Nissan’s new lightweight philosophy revealed

The leaked official drawings of the new Nissan Micra might have revealed the conventional styling of the company’s new supermini, but they gave little clue to the dramatically lightweight new platform that underpins it. The new Micra will be significantly lighter and more fuel efficient than the outgoing car due to a ruthless pursuit of weight reduction on the new V-platform (V = versatile), which on average has slashed 50kg from the new car's weight, and up to 70kg on some models. Project leader Noritaka Tsuru described the new package as a 'breakthrough car' that required a complete 'change in mentality' in how Nissan makes cars.

German courts rule on status of rare Mercedes-Benz 500K roadster

The saga of a rare 1935 Mercedes-Benz 500K roadster has taken yet another intriguing turn. German courts have ruled that the vehicle is the rightful property of German industrialist Hans Prym's grandchildren because it was illegally seized from Prym in 1945. Frans van Haren can't be too happy with the ruling.

MIT researchers rethink electric-car batteries

Researchers at the Massachusetts Institute of Technology say a new battery design for electric vehicles could be a lightweight and inexpensive alternative. The goal for the team's three-year project, launched in September 2010, is to have a functioning prototype ready to be engineered as a replacement for existing electric-car batteries. At this point in the project, the prototype uses a “semi-solid flow” to separate the two functions of a battery--storing energy and discharging it when needed--into separate physical structures.
