My thoughts on all things motoring, press releases, reviews & techie stuff, from around the world.
Please note that the pictures of vehicles within this blog are used as examples of the specific press releases, on occasions, due to the lack of available official pictures, examples are re-produced.
ANY AND ALL PROFANITIES WILL BE REMOVED AND THE PERSON/S RESPONSIBLE WILL BE BANNED, NO EXCEPTIONS.
I will try my best to provide detailed info on various cars and what is like to live with them, I have already produced a few for Jaguar-car-forums, I will do my best to be unbiased, but it will be hard for some cars. I will re-produce press releases and copy from other motoring news.

Audi debuts on its R8 Supercar a new style of matte lettering and graphics on the sideblades.
New patented process enabling matte lettering and graphics to be embedded in painted surfaces makes its debut in R8.
Patented process modifies surface sheen to create matte lettering and graphics
Audi Board of Management Member for Production Prof. Dr. Hubert Waltl: “A high degree of individualisation with maximum efficiency and flexibility”
Available for the first time as part of the Audi exclusive programme for R8 Coupe and Spyder models
Owners have always been able to make an impression with the Audi R8, but now they can also make their mark on one thanks to a new Audi-developed process for the partial matting of painted surfaces that enables virtually any lettering or graphics to be precisely ‘blasted’ into the painted surface of the car’s distinctive sideblades.
A special powder roughens the clear lacquer on the surface to a depth of a few thousandths of a millimetre so that individual markings become visible, making each R8 which undergoes the process unique.
As the desired symbols are applied to components after being painted, the process can easily be integrated into normal series production.
“The method of partial matting is an excellent example of the flexibility of our production. Being able to implement individualisation in normal series production is one of the aims of our smart factory,” stated Prof. Dr. Hubert Waltl, Member of the Board of Management for Production at AUDI AG.
Painting a car consists of – in addition to the cathodic dip coating to protect against corrosion – at least three further coats: filler, base coat and the transparent lacquer as the top protective coat. With the newly developed process, a template of the desired pattern is first placed on the component. A blasting system then sprays a special powder onto the surface, which roughens the clear lacquer to a depth of just a few thousandths of a millimetre – less than a tenth of the thickness of a human hair. This creates the effect of a matt and homogeneous pattern.
“With this process, we modify the brilliance of the paintwork and the intensity of its sheen. Light hitting the surface is then reflected diffusely by the individualised surface areas. This makes it appear matt,” explained project manager Dr. Erhard Brandl. Production section head Mirko Endres added: “This form of individualisation is weather resistant, unlike conventional lettering and stickers, and it has a much more high-quality appearance.”
The Audi paint shop can apply almost any pattern that a customer requests providing it does not affect any third-party rights. At present, components with a size up to a metre by a metre can be processed in this way. The Audi R8 super sports car in both Coupe and open-top Spyder forms is the first model for which this technology is offered through the Audi exclusive personalisation programme. This option will also become available for other models in the range in the future.
