In September 2017, Land Rover announced that both the Range Rover and Range Rover Sport would be available with a Plug-In Hybrid electric (PHEV) Engine option. A first for any Land Rover vehicle.
How does the PHEV technology work?
The P400e Plug-In Hybrid (PHEV) engine uses the combination of an advanced 2.0 litre 300hp Ingenium petrol engine and a high capacity 85kW electric motor. In ‘Parallel Hybrid Mode’ the two engines work in unison to not only deliver a combined output of 404hp, but also a consumption of up to 101mpg and CO2 emissions from 64g/km*. The electric motor can also be used by itself in Electric Vehicle (EV) mode. A large 13kWh battery means an all-electric range of up to 31 zero-emission miles* is possible from a full charge.
How Parallel Hybrid Mode works:
Both the 85kW electric motor and the Si4 Ingenium petrol engine are used simultaneously through a hybrid integrated transmission system, which merges the electric and petrol engine power together.
To ensure that the P400e engine retains sufficient charge throughout a journey, intelligent battery management charges the battery when the vehicle is in motion through regenerative braking and ensures there is no dip in performance with 404hp delivered at all times. The driver behind the wheel can also optimise fuel economy using two charge management functions:
SAVE Function - prevents the battery charge dropping below the level which has been selected.
Predictive Energy Optimisation (PEO) - by entering a destination in the Navigation system the driver enables the feature, which utilises altitude data for the route selected to intelligently switch between the electric motor and petrol engine to maximise fuel economy.
Does a PHEV engine affect performance and capability?
As with all electric or hybrid vehicles, the electric motor within the P400e engine can produce its maximum torque from standstill. The result of this is that the combination of electric motor and a highly efficient petrol engine, delivers torque similar to a large capacity diesel or petrol engine, resulting in 0-60mph in 6.4 seconds.**
The off-road capabilities you expect from a Land Rover also remain uncompromised. For example, Range Rover’s wading depth – yes, you can still wade in a Plug-In Hybrid Electric Vehicle - is exactly the same with a PHEV engine option (900mm) as it is with a conventional internal combustion engine. The additional torque at low speed provided by the electric motor is also a benefit when driving off-road.
The 13kWh battery within the P400e can be charged fully in as little as 2.75 hours using either a wall box, or a 32 amp industrial type socket, such as those found at public charging stations. In terms of charging at home, this can be done in 7.5 hours using a standard power supply and using the charging cable supplied with both Range Rover and Range Rover Sport as standard. This equates into an ideal overnight charge ready for the following morning’s commute.
This cutting-edge hybrid engine technology is a first step towards Land Rover’s pledge to offer a fully-electric or PHEV powertrain option for all models from 2020. Using renewable energy in our vehicles hugely reduces Land Rover’s reliance on fossil fuels, enabling us to cut CO2 emissions. Combined with energy-efficiency measures, this helps to reduce absolute CO2 emissions, so even as our vehicle production continues to rise, it allows Land Rover to work towards a cleaner future.
