2013 Audi A8 3.0T matches 4.2 V8 fuel economy numbers
When Audi announced the 2013 A8 with the 3.0T V6, it didn't mention fuel economy numbers but did tout the 333-horsepower engine's "great efficiency." According to the United States Environmental Protection Agency, the V6 efficiency exactly matches that of the more powerful 372-horsepower, 4.2-liter V8 – the 3.0T was rated the same 18 city, 28 highway as the naturally aspirated 4.2.
It's figured that the stop/start system fitted to the V6 will provide a slight bump, which, since the EPA doesn't factory such tech into its testing, doesn't register in the official numbers. It's difficult to make fuel economy comparisons with the same engines in other countries since they have different power ratings; in Germany, for instance, the V6 is rated at 286 hp, the 4.2 isn't offered and the 4.0 TSFI V8 makes 414 hp – but in that case, the V6 does get better gas mileage, if you're wondering.
Speaking of wondering, that's what many including our own commenters are doing about the space between the 333-hp V6 and 520-hp V8 in the S8. The report in Car and Driver posits a detuned version of the S8's motor. No matter what, the V6 A8 will be less expensive than all of them, which was the real point all along.

The 3.0T should be a cheaper engine for them to add in the A8, they can offer the v6 A8 at a lower price. Smaller sized engines get taxed less in Europe. Not sure why the 3.0T gets the same fuel economy as the V8 both city and highway, that is kind of disappointing. Maybe it has to do with the transmission/gearing. How does the 520hp V8 in the S8 get the same/better fuel economy then the 333hp V6?

The only reason for an entry level V6 is based on price. Like BMW and the 740i or an upcoming MBZ S350 possible LS350. But certainly after lowering the price as priority, fuel economy is the 2nd greatest attribute. Unfortunately its not the case for Audi's flagship

Similarly Audi's own 3.0T (supercharged) puts out 272hp 295lbft or 333hp 325lbft in the Q7

The 3.0T mpg numbers are not that disappointing. It's just that the 4.2 V8 gets VERY good numbers, making the V6 numbers appear bad. The V8 is a double-edge sword.
