Hey, I'm a fan of big V8s, and sure, they can get impressive highway mpg for the power level, but anecdotal hypermileage stories aside, in fact most people reporting on fuelly.com average about 20mpg in Corvettes.
It's not a question of getting high mpg when you want to or not either. If you're driving in town, you're going to get crap mileage. On the highway, you're going to get amazing-for-the-horsepower mileage.

Meanwhile in the real world, C6 and C7 Corvettes average about 20mpg and 7.0 liter C6Z06 median is 17mpg.
Chevrolet Corvette MPG - Actual MPG from 897 Chevrolet Corvette owners
When my FD had a 6.0 LS2 I got 29mpg for *one* tankful all highway at lowish speeds, with 0.5:1 6th gear and 3.55 diff. Usual highway-only at 75-80mph I'd get ~24-25mpg. But *any* off-highway usage and mpg plummeted. For my 90% highway commute I rarely did better than 22mpg, usually 20. When I went 6.8 LS3 and got T56 Magnum with shorter 6th gear, it went down further...
Meanwhile in the S2000 I regularly got 27mpg for same usage, and with the BRZ I get 30.
I love big V8s, but they are inherently less efficient due to much greater parasitic frictional losses and also rejected heat losses.

Odd, most if not all s2000 -> Corvette owners on these boards also reported vettes getting remarkable gas mileage. Even around town I averaged right around where the s2k got. The FRS though was noticeably better than both. And everyone on vette forums also report good gas mileage, and mags have as well. <shrug>
I definitely got MUCH better mileage for in-town and combined usage with my AP1 than in the LS2 FD. Highway mpg was closer but where the FD got 25ish, the S2000 got 29ish.

The EPA didn't kill the V10... Pretty sure there are 12-cylinder cars out there that get worse mileage than the Viper did. In any case the EPA head works for the fossil fuel industry now so 27 liter W16s will soon be mandated...

I find it kind of funny that you guys across the pond are talking about killing v10 engines, when here at Europe we are talking about EU is killing sport cars and hot hatches as we know them.
From 2020 car manufacturers need to aim average 95g/km co2 figures for cars they manufacture or sell in Europe. This is about 4,1l 100/km and 57 mpg for petrol powered cars.
If you go over you need to pay 95€ for every g/km you go over for every car.
Example: if Porsche would only make 911 carreras (205g/km) they would have to pay 10 grand fine for every car they make, but if half of cars they manufacture are Taycans with 0g/km then they would need to pay only 700€ / car.
For sport car manufacturers fuel ecenomy is really big problem here at Europe. Soon most of them are probably plug in hybrids or full electric.
