Computer simulations point to a top speed of 150mph, a 0-60mph time of 6.2sec and average fuel consumption of 40mpg. As a hybrid, it can move off on the electric motor in stop-start traffic with a seamless transition to petrol power when the road clears. The Connaught contains a wealth of other technical innovations, some of which are the subjects of patent applications.

Right now, the Type-D project exists as a running chassis with a Ford Zetec engine, a full-size model, a collection of aluminium castings and several gigabytes of engineering documents in some computers in Daventry. But if all goes according to plan, which includes gaining the guarantee of another ΂£4m or so of funding, the completed Connaught will be revealed in a year's time with sales starting in May 2006. As a hybrid, the Type-D has already attracted a healthy development grant from the Energy Savings Trust.

The price will be ΂£35,000 for the standard version, more for the convertible whose glass roof slides into the boot. The full-size model, made and refined by Coventry University, was shown at September's Goodwood Revival meeting, and already there are orders in the book.

Its manufacture will not be capital-intensive for its creators because its assembly, and some parts manufacture, will be subcontracted to Derby-based EPM Technology. Some other components, including aluminium castings for the engine and double-wishbone suspension, will come from low-cost overseas sources to Connaught's design.

Plans are to make 50 cars in the first year, then move on to an ambitious 2000-a-year target. The intention is to fully homologate the Type-D and to subject it to the EuroNCAP crash test, which Connaught optimistically hopes to pass with a five-star rating.

The Type-D is a bold project that makes some bold claims; we'll follow its progress with interest.
