Fast, fun, 62 mpg - NOT YOURS in  the U.S.
 :Edmunds.com  ...the  Polo Blue Motion promises Toyota Prius -beating fuel  economy at the low price of $19,990.
Its Lupo 3L, the advanced  78-mpg city car masterminded by former chairman Ferdinand Piëch,  proved just what is capable if a carmaker is prepared to forgo profits.  Unfortunately, the disappointing sales figures — only 28,000 units were sold in  six years — meant the mileage champ was ultimately dropped from the German  carmaker's lineup. That's a 8.3-mpg improvement  over its standard sibling, made even more impressive by the car's 717-mile  range.

 What about  the the Billion dollar prize at 100mpg posted by The L.A. Times?  Time to pony up  Dan... The VW  Lupo 3l actually does close to 100 mpg not just the 78 mpg. The mathematics are  really pretty simple. In the UK a gallon = 4.5 litres. The car goes 100km on 3  litres of diesel so it goes 150km on 4.5 litres or 1 gallon. 150km converts to  93 miles so the Lupo 3L does 93mpg. Even better, it can be simply converted to  run on 100% rapeseed oil which is completely renewable and the only co2 emitted  is that which was absorbed by the rapeseed plants when they were growing.  Rapeseed oil can be bought for 50p a litre in the UK compared to diesel which is  now approaching £1 per litre! 
 So, to conclude, we  should all be buying up Lupo 3l cars and running them on rapeseed oil.   How does £9 to  travel 372 miles sound?  
 I as well fail to see how  this is breathtaking. My parents used to drive a Toyota that got 50pmg from the  70's. Good Ol' Fashioned engineering maybe, but it is certainly  not fascinating. If automotive technology had kept it's innovation at the same  pace as CPU technology, we would be driving some amazing  vehicles.
 But US manufacturers are still using the same basic  combustion engine design that was invented in the late 1800's. This is probably  one of the few industries that have been manufacturing 100+ year old  technology.
