Re: i3 94ah range at highway speed

Mon Feb 20, 2017 5:27 am

So I had a long trip to do today and thought I would give it a test run for you. It's been really foggy so I was on cruise at between 52-55mph all the way and just let it run on EV. Comfort with lights on all the way and it was between 10-12c ambient temperature. I had to charge on a public charger first but only got to 97.5% SoC before I left.

Here's the result when the Rex kicked in :D

With the extra 2.5% SoC I probably would have made 132.1 and with the 6.5% reserve added around 137 miles

Wow fantastic range, thank you so much for the detailed feedback. ;)

Really, in similar conditions I only get 60-70 miles in my 60ah. I was skeptic of such big change but the 94ah is indeed a BIG improvement. :o

Just traded my 60ah i3Rex for the 94ah Rex. I do a 42 miles each way commute, of which half is at 70mph on active cruise control. Range is up by at least 50%, probably slightly more.

As all the commenters here have said, your local conditions make a big difference. Temperature, wind, speed etc. Bottom line is I could rarely get more than 80 miles off the 60ah model. As I write, the stated range on the new car is 133 miles, which is about 25 miles more than the worst reading I have had. I would say a 100+ miles journey at 70mph is way too tight for a non Rex car.

The Rex gas tank equates to about 21kWhrs. Multiply this by the miles per KWhr you would expect to get on different journeys and you will have the rex range.

Any new info? :)

I felt I had more than 50% (actually more like 60%) when I tested a 94ah in my usual situation.

The 94ah has consistently exceeded my expectations, and reminded me that I am not the most economical driver. What I can say is that my wife took the car to work this morning, and the statistics on the BMW App are astonishing.

Distance 41.6 miles
Consumption 5.3 mi/kWh
Duration 1 hr 16 min

Electric range remaining: 121 mi / 77%
REX range: 100mi
(full tank)

That's indicating a range of over 160 miles on electric alone, 260 miles combined. If I knew how to do it, I'd post the screenshot from the BMW App as proof!

Preconditioned before I left for work this morning

And after I had done my 22 mile commute

Mighty impressed with a 171.5 EV range :D

Blimey. That's impressive. I'm not going to say you cheated, nor indeed that you must weigh less than my wife. Better stay quiet.

today i tried running REx for 25miles in the highway. i had to hold the charge from 58miles remaining.
punched the throttle, 75 and even 85 but not constant. im fast and yes running illegal speed limit.
as soon as i am near in the office i went back to battery mode and it charges my battery from 58 to 64!
Crazy awesome!
