Fuel efficiency is becoming a giant focus in Australia, even for luxury car brands. We have yet to see a stop-start system in a Rolls-Royce, or a petrol-electric hybrid Bentley, but both are probably on the way and Ferrari and Porsche are already committed to hybrids in their lineups.At Audi, the efficiency message is spreading fast with all sorts of changes. Its current green flagship is an A4 called the 2.0 TDIe, although it is also mightily proud of the E-Tron plug-in electric concept cars based on its R8 supercar.The A4 fuel miser is a super-efficient turbodiesel with rated fuel economy of just 4.8 litres/100km, and the sort of car which will happily clock 1000 kilometres and more on an interstate highway run. Audi proved its potential with a fuel economy run last year through the outback which reflected its claims on the car.But this test is not about the diesel hero. Instead, we have a car that is much more like the Audi an ordinary person would buy. It runs on petrol power and, despite a couple of economy tweaks, is basically an everyday prestige car.DrivetrainThe Audi in question is official the A4 2.0 TFSI quattro manual, which picks up a stop-start engine system and a gearshift advisory which points you to the most-efficient gear for any driving situation.We will put a diesel TDIe through the Carsguide test soon, but in the meantime the basics of the A4 are much as before with a four-door body, quattro drive in this model, and the petrol turbo engine with a six-speed manual gearbox.
