After 40,000 hours of work, Bentley Mulliner has completed the first new Bentley Blower in 90 years, with the delivery of Car Zero – the prototype car for the Blower Continuation Series.

This highly exclusive run of 12 customer cars – all pre-sold - will be crafted from the design drawings and tooling jigs used for the original four Blowers built and raced by Sir Henry ‘Tim’ Birkin in the late 1920s. Specifically, Bentley’s own Team Car (Chassis HB 3403, engine SM 3902, registration UU 5872  - Team Car #2) has provided the master model for the Continuation Series, with every single component laser-scanned as part of a wheels-up, sympathetic restoration.

From this data, 1,846 individual parts have been designed and hand-crafted to create the new Blower. 230 of those parts are actually assemblies – one of which being the engine – taking the total part count to several thousand when fixings and interior trim parts are included. Each of these parts and assemblies have been created by a project team of Bentley Mulliner engineers, craftspeople and technicians working together with a number of British specialists and suppliers.

Blower Car Zero is a dedicated test and development prototype, built in advance of the 12 customer cars, and will be subjected to months of durability and performance testing. Finished in gloss black, with an interior in Oxblood red leather from Bridge of Weir, Car Zero made its debut to officially mark the creation of the new Bentley Motors campus in Crewe. Made possible by the closing of Pyms Lane – Bentley’s address since 1946 – the campus extends Bentley’s headquarters to a new expanded footprint.

Chairman and Chief Executive of Bentley Motors, Adrian Hallmark, had the honour of driving Car Zero down Pyms Lane to mark the occasion, and comments:

“Today was a truly remarkable day, not just as a milestone in the Blower Continuation Series project but also for Bentley Motors. To drive the first new Blower in 90 years was a privilege, and the quality of the car would make Sir Tim Birkin himself proud. 

“It was also significant that I could drive the new Blower down Pyms Lane, now part of our main site as we expand to create the new Bentley campus. Investing in our headquarters is vital both for Bentley’s future and for Crewe, and our new developments and buildings are a physical manifestation of the exciting future before us as we start our journey to become the world leader in sustainable luxury mobility.”

The Blower Continuation Series is the first customer-facing project delivered by the new Bentley Mulliner Classic portfolio, one of three new divisions of Mulliner alongside Coachbuilt (currently developing the equally-exclusive Bacalar) and Collections (responsible for the Continental GT Mulliner).

Blower Car Zero – A Project of Draftsmen and Craftsmen

The first step in creating Car Zero was an extensive analysis of the original design drawings and drafts that were referenced in the creation of the original Blower Team Cars, together with archived period photographs of the cars. Following a piece-by-piece disassembly of the #2 Team Car owned by Bentley (likely the most valuable Bentley in the world) and an exceptionally precise laser scanning of the frame and its components, a complete digital CAD model of the Blower was created.

From there, a team of artisan specialists were recruited to start manufacturing the components that Bentley Mulliner would bring together to form the first Blower.

From the outset, Bentley Mulliner sought to engage the very best specialists across the country to create componentry for the Blower Continuation Series in a manner befitting such a project – using traditional techniques passed down through generations.

The chassis has been created in heavy-gauge steel, hand-formed and hot riveted by the specialists at Israel Newton & Sons Ltd. 

The Vintage Car Radiator Company, based at Bicester Heritage, has crafted exact recreations of some of the Blower’s key components – including the mirror-polished, solid nickel silver radiator shell and the hand-beaten fuel tank formed in steel and copper. 

Leaf springs and shackles have been made to original specifications by Jones Springs Ltd, a specialist in the West Midlands with nearly 75 years of experience.

The Blower’s iconic headlamps have been reborn by Vintage Headlamp Restoration International Ltd in Sheffield. 

Meanwhile, in the bespoke Mulliner Trim Shop in Crewe, a new ash frame created by Lomax Coachbuilders (based in Ludlow) underwent final stages of carpentry with Mulliner’s team of experts, including the application of 25 meters of highly specialised Rexine material used to wrap the body. 

Breathing New Life into an Iconic Engine

Car Zero’s brand new 4½-litre engine, originally designed by W.O Bentley himself, has been created with the expert support of specialists including NDR Ltd in Watford. Featuring many innovations of which a sports car engine of the 1970s would be proud – aluminium pistons, an overhead camshaft, four valves per cylinder and twin spark ignition – the renowned 4½-litre engine has been paired with a newly machined Amherst Villiers roots-type supercharger. The newly created Blower engine is an exact recreation of the engines that powered Tim Birkin’s four Team Blowers that raced in the late 1920s – including the use of magnesium for the crankcase.

The Next Step

With the build of Car Zero now complete, a programme of real-world durability testing will begin. Sessions of gradually increasing duration and speed will check functionality and robustness under ever harder conditions. The test programme is designed to achieve the equivalent of 35,000 kilometres of real-world driving across 8,000 kilometres of track driving
