Auto Express has learned that Toyota is considering naming an entire range after its hi-tech hybrid car - in the same way as it created the Lexus badge for its most expensive machines.

Sources say the company is planning to launch three new dual-power models, starting in 2009. Currently, Toyota engineers call these cars the Prius A, B and C. The A will be a Yaris-sized supermini and the B is planned to be a compact hatchback similar to the current Auris. Meanwhile, the C will be a family model in the same class as the Avensis.

Although Toyota cars will continue to have their trademark conservative styling, launching a new Prius range would allow top brass at the firm to give their petrol-electric vehicles a more adventurous look. The new family"s styling is likely to be heavily influenced by the Hybrid X concept car, which was unveiled for the first time at the Geneva Motor Show in March.

A company insider confirmed: "The exterior design won"t be as controversial as that of the first-generation Prius. However, the intention is for these cars to stand out from the crowd. We need to strike a balance between a shape that"s attractive and has room under the floor for the hybrid system"s batteries, plus space for five people and their luggage."

Engineers have apparently ruled out making a hybrid people carrier for now because they have been unable to accommodate the batteries in a design that buyers would expect to feature a flat floor. This could change with the use of new compact lithium-ion battery technology.
