
The 4.4-litre SDV8 provides strong torque and refinement. Cooling, turbocharger, fuel, exhaust, transmission and brake components can be specific to this model.
Supercharged Petrol V6
Selected petrol models use a supercharged 3.0-litre V6. Ignition, intake, cooling and exhaust components differ from the diesel and V8 powertrains.
Supercharged Petrol V8
The flagship 5.0-litre supercharged V8 was offered in several outputs. Higher-performance versions can use different brakes, cooling, exhaust and drivetrain components.
Plug-In Hybrid
The P400e combines a 2.0-litre Ingenium petrol engine with an electric motor and high-voltage battery. Charging, cooling, braking and drivetrain parts are specific to the hybrid.
Petrol Straight-Six Mild Hybrid
Later P400 models use a 3.0-litre Ingenium straight-six petrol engine with 48-volt mild-hybrid assistance. Electrical and auxiliary-drive parts are model specific.
Diesel Straight-Six Mild Hybrid
Final-period diesel models use 3.0-litre Ingenium straight-six engines with 48-volt mild-hybrid technology. They differ completely from the earlier V6 and V8 diesels.
Automatic Transmission
L405 models use an eight-speed automatic gearbox, but transmission specification, torque capacity, cooling and service parts vary according to engine and year.
Range Rover L405 Long Wheelbase
The long-wheelbase L405 extends the wheelbase and rear body to provide additional legroom for rear-seat passengers. It was offered with highly equipped Autobiography and SVAutobiography interiors.
