Porsche 911 Electric Conversion: Costs, Performance and Experiences (2026)
The Porsche 911 is one of the most sought-after classics worldwide — and is increasingly being converted to electric. According to IEA (2024) global EV registrations grew by 35% year-on-year, and with them the interest in electric conversions for classic sports cars. An electric 911 combines the timeless silhouette with a modern drivetrain: up to 450 kW of power, 300 km of range and torque from the very first revolution. No wonder Porsche owners are seriously considering this option.
This guide shows you all available variants — from the entry-level PURE kit at €44,990 to the ULTIMATE package with Tesla LDU and over 550 hp. You will learn what the conversion really costs, how TÜV and registration work, and what it means for your H-plate. If you are just starting out, we recommend our complete guide to electric car conversion.
TL;DR: A Porsche 911 electric conversion starts at €44,990 (PURE, 132 kW) and goes up to the ULTIMATE package with Tesla LDU and 450 kW. The Porsche 964 is available from €59,990 as the PERFORMANCE variant. All kits offer CCS fast charging (up to 90 kW), 250–350 km of range and are prepared for the TÜV individual approval. Modern Tesla permanent-magnet motors work very efficiently at their optimal operating point.
Why convert a Porsche 911 to electric?
Demand for classic-car electric conversions is growing rapidly. According to Classic Analytics (2025) non-drivable combustion classics lose 3–5% of their value annually — an electrically drivable 911, by contrast, holds its value steady or even rises. The electric conversion is not a betrayal of the original, but an investment in the future of your Porsche.
Preserve the classic instead of retiring it
More and more cities in Europe are tightening their low-emission zones. A 911 with a combustion engine may only drive in Paris, London or Amsterdam to a limited extent. With an E-license plate you are exempt from driving bans — and your Porsche stays usable in everyday life instead of gathering dust in the garage. Anyone who loves their 911, after all, wants to drive it.
Modern performance in a classic guise
An original Porsche 911 G-model with the 3.2-litre boxer produces around 170 kW (231 hp). The PERFORMANCE kit delivers 220 kW (300 hp), the ULTIMATE package even 450 kW (over 550 hp). The torque is available instantly — no revving up, no turbo lag. At the traffic lights an electric 911 leaves most modern sports cars behind.
Sustainability without compromise
According to, producing a new electric vehicle causes Transport & Environment 8–12 tonnes of CO2. When converting an existing 911, this item is eliminated entirely. You keep using the existing body and give it a second life. That is circular economy in practice — not just marketing.
Which Porsche models are suitable for electric conversion?
In principle, all air-cooled Porsche models are suitable for electric conversion. Tesla drives are among the most frequently used drives for professional EV conversions — and the compact design fits particularly well into the rear-engine layout of the classic Porsche architecture.
Porsche 911 G-model (1974–1989)
The G-model is the classic among conversion candidates. No complex electronics, a manageable wiring harness and a rear-engine layout that is ideally suited for installing a Tesla Drive Unit. The simple chassis makes it easier to house the battery in the front end (former luggage compartment) and in the central tunnel. Three kit levels are available: PURE, PERFORMANCE and ULTIMATE.
Porsche 964 (1989–1994)
The 964 brings more kerb weight than the G-model, but also has a wider underbody and more room for battery modules. The stiffer chassis copes better with the extra mass. PERFORMANCE and ULTIMATE are available as dedicated 964 kits — with an adapted adapter plate and optimised weight distribution.
Porsche 912 and 914
The 912 (four-cylinder 911) and the mid-engine 914 can also be electrified. Both are lighter than the 911 and therefore benefit from more range per kilowatt-hour. However, unit numbers are smaller and tailor-made kits less common. For the 912, the 911 kit can be adapted in many cases.
Which variants are there? PURE, PERFORMANCE and ULTIMATE compared
For the Porsche 911 there are three graduated conversion kits. The price range runs from €44,990 (PURE) to the ULTIMATE package on request. Tesla permanent-magnet motors work very efficiently — this efficiency directly benefits the range of your 911.
| Property | PURE (€44,990) | PERFORMANCE (€54,990) | ULTIMATE (on request) |
|---|---|---|---|
| Drive | Tesla Drive Unit | Tesla Drive Unit | Tesla LDU |
| Power | 132 kW / 180 hp | 220 kW / 300 hp | 450 kW / 550+ hp |
| Battery | 40 kWh | 45 kWh | 48 kWh |
| Range | up to 250 km | up to 300 km | up to 300 km |
| AC charging | 10 kW | 10 kW | 10 kW |
| DC charging (CCS) | — | 70 kW | 90 kW |
| Price | 44.990 € | 54.990 € | on request |
PURE: the entry point for weekend pilots
The PURE kit from €44,990 delivers 132 kW (180 hp) and 40 kWh of battery capacity. With it you reach up to 250 km of range — enough for outings, meet-ups and the Sunday trip along country roads. Charging is via a 10 kW AC connection. A wallbox charge takes around four hours. CCS fast charging is not included in this variant.
For whom? Porsche owners who use their 911 as a leisure vehicle and are looking for a clean, affordable entry into the electric conversion.
PERFORMANCE: the all-rounder for everyday use
With 220 kW (300 hp), a 45 kWh battery and CCS fast charging up to 70 kW, the PERFORMANCE variant at €54,990 is the complete package. 300 km of range also covers longer day trips. At a CCS fast charger you reach 10 to 80% in around 25 minutes. This makes the 911 long-distance capable.
For whom? Anyone who wants to use their 911 as a daily vehicle or regular touring car — without compromises on performance and charging comfort.
ULTIMATE: the no-compromise solution
The ULTIMATE package with Tesla Large Drive Unit delivers a brutal 450 kW (over 550 hp) and a 48 kWh battery. CCS charging up to 90 kW ensures fast top-ups on the road. Range is up to 300 km. The price? On request — this kit is aimed at enthusiasts who want the maximum.
Tesla LDU in the Porsche 911: the ULTIMATE package in detail
The Tesla Large Drive Unit (LDU) is the powerhouse among the Tesla drives. With up to 450 kW and over 600 Nm of torque it catapults the 911 into a performance class that even a Porsche 911 Turbo S (478 kW) only just surpasses. In Tesla-based conversions, above all these three main drive types are used: SDU, LDU and Model 3 DU.
Why the LDU for the 911?
The 911 is a sports car — and deserves a sports-car drive. The LDU originally comes from the Tesla Model S P100D, one of the fastest production vehicles in the world. In the 911 ULTIMATE it delivers acceleration figures under 4 seconds from 0 to 100 km/h. After the conversion, the weight of the Porsche is well below that of a Model S, which further benefits the driving performance.
You will find a detailed comparison of all Tesla drive units — SDU, LDU and Model 3 DU — in our Tesla motor comparison for classic cars.
Power and driving feel
450 kW in a vehicle weighing under 1,400 kg — that is another world. The instantly available torque fundamentally changes the character of the 911. No waiting for the revs, no shifting, no turbo lag. Instead, linear, brutally fast propulsion. The sound? Whisper-quiet. Some miss the boxer growl. But once you have experienced the acceleration, you soon forget it.
Thermal management and battery
The 48 kWh battery in the ULTIMATE package is equipped with an active cooling system. That is essential at 450 kW power draw — without thermal management the cells would overheat during repeated full-throttle bursts. CCS fast charging up to 90 kW means: from 10 to 80% in 20 minutes. For track days or Alpine tours, a decisive advantage.
Porsche 964 electric conversion: PERFORMANCE and ULTIMATE
The Porsche 964 gets its own dedicated conversion kits. The PERFORMANCE variant starts at €59,990 and delivers 220 kW (300 hp) with a 45 kWh battery capacity and up to 300 km of range. According to Classic Analytics (2025) the 964 is among the most value-stable Porsche classics — a reversible electric conversion protects this value.
| Property | 964 PERFORMANCE (€59,990) | 964 ULTIMATE (on request) |
|---|---|---|
| Drive | Tesla Drive Unit | Tesla LDU |
| Power | 220 kW / 300 hp | 400 kW / 550 hp |
| Battery | 45 kWh | 48 kWh |
| Range | up to 300 km | up to 350 km |
| DC charging (CCS) | 70 kW | 90 kW |
| Price | 59.990 € | on request |
Why is the 964 more expensive than the 911 G-model?
The 964 has a more complex chassis, power steering, ABS and more electronics than the G-model. Integrating the electric kit therefore requires additional adaptation work. The adapter plate is tailored specifically to the 964 chassis. In addition, the 964 benefits from a stiffer structure that better compensates for the extra weight of the battery.
964 ULTIMATE: 400 kW and 350 km range
The ULTIMATE package for the 964 delivers 400 kW (550 hp) with Tesla LDU and the largest battery in the portfolio: 48 kWh for up to 350 km of range. CCS fast charging at 90 kW makes longer tours comfortable too. The wider underbody of the 964 offers more room for the battery modules — that explains the 50 km of extra range compared with the 911 ULTIMATE.
What does the complete Porsche 911 electric conversion cost?
The pure kit prices range from €44,990 (911 PURE) to €59,990 (964 PERFORMANCE). But the total price of a conversion is higher. According to emobility.energy (2025) for electric conversions, 40–60% of the total cost is attributable to the battery — with the Porsche kit this is already included in the price. Nevertheless, additional costs apply.
You will find a complete overview of all cost items for electric conversions in our cost guide.
Additional costs beyond the kit price
| Cost item | Price range | Note |
|---|---|---|
| Conversion kit (911) | 44.990–54.990 € | PURE or PERFORMANCE |
| Conversion kit (964) | €59,990 / on request | PERFORMANCE or ULTIMATE |
| TÜV individual approval | 500–2.000 € | Depending on inspection body and scope |
| Installation (specialist workshop) | 3.000–8.000 € | Depending on workshop and region |
| Bodywork / preparation | 1.000–5.000 € | Rust, adjustments, paintwork |
| Heating (electric) | 500–1.500 € | The boxer engine no longer provides warmth |
| Registration and re-registration | 100–300 € | Apply for E-license plate |
In total you should reckon on €60,000 to €70,000 for a complete 911 PERFORMANCE project. With the PURE kit you end up at €50,000 to €60,000 in total costs. The 964 PERFORMANCE comes to €65,000 to €75,000 including all additional costs. Sounds like a lot? For comparison: a turnkey electric Porsche 911 from specialist providers quickly costs over €200,000.
Does the conversion pay off financially?
Short-term? No — it is not a money-saving model. Long-term the maths looks better. According to ADAC/Bundestag (December 2025) electric vehicles are exempt from vehicle tax until 2035. On top of that come lower operating costs: no oil changes, less brake wear thanks to recuperation, cheaper electricity instead of Super Plus. And the increase in value? A drivable, electrified Porsche classic will probably be worth significantly more in ten years than one that can no longer be moved because of driving bans.
How does the TÜV individual approval work for the Porsche?
Every electric conversion in Germany requires a TÜV individual approval under §19 and §21 StVZO. According to TÜV/DEKRA the cost of the approval alone is between 500 and 2,000 euros. Vehicles first registered after 17 June 2003 additionally require an EMC test for 5,000–8,000 euros (AutoZeitung).
We explain all the details of the process in our step-by-step guide to the TÜV individual approval.
Good news for most Porsche classics
The G-model (until 1989) and the 964 (until 1994) were both first registered before the 17 June 2003 cut-off date. That means: the expensive EMC test is usually omitted, provided all installed components carry a CE marking. With TÜV-compliant kits this is the case as standard. This potentially saves you 5,000 to 8,000 euros.
What does the inspector pay particular attention to?
With the Porsche 911 there are specific points that the TÜV inspector examines closely. The battery housing in the front end must be crash-safe — the 911 has its luggage compartment at the front, not an engine block as a crumple zone. The axle-load distribution is also checked: if the weight shifts too far forward, the typical rear-engine handling suffers. Clean documentation of all components, wiring diagrams and strength certificates is mandatory.
Checklist for the Porsche approval
- Technical description of the complete conversion
- High-voltage wiring diagrams and low-voltage wiring
- Strength certificates for motor mounts and battery mounting
- Safety data sheets for the battery cells
- CE declarations of conformity for all electrical components
- Weighing protocol with individual axle loads
- Proof of contact protection for all HV components
- BMS function proof (overcharge, deep discharge, short circuit)
H-plate vs. E-plate: what happens after the conversion?
The electric conversion means the loss of the H-plate. According to AutoServicePraxis the classic-car plate is tied to the largely original condition — a new drivetrain contradicts this principle. Instead you get an E-license plate with its own advantages. All the details in our guide to the E-license plate after conversion.
What you lose
With the H-plate the flat-rate vehicle tax of €191.73 per year is eliminated. In addition, the cheap classic-car insurance tariffs are lost. For many 911 owners that is an emotional point — the H-plate has symbolic value. However: a reversible conversion keeps the return to the original engine open. If the boxer is stored properly, the 911 remains theoretically H-plate-eligible again.
What you gain
| Aspect | H-plate | E-license plate |
|---|---|---|
| Vehicle tax | Flat rate €191.73/year | €0 until 2035 |
| Low-emission zones | Exempt | Exempt |
| Driving bans (EU-wide) | Not protected | Fully exempt |
| Parking | Normal | Free in many cities |
| Requirement | Largely original condition | Purely electric drive |
| Insurance | Cheap classic-car tariffs | Standard tariffs |
In tax terms you are better off with the E-plate: zero euros instead of €191.73 per year. But the truly decisive point is future-proofing. More and more European cities are banning combustion engines from their inner cities. Your electric 911 is allowed everywhere — now and in 20 years.
Frequently asked questions about the Porsche 911 electric conversion
What does a Porsche 911 electric conversion cost?
Kit prices start at €44,990 (PURE, 132 kW) and go up to €54,990 (PERFORMANCE, 220 kW). The ULTIMATE package with Tesla LDU and 450 kW is available on request. Including installation, TÜV individual approval and additional costs, for the 911 PERFORMANCE you should reckon with €60,000 to €70,000 in total costs. The cost guide breaks down all the items.
How much range does an electric Porsche 911 have?
Between 250 and 300 km, depending on the variant. The PURE kit offers 250 km with 40 kWh, PERFORMANCE and ULTIMATE reach 300 km with 45 and 48 kWh respectively. The average German daily mileage is 39 km (Federal Statistical Office) — even the smallest variant covers that six times over. In winter, range drops by 15–30% due to heating demand.
Will I lose my H-plate with the Porsche conversion?
Yes. The H-plate requires a largely original condition. An electric drivetrain contradicts that. Instead you apply for an E-license plate with vehicle-tax exemption until 2035 (ADAC/Bundestag, December 2025). A reversible conversion keeps the later return to the H-plate open.
Can I reverse the Porsche 911 electric conversion?
Yes — the kits are designed to be reversible. The original engine can be stored and reinstalled later without irreversible changes to the bodywork being necessary. That is decisive for collector value. If the boxer engine is supplied and documented, the 911 remains flexible in the long term.
Do I need an EMC test for my 911?
In most cases, no. The EMC test (€5,000–8,000) is only mandatory for vehicles first registered after 17 June 2003. Porsche 911 G-models and 964s were registered significantly earlier and are usually exempt — provided all components carry a CE marking. For details, see our TÜV guide.
Conclusion: the 911 goes electric — and stays a Porsche
A Porsche 911 electric conversion is not a compromise but an upgrade. From 132 kW in the PURE kit to 450 kW with Tesla LDU in the ULTIMATE — the performance range covers everything, from the relaxed Sunday driver to the track-day enthusiast. With 250 to 350 km of range and CCS fast charging up to 90 kW, long-distance capability is also assured.
Three things are decisive. First: choose the variant that fits your driving profile. Not everyone needs 450 kW. Second: plan the total cost realistically — kit price plus installation, TÜV and additional costs. Third: a reversible conversion protects the collector value and keeps all options open.
