Mercedes GLA SUV UK launch down a salt mine in Cheshire

The new Mercedes GLA down a salt mine in Cheshire Trying to find an unusual venue for new car launches is something that taxes the brains of car PR teams, and Mercedes came up with somewhere a little left field for the launch of the new GLA Compact SUV – the UK’s biggest salt mine at Winsford in Cheshire. The Winsford Rock Salt Mines – 130 miles of salt mining tunnels running under Cheshire – are the result of salt mining since the 19th century and now comprise of 130 miles of tunnels some 189 metres below ground, a void beneath the earth of 23 million cubic metres. Still a working salt mine, Winsford is also home to a massive storage facility for, among others, the National Archive, where constant temperatures of 14C make for an ideal storage environment.

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.

Nissan to issue recall for faulty part in tire-pressure monitoring system

Nissan Motor Co. plans to recall as many as 143,000 cars to replace a tire-pressure monitoring system nut that may corrode and crack in areas with heavy concentrations of road salt, the government said today. The cracking of the nut in the monitoring system could cause it to fall out of the sensor-transmitter that it secures, the National Highway Traffic Safety Administration said in a report on its Web site.
