True mpg 1.8 Corolla hybrid 16 inch wheels

I'm assuming when you say forcing you mean by using the EV mode button?

No, I'm talking about deliberately lifting off the accelerator pedal to get the car running off the Battery when it otherwise wouldn't do it itself. EV Mode is known to be bad for fuel consumption and I suspect it's the same regardless of how you force the car to run on electric. I think pre-empting it is fine rather than waiting for it to realise that electric mode makes sense. But I think making it go electric when it otherwise wouldn't have done so isn't a good idea.

Toyota have put a lot of thought into the control system and they will have picked appropriate thresholds for switching to/from electric mode. Trying to override those is basically driving the car in a way that Toyota don't think is best. Of course the car doesn't know about the dip in the road a hundred yards in front and by the time it detects it might be too late to do anything so it makes sense for us to help out. But on a flat section of road if the car doesn't see the need to go electric then I think leaving it alone is best,

I've been trying to follow the accelerator guidance and mostly it makes sense. The closer you follow it the better your score for whatever that's worth. Last night after driving home from golf (about 8 miles, mostly open road) I actually got 97 when I parked the car in the garage. Highest score I've ever seen.

But sometimes the guidance makes no sense or else is impractical. Most mornings when I pull away from my roundabout onto the main road the guidance bar only extends to the end of the EV range. Well no way am I going to accelerate away from a roundabout on a main road using just EV. A couple of days ago though it suggested full ICE so I don't know what was different that time. In both cases I'm accelerating away from 20 mph so..?

Other times it seems to follow what I'm doing. It'll suggest 'a bit of ICE' and you give it a bit of ice then it suggests 'a bit more'. The more you press the accelerator the more it suggests.

Ah ha! Sorry to spam the forum with messages but I found that thread. For some reason Chrome isn't showing it in my history on my work machine. Odd that. I thought all your browsing history was shared across all devices.

Anyway here it is. Enjoy.

If you can follow it for long enough there's some very in-depth technical information and calculations there.

Hey guys, I'm thinking about switching from a Focus 1.5 diesel estate to a Corolla 1.8 hybrid sports tourer.

 

Being a field engineer we are on the motorways quite a lot. Has anyone got any real world mpg figures for mostly motorway driving?

 

Thanks in advance 🙂

400 miles, 30 litres. 60.6 mpg. Car claimed 63.7. Pretty good. I've got a long trip next weekend so I'll finally get to see what it's self-claimed 70 mpg really means.

411 miles, 30 litres. 62.2 mpg. Car claimed 64.3. The long trip never happened but that's very nice for a tank of commuting.

Hi,

Anyone do a long motorway trip to see what the mpg is?

Thanks

I've only done one in my 1.8 Excel(*) HSD so far. At the end of the long run I think it claimed over 70mpg but after spending the week driving to/from golf courses in the area it was claiming mid 60s and when I filled up it was high 50s.

However I'm due to repeat the long journey and back this Friday so we'll finally know what a 1.8 Hybird HSD can do when driven for 360 miles at 60 mph (I usually drive motorways in lane one with CC set at 60 mph) as I'm not intending making any local trips with it while I'm there.

Interestingly it does seem to be more economical at 60 than at 50. It's only an observation but at 50 it seems to struggle to ever get the Battery charged to where it wants it. My daily commute (12 miles each way) is at 50 mph and when it's not the sole source of motive power the Battery is always being charged. The only time I've ever seen it 'help out' the ICE is on a couple of steep hills where the alternative is to lose speed.

But if I drive to one of a couple of local golf courses where I can drive about the same distance mostly at 60 mph after fifteen minutes the Battery starts to enjoy periods where it's not being charged. At that point it will start to help out the ICE on gentle slopes or when toddling along on flat stretches of road. It basically acts like everything is 'tickety boo' rather than the somewhat 'strained' behaviour at 50 mph.

The impression I get is that 20 minutes at 50 mph is not enough to get the Battery to where the car likes to have it. But 15 minutes at 60 will do that. The only time I've ever seen the Battery with only one (or indeed no) uncharged bars is when I've been travelling at 60. Travelling at 50 the best I've ever seen is two uncharged bars and then only for a short time.

(*)So larger wheels.

ok, thanks, I look forward to see your results.

I do a lot of motorway driving for work and did not know if I would see any benefit from hybrid since they work best in town/traffic situations.

I drove from Gothenburg, Sweden to Copenhagen, Denmark and back: 629 km (390 miles), 95 % highway, 110-130 km/h (68-80 mph) = 5,25 l/100 km (53.8 mpg UK). 3 adults + one toddler and some luggage. Dry condition and with AC on full time. 17” wheels.

I have a 1.8 Hybrid Design hatchback (17" wheels). Just had a longish trip away with quite a lot of motorway driving. The mpg was not any better than my more usual town driving use. All my calculations so far have been between 60-63 mpg regardless of journey type. I'm pretty happy with those sorts of figures, though.

Well that didn't go to plan. Roadworks in various places (don't anyone go anywhere near Abergele!(*)) meant my usual route wasn't available. But nonetheless despite diversions and inclement weather the car has done well. I rarely exceeded 60 mph and used CC on the motorways but 370 miles, 26 litres is 64 mpg. Car claimed 68.

Although very irritating the Abergele experience was interesting. An hour spent dribbling along at 3mph (when we were actually moving) would normally kill mpg. But amazingly the Corolla managed to maintain a displayed 68 mpg. It'd drop to 66 when when ICE kicked in to recharge but then the subsequent electric running returned to 68.

Oh and I once again saw the weird behaviour of ICE running, Battery charging and electric motor providing power to the wheels. I assume there's a good reason for it but it seems rather odd.

 

(*)This is, of course, generally good advice anyway but in this case STAY AWAY FROM ABERGELE EVEN ON THE A55. Oh the humanity!

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
