When a legendary nameplate nears the end of its production run, automakers sometimes go out with a whimper. Tesla is going out with a 1,020-horsepower bang. The company confirmed it is producing 350 Final Signature Edition Model S and X Plaids — a combined 350 individually numbered units split between the sedan and the SUV — marking what is widely expected to be the last special run for both first-generation vehicles before Tesla shifts its Palo Alto and Fremont lines toward next-generation platforms.
If you are tracking this release, you already know these are not budget EVs. They are halo cars wrapped in exclusivity. But halo cars still need to make sense on paper: range, charging speed, ownership cost, and daily usability all matter — even at six figures. Here is everything we know about the Final Signature Edition Plaid models, with real numbers and real-world context.
What the Final Signature Edition Actually Is
The Final Signature Edition is a limited-production trim built on the existing Model S Plaid and Model X Plaid architecture. Tesla has not published a per-model split, but industry sources suggest approximately 175 units of each. Each vehicle receives a serialized dashboard badge, exclusive interior trim (new open-pore wood and Alcantara options), a unique "Signature" exterior badging package, and a bespoke wheel design not available on standard Plaid trims.
Mechanically, the Final Signature Edition carries over the tri-motor Plaid powertrain: one front motor and two rear motors with torque vectoring, producing a combined 1,020 horsepower and 1,050 lb-ft of torque. The battery pack remains Tesla's 100 kWh (usable) NMC (nickel-manganese-cobalt) architecture with structural improvements introduced in the 2023 refresh.
This is not a new generation. It is a farewell. And that distinction matters for buyers weighing whether to invest in a first-gen platform or wait for what comes next.
Range, Efficiency, and Real-World Expectations
The EPA-estimated range figures carry over from the standard Plaid trims, since the Final Signature Edition does not alter the battery or powertrain.
| Metric | Model S Plaid | Model X Plaid |
|---|---|---|
| EPA Est. Range | 396 miles | 333 miles |
| Usable Battery | ~100 kWh (NMC) | ~100 kWh (NMC) |
| MPGe (Combined) | 116 MPGe | 101 MPGe |
| kWh / 100 mi | 29 kWh | 33 kWh |
| Drivetrain | Tri-Motor AWD | Tri-Motor AWD |
Real-World Range Reality Check
Model S Plaid: EPA rates it at 396 miles, but expect roughly 320–340 miles on sustained highway driving at 70–80 mph. In cold weather (below 32°F), plan for 260–290 miles due to battery resistance and cabin heating load.
Model X Plaid: The 333-mile EPA figure drops to approximately 270–290 miles highway and 220–250 miles in freezing conditions. The X's larger frontal area and heavier curb weight (~5,185 lbs) compound efficiency losses at speed.
Tesla's heat pump helps mitigate cold-weather losses compared to resistive heating, but physics is physics — a 100 kWh pack moving 5,000+ pounds at highway speed in winter will consume more energy.
Charging Speed: DC Fast, Level 2, and the Curve
Charging speed is where the Plaid platform shows its age relative to 800V competitors like the Hyundai Ioniq 5 N or Porsche Taycan. The Model S and X Plaid operate on Tesla's 400V architecture, which limits peak DC fast-charge rates.
| Charging Level | Model S Plaid | Model X Plaid |
|---|---|---|
| Max DC Fast Charge | 250 kW (peak) | 250 kW (peak) |
| 10–80% DCFC Time | ~30 minutes | ~32 minutes |
| Sustained Rate (10–50%) | ~200–240 kW | ~190–230 kW |
| Level 2 (Home, 48A) | 11.5 kW (~41 mi/hr) | 11.5 kW (~35 mi/hr) |
| Level 1 (120V) | ~1.4 kW (~5 mi/hr) | ~1.4 kW (~4 mi/hr) |
| Connector | NACS (native) | NACS (native) |
The 250 kW peak is impressive on paper, but real-world charging follows a curve. You will see 250 kW only briefly in the 10–20% state-of-charge window. By 50%, the rate tapers to approximately 150 kW, and above 80% it drops sharply to protect battery longevity. For road trips, the practical strategy is charging from 10–80% in about 30 minutes and moving on — not sitting at the stall waiting for a full battery.
At home on a Level 2 Wall Connector (48 amps, 240V), you will add roughly 41 miles of range per hour in the Model S and 35 in the Model X. An overnight charge from 20% to 80% takes about 5–6 hours, which is perfectly adequate for daily use.
Performance: The 1,020-HP Case for Plaid
The tri-motor Plaid powertrain remains one of the quickest production car setups ever built. The Final Signature Edition carries identical performance hardware:
- 0–60 mph: 1.99 seconds (Model S), 2.5 seconds (Model X) — with rollout subtracted per Tesla's methodology
- Horsepower: 1,020 hp combined
- Torque: 1,050 lb-ft
- Top Speed: 200 mph (Model S), 163 mph (Model X)
- Quarter Mile: 9.23 seconds @ 155 mph (Model S)
The carbon-sleeve rotors in the rear motors allow them to spin at up to 20,000 RPM without disintegrating — an engineering detail that matters at the drag strip but is invisible in daily driving. What you will notice every day is the instant torque delivery, the torque-vectoring rear axle that pulls the car through corners, and the one-pedal regenerative braking that makes stop-and-go traffic effortless.
The adaptive air suspension provides a comfortable ride in its softest setting and firm body control when you dial it up. Ground clearance adjusts from approximately 4.6 inches (low/track) to 6.3 inches (high) in the Model S, and up to 8.2 inches in the Model X for rough roads or steep driveways.
Interior Space, Cargo, and Daily Livability
Despite their performance credentials, both vehicles are practical daily drivers — especially the Model X with its falcon-wing rear doors and optional six- or seven-seat configurations.
| Dimension | Model S Plaid | Model X Plaid |
|---|---|---|
| Front Legroom | 42.7 in | 41.2 in |
| Rear Legroom | 35.4 in | 37.1 in |
| Cargo (rear seats up) | 26.3 cu ft | 37.1 cu ft |
| Cargo (rear seats folded) | 64.9 cu ft | 81.5 cu ft |
| Frunk | 3.1 cu ft | 6.6 cu ft |
| Towing Capacity | N/A | 5,000 lbs |
The 17-inch landscape touchscreen remains the centerpiece of the interior, running Tesla's latest infotainment software with native streaming, gaming (the yoke-compatible gaming computer handles Cyberpunk 2077-level titles), and over-the-air updates. The yoke steering wheel is standard on Plaid trims — love it or hate it, it is non-negotiable at this level. A round wheel is not available on the Final Signature Edition.
The Model X's falcon-wing doors are a genuine advantage in tight parking spaces (they need only about 12 inches of side clearance) but add mechanical complexity and weight. They also limit roof-rack options.
Pricing, Tax Credit Eligibility, and What You Will Actually Pay
The Final Signature Edition commands a significant premium over the standard Plaid trims, reflecting its limited production and exclusive content.
| Trim | Base MSRP | As-Tested (est.) |
|---|---|---|
| Model S Plaid Final Signature | $129,990 | $134,990 (w/ FSD, red paint) |
| Model X Plaid Final Signature | $139,990 | $147,490 (w/ FSD, 6-seat, premium interior) |
Federal Tax Credit: The §30D Reality
Neither the Model S nor the Model X qualifies for the §30D federal EV tax credit. The IRS imposes an MSRP cap of $55,000 for sedans and $80,000 for SUVs/vans/pickups under current clean vehicle credit rules. At $129,990+ and $139,990+, both vehicles far exceed these thresholds. Additionally, buyer income caps ($300,000 joint / $150,000 single MAGI) and critical-mineral battery-sourcing requirements further restrict eligibility for vehicles near the cap.
Bottom line: budget the full MSRP. There is no federal incentive at this price point, and most state incentives also have MSRP caps well below six figures.
Warranty, Battery Longevity, and Ownership Costs
Tesla's warranty coverage for the Plaid powertrain is competitive with the luxury EV segment:
- Basic Vehicle Warranty: 4 years / 50,000 miles
- Battery & Drive Unit Warranty: 8 years / 150,000 miles, with a minimum 70% capacity retention threshold
- Roadside Assistance: 4 years / 50,000 miles
The NMC battery chemistry in the Plaid offers higher energy density than LFP (which Tesla uses in base RWD models), enabling the 396/333-mile range figures. However, NMC degrades slightly faster than LFP over time. Based on Tesla's own fleet data and third-party tracking, expect approximately 8–12% degradation over 100,000 miles with normal charging habits (keeping daily SoC between 20–80% and avoiding frequent 100% charges).
Insurance costs are a real consideration. Model S and X Plaids carry some of the highest EV insurance premiums in the market — expect $3,500–$5,500 annually depending on your state, driving record, and coverage level. Get quotes before ordering.
Tech, Driver Assistance, and the Autopilot Caveat
Every Final Signature Edition includes Tesla's Basic Autopilot (traffic-aware cruise control and autosteer). Full Self-Driving (Supervised) is a $8,000 add-on that enables automatic lane changes, navigation-guided on/off-ramp transitions, and traffic-light/stop-sign recognition.
SAE Automation Level: Level 2 — Not Self-Driving
Despite the "Full Self-Driving" name, Tesla's FSD (Supervised) is an SAE Level 2 driver-assistance system. The driver must remain fully attentive, keep hands on the yoke, and be prepared to take over instantly. This is not Level 4 autonomy (which describes driverless services like Waymo). Misuse of Level 2 systems has been linked to crashes investigated by NHTSA. Treat it as an advanced cruise control, not a chauffeur.
The infotainment system is best-in-class for responsiveness and app ecosystem, but the lack of Apple CarPlay and Android Auto remains a dealbreaker for some buyers at this price point. Tesla's native navigation, music streaming, and phone integration work well, but you are locked into Tesla's software ecosystem.
Final Signature Edition vs. Key Competitors
At $130,000–$150,000, the Final Signature Plaid models compete with a narrow field:
- Porsche Taycan Turbo GT: More engaging to drive, 800V architecture for faster charging (up to 320 kW), but lower range (~300 miles EPA) and no SUV variant.
- Lucid Air Sapphire: 1,234 hp, 427-mile EPA range, and a more luxurious interior — but limited service center network and no SUV equivalent.
- BMW iX M70: SUV competitor for the Model X, more traditional luxury feel, but only 619 hp and 307-mile range.
- Mercedes-AMG EQS SUV: Comfortable and well-appointed, but heavier, less efficient, and slower to charge.
The Final Signature Edition's unique value proposition is exclusivity (only 350 will exist), the Tesla Supercharger network (still the most reliable DC fast-charging ecosystem in the U.S., per fueleconomy.gov and owner surveys), and tri-motor performance that only the Lucid Sapphire exceeds on paper.

Who Should Buy the Final Signature Edition?
Choose the Model S Plaid Final Signature if: You want a sub-2-second sedan with 396 miles of range, plan to road-trip on Superchargers, and value numbered exclusivity over traditional luxury brand cachet.
Choose the Model X Plaid Final Signature if: You need a 5,000-lb-tow-capable electric SUV with three rows, want falcon-wing door practicality, and accept the efficiency penalty of a 5,185-lb vehicle.
Look elsewhere if: You want the newest platform (this architecture dates to 2012/2015 with refreshes), need Apple CarPlay, want 800V charging speeds, or are counting on federal tax credits to reduce the price.
Frequently Asked Questions
What is the real-world range of the Final Signature Edition Model S and X Plaid?
The Model S Plaid's 396-mile EPA rating translates to roughly 320–340 miles highway and 260–290 miles in freezing weather. The Model X Plaid's 333-mile EPA rating drops to about 270–290 miles highway and 220–250 miles in cold conditions. These are realistic figures for a 100 kWh NMC pack moving vehicles of this weight and power.
How fast do they charge at home and on the road?
On a DC fast charger (Supercharger V3 or equivalent), both vehicles peak at 250 kW and charge from 10–80% in approximately 30–32 minutes, though the sustained rate tapers significantly above 50% SoC. At home on a 48-amp Level 2 Wall Connector, expect 11.5 kW — adding about 41 miles per hour in the Model S and 35 miles per hour in the Model X.
Does the Final Signature Edition qualify for the federal EV tax credit?
No. Under IRS §30D rules, the MSRP cap is $55,000 for sedans and $80,000 for SUVs. At $129,990 (Model S) and $139,990 (Model X), both vehicles are well above the limit. Buyer income caps and battery-sourcing requirements further restrict eligibility. Budget the full sticker price.
Is the Final Signature Edition worth buying vs. the Lucid Air Sapphire or Porsche Taycan Turbo GT?
It depends on priorities. The Sapphire offers more power and range but has a sparse service network. The Taycan charges faster (800V) and drives more engagingly but has less range and no SUV variant. The Final Signature Edition's advantages are Supercharger network reliability, OTA software, and collectible exclusivity (350 units). If you value driving dynamics above all, drive the Taycan. If you value range and charging infrastructure, the Tesla wins.
What is the battery warranty and expected degradation?
Tesla covers the battery and drive unit for 8 years or 150,000 miles, guaranteeing a minimum 70% capacity retention. With the NMC chemistry, expect 8–12% degradation over 100,000 miles if you follow best practices (20–80% daily SoC, precondition for fast charging, avoid frequent 100% charges). A full battery replacement out of warranty would cost approximately $15,000–$20,000 based on current Tesla service pricing.
When will these 350 units be available?
Tesla has announced the production run of 350 combined units but has not published an exact delivery timeline. Allocation is expected to be managed through Tesla's existing reservation and direct-sales channels. Contact Tesla directly or monitor their official updates for ordering availability. As of this writing, units are listed as upcoming — not yet deliverable.
