An updated version of the Audi A1 1.6 TDI with increased fuel economy and lower CO2 emissions has been introduced into the British market. The Ingolstadt firm’s engineers optimized the 1.6-liter turbo diesel’s fuel system and engine management software, and as a result, reduced CO2 output from 105g/km to 99g/km, and boosted its combined economy figure from 70.6mpg UK to 74.3mpg UK (equal to 3.8 lt/100 km and 61.9mpg US).
