Audi A3 E-tron concept (2011) first official pictures

This is the Audi A3 E-tron concept, just unveiled alongside the new Q3 SUV at the 2011 Shanghai motor show. It’s Audi’s second A3 concept car in the space of two months – the first was a 402bhp super saloon, but this is a little more eco-conscious, with a plug-in hybrid powertrain – but both preview how the next A3 will look. Does this new Audi A3 E-tron concept still use the first concept's turbocharged 2.5-litre five-pot engine?

One Lap of the Web: Janky Jettaminos, scary supercars and a two-wheeled tour of the Packard plant

-- Our friend Corbin is back! And he's got an even more terrifying car this time: the Jettamino, a Volkswagen Jetta diesel with the structural stability of a pool noodle and the hipster styling of an LCD Soundsystem reunion tour on wheels. (Fabric wheelarches have never been done before, for good reason.) Somehow, Corbin suckered his friend David into chopping off the roof.

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.
