What's the fuel consumption for everyone?

Someone reviewed a Q30 Sport 2.0T 7DCT 4WD and 28.8 mpg instead of the 45.6 mpg Infiniti claims it has and this was in favorable conditions. That's 37% decrease than what Infiniti claims.

I suppose you refer to Neil Winton’s review, in which case we’re talking imperial mpg, well, for a 2 liter petrol engine driving a 4WD, I would say that 28.8 mpg is about par for the course.

As regards mpg manufacturer claims, I don’t even bother with those, at a stretch, since all carmakers grossly overestimate the mpg (on the basis of absurd test protocols), I may use their figures for comparison purposes just to get a rough idea about which cars are thirstier or more sober, but that's about the size of it.

So far our 1.6 petrol 2WD with a little more than a thousand miles on the clock, is showing an average 35 mpg, for an average speed of 21 mph, which I consider fair enough knowing how my wife drives (should I dare utter the word “eco-driving”, she would accuse me of being rude to her).

Lol, happy wife happy life.

Yup, the numbers were from Neil Winton’s review. why can't the world just use one form of universal measurement!? Manufacturer's fuel economy numbers are more like guidelines so I don't expect the average driver to get exactly what they list but somewhere close to it. I've read that manufacturers try to remove things from the car to reduce weight and improve their numbers, not sure if Infiniti does this too.

35 mpg seems a lot more reasonable especially if the driver is a bit heavy on the gas pedal. Conservative drivers may be able to get closer to the 40 mpg mark.

It's just the manufacturers get the fuel economy numbers under the utmost optimal circumstances. They probably hyper mile it the whole time too

Most times they don't even put vehicles the sort of environments that real customers will be. So as I always say use the numbers they report as a reference point and wait till the real world numbers roll in, that's where it really gets good and where we can confirm if those initial numbers were helpful at all.

Basically in a simulation similar to a dyno, it sucks but that's how the game is played and how they set the bar for those competing in the industry. After all we're living in the MPG war era.

Yup.. Thankfully the new CAFE standards are getting thrown in the trash with their ridiculous 50+ mpg requirement or some nonsense. I could only imagine how badly the manufacturers would be attempting to scam that

50+ mpg is ridiculous even with the technology at our disposal right now. The number sounds great but something else will need to be sacrificed in order to meet that requirement. 35 mpg is very generous in this day and age unless you go hybrid.

Definitely, somewhere in the 25-28 range and you can have a good balance of performance and efficiency.

50+mpg and I can't imagine them having any sort of decent performance. We may as well go back to K-cars or something lol

(in response to an ICE 50+mpg)

mileage is usually better on motorways when you don't have to constantly start and stop. I think 50 mpg or more for combined use is going to be hard to achieve.

Some figures for those who are interested...

250 mile trip from Bedfordshire to the Lake District, mainly straight A-Roads and Motorways (M1, M6...) - a large portion of which had 50MPH speed restrictions due to roadworks. Doing a little over what the law normally allows where able on the clearer bits of the motorways.... 59 MPG.

Twisty, tight, narrow, hilly country lanes once in the lake district - 50 MPG.

Straight A-Roads, with a little town driving too, 50MPG. Again, doing slightly over what I should be doing on the A-Roads...

Can't wait till full or partial carbon fiber wheels become mainstream and we're able to pick up a set for a decent price, that should help to shave off some MPG's and add bling at the same time.

I've stuck with very similar segments in the past decade and plan to for another decade, so buying a set of wheels will last me at least the life of 2 tire sets.

50-59 mpg is actually very good for crossovers.

If only carbon fiber wheels were cheaper...alloys are okay too but I'm in Canada so a set of heavy steel wheels will be needed for winter. That's going to cut down on fuel economy.
