176 Wh/km is somewhat on the high side... I have the same car as you and my lifetime average is 156 Wh/km without paying any particular attention to trying to drive efficiently. Aeros on, tyres typically pumped up to mid-40s.My 2020 model 3-LR has 18" tyres @ 42psi cold. Wheel covers off. It has used a run of the mill 176 Wh/km in the 14 months since new.
Without AC on and always driving to the speed limit, I get under 130. But 117 is very good, I don’t think I’ve ever got under 120 for a drive of any length.On the return journey it was warmer and because I was not at 100%SOC regen was available the whole drive. I achieved 117Wh/km.
You admit that you drive in a lively fashion. What do you expect your range to be when you drive in that fashion. I have a Model Y and when I drive locally I also drive in a "Lively" fashion. I like to accelerate to speed limit between red lights as much as possible and yes that effects my range greatly, but I do not give a rats whoo-hoo. But when I have taken 1,200 mile (1,920 kilometer) trips this winter I keep my speed within 5 mph of the speed limit and I can easily go 200 miles (320 kilometers) and use 71% of the battery. That is running at US Highways speeds 70 mph (112.6 km/h) , Climate Control set to Automatic with the Temperature set to 71 degrees Fahrenheit (21.7 degrees Celsius) and on autopilot. If I drive 10, 15, 20, etc. mph over the speed they will not get anywhere need the rated mpg or L/Kilometer...My 2020 model 3-LR has 18" tyres @ 42psi cold. Wheel covers off.

This equates to just 426 km range on a full charge. It is an average of course, but it is a long way below the guessometer's 498km. I tend to drive in spritely fashion and have the TACC set to speed limit +4%. Last week I needed to do a return journey of ~420km with the car parked for two days in the middle, without the possibility of charging anywhere. This gave rise to some range anxiety.
So I thought I would temporarily modify my driving habits to see how the range improved. Plan was to drive at speed limit minus 2kmh for 100kmh zones and at posted speed limit for lower limits like 80kmh. Chill Mode to encourage smoothness and do not overtake anybody. Leave Aircon off, unless it becomes uncomfortable, no heating. Do not use sentry mode while parked for two days as it uses ~6% a day. So by no means being a hyper-miler, just drive sensibly and don't be in hurry.
When I departed the car said it would arrive at the midpoint with 50% charge. I actually arrived there with 60% charge consuming 28kWh and 131Wh/km. A good start to my plan.

After the two day sit, the battery had lost 2%. On the return journey it was warmer and because I was not at 100%SOC regen was available the whole drive. I achieved 117Wh/km.

Out and back average was 126Wh/km.

Ended up getting home with the battery at 22% SOC and the guessometer saying 102km left! Had I kept driving at the 117Wh/km I was using on this drive, it would have done another 140 km (in theory). So 423+140 a total of 563km vs the 426km range I have achieved over the cars life! I knew driving more conservatively would improve things, but I was really surprised by how much.
Here are two drives over the return half of the journey above, completed several weeks apart using the different driving methods.

Average speed was the same on both days. Although one was colder and I would have been using the heater. One trip used 36% SOC whereas the other 51% SOC. A 30% difference in efficiency or thereabouts.
It is all very interesting, but I think I will revert to my old driving habits now.

Flatbed-
I'm interested to kknow what application or whatever else you are using to generate these showing all of the usage information? It is really great.

You guys with newer cars should be grateful for the phenomenal range you get. I have a 2015 P85D and driving at my most conservative in ideal conditions can never see under 190 wH/km so my range is around 340 km actual. I would be over the moon to see 150, let alone 120.

Oh, I’m grateful all right! It’s brilliant.You guys with newer cars should be grateful for the phenomenal range you get.
<200 for a MS is good. These other guys a re talking about M3s I believe. My MS average was 200. My MX ids more like 250/km.You guys with newer cars should be grateful for the phenomenal range you get.

with an average speed in the 70s you sort of expect that.
Not really. As shown, with two trips over the same route, both with identical average speeds in the70s the Wh/km varied from 117 to 159. Most people would not expect 159 Wh/km with avg in the 70s. It is more about the range of speeds used and driving style.
