Fuel consumption at cold during first phases

You are seeing this at 40F?

We see decreased fuel economy at -20F for certain.

 

welcome!
.78 gallons in 3 minutes? edit: sorry, read that wrong. one hour? that sounds reasonable.

sorry to say, but consumption sounds about right. short trips are a killer, but much worse in a gasser.

 

40 f or below, takes 3.5 minutes for ice to stop when starting engine from cold soak. Avg mpg loss around 5 every cold mornings

 

It seems normal

 

leave a little earlier, and take the scenic route. it will use more petrol, but your mpg's will go up.

 

Your stress level will decrease, too.

I find that true, especially since the mothership moved to Plano, where the traffic's gotten a little insane.

 

Yes, cold affects it. If you turn your Climate Control OFF, it may not start the ICE - otherwise it's trying to warm not just the engine, but you too.

The warm up process takes a short-term hit on economy. It's summer here - our temps are about 30-35 C max at the moment (I think that's in the 90s F). The first 12-15km of a trip seems to not be as good as distance beyond that.

A typical 21km trip I take:

• I start off from home, my first 1km show 0l/100 (zero) - as it's a bit tortuous and can't really get any speed up and it stays in EV - at this stage, battery shows only 2 bars;
• The ICE starts, then after 4km as I pull onto the Motorway it is showing 6½-7l/100km;
• 10km along Motorway (total trip now 15km) it shows 4.8-5.0l/100;
• another 5km along Motorway and 1km through back street - at the end of my journey (total trip now 21km) it shows 3.8l/100km.

Return journey - similar.

 

Sorry to un-reassure you but by 10 miles you should be up near 60 mpg(UK) easily. I do lots of short trips and before I retired last year my commute to work was only 3.5 miles each way and the worst I got in winter was around 43 mpg on the trip computer.
As I'm pootling about nowadays a round trip of say 7 or 8 miles (at 40F) will get me up in the high 50s or more. Once the engine is warmed up enough I'll go to mid 60s, this is with the heater on.

 

is okay.

 

47 mpg UK is only 38 mpg US, 56 mpg UK is 45 mpg US, I would say that's low for a Gen 4, on a 24 mile trip.

 

you can't compare your stats with another driver, there are too many variables.
if your mpg are 'low', you must find the cause, which is not necessarily the car, but might possibly be a part of it.
the many external factors include weather, climate, topography, amount of starts and stops, average speed, top speed acceleration, and others.
as for the car, tire size, pressures, tire make and model, air and cabin filters, oil level, can all be factors.

 

Hello from Cornwall UK. I have a 2016 Business Edition also and there is a high demand for fuel in the warm-ups and short trips of less than 5 miles. I wonder if your driving style has an impact and what temperature you set the heater at. Certainly, I would recommend you leave the car to decide when to activate EV, but if your tyre pressure is slightly higher than the book recommends you should have got better mileage over a 24mile trip. Can you say where in UK you are - your county or nearest city would be enough?

 

I have heat set to around 21 deg C which gets a good score on the summary at the end of a journey.
Ideally heat off, at least +5 psi in the tyres (some go even higher) and use the econometer on the MFD to achieve great mpgs.
I feel that the ICE seems to warm up quicker when the heater is on.

 

If the heater is off, the ice stops at a lower temp, so less fuel used

 

I set my heater to 18.5°C on cold mornings. You'll still get heat once the ICE warms up and can increase as necessary later. South Wales is as far north as I seem to go these days, so perhaps that's why I never need more than 20°C . Well, that and the fact her ladyship prefers the car to be much cooler than I do! I'm averaging 65mpg (UK) ATM with mixed driving speeds and journeys types/distances.
PS, no hypermiling!!!
