#RS7

Audi will release a sedan version of its uber-A4 sometime next year, Autocar is reporting.

Audi has already confirmed that the RS4 would be released as a wagon because “that is what people expect from the RS4,” head of Audi’s Quattro Heinz Hollerweger told Car and Driver this month.

That’s on top of speculation that the RS4 could come to the States and China as a Sportback, similar to the RS7 already on sale. And, of course, we could always get the RS5 like we did last time.

With a broader product portfolio and extra decades of established premium status in the United States, Mercedes-Benz USA sells a lot more vehicles than Audi USA. Through the first four months of 2015, Mercedes-Benz sales were up 9% to 107,344, excluding Sprinter. Audi, globally favored, was up 12% to 56,925.

But again, the comparisons are difficult to make because the lineups simply don’t, well, line up. We’ve discussed the CLA and A3 before, but even there, Audi is offering different bodystyles under one banner, which Mercedes-Benz does not. The S-Class has a significantly higher base price than the A8. The E-Class is available as a sedan, wagon, coupe, and convertible – the A6 is sedan only. The GL is significantly pricier than the Q7; the Q7 offers more seats than the ML. The C-Class is new; we might as well wait for a new A4 to draw realistic comparisons. The SLK is a hardtop convertible; the TT is either coupe or convertible.

You get the idea. Only in a handful of zones do the two brands offer truly direct rivals. GLA vs. Q3, GLK vs. Q5, and the matter at hand, Mercedes-Benz CLS vs. Audi A7.
