Atto 3 - claimed range vs actual range

There is a setting where you can change to Dynamic range calculation which would show you the range based on your consumption. This 480km is a NEDC range which is done in very light conditions. WLTP range for this car is 420km which is more realistic but still done at the optimal temp and with lights, radio and A/C off. The realistic range is usually 80-85% of WLTP.

Freeway uses more range than city driving too

The first thing to do is to ignore the range estimate on the dash. it's completely rubbish. Swapping to dynamic range estimate helps a little but it's still a massive lie. After a while you'll get used to thinking of trips in percentage of charge. Kinda like the entire quarter of a tank for that trip thing. I'm based in Gippsland so everything is highway driving for me. Almost 40,000km and 14 months in and I can tell you thayif you assume 300km of real world highway range you'll be all good. My Melbourne trips necessitate a quick 5-8min charge on the way home around 90% of the time. When I'm in the city driving around suburbia I could see the car easily hitting it's 420km WLTP range. The difference between consumption is around 14kWh/100km in the city and 18-19kWh/100km on the open road. I do a pretty regular run between Gippsland and Mornington which is roughly 260km. in summer I'll get home with around 25% remaining, on the coldest winter night with temps around 4C @9pm I got home at 12% remaining.

EVs when going over 80km will tend to drain the battery much faster - it can go up to over 20kw/100km and even higher when you have the aircon on. However if you mostly do city drive at 60km/h or under, with a lot of stop / start it can be as low as 11kw/100km.

My 2023 Atto 3 Extended range. 300km@110kmph. 450km@60kmph. Basically at highway speeds 1% = 3km.

The US EPA test is the closest to our conditions. If you google WLTP to EPA, you'll get an online calculator which gives a better indication. EVs get their stated range in city style driving. High speed hwy driving costs more energy/km than slower driving, so you'll get less range. It's still going to be cheaper than putting fuel in.

Yeah this is all you need to know. Whenever I'm on road trips I just times the battery % x 3 to get the range. I usually end up slightly better off so it's a nice safety net if it happens to be windy/raining or cooler weather.

Whatever you do don’t drive in Sport mode, your range goes down to about 200m

BYD customers have complained about the inaccurate range readings. I own a Tesla model 3 LR and the WLTP is 629km. My driving style and around my area im getting more like 520-540km. If I drive like a snail it bumps up to around 580-600km. I actually find on the highway drives about 170km return, I average 90-110kmh speeds and get slightly better. Might be wind dependent. If I can cruise behind a truck the range is awesome as you get the slipstream.

Have once seen over 500 in a week of ideal conditions, only pre cooling air con once and no use of heater at all, driving mostly 60 and 80 zones. Normal for me is low 400’s but I am barely doing 30% motorway. Was on track for under 300 (likely 280 or less if I pushed it down to 5%)on one trip that was all motorway with heating and demister on the whole time.

I used to drive in eco thinking I would get more range, literally no loss of range in sports mode. Also found I lost significant range using high regen

Oh, totally the opposite here, on the motorway, looked down on my normal route and it had dropped to 4%, when I should have got home with 20% ish, had to find an emergency charger

I too get better range in sports over eco. Might have to try standard regen as well.

I’m a remote rural driver and for me 10% = 33km in my Atto. Nowhere near 420 or 480km.

You will never go close to the stated range at highway speeds. Just look at how much usage increases from 70-80-90-100 km/hr. 70km/he seems to be the sweet spot for getting max range.

The dynamic range calculation is drastically inaccurate, but the standard range calculation is wildly inaccurate. Neither is truly based on consumption. Although the dynamic one does change in some way, possibly correlated with consumption it doesn't match the battery capacity divided by the long term or last 50km average consumption.

EV range is best at low speed, city driving you can definitely reach 420km+ even with spirited driving. If you’re on the freeway, that just goes down as with any EV.

Electric Viking on YouTube recently released a video about this. Takeaway is BYD is a bit inefficient at high speeds.

Just change your range left from KLM to % and live life happily

My personal experience has been that EV efficiency tends to drop off precipitously after about 100 km/h. Driving the same mileage in central London vs the countryside the battery barely goes down 1 or 2%, but it drains quite faster in the country.

It's the inverse of ICE cars basically.

Anything that uses the battery will decrease the range. Lights, stereo, air conditioning, charging your phone etc. Claimed range uses professional drivers in daylight in optimum conditions. Claimed range is not real world range.

Seems like your car battery is degrading at a very rapid rate if that reduced range has occurred from only 1200km

Test drive a Tesla on the same trip. Tell me what the tow truck service is like on your way back. More to do With how every Electric car company bases range calcs on coty driving at 50/hr

Is the claimed range 480km WLTP? This is what a lot of people miss. WLTP stands for “Worldwide Harmonised Light Vehicles Test Procedure”. It is a test done in a laboratory with exact tyre friction, exact windage (ie none), exact heat, etc etc so that all cars can be tested under the exact same conditions. It was never meant to indicate real world range (this is what a lot of EV-hater people and journalists get wrong). WLTP is just a way to do testing in the exact same conditions whether you are in a really hot hilly country or a really cold or flat country. It allows the consumer to compare like-for-like under specific conditions. It would be stupid to have one car company in country A give range estimate in sub zero conditions and another company to give range estimates in +40c conditions, the same car would give wildly different results.

WLTP is not indicative of real world driving range. Common mistake.

Ofcourse it isnt. But common feedback from BYD owners is the conversion of real workd range to WLTP is worse than with other brands. ATTO 2 and ATTO 3 particularly from what I have seen lately. Its interesting to understand the subtle variances between brands, even where range/kWh battery size are similar
