Bentley's Birkin Blower goes digital

By CARSIFU | 17 April 2020

CREWE: Bentley’s Blower Continuation Series project has this week reached an important milestone, with the completion of the digital CAD (Computer Aided Design) model that will serve as the master design and engineering reference for the new cars.

Announced last year, the Blower Continuation Series is a run of twelve new Bentley Blowers, each of which will be an exact mechanical copy of the 1929 Team Blower built and raced by Sir Tim Birkin, and now likely the most valuable Bentley in the world.

The Continuation cars are being produced by a dedicated team in Bentley Mulliner’s Classic division, who cut their teeth on the recently restored 1939 Bentley Corniche and who are now working with a team of vintage specialists to re-engineer and build the suite of parts needed to bring the new series of cars to life.

All twelve of the new cars are already sold to keen collectors around the world, and the first stages of build for the Bentley’s own engineering prototype – Car Zero – will begin in earnest soon.

Bentley’s Team Blower has been carefully dismantled and then re-created in the digital world through a combination of precision laser-scanning and intricate hand measurement.

The finished CAD model is comprised of 630 components across 70 assemblies, and is more than 2GB in size.

From start to finish it’s taken 1200 man-hours for two dedicated CAD engineers to complete the model from the scan data and measurements, and the result is that an accurate and complete digital model for a 1920s Bentley now exists for the very first time.

The engineers have been able to complete the model while working remotely during the COVID-19 crisis.
