Here is an outline of the benefits for the Tesla Model X 100D (2018, EU-spec) with Autopilot (not FSD).
This is a very different vehicle from the Model 3s discussed previously—focused on space, utility, and falcon-wing doors, but with older battery and computer tech.
1. Vehicle & Core Benefits (Model X 100D)
Body Style: Large luxury SUV with seating for 5, 6, or 7 passengers (depending on config).
Falcon Wing Doors: Rear doors open upward in tight spaces; allow easy access to 3rd row.
100 kWh Battery: Large pack for its era.
Dual Motor AWD: Excellent traction in snow/mud (popular in Alpine regions).
Range (WLTP, 2018) : Approx. 500 km (310 miles) WLTP; real-world ~350–420 km depending on driving and weather.
Acceleration: 0–100 km/h in ~4.8 seconds (very quick for a 2.4-tonne SUV).
Air Suspension (Smart Air): Adaptive ride height; raises for off-road/rough roads, lowers for highway efficiency.
Towing Capacity: 2,250 kg (braked) – suitable for large caravans, horse trailers, or boat trailers (common in EU).
Cargo Space: ~2,500 litres with rear seats folded (far more than any Model 3).
2. Autopilot Benefits (2018 EU – Hardware 2.5 or 3?)
⚠️ Critical distinction: 2018 Model X originally shipped with HW2.5 (Hardware 2.5). Some received a free or paid upgrade to HW3 for FSD if originally purchased with FSD. Yours says Autopilot only (no FSD), so it likely still has HW2.5.
What you get with standard Autopilot (EU, 2018):
| Feature | Status | Notes |
|---|---|---|
| Traffic-Aware Cruise Control | ✅ Yes | Maintains speed and distance to car ahead |
| Autosteer (lane centering) | ✅ Yes | Works on highways and marked roads |
| Lane Departure Warning | ✅ Yes | Audible/visual alerts |
| Automatic Emergency Braking | ✅ Yes | Standard safety feature |
| Auto High Beams | ✅ Yes | |
| Auto Wipers | ✅ Yes | (Vision-based, sometimes unreliable) |
What you do NOT get (vs. FSD or later Autopilot):
❌ Navigate on Autopilot (auto lane changes, interchanges)
❌ Auto Lane Change (must disengage Autosteer, change lane manually, re-engage)
❌ Autopark (parallel/perpendicular parking)
❌ Summon / Smart Summon
❌ Traffic Light & Stop Sign Control
❌ City street Autosteer
Bottom line: This is basic highway Autopilot only – no lane changes, no parking aids. It’s comparable to a good adaptive cruise + lane keep system from 2018-era Mercedes/BMW.
3. Warranty Status (2018 EU Model – 2026 perspective)
Basic Vehicle Limited Warranty: 4 years / 80,000 km – Long expired (expired ~2022).
Battery & Drive Unit Warranty: 8 years / 240,000 km (150,000 miles) for the 100D.
If sold in late 2018, warranty expires late 2026 (or at 240k km).
If sold in early 2018, warranty already expired.
✅ Check your in-service date – you may have 0–6 months remaining as of mid-2026.
Corrosion Perforation Warranty: 12 years / unlimited km (still active until ~2030).
⚠️ High risk: Out-of-warranty Model X repairs are very expensive in the EU. Common issues: air suspension compressor, falcon wing door sensors, half-shafts (accelerated wear), MCU (eMMC failure).
4. Financial & Ownership Benefits (EU, 2026)
Advantages
Used Price Collapse – 2018 Model X 100D can be found for €35k–45k (vs. €100k+ new). Massive depreciation already taken.
Low Running Costs (vs. ICE SUV) – Electricity is cheaper than diesel/petrol for a vehicle this size.
Towing Tax Benefits – Some EU countries offer reduced road tax for EVs used to tow (e.g., France, Netherlands).
Supercharger Access – Full access to Tesla Supercharger network (though charging speeds are slower than newer cars).
Disadvantages / Costs to Consider
Out-of-warranty risk – Air suspension repair: €2k–4k. Falcon door mechanism: €1k–3k per door. MCU failure: €1.5k–2.5k.
MCU2 Upgrade Recommended – The original MCU1 (Intel Atom) is very slow, prone to eMMC failure. Tesla offers MCU2 upgrade for ~€2k–2.5k – worth it for responsive screen.
Charging Speed – Max ~150 kW (V2 Supercharger) or ~200 kW on V3 but throttled. 10–80% takes ~35–40 minutes (slower than Model 3).
Inefficient – Consumes ~220–250 Wh/km (vs. Model 3 ~150–170 Wh/km). Higher electricity cost per km.
Battery Degradation – 8-year-old battery likely at 85–90% original capacity.
5. Practical Benefits (Why buy this over a Model 3 Highland?)
| Use Case | 2018 Model X 100D | 2024 Model 3 Highland |
|---|---|---|
| Family with 3+ kids | ✅ Fits 6-7 people | ❌ Max 5 |
| Towing caravan/boat | ✅ 2,250 kg braked | ❌ 910 kg (or none) |
| Large dog / IKEA runs | ✅ Massive boot | ❌ Medium boot |
| Alpine ski trips | ✅ Air suspension + AWD | ⚠️ Good but less ground clearance |
| Daily commuting | ⚠️ High consumption | ✅ Very efficient |
| Falcon wing doors | ✅ Unique party trick | ❌ |
| Modern tech (screen, FSD) | ❌ Old MCU, basic Autopilot | ✅ Ryzen, FSD-capable |
6. Key Limitations (Be Honest About These)
| Issue | Severity | Mitigation |
|---|---|---|
| Out of basic warranty | 🔴 High | Purchase third-party EV warranty (e.g., CarGarantie in Germany) – expect €1k–2k/year |
| MCU failure risk | 🟡 Medium | Budget for MCU2 upgrade (~€2k) |
| Air suspension repair | 🟡 Medium | Get pre-purchase inspection (PPI) from Tesla-certified shop |
| Half-shaft vibration (accelerator shudder) | 🟡 Medium | Common on older X – check for vibration under hard acceleration |
| Falcon door sensor issues | 🟡 Medium | Test all door openings/closings multiple times |
| No FSD / no upgrade path | 🟢 Low (if not wanted) | Accept that this is a basic Autopilot car forever |
| Battery warranty expiring soon | 🔴 High (if no extension) | Check exact expiry date – if expired, battery replacement is €15k–20k |
7. Who Is This Car For? (EU Buyer Profile)
✅ Buy if:
You need 6-7 seats or massive cargo space.
You tow a caravan, horse trailer, or boat.
You understand the out-of-warranty risks and have a repair budget (or buy a third-party warranty).
You only want basic highway Autopilot (no interest in FSD or city driving).
You find a well-maintained example with documented service history (especially half-shafts, door mechanisms, MCU).
❌ Avoid if:
You want modern FSD features or even Auto Lane Change.
You can’t afford a potential €3k–5k repair in the first year.
You prioritize efficiency and modern interior (buy a 2022+ Model 3/Y instead).
You want a car under warranty – this is a cash-and-carry risk purchase.
Final Verdict
The 2018 Model X 100D with basic Autopilot is a high-risk, high-reward utility vehicle in 2026:
Reward: Unbeatable space, towing capacity, and falcon wing doors for €35k–45k.
Risk: Out-of-warranty repairs can quickly exceed the purchase price if major components fail.
Strongly recommend:
Get a pre-purchase inspection at a Tesla service center or specialist.
Check remaining battery/drivetrain warranty (if any).
Budget €2k–3k for MCU2 upgrade + potential minor repairs.
Consider a third-party extended warranty for high-risk components (air suspension, doors, battery).
