From your profile you're squeezing as much out of your filthy ICE investment as you can as well? A 100,000 mile + oil burning 2 tonne car? Why don’t you compromise on something other than range if you’re so concerned?

In any case there are far more effective ways of saving the planet than buying an EV.
That's gone, sold a few weeks ago. I'm running a V90 T4 for 18 months on a lease until the affordable EVs become available. It's reduced my CO2 emissions slightly, and my particulate emissions massively.

Think the V90 is Euro6 D Temp... these cars are RDE compliant and they are actually pretty good on emissions.

Anyway, we've derailed this... Back to the Audi...

Those consumption figures look a bit disappointing.

Not sure if the conditions were exactly the same on his other videos when he tested the Model X and i-oace, but I think Bjørn measured the efficiency on the i-pace to around 10% better than these figures. Model X was 15% better.

Oldham Audi said they'll have a car for viewing in mid-March. To be fair this looks quite good value at circa 75k considering the cheapest Tesla you can currently buy in the UK is almost 90k.

Real world range and interior size are going to be the true tests.

If you are going to buy it as a company purchase, it might make sense. But as a private purchase from taxed income, it sounds a lot of money to me.

150kW charging I see - if that's 3-phase 400V that's going to be a hefty cable. Presumably they step up the voltage for 150kW but I can't find any info... anyone know?
I did find that 350kW chargers are now being rolled out in Germany though.
I had a look around a IONITY 350kW charging station recently here in Switzerland. The cables weren't noticeably thicker than 'normal' fast chargers (I believe they're liquid cooled).

The big difference between them and other chargers is that each charger seems to have what looks like a small substation (or storage?)

Looks like it will charge at 150KW up to 80%, very impressive charging speed. Consumption was always going to be bad with such a conservative design, but the charging speed is very very impressive - probably the best EV on sale today, I doubt a CCS RHD Model 3 will do 150KW up to 80% SOC.

Size looks decent too, luggage space is only marginally less than our X, but no 7 seater option frown.

A very good EV by all accounts, I will be 100% keeping an eye on the Audi GT.

I believe the 'post' with the touchscreen, rfid reader and the cable storage bit is literally that, a dumb post. The nearby metal box is where the actual high power electrics live.
Usually the chargers are limited by current capacity; P=IV, so they've got to be closer to 200A than 100A, at ~400vDC.

I do remember seeing that the new rapid charger design from Volkswagen has something like a 30kW connection to the grid and ~350kWh worth of battery storage. So the grid connection can be sized according to the average load on the charger, rather than for the peak transfer of energy into the vehicle. Clever idea, and presumably quite graceful in use; if the battery storage goes flat then your charge rate would presumably drop to 30kW, but then if nobody charged for a while it'd be back up to full speed. Probably works well if they cover a service station roof with solar, or pop a couple of wind turbines nearby!

Charge curve is very impressive

I'm guessing the 3 will taper off sooner on CCS, should start at 150kw I think, but even on 120kw supercharger you get roughly the same range per min as the etron would because of the difference in efficiency.

Bjorn got 370 on the iPace but the heater was broken. I dont think it was in as harsh conditions though.

Funny it looks like both cars have around the same available energy (~82kwh) even though the e-tron has 5wkh more overall.

I think 350 kW through a three-core 400V cable set-up would be impractical without stepping up to medium voltage, so you are probably right about the liquid-cooling. Regular 150kW three-core cable is pretty common, I'm guessing around 120 mm^2 (per core).

350kW is 800v (Taycan is capable)
Even the 175kW chargers are using liquid cooled cables.

Afik most of the 350kw chargers don't yet have the right cable for that anyhow they are limited to 175

The good news is that the Audi passes the longsword test... Just.
