Tesla Model 3 Long Range AWD 2024 (Highland): The Dual-Motor Data Tesla Doesn't Publish

629 km WLTP. 341 miles EPA. 250 kW DC. 75 kWh usable. The Long Range AWD is the most popular trim in the Highland lineup — and it comes with a battery story that Tesla doesn't tell you at delivery. I spent time going through owner forum threads, charging session logs, and supplier identification data from multiple markets. Here's what actually matters once you start driving it every day.

The big thing to understand upfront: the LR AWD 2024 is not the same car everywhere. EU cars almost universally got LG NMC cells from Nanjing. US cars split between LG and Panasonic NCA depending on build window — and that difference affects the charging curve, long-term durability outlook, and even whether you qualified for the $7,500 tax credit. Same exterior, different pack, and Tesla tells you nothing about it at delivery.

1 Battery Pack — Two Suppliers, Two Different Stories EU · LG NMC · 78.8 kWh US · LG or Panasonic NCA · 78–82 kWh

Tesla publishes 75 kWh usable for the LR AWD across all markets. The gross figure depends entirely on which supplier built your cells. OBD logs and CoC documents from European owners consistently show 78.1–78.8 kWh gross for LG-equipped cars, with 75 kWh usable. Panasonic-cell cars — mostly US Fremont builds — start at 81–82 kWh gross, with the same 75 kWh usable. The buffer size differs, the pack size differs, the charge curve differs. The sticker says the same number.

One owner in Germany posted his CoC breakdown: LG 5L cells, 78.8 kWh gross, confirmed. His neighbour with a US-spec car from Fremont had a Panasonic BT42 designation — 81.5 kWh gross on his OBD read. Both cars show the same 75 kWh usable on the touchscreen. Neither shows cell supplier anywhere in the UI.

2 DC Charging — 250 kW Peak, and Why LG Cars Charge Differently EU · CCS2 · LG curve US · NACS · Panasonic curve

Both cells nominally support 250 kW DC. The difference is in how long they hold that peak. Panasonic cars hit 250 kW and stay close to it through 25–30% SoC before tapering. LG cars reach 250 kW briefly — somewhere around 10–20% — then step down faster. In practical road-trip terms, Panasonic packs add 50% charge in 13–17 minutes from 10%. LG packs take closer to 20–23 minutes for the same window. The gap isn't catastrophic, but it shows up on long days.

AC Charging — Same on Both Markets

On-board AC charger: 11 kW (3-phase, EU) / 11.5 kW (US NACS). Full 0–100% on an 11 kW wallbox takes roughly 8 hours. UK and EU owners on single-phase 7.4 kW: around 11.5 hours.

3 Real-World Range — What 629 km WLTP Looks Like on the Road EU · WLTP 629 km US · EPA 341 mi

629 km WLTP is the heavy-configuration TEH figure — 18" wheels, full passenger load. The light TEL figure reaches 678 km. Neither reflects motorway driving. An owner who just got his LR AWD in the UK and immediately did a Birmingham-to-Edinburgh run logged 418 km of real range at 110–120 km/h, with HVAC running. "About what I expected from research," he posted, "but still a kick in the gut when you first see the energy graph at 70 mph."

4 Battery Degradation — NMC Rules Apply, Not LFP EU · LG NMC US · Panasonic NCA

Calendar aging matters more than cycle count on both pack types. A UK owner with a 2024 LR AWD three months in mentioned he'd been charging to 100% most nights — someone in the forum corrected him immediately. "You have NMC, not LFP. Treat it differently." He switched to an 80% daily limit and set a target SoC average below 60%.

The degradation inflection point differs by chemistry: Panasonic NCA packs see meaningfully lower calendar aging below 55% average SoC. LG NMC packs have a slightly higher sweet spot — 60% average SoC halves calendar degradation on these cells. Practically, both benefit from the same rule: charge to 80% for daily use, charge to 100% only before long trips, and don't leave the car sitting at high SoC overnight regularly.

5 AWD in Practice — What the Second Motor Actually Costs You EU · 629 km WLTP US · 341 mi EPA

The front motor adds about 70 km (43 mi) of motorway range deficit versus the single-motor LR RWD — that gap is consistent across all owner data I've gone through. In city traffic it shrinks to almost nothing, because the front motor barely operates at low load. One owner who switched from an RWD to AWD posted his data from identical commute routes: city efficiency was within 4% between the two cars. At 120 km/h the AWD used about 8% more energy per kilometre.

What owners in Norway, Scotland, and Canada consistently say: the AWD is worth the range trade for anywhere that gets proper winter roads. "My RWD was fine 90% of the time. That other 10% was genuinely stressful," posted one Edinburgh owner who traded up. The AWD doesn't give you more grip on ice — no car does — but it controls slip between axles in a way that single-motor cars can't match on wet, leaf-covered, or lightly snowed surfaces.

6 What Owners Figured Out After Taking Delivery EU · Highland US · Highland

The Dashboard Shows EPA Range in All Markets

The touchscreen displays EPA-based range in all countries — including EU markets where WLTP is the advertised figure. At 100% charge a UK or German LR AWD shows roughly 492–510 km — not 629 km. This catches people immediately after delivery. It's not degradation. It's a different measurement standard, and Tesla doesn't explain it anywhere in the delivery process. Forum threads on this are hundreds of posts long.

No Turn Signal Stalks — 2024 Production

All 2024 Highland builds shipped without physical stalks. Tesla added them back in 2025 production. This comes up constantly in used-car threads — check the build date on the door card before buying. The steering wheel buttons work, but muscle memory for stalks is real, and a lot of owners mention it months into ownership.

Preconditioning Is Smarter Than You Think — But Only if You Use It

Navigate to a Supercharger and the car conditions the battery during the drive. Skip the navigation and drive straight there — no conditioning, slower ramp-up. In winter, that difference is 20–35 kW lower peak charging for the first 5–10 minutes. An owner who road-tripped across Germany in January: "First stop I forgot to navigate. Forty-five minutes to 80%. Second stop I used the nav. Twenty-nine minutes." Same car, same charger, one setting.

8" Rear Screen — Feature Nobody Uses, Heat It Generates

Standard on LR AWD both markets. Most adult owners mention they never touch it. A few mention seeing it affect front touchscreen responsiveness slightly during heavy streaming. Kids on long trips: game-changer. Adults commuting alone: background noise that happens to be a screen.

V2L — Still Not on Any Highland

No bidirectional charging of any kind on any trim. No V2L, no V2H, no V2G. No announced OTA path. It gets asked about in every LR AWD thread. The answer hasn't changed since Highland launched.
