Subaru is introducing the R1, an all-new mini car, into the Japanese market. Subaru showed versions of the R1 earlier this year at the Tokyo Motor Show. This R1 is an ICE (internal combustion engine) production version of the R1e battery-electric vehicle concept car that appeared last year (minus the plug-in electric drive system).
The production All Wheel Drive R1 uses a 0.66-liter, 4-cylinder engine featuring an active valve control system and an intelligent continuously variable transmission. Fuel consumption is low: 4.17 liters/100 km, or 56.4 mpg. This exceeds the Japanese 2010 target for fuel consumption for this weight class: 21.1 km/liter, or 4.72 liters/100 km.
The R1 meets Japan’s Ultra Low Emission Vehicle (J-ULEV) standards, which specify HC and NOx emissions of 0.02 g/km—an additional 50% below the HC and NOx levels of the 2005 exhaust emission regulations.
