WHAT IS A PLUG-IN HYBRID OR PHEV CAR?
Plug-in Hybrid Electric Vehicles (PHEV) use a conventional petrol engine and an electric motor powered by a battery that can be recharged through the hybrid system or by connecting to an electricity supply – either at home or at one of thousands of charging stations available across the UK network. The large battery gives the NX 450h+ a range up to 40 miles* in pure EV mode.
With a Lexus Plug-in Hybrid there are two power sources: a combustion petrol engine and a rechargeable electric battery. When charged it can perform as a pure electric car by selecting EV mode but when the battery gets depleted it combines petrol with renowned Lexus Self-Charging Hybrid technology for best efficiency. The pack that powers a PHEV car’s battery is larger than that in a standard hybrid, giving it the advantage that it can run for longer on pure electric power alone.
WHAT ARE THE BENEFITS OF A PHEV?
It can offer a ‘best of both worlds’ solution to the car owner. Utilising an electric motor for a large percentage of journey reduces petrol costs and results in zero tailpipe CO2 emissions at lower speeds. The petrol engine can also act as a back-up in instances when the battery runs low, removing concerns about range and enabling the driver to reach a charging point when required.
HOW DO YOU CHARGE A PLUG-IN HYBRID?
PHEV cars charge their EV battery by attaching a cable to the vehicle and a power source. The EV battery in the NX 450h+ can be recharged either by connecting the car to a wallbox or through the self-charging functionality built into every Lexus hybrid. By charging your car at home, or by using the extensive network of stations across the UK, you can drive without using petrol until the battery is depleted, resulting in zero tailpipe emissions and, when driving in electric mode, significant cost savings in fuel. Crucially, the system maintains high efficiency even when the battery is depleted. You can recharge by plugging-in the car or relying on the self-charging hybrid system to continue your journey.
At a basic level the all-new Lexus NX plugs into your normal socket at home to charge it up. However, a Lexus wallbox is recommended to provide optimum charging at home.
WHAT HAPPENS WHEN THE BATTERY RUNS OUT OF CHARGE?
In this case, the vehicle becomes an efficient self-charging hybrid with the petrol engine powering the car and recharging the battery. With the new Lexus NX an element of self-charging will also take place meaning the battery will slowly be refilled when the conventional engine is in use.
The all-new Lexus NX Plug-in Hybrid draws on over 15 years of experience in pioneering electrification. Power is supplied by 4th generation Lexus Self-Charging Hybrid technology using a four-cylinder 2.5-litre petrol engine specially engineered for use in hybrid systems and a rechargeable 18.1kWh lithium-ion battery – the highest capacity in its class. An additional rear electric motor enables all-wheel drive.
The plug-in system produces 302bhp with an expected 0-62mph acceleration in little more than six seconds. There are estimated CO2 emissions of less than 40g/km and fuel economy better than 94mpg. Lexus electrified efficiency know-how delivers a best-in-class EV range of up to 40 miles* – unlocking lower Benefit in Kind rates – and enables all-electric, zero-emission driving at speeds up to 84mph.
*Estimated Electric range shown is for NX 450+. Electric range figures are provided for comparability purposes; only compare electric range figures with other cars tested to the same technical procedures. These figures may not reflect real life driving results. Electric range can vary significantly depending on a number of factors, including the accessories fitted (post-registration), driving style, conditions, speed and vehicle load.
