Range test shows really bad results

[lightboxcar]

The other rather worrying thing is cost.

 

Based on the above, 2.6 miles/Kw = (£0.66*/ 2.6) = £0.254 / mile

*average public fast chargeer rates on motorway service station

So a 500 miles drive e.g. London to Edinburgh ) ; electric fuel cost = £127 !  Of course if home charged the first 160 miles a bit less

We will have to wait for experts review about the performance in reality

Completely agree, only time will tell the true picture, but we're never going to get ICE range for sure with what we have now

That's where things like ZapMap can be useful, esp. if you can stay for a while, as it can show cheaper chargers, and 'Fast' chargers tend to be cheaper than 'Rapid' chargers (I hate whoever decided on this naming convention...).

So e.g. instead of stopping at some grotty services, go into town and park at a nice pub that's just had a fancy charger put in and charge on that while you enjoy a good pub lunch and go for a wander through the village while the car gets juiced up!

Thanks for the really useful info.

You say you started with 100% charge.

And assuming you are never going to run the car to zero percent, and ignoring any 'buffer' the battery may have, and allowing 30 miles safety to get to a service station/working charger, the probable safe max range would be about 170 miles based on your figures and journey profile.

Thinking about if you took similar but longer journey, the fast DC charging is capped at 80%, so the next leg of the journey would have 160miles max range.  Again allowing for 30 miles margin for safety, that would only leave 130 miles safe max realistic range.

Guessing this means on a long motorway drive, frequent charging is needed, at a much higher frequency than ICE refuelling for same journey.

Having to charge every 130 miles would be extremely disappointng to say the least.

Hoping the above assumptions are wrong, perhaps other more experienced members can comment ?

If I am not mistaken Norway Toyota claimed that car goes 30 miles extra when it shows 0% Battery range as a buffer. Thus, must be added the shown range. 

 

Preferably, I would keep charging between %20-%80 if possible for battety health.

But would you want to risk letting it go to 0% Battery on the M25 , M1 or M6 motorways for example.

May be the buffer does not work.  There is a video on this forum showing a car with zero percent Battery, it was still drivable, but seemingly at only about 3 mph !

One question for the people who are delivered. 

 

Do you have this yellow dot? 

 

 

Update: Photo is from Indonesia, fixed demonstration car.

We will check when we receive our bz4x

Where do we find that plate on the car please ?

Of couse I wouldn't and don't advice using car until %0 😊. I just wanted to correct range calculation.

I honestly dont know how you get these trip averages. We drove to Ikea Milton Keynes. Mix of roads and motorway etc. distance 50miles, for the return journey the average speed 45 m/h, top speed 71 m/h and duration 1h. Cool (8-9 degrees) in the morning on the way out and mild on the way back. Windy both ways. Trip average was 3.2 for the morning and 3.7 on the way back.

Undersatand what you are saying, and you are techinically correct.

But if we cannot drive the car to 0% Battery, then we can't include all of the possible range in the actual usable range.

Does that makle sense ?

Thanks, that is greeat to hear, and really encouraging.

Was just basing it on this post above: 

From our understanding, the trip was not the same as yours, it appeared to be one long mainly high speed drive circa 70mph , motorway likely

Yes I agree with u and make sense 😊 I wouldn't dare to drive below %20. 

 

Today my xc90 plugin hybrid showed 36 miles range and I used quite fast finally it only gave 10 miles 😊 then petrol engine took the car so definetely we must leave some safety range just in case.

This car is def best in cities and mid speed and looses efficiency on high speed / long distance. There is a german youtube channel that does various reviews and there do a test (everything the same, but speed) 110 km/h (68.3mph), 120 km/h (74mph) and 130km/h (80.7mph) which covers the speed limits in 90% of all european countries and the differences are drastic. More than 10% changes between increasing exponentially. Not seen a test for this car, but every other car tested is the same. 

If you want to do a lot of highway miles then this may not be the car for you. Or you need to accept that you will be charging frequently.

Living in the South East , we try to avoid motorways as much as possible, and often find the non-motorway journeys actually faster.  And certainly much less stressful....

On a long trip such as Scotland though, it's hard to avoid

Had a look at that Norwegian website they based theior story on.

The worrying thing about such websites with big scary attention grabbing headlines is this:

They all seem to have an absolutely HUGE amount of adverts, all down the left and righ sides, and interspersed with the text of thier articles.

So much so that it almost impossible to actually read the articles.

Adverts = revenue

Scary headlines = attract maximum site visitors

Makes us wonder ..........

When you power off your car this trip average appears on the the HUD screen. It takes few seconds. Don't open the doors.

I think you can also see by pressing the odometer button. I haven't tried that.

The best I have seen is 3.9 miles/kWh when I drive to work to and fro. 30 miles round trip. 10 miles of A roads and 5 miles of B roads.

Yeah I've become very wary of click-baity titles, esp on youtube, as they're usually some sensationalist garbage that hasn't been verified properly or some very skewed opinion presented as fact. People like scotty kilmer and 90% of 'EV news' channels are on my blacklist because of this behaviour.

ya, thats where that trips average came from. On my short commute with mostly city and cross country i been hitting values in the mid 4.x

[Cyker]

That's promising - Too many newer EVs have efficiencies in the high-2's to mid-3's miles/kWh, which is disgracefully bad when the original Kona and e-Niro were hitting 4-5miles/kWh.

If the bz is into the 4's that's better progress!

I feel the real controversy around all this is the useable Battery size. 71.5 useable Battery puts the BZ4X on the roughly the same level as its supposed competitors like the EV6, Ioniq 5, and the MEB cars (VW/Skoda etc) and whether that is actually the case or whether toyota restricted this and potentially "led" people on.

The car is def capable in mixed driving reaching 4.5-4.9m / KW. 

Toyota bZ4X FWD price and specifications - EV Database (ev-database.uk)

EV date base put the Battery as follows. 75kw gross and 71.5 nett. If its 71.5 gross and 62.x nett i would be ****** off. I am more thinking that Toyota restricted the size of the battery we can access at the moment rather than this being a permanent situation. But, we'll see ...

 

quick look at the competitors and the listed difference between gross / nett battery is between 2 - 3.5kw across the board
