|The 69 mpg EcoRacer|
At the Tokyo Motor Show, Volkswagen is presenting its EcoRacer—a mid-engine diesel sports car with fuel consumption as low as 3.4 liters/100km (69 mpg US) and a maximum speed of 230 km/h (143 mph).
Powered by a 100-kW (134-hp) turbo diesel, and with a carbon fiber reinforced plastic (CFP) body and weight of just 850 kg (1,874 lbs), the car accelerates from 0 to 100 kph in 6.3 seconds.
The 1.5-liter TDI diesel is still under testing at Volkswagen, and represents the highly-charged downsizing approach represented in the new twin-charged TSI family of engines (earlier post). (In other words, using super-, turbo-, or dual-charging to increase power, and then applying that in a smaller engine to reduce overall fuel consumption.)
Volkswagen also notes that the new TDI has the potential to implement its Combined Combustion System (CCS) process—a homogeneous combustion process optimized for synthetic fuels.
Along with the 100-kW power output, the new TDI develops torque of more than 250 Nm between 1,900 and 3,750 rpm. The compression ratio is 17.2:1. The EcoRacer uses the DSG double-clutch transmission. (Earlier post.)
The EcoRacer TDI conforms to the expected Euro 5 emissions standards.
VW is also using Tokyo as the venue for the world premiere of the new Polo GTI. With 110 kW (150 hp) of power, it is the strongest Polo since the series was introduced thirty years ago.
