Both Peugeot and Citroën have concept cars on display at the 2014 Paris Motor Show that blend aerodynamics, low curb weights and cutting edge powertrain technologies to return 1L/100km on the European cycle. And now Renault has just unveiled its fuel-saver to the world's press, showing off the Eolab, a concept hatch that promises to use only one liter of fuel for every 100 kilometers traveled.
For the math averse, that works out to about 282 miles per gallon, or a lot. Like the PSA concepts, a low curb weight is key to the Eolab's efficiency. With an overall weight at just about 2,100 pounds, the gas-electric hybrid powertrain, which can run up to 60 km on electric power alone, isn't forced to work too hard.
While PSA based its concepts on actual production models – the Peugeot 208 and Citroën C4 Cactus – the Eolab is more of a pure concept. According to Renault, it employs "100 new, realistic technological developments" that could make their way onto French roads.
