VW Polo BlueMotion: 61.9 Mpg on a Single Battery
Autospectator reports that Volkswagen has raised the fuel mileage on its already stingy Polo BlueMotion. Powered by a 1.4-liter TDI [diesel] engine, Volksie's miserly machine deploys every mileage stretcher known to mankind, from special transmission ratios to low-rolling resistance tires. Baby Blue was sipping 3.9 liters of fuel per 100 kilometers. VW's boffins "optimized the engine configuration" to squeeze an extra tenth of a liter efficiency from the mini (small "m") mill, dropping consumption to 3.8 liters per 100 klicks. That's almost 62 mpg folks AND it exceeds all Euro-emission requirements for diesels. VeeDub pulled-off this mpg miracle without relying on hundreds of pounds of batteries and electric motors — if you know what I mean.
