Question: are audis good on gas?
Answer: In its most basic configuration, the Audi A4 returns 30 mpg in a combined cycle, 27 mpg in the city, and 34 mpg on the highway. Achieving those figures requires front-wheel drive, Audi's time-tested Quattro all-wheel-drive system inevitably lowers efficiency. ... While it's efficient, it's certainly no slouch.
