Tesla 2018 Model 3 vs 2020: Unpacking the Evolution of the Game-Changing EV

The Tesla Model 3 burst onto the scene in 2017, quickly becoming the most sought-after electric vehicle (EV) in the market. For those considering a pre-owned Tesla, the 2018 Model 3 represents a pivotal early production year. However, Tesla is known for its rapid innovation and iterative design improvements. By 2020, the Model 3 had undergone numerous changes, both subtle and significant.

This in-depth comparison, crafted by a fellow Tesla Model 3 owner, dives into the key differences between the 2018 and 2020 Tesla Model 3. We’ll explore changes implemented across all Model 3 trims and specifically highlight the distinctions between the 2018 Long Range All-Wheel Drive (LR AWD) and the 2020 Standard Range Plus (SR+) models. Whether you’re weighing a used 2018 Tesla Model 3 against a newer model or simply curious about the evolution of this groundbreaking car, this guide will provide the insights you need.

Key Updates Across All Tesla Model 3 Trims (2018 to 2020)

Tesla continuously refines its vehicles, and the Model 3 is no exception. Between 2018 and 2020, several updates were implemented across the entire Model 3 lineup, enhancing safety, functionality, and user experience.

Subtracted or Streamlined Features

While Tesla added many features, some elements were removed or simplified in the 2020 models. These changes often reflect cost optimization or design streamlining.

Refined and Modified Elements

Several aspects of the Tesla Model 3 were refined or modified between 2018 and 2020, demonstrating Tesla’s commitment to continuous improvement.

Added and Enhanced Features

The 2020 Tesla Model 3 gained several new features and enhancements compared to the 2018 model, reflecting advancements in technology and responses to customer feedback.

Pedestrian Safety Enhancement: Noise Emitter. In line with evolving safety regulations, 2020 Model 3s and later models are equipped with a noise emitter. This system produces sound at low speeds (below 18 mph and in reverse) to alert pedestrians to the vehicle’s presence, a crucial safety feature for EVs which are inherently quieter than gasoline cars.
Standard Autopilot Features. A significant upgrade for the 2020 Model 3 was the inclusion of Tesla’s Autopilot as a standard feature. This system provides Traffic-Aware Cruise Control and Autosteer, assisting with steering, acceleration, and braking within a lane. It’s important to note that Autopilot requires active driver supervision and is not full self-driving capability.
Traffic-Aware Cruise Control (Standard). As mentioned above, Traffic-Aware Cruise Control became standard with Autopilot in the 2020 Model 3. This feature automatically adjusts the car’s speed to maintain a safe following distance from vehicles ahead, enhancing safety and convenience in highway driving and stop-and-go traffic.
Enhanced Rear Seat-Back Latch Trim. A minor but noticeable change is the slightly larger plastic trim around the rear seat-back latch (the 1/3 split). This provides a more finished look in the trunk area.
Sealed Trunk from Cabin. One of the more practical improvements is the trunk’s complete sealing from the cabin. Early 2018 Model 3s had a large opening under the rear deck. This was initially covered with a fabric-like material in early 2019 and finally became solid metal by mid-2019. This change likely contributes to reduced cabin noise, especially for rear passengers.

Trailer Hitch Ready Bumper. Starting around June 2019, Model 3s gained a subtle cut-out under the rear bumper to accommodate a trailer hitch. This applies even to the Standard Range Plus models, increasing the car’s utility for owners who need to tow light loads.
Standard Rear License Plate Holder. A minor but welcome addition is the inclusion of a plastic rear license plate holder as standard equipment.

Model-Specific Changes: 2018 LR AWD vs. 2020 SR+ Tesla Model 3

Moving beyond changes across the board, significant differences exist when comparing specific Tesla Model 3 configurations from 2018 and 2020. Our focus here is on the 2018 Long Range All-Wheel Drive (LR AWD), representing the premium end of the early Model 3 spectrum, and the 2020 Standard Range Plus (SR+), a more affordable, efficiency-focused variant. These differences extend beyond just range and price, impacting features and performance. Notably, the SR+ steps down from the Premium Interior found in the LR AWD to a Partial Premium Interior.

Features Removed or Reduced in the 2020 SR+

Choosing the Standard Range Plus in 2020 meant forgoing some of the premium features present in the 2018 Long Range AWD. These reductions helped achieve a lower price point while still delivering core Tesla performance and technology.

Front Motor (Dual Motor vs. Single Motor). The most fundamental difference is the drivetrain. The 2018 LR AWD boasts a dual-motor all-wheel-drive system, featuring an additional front motor optimized for power at low RPM. This motor, an AC induction type, is absent in the 2020 SR+, which utilizes a single-motor rear-wheel-drive configuration. All Model 3s, including the SR+, retain a rear Permanent Magnet Switched Reluctance Motor (PMSRM), known for its efficiency and range optimization. The removal of the front motor in the SR+ contributes to its increased efficiency and lower cost.
Battery Capacity Reduction. To achieve the “Standard Range,” the 2020 SR+ features a smaller battery pack compared to the 2018 LR AWD. The LR AWD is equipped with a 72kWh battery, while the SR+ has a 50kWh battery. This reduced battery capacity directly impacts the range and also contributes to the lower weight and potentially improved handling of the SR+.

Features Added or Increased in the 2020 SR+

Despite some feature reductions, the 2020 Standard Range Plus also gained some enhancements compared to the 2018 LR AWD, often focused on efficiency and optimization.

Increased Tire Pressure. The recommended tire pressure was raised from 42 psi to 45 psi in the 2020 SR+. This seemingly minor change can contribute to improved rolling resistance, thereby increasing efficiency and range. The correct tire pressure is indicated on a sticker located on the B-pillar, behind the front driver-side door.

Features That Remained Consistent

Despite the changes, certain aspects remained consistent between the 2018 LR AWD and 2020 SR+, ensuring a core Tesla experience across models.

The original article mentions “Same” section with cryptic information about “Caraoke and Music Streaming” potentially only working on WiFi for SR+. This seems to be clarified later in the original text to be incorrect based on testing, and all streaming services worked fine on cellular. Therefore, this point is not relevant as a “same” feature and is omitted for clarity in this rewritten article.

Visual Deep Dive: Video Comparisons

For a more dynamic and visual comparison, video content can be incredibly helpful. The original article references a video comparing the two models. While the initial video had some audio and production limitations, a much-improved video was later released.
