Switching to an electric vehicle (EV) can be a significant leap, and for those considering the Tesla Model 3, understanding the evolution of this popular EV is crucial. As an early adopter of the Tesla Model 3 Standard Range Plus in Australia back in 2019, I recently had the opportunity to upgrade to the 2021 model. After driving over 10,000 kilometers in the new 2021 Tesla Model 3 Standard Range Plus, it’s time to share a detailed comparison highlighting the key differences and improvements, especially for those contemplating making the jump to electric mobility.
Tesla’s approach to vehicle updates is unique, opting for continuous improvement rather than traditional year-based model changes. This means a Tesla ordered today might have subtle differences compared to one produced just a few months prior. My experience moving from a 2019 US-built Model 3 to a 2021 Shanghai-manufactured version reveals several noteworthy enhancements. While my original 2019 Model 3 was already impressive, the 2021 iteration showcases a refined fit and finish, along with a series of upgrades that enhance the overall driving and ownership experience. Let’s delve into the specifics:
Enhanced Cabin Quietness with Double Pane Front Windows: Electric vehicles are inherently quiet, and Tesla has taken steps to further minimize noise intrusion in the 2021 Model 3. The introduction of double pane front windows significantly reduces external noise, creating an even more serene cabin environment. This refinement allows you to appreciate the subtle sounds within the car and enhances the overall sense of tranquility during your drive. Tesla, along with other EV manufacturers, also equips their vehicles with specialized acoustic tires, further contributing to noise reduction.
Redesigned Center Console for Modern Aesthetics and Functionality: The center console of the 2021 Tesla Model 3 has undergone a thoughtful refresh. The piano black finish, known for attracting fingerprints, has been replaced with a more sophisticated matte black finish throughout. This not only looks cleaner but also provides a more premium feel to the interior. Functionally, the updated console now includes a standard wireless phone charger and modern USB-C ports, replacing the USB-A outlets found in the 2019 model. These changes reflect Tesla’s commitment to continuous improvement and user-centric design.
Convenience of an Electric Liftgate: While seemingly a minor upgrade, the addition of an electric liftgate to the 2021 Model 3 enhances daily convenience. Unlike the manual liftgate in the 2019 model, the 2021 version allows for effortless opening and closing of the trunk with the touch of a button. This is a welcome refinement, particularly when your hands are full.
Securer Sentry Mode Storage in Glovebox: Tesla’s Sentry Mode, a valuable security feature, has been further enhanced in the 2021 Model 3. The Sentry Mode recording, which captures footage in case of potential break-ins or vandalism, has been relocated to the glovebox. This change, coupled with the addition of optional PIN access, provides a more secure storage location for the recorded footage. The included Tesla-branded 128GB USB drive in the glovebox ensures that any captured evidence is safely stored, even if the car is compromised.
Matrix LED Headlights for Superior Illumination: The headlights on the 2021 Tesla Model 3 have been upgraded to the latest Matrix LED style, a feature commonly found in high-end vehicles. These new headlights offer significantly improved illumination compared to the 2019 model. The enhanced lighting performance provides better visibility at night and in adverse weather conditions, contributing to safer driving. The difference in headlight technology is a noticeable upgrade, enhancing both safety and aesthetics.
Heat Pump for Increased Energy Efficiency: Tesla’s focus on maximizing EV range is evident in the integration of a heat pump in the 2021 Model 3. The heat pump is an engineering advancement designed to improve energy efficiency, particularly in colder climates. While the 2019 Model 3 SR+ averaged around 134 Wh/km, my 2021 model is currently averaging 125 Wh/km, representing approximately a 7% improvement in energy consumption. This efficiency gain is especially notable as a significant portion of my driving in the 2021 model has been during winter months, when EVs typically experience reduced range. The heat pump is a key contributor to this improved efficiency. The image above illustrates the more complex heat pump system in the 2021 model (right) compared to the 2019 model (left).
Refined Acceleration Feel: While subjective without dyno testing, the 2021 Tesla Model 3 Standard Range Plus appears to offer a smoother acceleration experience from 0 to 100 km/h. In the 2019 model, the acceleration felt like it had two stages, with a noticeable surge of power after the initial launch. The 2021 version delivers a more linear and consistent power delivery throughout the acceleration range. This smoother acceleration could be attributed to factors such as the larger battery pack, different battery chemistry, or refined software mapping, all contributing to a more refined driving dynamic.
Enhanced Charging Characteristics: Charging speeds have also seen improvements in the 2021 Model 3. While the peak supercharging rate may be similar to later software updates for the 2019 model, the 2021 Model 3, equipped with a different battery chemistry, exhibits a flatter charging curve. This means the charging speed remains more consistent for a longer portion of the charging process, particularly as the battery approaches full capacity. This more consistent charging curve is beneficial for mass EV adoption, as it simplifies the explanation of EV charging behavior, which traditionally slows down as the battery fills up.
Game-Changing LFP Battery Chemistry: Perhaps the most significant change in the 2021 Tesla Model 3 Standard Range Plus is the introduction of a Lithium Iron Phosphate (LFP) battery. This differs from the Lithium-Nickel-Cobalt-Aluminum (NCA) battery in my 2019 model. While NCA batteries, typically supplied by Panasonic and LG Chem, are more energy-dense and lighter, LFP batteries offer advantages in safety, longevity, and charging habits. LFP batteries, sourced from CATL for Tesla, are more thermally stable, have a longer cycle life, and can be charged to 100% without significant degradation concerns, unlike NCA batteries which are typically recommended to be charged to 80-90% for daily use.
The real-world implications of the LFP battery are substantial:
- Increased Daily Range: The 2021 Model 3 with LFP battery provides a higher indicated range at 100% charge, showing 423 km compared to approximately 380 km in my 2019 NCA-equipped model.
- Simplified Charging Management: Concerns about optimal charging practices are minimized with LFP batteries. Charging to 100% is not detrimental, removing the need to constantly adjust charging limits for daily use versus long trips.
- Robust Battery Longevity: After 10,000 km, the LFP battery in my 2021 Model 3 shows no noticeable degradation and consistently displays the original 423 km range at full charge.
Furthermore, the 2021 Model 3 with LFP battery appears to have improved regenerative braking management. In the 2019 model, regenerative braking was limited when the battery was charged to 100%, affecting the driving feel. The LFP-equipped 2021 Model 3 provides consistent regenerative braking performance regardless of the charge level, contributing to a more predictable and enjoyable driving experience.
These improvements, particularly the LFP battery, are pivotal for broader EV adoption. The robustness and simplified charging management of the LFP battery align perfectly with the needs of the mass market. As Tesla demonstrates by removing the “daily” vs “trip” charging limit display (pictured above, NCA on the left, LFP on the right), the focus is shifting towards a more straightforward and user-friendly EV ownership experience.
The 2021 Tesla Model 3 Standard Range Plus represents a significant step forward in EV technology and user-friendliness, making it an even more compelling option for those looking to transition to electric driving.
