Hybrids - MPG
« on: 05 April 2021, 22:53:39 »

I keep glancing at auto trader and simply being nosy started comparing Hyprids.

BMW 7 series
Porche Cayenne/Panamero
Volvo
Mercs

All in the 100/120+ Mpg even one mentioned 200mpg (cant remeber which)

Even the Range rovers. 2.0 engine all arround the 400bhp mark

We know these cars go like the clappers but what do they actually return in realistic MPG figures.

Does any one own a Hyprid.  If so how do the paper figures compare to real driving?

I'd guess that it's totally dependent on what type of driving you do. If you have a plug in hybrid and never exceed the battery only range, then the fuel consumption will be next to nil. Use it on lots of 100 mile plus motorway jaunts and all you're basically doing is hauling a load of heavy batteries around for no good reason.

For most people it will probably be somewhere in the middle.

I've only ever had a pure EV, never a hybrid.

EV would not be worth it for me.  If I invested in a Hybrid then the idea would be that the saving on fuel would pay for the car.

Typical regular trip would be Aberdeen and back 800+ miles

Holidays, Corwall would easilt be 1000 miles 350 there, same back plus visiting places.

With the economy maybe trips through frane.

22+ mpg etc versus 140 mpg  has got to be looked into. :y

From what I've read, the figures you are quoting are for plug in hybrids that rarely actually use the engine.
From What Car:
Toyota Corolla Touring Sports 1.8 VVT-i Hybrid. Test MPG 49.4mpg. ...
Toyota Yaris 1.5 Hybrid. True MPG 49.2mpg. ...
Hyundai Ioniq Hybrid. True MPG 46.9mpg. ...
Lexus ES 300h. Test MPG 44.7mpg. ...
Honda CR-V 2.0 i-MMD Hybrid. Test MPG 43.3mpg. ...
Toyota RAV4 2.5 Hybrid 2WD. Test MPG 42.3mpg. ...
Toyota RAV4 2.5 Hybrid. True MPG 37.1mpg. ..

My astra 2.0 diesel beats the bottom four.

All the cars I looked at had engines, but I never gave it a thought that they might manipulate the reslts to look good by just using it on plus in power.. ::)

Maybe it's about time they revised the stats on Autotrader to give a more accurate idea for the consumer. :-X

No, 23.4 is what i seem to get average at the speed limit or less your honour  :P
an Omega full of tools and junk and a 14 stone fatty at the wheel is never going round a track fast

I do mostly 50 to 70 MPH ,20+ mile runs , not much round town or slow driving once i'm out the village

It's not as if manufacturers lied about the economy of traditional ICE cars. Sorry, not lied, but quoted figures from entirely artificial tests done under laboratory conditions.


Car magazines that did proper tests always quoted their actual mileage.


A self-charging, short range hybrid is never going to beat by much the mileage of a car that uses all the fuel to drive itself. Small increases are possible if the car is used for the cycles that it is optimised for. That optimisation is not easy, because you also have to work around the extra systems. This sort of hybrid is intended to spend its life in inner city heavy traffic, where the engine isn't used for creeping along slowly. That's a realistic use for such things, but they're not the complete answer that they were hailed as 20 years ago. Which anybody who has actually driven in mixed traffic conditions will know already

Its simple maths really, you dont get out for nout ! when in engine mode not only do you have to generate energy to drive vehicle you also have to generate energy to charge battery pack and it always takes more energy to charge than you get in return. Laws of physics and all that.

The BMW i3 carries enough fuel to give an extra 50-60 miles of electrickery. Around a third the capacity of the batteries if you are trying to use the batteries as you charge them... (the engine is technically a generator as it only charges the batteries).

Not all i3s were equipped with the engine; they were available as plug-in only EVs. Which were so much more popular that BMW stopped selling the range extender. If you're expecting to use the range extender then you have to ensure that the tank(which is tiny) is full. Which is no different to running out of LPG and realising that the petrol tank is empty too

There's a certain logic to that although it does then restrict the usage of the car somewhat.  :-\

Any plug-in EV is severely compromised if you're intending to use it mainly for long trips. The i3 is intended mainly as a second car, or as a run about. It helps to have fallen for BMWs advertising.


I've driven one and while the electric part is as beguiling as it always is(especially in a small car), the BMW-ness is just as off-putting as ever: terrible suspension, weird design decisions and engineering for the sake of it. It was always going to be a loss-leader; getting customers to demonstrate the bugs in the drivetrain that is now a production option in Minis, and a toe in the water for building production carbon-fibre monocoques. Don't expect to see those any time soon.

The best feature of the Range Ex i3 is that it allows you to use 100% of the battery capacity on any trip.

The main issue with shorter range EVs and the UK'S currently sub-par charging infrastructure is that you inevitably want to save 20 of your 100miles in case you can't charge when you get you're going. The i3 allows you to use all of its battery range every time.  :y
