A new state-of-the-art engineering test facility, built at the headquarters of Bentley Motors in Crewe, U.K., is nearing completion following an official 'topping out' ceremony.

In place of the traditional final beam marking the occasion, a native British Oak tree was planted by Members of the Bentley Board for Manufacturing and Engineering, laying down roots for the future.

The facility will complete full internal construction and open in 2021, covering more than 4,600sqm over two storeys. Included is 773sqm of office space and 1,550sqm designed for the installation of a single climate-controlled chassis dynamometer, operating across a range of temperatures from -10 degrees to 40 degrees Celsius.

There will also be a dedicated laboratory to run Real Driving Emissions using the latest state-of-the-art portable emissions measurement systems. Bentley's Technical Conformity department will be based in the test centre, with over 100 people working in the building.

The centre will allow Bentley to meet increased consumer demand for its current range of ultra-luxury vehicles, including the performance-orientated Flying Spur, the Continental GT and the new Bentayga.
