( CNN ) -- Speed and beauty have long been the driving factors in car design , but this year 's most exclusive automobiles include a few practical considerations such as alternative fuel sources and smart ideas to improve safety and cut urban congestion . Still , the first thing about these cars that catches the eye ai n't the miles per gallon ( or perhaps mile per watt ) . Yes some of these French , Italian and German automobiles are more environmentally friendly -- but more importantly they look good doing it . Many of the car designs at the 2010 Paris auto show focused on electric-powered cars . Energy is a central theme of the Automotive X Prize -- a self-described `` $ 10 million competition to inspire a new generation of viable , superefficient vehicles that people want to buy . '' The contest pushed designers to come up with a conventionally powered vehicle that would top 100 MPGe ( miles per gallon energy equivalent ) . Some of the names that grabbed attention in Paris , and at the X Prize competition and elsewhere will captivate many drivers ' imaginations : Lamborghini 's Sesto Elemento , the Ferrari SA APERTA , Bugatti 's Super Sport and the literally electric Jaguar C-X75 . The folks at Mini are offering a surprise : A scooter ! Renault 's electric concept car -- the DeZir -- looks like it has wings to fly . While many of these cars could empty more than a few pocketbooks , they also could save their owners a few bucks on fuel .
Hot cars of '10 include Ferrari 's SA APERTA , Bugatti 's Super Sport , Jaguar 's electric C-X75 . Some of them were featured at the 2010 Paris auto show . Others competed for the $ 10 million Automotive X Prize .
