Britain's most expensive car park?

The Bentley factory in Crewe has just become the UK's first carbon neutral luxury car plant.

Rows and rows of the designer motors can be seen at the site, where models such as the Mulsanne, the Flying Spur and the Continental are manufactured in their workshop.

A brand new Bentley Mulsanne would cost £238,700, meaning there could be millions of pounds worth of hardware on display in our video.

The classic British car maker is also set to launch the new Flying Spur in 2020, said to be the most advanced car the firm has ever built.

Nearly 200 people handcraft every Flying Spur through 84 different assembly stages, an example of the extraordinary eye for detail Bentley is famed for. However, despite the price of the cars, the focus is on using sustainable energy in a bid to go greener.

As of this month, the Crewe factory uses electricity from 100% renewable sources to power its machinery. Bentley Motors will also offer a hybrid variant of all models by 2023 and an all electric version by 2025.

Adrian Hallmark, CEO of Bentley Motors, said: "While 2019 has marked Bentley's centenary, our focus is now on preparing the business for the next 100 years.

"We want to lead the way in the delivery of sustainable luxury mobility, by providing our customers with products and services that reflect their own values.

"We are very conscious of our responsibility to consider the environmental, social and economic impact of our organisation. This is just the latest stage in this journey."

John Newton, Head of Certification at the Carbon Trust, said: "The initiatives that Bentley has undertaken to achieve certification demonstrate the company's commitment to becoming more sustainable. Bentley is making a long-term strategic commitment to delivering sustainable luxury mobility."

Earlier in 2019, the firm also installed the UK's largest solar car port, which covers over 1300 spaces in the factory car park. More than 10,000 solar panels were installed in the scheme, which offers vehicle shading while generating green electricity at the same time.
