The Bolt concept was almost entirely designed and built in Birmingham.

Birmingham, Britain's second biggest city, has been a manufacturing and technology centre since the industrial revolution and has had a long and fruitful relationship with the automotive industry.

After all, the B in iconic motorcycle brand BSA stands for Birmingham, and Jaguar's Castle Bromwich assembly plant in the Castle Vale district of Birmingham turns out XF, XJ and XK models in a factory that produced Spitfire fighter aircraft during the Second World War.

Birmingham manufacturers also supply components worth more than £4 billion (R50 billion) a year to global automakers such as Land Rover, BMW and Toyota.

It's also the home of rock pioneers Black Sabbath, regarded as the first heavy metal group - but the drawing above shows altogether a different kind of heavy metal, called the Birmingham Bolt.

It's a high-performance sports-car concept, designed and built in Birmingham to promote the city's technical expertise in the automotive field, and it will be shown for the first time at the New Delhi auto expo, starting on Friday, in an effort to attract investors from India's robust auto segment.

The odd thing, though, is that the guys behind it are not your usual bunch of petrolheads; it's been commission by the bean-counters who run the city's strategic investment body, Business Birmingham - and practically all the components have been sourced from the Birmingham area.

Business Birmingham's transport technologies and manufacturing investment manager, Martyn Mangan, explained: “The Bolt is a high performance, premium concept vehicle design that incorporates advanced engineering capability and precision parts sourced almost exclusively in the Birmingham area.

“Our established automotive supply chain means that the majority of the Bolt's body, chassis, interior and underlying componentry could be supplied locally to see this design, or one very much like it, accelerate from the drawing board and on to the street in less than 18 months using our existing research, development and manufacturing base.”

The technical drawing above is the only illustration of the Birmingham Bolt released so far, but we'll bring you more details and real pictures as soon as the covers are off in New Delhi.
