McLaren launches P1 'Designing by Air' online experience

McLaren has developed a new online experience, 'Designed by Air' to tell the story of the car's design and development. Designed by Air is the first of a two-part series and gives users the chance to hear in detail how the car was created, as the car appears from raw metallic and carbon elements and is crafted by airflow. The P1 is eventually formed inside a wind tunnel, designed to emphasize the car's aerodynamic qualities.

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.
