BMW EfficientDynamics hybrid supercar: production confirmed

BMW today gave the green light for production of the dramatic Vision EfficientDynamics hybrid supercar shown at the 2009 Frankfurt motor show. Munich admitted today that the tech underpinning the concept car was 'completely or virtually production-ready' and said that the car will be launched very much as shown in Frankfurt. It has started roadgoing tests of the 2+2 EfficientDynamics sports car and its three-cylinder turbodiesel hybrid system.

Hyundai i40 saloon – that’s the Euro version – finally arrives

It's the Hyundai i40 Saloon for Europe As we reported last week – after Hyundai had, rather pointlessly, teased us with an image – the European version of the Hyundai i40 saloon is about to launch at the Barcelona Motor Show. So we have details, although much of what we have is what we already know from the Hyundai i40 Estate. What we do know is that the European  i40 – whatever guise it comes in – seems a fine car and a real threat to the sector domination by the Ford Mondeo and VW Passat.

Bentley uses 3D printing to prototype new designs [w/Video]

3D printing is changing the way the world makes things by helping people of all disciplines to enhance and refine their ideas cheaply, quickly and effectively.  Bentley is the latest carmaker to utilize the technology to fabricate and prototype different parts to see how they'll look and work on the finished design. Using 3D printers, designers can produce parts from the exterior and interior such as the grille, tires, headlamps and door handles as well as combine different types of contrasting materials, ranging from hard plastics to rubbers of different tensile strengths.  The technology allows the user to create a solid 3D object straight from a digital model by printing layers of material on top of each other. This process rapidly decreases the delivery time, as parts can be printed overnight, and allows designers to be more creative in their ideas because of the reduced cost. Bentley isn't the first carmaker to use 3D printing technology. Audi announced last year it was beginning to prototype vehicle parts using 3D printers.
