12th July, 2013
Briggs Automotive Company (BAC) is about to relocate production of the BAC
Mono to Speke Hall Industrial Estate in South Liverpool, England, of what may be the world's first, road-legal,
single-seater production car.
Currently, the company fulfils orders from a sub-let industrial unit in Holmes Chapel, Cheshire.
With plans to grow the business, the Briggs brothers required facilities that would permit production of 100 units per
annum.
Neill and Ian Briggs founded Briggs Automotive Company (BAC) to manufacture their idea of a car that could be seen in
the pits at a race track or on a country lane.
The Briggs brothers vision for the Mono was to make a road car with the same level of intuitive direct control as a
Formula racing car. Aimed at individuals with an interest in motor sport, the car, while road-legal in the UK, is
primarily aimed at the track-day market.
Launched in 2011, the hi-tech vehicle features a carbon fibre composite construction over a steel chassis. It also
boasts the sculpted, sleek lines. It is powered by a 2.3 litre, 285bhp four-cylinder power plant, with the engine mounted
longitudinally to optimise the centralised balance of the car.
Managing Director at BAC Ltd, Neill Briggs, said: “This expansion and job creation will allow us to meet sales
demand around the world, and build on the fantastic interest Mono has received since it was launched.”
Presently, the low volume BAC Mono in sold in the UK, China and USA.
