With ice and snow hitting the capital, Land Rover has loaned the ambulance service two Discovery 4 4x4s to cope with the icy conditions.
The loan will allow workers reach emergencies and will even be used to get employees into work in what is one of the busiest times of the year for the service.
Dr Ralf Speth, CEO of Jaguar Land Rover, handed the vehicles over to the service, saying: "When winter road conditions become treacherous, there is one manufacturer that the emergency services turn to – Land Rover.
"Land Rover vehicles offer the best in all terrain capability, making them the ideal vehicles for these winter conditions."
Land Rover, which recently agreed a deal to use Continental winter tyres on its SUVs this winter, regularly supplies the police and ambulance services across the UK in poor weather.
Fitted with Land Rover’s Terrain Response system, the vehicles are built for off-road terrain and wet and icy conditions.
In total, Land Rover supplies up to a quarter of the emergency services, police and ambulance teams across the UK and can often be seen being used by services such as mountain rescue.
The two Discovery 4 models will be loaned to the London ambulance service throughout the winter months.
Capable of seating seven, the Discovery starts from £35,995 usually and includes a host of equipment such as climate control and four-corner air suspension.
The engine range starts with a 3.0-litre diesel engine with six-speed adaptive automatic transmission. However, three other trim levels are available as well as a 3.0-litre V6 petrol engine on range-topping HSE models.
