Here’s another look at the Volkswagen XL1, the world’s most efficient car. This two-seat diesel-electric hybrid car emits 24 g/km of carbon dioxide and can achieve fuel efficiency of 313 miles per gallon. It was designed from scratch and is lightweight as some steel components, including the chassis, have been replaced by carbon fiber so that the car weighs in at just 795kg.
The edgy design is intended to reduce drag and it features ‘scissor doors’ which were famously featured in the DeLorean DMC-12, used in the Back to the Future films. To achieve the target fuel consumption figure the XL1 was aerodynamically optimized, adopting a classic ‘tear drop’ shape and using innovations such as removing traditional wing mirrors and replacing them with small cameras called e-Mirrors, which transmit exterior images to interior displays.
