Autocar is reporting that an "experimental engineering" concept will make an appearance in Paris, one that will get 141 miles per gallon vehicle. Why 141 mpg? Because that's the level set by the French government for car companies to reach by 2020. 141 mpg is the equivalent of 1.67 liters per 100 kilometers, if you're keeping track in European units. What technology Renault will use to get to 141 mpg was not disclosed.
Of course, a 141-mpg Renault was promised for the Geneva Motor Show this spring, but that didn't happen. Perhaps the fact that a totally new platform is being used, along with the "dramatic weight reduction and a dramatic aerodynamic improvement" that was needed (according to Renault's design boss Laurens van den Acker), held things up.
