Back at 2006 when I was "rich" (I have couple of small businesses go bust), I had a new Toyota Avensis (about camry sized) 2.2 diesel, 147hp, 229 lb-ft torque, 9sec 0-60, but it still made about 50mpg on highway. I had a guy visiting me from Florida and he though I was BULLSHITTING him when I showed him mpg numbers on car computer
Peugeot just started selling a Jetta sized budget sedan called 301 here that averages with 1.6 diesel 63mpg on highway and 49 in the city. And local car journalist confirmed those numbers after test drive (often factory mpg numbers are not real)
Beat that...
