The Tesla Model 3 has rapidly become a benchmark in the electric vehicle (EV) market, known for its performance, technology, and evolving features. As Tesla continuously refines its vehicles, understanding the differences between model years is crucial for both prospective and current owners. This article delves into the specific changes and differences between the 2018 and 2020 Tesla Model 3, focusing on the Long Range All-Wheel Drive (LR AWD) and Standard Range Plus (SR+) models to provide a comprehensive guide for anyone interested in a Tesla Model 3 2018 or later.
Key Enhancements Across All 2020 Tesla Model 3 Trims
Tesla implemented several changes across all Model 3 trims from 2018 to 2020, enhancing safety, functionality, and user experience. These updates reflect Tesla’s commitment to continuous improvement and its responsiveness to customer feedback and evolving industry standards.
Safety and Auditory Updates
One notable addition to the 2020 models is the noise emitter. This feature, mandated for EVs traveling below 18 mph and in reverse, enhances pedestrian safety by providing an audible warning of the vehicle’s presence. This was a direct response to growing safety concerns regarding the near-silent operation of electric vehicles at low speeds.
Standard Driver Assistance Features
Another significant upgrade is the inclusion of Autopilot and Traffic-Aware Cruise Control as standard features in the 2020 Model 3. Previously, Autopilot was an optional upgrade. By making it standard, Tesla democratized access to these core driver-assistance technologies, which include automatic steering, acceleration, and braking within a lane under active driver supervision.
Interior and Practicality Improvements
Small but meaningful enhancements were also made to the interior and practicality of the Model 3. The plastic trim around the rear seat-back latch was slightly enlarged, providing a more refined finish. More significantly, the trunk was fully sealed off from the cabin in the 2020 models. Earlier 2018 and early 2019 models had an opening under the rear trunk deck, which was initially covered with fabric and later replaced with solid metal by July 2019. This change likely contributes to reduced cabin noise, particularly for rear passengers, and potentially improves climate control efficiency.
Exterior Design Tweaks
For added utility, a subtle but functional change was the addition of an under-bumper cutout for a trailer hitch. Introduced around June 2019, this feature, present even on the SR+ model, allows for easier installation of a trailer hitch for those needing to tow with their Model 3. Furthermore, a plastic rear license plate holder became standard, providing a cleaner and more secure mounting solution.
Model-Specific Changes: 2018 LR AWD vs. 2020 SR+
Beyond the changes applied across all trims, there are notable differences when comparing the 2018 Model 3 Long Range All-Wheel Drive to the 2020 Standard Range Plus. These differences largely stem from the variations in powertrain, battery capacity, and interior trim levels between these specific models.
Powertrain and Performance
The most fundamental difference lies in the powertrain configuration. The 2018 LR AWD features a dual-motor all-wheel-drive system, incorporating both front and rear motors. The front motor is an AC induction motor optimized for power, particularly at lower speeds, while the rear motor is a Permanent Magnet Switched Reluctance Motor (PMSRM) designed for efficiency and range. In contrast, the 2020 SR+ model is a rear-wheel-drive vehicle, equipped only with the rear PMSRM. The absence of the front motor in the SR+ directly impacts acceleration and all-weather traction compared to the LR AWD.
Battery Capacity and Range
Reflecting the “Long Range” designation, the 2018 LR AWD model boasts a larger 72kWh battery pack, providing a greater range compared to the 2020 SR+ with its 50kWh battery. This difference in battery capacity directly translates to a shorter range for the Standard Range Plus model, albeit with improved efficiency as highlighted by EPA ratings.
Interior Trim and Features
Stepping from the Premium Interior of the 2018 LR AWD to the Partial Premium Interior of the 2020 SR+ reveals some interior feature reductions. One noticeable change is the absence of ambient lighting LEDs in the door pockets of the SR+ model. This subtle lighting feature, present in the premium interior, enhances the cabin ambiance, especially at night.
Tire Pressure Recommendation
Interestingly, the recommended tire pressure also saw a slight increase from 42 psi to 45 psi between the 2018 LR AWD and 2020 SR+. This adjustment, indicated on the B-pillar sticker, could be attributed to various factors including tire design changes or optimization for efficiency and handling in the newer models.
Feature and Specification Deep Dive
To further illustrate the distinctions, let’s examine feature lists and specifications directly from Tesla and official sources.

EPA Efficiency Ratings
The US Department of Energy’s EPA Fuel Economy site provides standardized efficiency comparisons. The Tesla Model 3 Standard Range Plus has been recognized as one of the most efficient electric cars.
As the EPA data illustrates, the 2020 Tesla Model 3 Standard Range Plus achieves superior energy efficiency (MPGe) compared to the 2018 Long Range AWD model, despite having a smaller battery and range.
Decoding the VIN: Understanding Model Year and Specifications
Vehicle Identification Numbers (VINs) offer a standardized way to decode vehicle attributes and manufacturing details. Using VIN decoders, we can confirm specific details about each car.
Key VIN Digits and their Meanings for Model 3:
- Digits 1-3 (5YJ): Manufacturer – Tesla Inc.
- Digit 4 (3): Model – Tesla Model 3
- Digit 7 (E): Fuel Type – Electric
- Digit 8: Motor/Drive Unit (A= Single Motor Standard, B= Dual Motor Standard)
- Digit 10: Model Year (J = 2018, L = 2020)
- Digit 11 (F): Plant of Manufacture – Fremont, CA
By examining these digits, especially the 8th and 10th, one can quickly ascertain the motor configuration and model year of a Tesla Model 3.
Conclusion: Evolution of the Tesla Model 3
The Tesla Model 3 2018 and 2020 represent distinct stages in the vehicle’s ongoing evolution. The 2018 LR AWD prioritizes range and performance with its dual-motor setup and larger battery, while the 2020 SR+ emphasizes efficiency and affordability, incorporating standard safety and driver-assistance features across the board. For buyers considering a used Tesla Model 3 2018 or a newer model, understanding these differences is crucial in making an informed decision based on individual needs and priorities. Whether it’s the enhanced range and AWD capability of the 2018 model or the improved standard features and efficiency of the 2020 version, the Tesla Model 3 continues to offer a compelling package in the EV market.
