A new family of 3.0-litre straight-six Ingenium diesel engines and a range of special editions including the Westminster, Westminster Black Edition and an SVAutobiography Dynamic Black have joined the recently announced Range Rover Fifty celebratory model.

The latest generation of straight-six Ingenium diesel engines, incorporating 48V Mild Hybrid Electric Vehicle (MHEV) technology for reduced fuel consumption and heightened refinement, has been developed in-house. It is available in 296 bhp (221kW) and 345 bhp (258kW) outputs.

The new Westminster Edition is based on the Vogue model and available with a choice of both diesel and plug-in hybrid electric power. Unique for the UK, Privacy Glass and Atlas exterior accents, 21-inch Diamond Turned Alloy Wheels set it apart on the outside and the new model is available in a range of solid, metallic and Premium Metallic finishes. Inside, Grand Black Veneers combine with a Suedecloth Headlining, a Sliding Panoramic Roof, Softclose Doors. The P400e comes with a 19-speaker Meridian Surround sound system  as standard.

The new Westminster Black Edition adds the Black Exterior Pack and customers are able to choose from three wheels ranging from a 21-inch nine-spoke design to a distinctive 22-inch Gloss Black nine split-spoke design. In addition, the new Range Rover SVAutobiography Dynamic Black provides a fresh take on the distinctive SVAutobiography Dynamic, from the specialists at Land Rover SV.

The new special edition models join the limited edition Range Rover Fifty, which was revealed last month and celebrates the 50th anniversary of Land Rover’s luxury SUV family. Only 1,970 of the Fifty models will be produced, to mark the year of its debut five decades ago.

Enhancements across the rest of the Range Rover line-up include the latest connected features, with Apple CarPlay and Android Auto offered as standard across the range for seamless smartphone integration. Up to eight 4G Wi-Fi connections are available.

The Range Rover features safety technologies, including; Lane Departure Warning, Emergency Braking, and Cruise Control with Speed Limiter all standard across the model range. Adaptive Cruise Control is also available.

The new Cabin Air Ionisation with PM2.5 from Nanoe, filters harmful particulates in the cabin, improving air quality for the driver and passengers.

The PM2.5 system in the Range Rover is controlled using a soft button within the infotainment, named ‛Purify’. This initiates the recirculation function, cleaning the air and removing small particulates less than 2.5 micrometres in size that are harmful to health.

New engines

The latest Ingenium diesel engines are based around Jaguar Land Rover’s modular aluminium engine architecture, the new in-line diesel engines are claimed to be smoother and more refined than the previous generation and feature 48V mild hybrid technology to meet the most stringent global emissions regulations.

These include the Real Driving Emissions Step 2 (RDE2) standards, which govern nitrogen oxide (NOx) emissions, making the new Range Rover among the first full-sized luxury and performance SUVs in the world to be available with RDE2-certified diesels. The engines deliver improved responses by harvesting and storing energy generated during deceleration and intelligently redeploying it to assist the engine when accelerating.

The new mild-hybrid 3.0-litre D300 Ingenium diesel is capable of up to 33.0mpg (8.6l/100km) on the WLTP test cycle, emitting as little as 225g/km CO₂. The more powerful D350 achieves up to 30.8mpg (9.2l/100km) with CO₂ emissions of 241g/km on the WLTP cycle. As a result, the new diesel is claimed to provide superior performance to the previous V8 with the efficiency and weight of a six-cylinder design.

Nick Rogers, Executive Director Product Engineering, Jaguar Land Rover, said: “Our family of clean, refined and efficient Ingenium engines has evolved and expanded to give our customers an even greater choice of in-line four and six-cylinder petrols and diesels. Across the Range Rover family, the application of both mild and plug-in hybrid electric technologies provides the perfect blend of performance and efficiency, making Range Rover one of the first full-sized luxury SUVs in the world to be available with RDE2-certified diesel engines.”

The new engine range comprises:

Diesel:

• D300 – 296 bhp (221kW), 3.0-litre six cylinder diesel MHEV, 479 ft lb of torque at 1,500-2,500rpm
• D350 – 345 bhp (257kW), 3.0-litre six cylinder diesel MHEV, 516 ft lb of torque at 1,500-3,000rpm

Petrol:

• P400 – 395 bhp (294kW), 3.0-litre six-cylinder petrol, with 406 ft lb of torque at 2,000-5,000rpm
• P400e – 398 bhp (297kW), 2.0-litre four-cylinder petrol PHEV, 472 ft lb of torque at 1,500-4,000rpm
• P525 – 518 bhp (386kW), 5.0-litre V8 Supercharged, 461 ft lb of torque at 2,500-5,500rpm
• P565 – 557 bhp (415kW), 5.0-litre V8 Supercharged, 516 ft lb of torque at 3,500-5,000rpm

The P400e is the most efficient version of the new Range Rover. With a fully electric, zero-emissions range of 25 miles (40km), the P400e combines an advanced 296 bhp (221kW) four-cylinder Ingenium petrol engine with a 141 bhp (105kW) electric motor. Powered by a 13.1kWh lithium-ion battery, the P400e delivers CO₂ emissions of just 75g/km and fuel economy of up to 84.8mpg (3.3l/100km) on the WLTP combined cycle.

The standard Mode 3 charging cable significantly reduces charging times for the P400e, with a full charge taking under three hours, compared to 7.5 hours when using a Mode 2 charging cable.
