Range Rover new mild-hybrid diesel engines

48-volt assisted straight-sixes replace the old diesel V8s.

The Range Rover (the big one, for royalty and film stars) and Range Rover Sport (slightly smaller, mostly for Premiership footballers) have been given a new 48-volt six-cylinder diesel engine to replace their aged V8 diesels.

3.0 straight-six mild-hybrid

The new 3.0-litre inline-six diesel engines are based on the same components as the four-cylinder Ingenium engines and come in either 300hp or 350hp forms. Both get 48-volt mild-hybrid assistance which reduces their fuel consumption, and which makes them far more economical than the old 4.4-litre TDV8 engine (which was based on old Ford tech).

These new six-cylinder units are among the first to be tested to the new RDE2 real-world emissions standards, to ensure that their emissions of harmful NOX are as low as can possibly be. In the full-size Range Rover, the D300 Ingenium diesel is capable of up to 33mpg (8.6 litres/100km) on the WLTP test cycle, emitting 225g/km CO2. The more powerful D350 achieves up to 30.8mpg (9.2 litres/100km) with CO2 emissions of 241g/km on the WLTP cycle. The D300 has 650Nm of torque, while the D350 has a whopping 700Nm.

One of the first with RDE2 approval

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 two engines join the existing hybrid Range Rover and Range Rover Sport lineup, which includes the P400e plug-in hybrid, which combines 404hp from a 3.0-litre inline-six petrol engine and an electric motor, and which can go up to 41km on just the battery, depending on the model. Emissions are as low as 75g/km and economy peaks at 88mpg (3.2 litres/100km).

New trim options

The Range Rover Sport can also be had with a 300hp 2.0-litre turbo petrol engine, and both it and the Range Rover still offer the supercharged 5.0-litre V8 petrol engine (with up to 575hp) for those who just don't care about fuel economy nor tax costs.

The Sport is also getting some new trim lines, including HSE Silver, HSE Dynamic Black and SVR Carbon Edition while the Range Rover gets a new Westminster Edition, which includes a Westminster Black version that rocks a set of 22-inch wheels.

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 and up to eight 4G Wi-Fi connections. There's also a new 'purify' function for the air conditioning, which initiates the recirculation function, cleaning the air and removing small particulates less than 2.5 micrometres in size that are harmful to health.

Prof Gerry McGovern OBE, Land Rover Chief Creative Officer, said: "The Range Rover Sport is a unique statement of performance with an assertive and powerful design. Its refined appearance speaks to the modernity of the Range Rover family, while a series of unique aesthetic touches mark out its sporting nature."
