Hiall, Just got back from Alfa Romeo Owners Club Australia's annual national gathering "Alfesta". We took our new 159 3.2lt on it maiden long drive. About 1500 kms there and back. I was disappointed by the fuel economy. The best the computer read was 9.5lt per 100kms (about 29.73MPG). That's travelling at 100kph on the level.
AlfaRomeo 159 2008 2.2 JTS fuel consumption is 9.2 litres per 100km in combined city/highway mode (10.9 km/l), fuel consumption in city - 12.8 l/100km, highway fuel CdEcVTg. 14 379 9 274 277 186 97 464 472
