If XL1 needs 8.3 hp at 100 km/h you can calculate the fuel consumption with few rough assumptations at that speed and it will be 1.8-2.2 liters.

Hey Vekke,

Thanks for sharing that article on the XL1 with us. Here is a quote from the article you posted which sheds some more light on the testing cycle and at what speed as well as its fuel consumption.

"The lightweight XL1 (795 kg, 1,753 lbs) delivers NEDC fuel consumption of 261 mpg (0.9 l/100 km) with CO2 emissions of 21 g/km and an all-electric range of 31 miles (50 km) as well as a total range of 310 miles (499 km). The XL1 has a top speed (electronically controlled) of 160 km/h (99 mph); cruising at a constant 100 km/h the XL1 uses only 8.3 hp (6.2 kW). In all-electric mode, the XL1 requires less than 0.1 kWh to cover more than 0.6 miles (one kilometer), based on the NEDC.

0.1 kWh per km equates to 0.161 kWh/mile, or 16 kWh/100 miles. Even accounting for differences resulting from variations in drive cycles, XL1 appears to deliver significantly better electric fuel consumption than the EPA-rated electric or plug-in vehicles on the US market."

Thanks again Vekke on sharing I think this really helps us see what is possible with modern technology and a hybrid design approach to fuel consumption.

What is buzzing in my mind though is can this be bested and for less dinero?
