Traffic Booster honks at drivers as soon as the light turns green

The Traffic Booster is a simple little device: a few resistors, some switches, a box with a cheap car horn in it.

Jaguar C-X75 concept

We waited with baited breath to see what the Jaguar design team had in store at the Paris motor show this year, and we weren't disappointed with the resulting showcar. Created by a team led by Matthew Beaven, Principal Designer at Jaguar Advanced Design, the C-X75 is both a celebration of Jaguar's 75 year history and a design showcase for the company's hybrid turbine technology. Read more about our opinion of the design in our 2010 Paris Motor Show Highlights and see the extensive compilation of images – including sketches and studio shots – in the photo gallery below.

Citroen to launch range of Green, Eco cars

Citroen C-Cactus Concept will form the basis of a new range of Citroen Eco-Cars The first of the new range will be based on the existing C4, but feature bodywork based on the C-Cactus Concept (but a wee bit prettier, we hope) and featuring a range of green and economical propulsion systems. Under consideration are an electric version (EV),  a  form of hybrid technology or simply lopping a cylinder off and aiming to bring the Co2 down to under 100g/km. So that will give Citroen three distinct ranges.
