Revolutionary autos: lighter weight and advanced powertrains


Some autos currently on the market display specific aspects of Revolutionary design, and are progressing on the path towards truly Revolutionary autos. While some manufacturers have moved down the y-axis by pursuing advanced propulsion systems, truly Revolutionary vehicles will pursue both aggressive lightweighting goals (moving along the x-axis) and some form of powertrain electrification. For example, both the GM Volt and Nissan Leaf employ highly-efficient electrified propulsion systems and are marvels of powertrain engineering. However, their weight leaves far too much efficiency potential on the table. Tesla's upcoming Model S is predicted to weigh about 35% less than a comparable auto, giving the aluminum-based battery electric sedan more range and greater efficiency. Models like VW's XL1 and the Toyota 1/X exhibit real Revolutionary design. Their use of lightweight composite materials coupled with superefficient hybrid powertrains push them into a whole new realm of automotive efficiency and potential strategic advantage.
