My Zurich Tesla Confessions: 5 Months experience
By Siim Metsla, Zurich Tesla Owner
March 2026 – AI organized my messy notes, but this is 100% my Tesla app data + real experience with my 2021 Model 3 RWD (VIN: LRW3E7FA2MC40XXXX, late Dec 2021 Shanghai build). Survived 5 months without home charging—here’s exactly what worked for me.
My Tesla Specs: VIN Decoded
2021 model year (10th digit M), Shanghai RWD LFP battery (60kWh), heat pump, black trim.
Displayed range: Was 423km when bought (27k km, 4 years old), now 421km (39k km total). Real-world range: 300km winter (-10°C days), 350km summer steady.
VIN breakdown: LRW=Shanghai Model 3 | F=LFP battery | A=RWD | M=2021 | C=Shanghai plant Pro tip: Door jamb sticker shows exact build month.
My Exact Tires: Pirelli Cinturato All Season SF3
No winter wheels—running Pirelli 235/45 R18 98Y Cinturato All Season SF3 Seal XL TL (4 wheels).
Full swap + recycle old tires at Bosch Service Centre: <1000 CHF total.
Efficiency: No noticeable difference vs summers (few Wh/km only).
Pressure: 2.9 bar summer/winter (drops to ~2.7 bar cold, rises to 2.9 bar driving).
Snow grip fine for Zurich Oct-Apr legal requirements, rain king, barely louder than summers. Road surface matters more than tire marketing hype.
Winter Heating: Smart Minimal Use
2021 refresh heat pump system—super efficient but I rarely use most features:
- Steering wheel: Auto <15°C , rarely notice it on but when it is, really feels nice
- Seats: Only when really cold when stating driving.
- Rear windshield defog: Most used—keeps back window clear (Model 3 has no rear wiper!). Uses some extra energy but worth it for visibility
- Max cabin heat: Only extreme cold when deicing, prefer seats. I also open back windows time to time when on long drives as air tends to becoming try inside small cabin. Thinking already about next gadget to test: Ionizier. 😀
Cabin temp strategy: Pre-heat 2-3 minutes before leaving → arrives perfect temp instantly. Mostly I am using Auto but Manual on long trips when there is long tunnels, example driving to Milan, prefer manual for inside air option.
Drive: 18°C winter, 21°C summer AC (minimal energy drain).
Partner’s dance class bonus: Waiting for her for 2-3hrs with heating/AC on (even if I prefer to with in Tesla lounge when charging) = barely notice energy drain. Will see with summer AC. Netflix/YouTube/browser works great even if little slow with older Intel browser to open (never thought I’d use car for watching Netflix). Just bad there is no Grok to talk with! 😀
My No-Home-Charging System (5 Months)
Rule: Charge where I already go—gym, forest walks, shopping. Never detour 15+15min to Tesla Superchargers. Cost irrelevant (even with 30% premium)—convenience and time savings wins.
Zurich Charger Reality (Real Costs + Speed)
| Location | App | Speed | Price | Notes |
|---|---|---|---|---|
| Work Sundays | QR code | 22kW→11kW real | 0.15 CHF | Best deal! |
| EWZ Zurich | SwissCharge app | 22kW→11kW real | 0.50 CHF | 4h limit! |
| Energie 360 | SwissCharge cost less | 50kW→25kW real | 0.59 CHF | Less than 2h full from 20%. 2h limit! |
| Shell | Shell app cost less | 22kW→11kW real | 0.79 CHF | Free Zurich Zoo parking bonus |
| Tesla SC | Tesla app | 170kW peak (my M3 21 MY) | 0.56 CHF | In future, Road Trips only |
QR scan → Debit & Credit payment options, even Apple Pay/Twint. No charging cards needed.
Daily Routine (Zero Range Anxiety)
Morning forest walk 1h: +20& while walking (+84km displayed)
Gym 2h (walk there = warmup): Arrive → Leave +40%
Shopping 30-60min: +10/20% charged
Result: Always topped up, never think about range
Current avg cost: Little more than 0.40 CHF/kWh (Supercharging mix + cheap work Sundays). Target less than 0.30 CHF with home charging parking place in covered open garage parking.
Winter Tesla Supercharger charging: Cold battery = 40-70min full charge. Last 10min = calibration. Precondition 15min helps.
Arrival buffer: 20-30% default (safe for battery). 10% absolute minimum even with plugging in right away after trip.
Trip hack: Add Supercharger to navigator = auto precondition. Skip for extra shopping time.
Perfect Zurich Cycle: 70-80% → 50% Daily
| Start | End | Real Distance | Why Perfect |
|---|---|---|---|
| 70-80% (295-335km displayed = 230-280km real) | 50% (210km displayed = 175km real) | 80-120km | Covers ALL Zurich driving |
Example: Start 75% (315km displayed = 260km real summer) → drive 50-80km → end 60% → gym charge → repeat.
Garage Charging (New Era)
Finally! Will Schedule 10pm-6am off-peak → 80% daily limit.
Curious: Will I see average cost drop to below 0.30 CHF/kWh? when I battery will be always topped up by default.
Near Future routine with home charging:
Daily: 65-80% (230-280km real range)
Weekly/Biweekly: 100% Friday night → For usual Saturday road trips
Longer Trips: 100% hours before leaving
Idle for long weekends / weeks: 50-70% (lowest stress to battery)
Vampire Drain? Laughable
Max 1%/day cold, <15% total over 2-week Christmas holiday (parked on the street!). Latest update + LFP = sleeps perfectly with no noticeable drain. There is even “battery saving mode” option now that I can always keep on.
Battery Health: Supercharging Didn’t Hurt
5 months heavy DC fast charging: 0.5% loss (423→421km displayed).
Real range: Minimum 300km winter, 350km summer steady.
Cold—summer should show +10-20km displayed. 1%/year normal for LFP.
New: ~430km displayed → 4 years old: 423km →
My 5 months: 421km LFP laughs at frequent 100% Supercharging
Next 6/7 months: Will I get few km displayed range back with warmer period driving?
15-20 More Years? 100% YES
20k km/year habits:
- 2046: ~240k km total
- Displayed: ~350km (75% health)
- Real summer: ~280km (plenty for Zurich)
Still can arrive Milan that is 280km away without charging! - Drive unit: 500k+ km easy
- Brakes: Regen = minimal wear
Zurich-Specific Winter Tips
- Pre-heat 2-3min before leaving (arrives perfect)
- 18°C winter cabin, 21°C summer AC = minimal drain
- Rear defog always = clear visibility (no rear wiper)
- 20% displayed buffer = 60km real safety
- Pirelli 235/45R18 All-Season = <1000 CHF Bosch Service Centre
Curious to see how many km they last, guarantee is for 2years and minimum 4mm.
Got to be part of a 40 CHF cash back campaign for 2026 Swiss Highway e-vignette! - Tire pressure: 2.9 bar (2.7bar when was very cold → 2.9bar when driving)
Key Takeaways
- Pirelli Cinturato All Season SF3 = winter/summer/rain champ
Also used with my previous Toyota Avensis & was confident when ordering. - Gym chargers = free range during workout
- No detours—charge where you need to go anyway
- Rarely use seat/steering heat—saves on range
- LFP don’t mind frequent Supercharging (0.5% loss proves it)
- Displayed ≠ real (421km = 300/350km even winter)
- 70-80%→50% cycle = battery immortality
- 20-30% arrival buffer = bulletproof
