2016 Prius MPG from cold start
Discussion
Just wanted to share, in case it helps inform others.
I left my house one afternoon last week and had to drive for a client meeting, lots of 20mph zones and speed bumps on my way into the centre of London.
The car hadn't been driven since the night before, so the engine was cold, although the battery was mostly full. I normally get 60-65mpg at the moment, but was surprised to get 77.8mpg.
Probably because I didn't have the heating on, since I was wearing quite a few layers.

Do you have the 15 inch wheels or the 17 inch?
I have the 17 inch wheels (Excel version) and in similar circumstances I get about 70mpg. Average economy, in all conditions, is running at about 63mpg.
I have to say, it's a really impressive car. Very happy with mine.
15 inch wheels (yay, no congestion charge!) - Business Edition and I'm looking forward to 80+ once the weather gets warmer next year. Yeah, it's significantly superior to the previous version of the Prius. Actually goes round bends reasonably well even on 15s!

So is this the standard hybrid Prius? Not the plugin? Those are very good numbers if so. Are they born out when you calculate from the fill up?
They made some good efficiency improvements on the ICE in that car as well, looks like it paid off.
Yes, standard Prius, with about 3,000 miles since new. I find the computer in the car overstates fuel economy by around 10% vs what figures I get when I calculate brim to brim by hand. They made some good efficiency improvements on the ICE in that car as well, looks like it paid off.
My last tank which was mostly motorway miles, with quite a lot of ICE usage due to overtaking of lorries etc, and that was 55mpg hand calculated figures. I used to have a Type-R and looked forward to the open road and getting up to near 8,000 rpm.
Now I look forward to slow moving traffic to watch my MPG rise as I stay in EV mode. How times have changed
ADAC's testing of real world emissions is really interesting. They rank the Prius above the Leaf, but below the i3!
And the latest diesels perform badly.
I suggest using Google Translate to read the report

55 on a run is good, perhaps a little lower than I thought, but not by much.
For reference the best I ever got out of my 1.8 civic was a proper 50 mpg on a trip to Scotland. A one off though, usually it gives about 45 on a run and a 35 AVG.
My newer car, a new Mazda 3, is a 40 AVG but you can quite easily get up to the 50 mark on long runs.
So the Prius is a good 10% better there. Interesting that on occasion, the two cars I have with 10 years in age difference, give similar economy.
I tend to drive fairly rapidly on the motorway, and leave it in power mode, so it would be more likely to use ICE. I have noticed if you are gentle on the gas pedal, it can dip into EV mode even up to 74mph. If you do mostly motorway driving, the Prius does not make sense at all.

It's best for congested cities like London, imho. I've read reports of US owners of the Gen 4 Prius getting 800+ miles out of a 43 litre tank, and I suspect it's a combination of driving in warm places like Southern California along with with very gentle use of the gas pedal.

When you calculate mpg how do you measure distance? The car can read about 10% extra if youre not careful
I reset one of the trip computers on the dashboard to zero when I fill up. Next time I fill up, I refer to that number for distance travelled. Edited by saaby93 on Tuesday 27th December 22:42

I don't really agree, although my car is the older technology (it's an Auris). Driven in exactly the same way on the motorway as my previous car (Skoda 170 TDI), it's more economical. Admittedly, if I start driving quite fast, economy plummets quickly, as did the diesel, but I just sit on cruise at 70.
I spend most of my life on the motorway, if anything, my car is worse in town than on the motorway, although it really depends on traffic and route.
Interesting. The new Prius may be quite different than other older Toyota Hybrid technology then as my recent motorway journeys are getting between 50-60mpg, yet my urban use is giving me between 65-85mpg (now the weather has warmed up a bit)I spend most of my life on the motorway, if anything, my car is worse in town than on the motorway, although it really depends on traffic and route.

We are seriously thinking about changing our 2015 model for a new one in the next few months and making it the family car a role that's currently undertaken by my Octavia
For those that have done the same is the in car entertainment a significant improvement , i find ours to be diabolical?
The in car entertainment is the oldest part of the car's technology, when you compare how it works and what it offers compared to any other mainstream brand which makes a similar size car. No Apple Carplay, no Android Auto and even though mine is the Business Edition model, the voice recognition feature is disabled (you have to buy the higher models)For those that have done the same is the in car entertainment a significant improvement , i find ours to be diabolical?
The owner's forums in UK/US have the same complaints, and the factory sat nav isn't particularly great either.
I've done 6,500 miles since new and the on board computer shows fuel economy of 62mpg as an average over those miles, which is probably 59mpg in reality given that my own calculations show the on board computer tends to be around 5% optimistic.
After 8,500 miles my 2016 Prius is returning some great MPG.
The temperature has risen recently and I've got my best tank ever. Ambient temperature seems to make a big difference to fuel economy.
AC has used on every trip too. Mostly urban traffic in London but I do a fair amount of cruising on A roads at 40 and 50mph too.
Dashboard shows 74.7 mpg - I filled up a few miles after the low fuel light came on and the actual mpg comes out as 70.3 mpg
So I paid 7.3 pence per mile on this tank in petrol costs. The dashboard is 5.9% optimistic for this tank. I drive into central london before sunrise most days and on those trips, I'm now getting 85-95mpg shown on the dash.
Given a 43 litre tank and another 7 litres left at the time I filled up, then I would have in theory been able to drive another 105 miles until the tank was completely dry. That would give a range of 662 miles.
