Feels like a real Gas Guzzler...
Traded in my 3rd Corvette Z51 C7 convertible for this 2017 F-type R convertible.
Having a blast with it. Although both cars' gas tank holds the same 18.5 gals, & have similar EPA fuel economy of 15 city, hwy: 25/vette, 23/Ftype, & same 18 combined mpg. But seems like the gas tank empties a lot quicker & I'm refilling at the gas pumps alot more often. So what's most likely culprit? 1. F-type's 550 hp vs Vette's 460 hp. So guess I'm stomping on the gas a lot more often. 2. F-type's AWD vs Vette's rear-wheel drive. So I'm stomping on the gas a lot more often to try to get some tire sliipage. 3. F-type's 500% better & awesome exhaust note. So I'm at higher revs to hear the exhaust burble & brapping with the top down. 4. Faster acceleration with the F-type between lights to hit over 60 mph, just to see the rear wing deploy. 5. Putting more 50% miles on the F-type than the Vette b/c of the reasons above. 6 My wife actually drives the Jag a lot more often, since she won't drive the Vette. So glad top-tier supreme unlead is only $2.59 today here in TX... |
How to Hypermile: Driving Secrets That Max Out Your Petrol Mileage | Lifehacker UK
GRIN As to your individual points: 1. With more power, wouldn't it take LESS throttle to avoid bumping into the car ahead of you? (I'm from NJ if you can't tell) :icon_verzsilly: 2. You WANT slippage? :icon_really: 3. Can't fault you here. I LOVE the sound, too. Luckily, the EPA's testers are deaf. 4. Here's a savings: flip the switch so that your rear wing is ALWAYS deployed. 5. :icon_biggrin: :icon_biggrin: :icon_biggrin: 6. My wife (the 'owner' of our Jag, it's HER CAR she keeps reminding me) never gets as good MPG as I do in all our cars. She accelerates harder, accelerates unnecessarily quickly up to the next traffic light without provocation, and isn't as smooth with the RH pedal. (I love her anyway!) :icon_clapclap: |
I've found my 550PS F-Type is more fuel-efficient than my previous 510PS XKR, and they're both driven the same way (like I stole 'em!). :D
|
My 2016 R has been more fuel efficient than my old 2011 V6 Mustang. I'm getting almost 22 mpg combined.

Wait until the UK folks chime in about the price of petrol...
|
Oh, forgot one more item: Corvette shuts goes from V8 to V4 to shut down to 4 cylinders once on cruise control on the freeway to get 30+ mpg in Eco mode. Wished F-type does that in the coming years...

Forget the UK $2.39 per LITRE here in NZ and thats for the lower octane (91we have 95, 98 and in some lucky places 100, don’t ask the price :( ) |

The Corvette LS engine is incredibly efficient - I've had four of them. I once took a 250 mile trip, nearly all interstate. and averaged 32 MPG in my 2012 Z06. I don't expect my F-type R to do nearly that well.
BTW, no shut down of 4 cylinders at light load in that car. |
Yep. I didn't expect the 550 hp F-type to beat the 460 Z51 Vette (which my best freeway run ave 31 mpg), but Wow, your 650 hp Z06 gets 32 mpg...?
I've heard rumor that once at speed & on cruise control on the freeway, the Vette shuts down One bank of 4 cylinders, to leave the other 4 to only need to produce 13 hp to keep it going. Maybe the Z06 better aerodynamics gets better gas mileage... |
I have managed a 32.5 mpg (US) on a 140 miles drive on country roads (not a fun drive, but lots of trafic and lots of speed cameras made it a sensible one….) with my MY15 R.
So you can get pretty decent mpg with the V8 if you want to - but I would say it's not something you do "on purpose". It's a lot more fun to see way lower mpg figures :icon_wink: |
I've never gotten close to 30 mpg. My best is more like 22 mpg.
|
Worth mentioning again... everyone who actually measures their fuel economy finds that the F-type trip computer is 1-2mpg optimistic.

It's a lot more fun to see way lower mpg figures :icon_wink: Urban commuting under 20mpg, approximately 18mpg. Actually usually get mpg between these two extremes when driving in sporting manner (in region of 22mpg) Like most cars mpg varies considerably depending on how it's driven. TVS supercharger is much more efficient than earlier rootes types and has very low parasitic losses when off boost, direct fuel injection also benefits efficiency and hence can improve fuel consumption whilst being emissions friendly |

All I know is, there is little that can match Jag's SPG (smiles per gallon). |
When you drive a boring car the most interesting thing you can talk about is mpg. Obviously we don't have that problem. ;)

Are we really talking about getting good or better MPG in our "R"??? The lower my MPG the happier I am...... Let's get our priorities straight folks! Also the F-type looks a whole lot better than any new model transformer styled Corvette.
