EPA rating for 918 Spyder: 20/24

I was expecting a tiny bit more, but then again this car is quite a fatty and isn't aerodynamically as good as some competitors.

20 MPG city is pretty amazing for a 608hp 4.6L V8. Gets better MPG than any 911 and is considerably quicker.

So I can expect similar mileage to my BRZ? Great!









Now to come up with the money.

Do you have any numbers for your claim that it isn't aerodynamically as good as some competitors? If anything, it looks lower drag than the P1 to me. Besides, 20/24 is pretty darn good for a 900hp supercar...

Porsche claims 0.36 which is the same as the claimed numbers I found for the 12C, but McLaren has explicitly said the drag on the P1 is lower than the 12C. Jalopnik says 0.34, I dunno where that came from though.

Subjectively, the targa style 918 should probably at least be producing more drag from the cabin area due to the open cavity where the exhaust comes out, and the wing that doesn't fold all the way in like the P1. The convertible design compromises aero a little.

Fixed.

Ah okay, I just calculated the highway revs: 2200rpm @60mph. That's a little high for a 4.5L V8. I don't know how the hybrid system works exactly but I imagine it charges for a while, and then shuts the engine off and cruises on electricity for a while, but I'm guessing the motor-generator doesn't put out that much juice at 2200rpm so it doesn't boost the efficiency a whole lot. A 4.5L V8 with that kind of gearing, non-hybrid, you would expect maybe a little under 20mpg highway.

LOL, I always think it's funny when people are concerned with the fuel mileage on a million dollar car. If you can afford the car, then you can certainly afford the fuel.

I don't think it's ever a concern about money, unless you use the car to commute and you have to drive a long distance. Obviously things like brakes, tires, insurance, etc. will cost way more.

The problem is if the car guzzles fuel too quickly, you end up needing to refuel a lot, which is really annoying. Your typical gas guzzling supercar has only half the fuel range of a normal car. One of the things I love about my MR2 is that I feel like I never need to refuel. The 918 having solid electric range plus solid overall mpg means it can be refueled way less than the typical SUV or large sedan which has similar gas-only range but no electric power.

Yeah, it makes sense, unless they have a larger than average fuel tank. But I mean, how likely are these cars to go touring on long trips or even be driven often? Usually when people buy cars like these, they rarely drive them. It's more of a weekend car. Not that I don't commend them for trying to make it more fuel efficient. It makes sense in endurance races at least, which I hope to see it in.
