Hi, I currently drive an A8 50TDi but I'm considering changing to a Q8 e-tron 114kWh Black Edition.

Audi state a range 333 miles but what is the real world range for different scenarios, any info is greatly appreciated.

Cheers.

I'm in the US and have had a Q8 e tron Sportback since July 2023. The EPA numbers, I find, are pretty close to the actual max range: 285 mi for the SUV, 295 mi for the Sportback. 333mi is WAY too optimistic. That is at 77F temp. At 40F the range drops into the 250 mi range at 100%.

I think he’s in the UK, or somewhere that uses the UK MPG system. 1 US MPG = 1.201 UK MPG, while 1 UK MPG is 0.8327 US MPG

Apologies, I should have said I'm in the UK.

I'm spoilt with the A8 has it has Tour pack with the larger fuel tank and regularly average around 600 miles before needing to refuel.

I just need some assurance I'll not be stopping every few hours to charge the batteries waiting for an age.

I'm new to the EV table so apologies for the simpleton questions.

During my road trip from Ohio to California and back, the average wait time to charge was 20 minutes. The E-tron has a pretty decent charging curve so it does not take that long to replenish the batteries.

count on 250 miles between charges on the road trip +/- 10% depending on how you drive and battery temperature.

Here's a link to the charge curve for the Audi Q8 etron ... https://evkx.net/models/audi/q8_e-tr...chargingcurve/

My thinking is... charging over 80% becomes quite slow (and isn't too good for the battery), and driving until your charge is less than 20% is scary (and also not very good for the battery). If you drive till the battery's down to 20% and then charge to 80%, you're 're-filling' 60% of the battery's total capacity, or about 63 kWh. If you're getting about 2.8 miles per kWh, then your effective range is 176 miles. For peace of mind, I plan my charging stops about 175 miles apart, or less. I may make more stops along my trip, but each charging session is at a mostly optimal charging speed. And I'm retired, so I need a break every 2-3 hours anyway.

Very interesting, in 30 min of charging from 10% SOC you can replenish 71 kwh on Q8 vs 67 kwh on old e-tron, that gives you 213 miles of range on Q8 e-tron vs 201 miles of range (assuming 3 miles per kwh - not many can do this) on old e-tron until next stop @ 10% battery SOC. so old etron faster charging speed makes up for the smaller battery during road trips and doing 30 min stops.

Q8
10% 133 kW 5 m 13 s 10.6 kWh
77% 116 kW 35 m 15 s 81.6 kWh

vs

Old e-tron
10% 138 kW 4 m 30 s 8.6 kWh
88% 86 kW 34 m 50 s 75.7 kWh

That range is no doubt from the EU, WLTP(?) range estimate which is always overly optimistic.

The US EPA range estimates are very reliable I believe, as long as you realise that they only represent best case scenario vis-a vis ambient temperature; absence of headwind; average speed, etc.

I'm not sure how much of your journey takes place on the Motorway, and what your average MPH would be, but there is a big difference in 'consumption' between 70 mph versus 80 mph.

If you leave home with 100% SoC in decent weather and temps, you'll be looking to recharge as others have stated around 250 miles later. Your quickest journey from then on is to arrive at a DCFC charger with about 10%-20% SoC left; rapid charge to 80%-90%, and hit the road. Getting to 100% is generally counter productive as it takes far too long to squeeze in that last 10%-15% of charge. Caveat: occasionally it is worthwhile charging to a full 95%-100% IF it means you can skip an additional stop for a quick 'top-up'.

There are excellent resources/apps such as ABRP; Plug Share, etc. (which I think can be used within the UK), that you can use to estimate where your charging stops should be for any given long journey outside the range of the Q8 etron.

Good luck with the purchase, I loved my '19 etron!

PS: you do have access to a home based L2 charger, yes?

As a former 2019 and current 2024 e-tron owner, I would agree with everything that's been said in this thread.

I have driven the car in pretty miserable conditions (-20C, dumping snow, etc...) and the range definitely takes a hit. But the 2024 overall will get about 50-75km more range than the 2019 even in these terrible conditions.

Charging when cold is slower than the outgoing model - that's been a bit frustrating. But it's still relatively solid overall and manageable.

In the summer the range was consistently around 400-440km (about 250-275 miles) depending upon how aggressively I was driving it.

I will also echo the comments about speed: for every 10mph over about 55-60mph, you'll see easily a 10% hit on range. Not surprising given the laws of aerodynamics

gvbell's comment about the 20-80% useable part of the battery is a pretty good rule of thumb for road tripping. Of course there are many who want to drive the car down to 10% SOC or less, but ask yourself if it's worth it when your spouse is in the car to drive a ICE car down to Empty before filling up. Usually the "bing bing" of "low fuel" will get people agitated: this is even more true in an EV given their current range and the limited (but evolving) charging infrastructure.
