For those considering making the switch to electric vehicles (EVs), the Tesla Model 3 Standard Range Plus has long been a compelling option. As an early adopter of the Model 3 in Australia, I had the privilege of experiencing both the 2019 and the updated 2021 versions. After putting over 10,000 kilometers on my 2021 Tesla, I’m excited to share a detailed comparison highlighting the significant improvements and changes that make the newer model an even more attractive choice.
Tesla’s production evolution is unique; instead of annual model year updates like traditional automakers, they implement continuous improvements. This means a 2021 Tesla ordered even a few months apart might have subtle differences. The most notable shift for the Australian market was the transition from US-built models to those manufactured in Tesla’s Shanghai factory. This change initially affected the Standard Range Plus and subsequently extended to the Long Range and Performance models. Accompanying this production shift was a series of “refresh” enhancements, resulting in a demonstrably improved vehicle overall. While my 2019 Model 3 was already impressive, the 2021 Tesla exhibits enhanced fit and finish, subtle yet noticeable upgrades that elevate the ownership experience. Let’s delve into the specifics of these refinements.
Enhanced Quietness and Interior Comfort
Double Pane Front Windows: One of the first things you’ll appreciate in the 2021 Tesla is the significantly reduced cabin noise thanks to the introduction of double-pane front windows. EVs are inherently quiet, making any noise reduction efforts even more impactful. These windows effectively dampen external sounds, allowing you to enjoy the serene driving experience and appreciate nuances you might have missed before. Tesla, and other EV manufacturers, also utilize specialized acoustic tires to further minimize road noise, contributing to a remarkably peaceful ride.
Refreshed Center Console: The interior receives a welcome upgrade with a redesigned center console. While the previous design was functional, the 2021 Tesla boasts a more refined aesthetic. The fingerprint-prone piano black finish is replaced with a sophisticated matte black, providing a cleaner and more premium feel. Functionality is also enhanced with the inclusion of a standard wireless phone charger and modern USB-C ports, replacing the older USB-A outlets. This modern touch elevates the convenience and usability of the center console area.
Electric Boot (Trunk): While certainly a luxury, the addition of an electric boot is a convenient upgrade. The 2021 Tesla Model 3 eliminates the need to manually close the trunk, a small but appreciated improvement, especially when your hands are full.
Security and Lighting Enhancements
Glovebox Sentry Mode Storage: Tesla’s Sentry Mode, a valuable security feature that records surroundings when the car is parked, sees a practical improvement in the 2021 model. The storage location for Sentry Mode recordings has been relocated to the glovebox, offering enhanced security. Pin number access can also be enabled for the glovebox, ensuring that in the event of a break-in, the recorded footage remains protected on the included Tesla-branded 128GB USB drive.
Matrix Headlights: 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. The improvement in lighting performance is substantial. The Matrix headlights offer superior illumination and intelligent beam control, adapting to driving conditions and enhancing visibility, making nighttime driving significantly safer and more comfortable. The difference compared to the 2019 headlights is truly remarkable.
Efficiency and Performance Improvements
Heat Pump for Enhanced Efficiency: Tesla’s relentless focus on maximizing EV range is evident in the 2021 Model 3’s inclusion of a heat pump. This engineering marvel significantly improves energy efficiency, particularly in colder climates. Software enhancements also contribute, such as optimizing climate control by reducing AC usage in unoccupied sections of the cabin. In my experience, the 2021 Tesla demonstrates a notable improvement in energy consumption, averaging 125Wh/km compared to 134Wh/km in my 2019 model – a roughly 7% gain. This improvement is even more impressive considering a significant portion of my driving in the 2021 model was during winter, a less favorable condition for EV efficiency. The heat pump is a key contributor to this enhanced efficiency.
Smoother Acceleration: While requiring precise dyno testing for definitive confirmation, my subjective experience suggests smoother acceleration in the 2021 Tesla Model 3 Standard Range Plus. The 2019 model felt like it had a slight initial lag before accelerating more assertively, whereas the 2021 Tesla delivers a more linear and consistent power delivery from 0 to 100 km/h. This smoother acceleration might be attributed to the larger, heavier battery pack and refined software mapping, even while maintaining the same 0-100 km/h time.
Improved Charging Curve: Charging speeds have also seen refinement. While the 2019 Model 3 received software updates boosting supercharging speeds, the 2021 Tesla with its new battery chemistry exhibits a more desirable charging curve. The peak charge rate remains rapid, but importantly, the taper rate as the battery fills is significantly flatter. This is a crucial improvement for mass EV adoption, as it addresses the common misconception that EV charging remains consistently fast throughout the process. A flatter charging curve means more consistent and predictable charging times, especially in the higher state of charge range. For a detailed analysis, resources like the MIC Tesla Model 3 SR+ Fast Charging Test provide in-depth insights.
Battery Technology: LFP Revolution
Lithium Iron Phosphate (LFP) Battery: The most significant change in the 2021 Tesla Model 3 Standard Range Plus lies beneath the surface – the battery. Moving away from the Lithium Nickel Cobalt Aluminum (NCA) battery of the 2019 model, the 2021 Tesla adopts a Lithium Iron Phosphate (LFP) battery pack manufactured by CATL. While NCA batteries (produced by Panasonic and LG Chem) are more energy-dense and lighter, LFP batteries offer compelling advantages: enhanced safety (more stable chemistry), longer lifespan (more charge cycles before degradation), and the ability to be charged to 100% without concern for long-term battery health. Tesla opted for LFP in the Standard Range Plus due to sufficient space within the vehicle to accommodate the slightly larger and heavier LFP pack.
The real-world implications of the LFP battery are substantial:
- Increased Daily Range: The 2021 Tesla boasts a greater indicated range at 100% charge – 423km compared to approximately 380km in my 2019 model, providing more confidence for daily driving.
- Charging Flexibility: Concerns about optimal charging practices are minimized. The LFP battery thrives on being charged to 100%, eliminating the need to manage charging levels for daily use versus trips, or worry about potential battery degradation from frequent full charges.
- Consistent Range and Longevity: After 10,000 km, my 2021 Tesla still indicates the same 423km range as day one, showing no signs of degradation, highlighting the robust nature of the LFP battery.
Furthermore, Tesla has refined the battery management system, particularly regarding regenerative braking. In the 2019 model, regenerative braking was limited when the battery was charged to 100%, altering the driving feel. The 2021 Tesla LFP battery provides consistent regenerative braking behavior regardless of the charge level, offering a more predictable and seamless driving experience – another crucial factor for broader EV acceptance.
Conclusion: The 2021 Tesla Model 3 SR+ – A Mass-Market EV Leader
The enhancements in the 2021 Tesla Model 3 Standard Range Plus, especially the robust LFP battery, represent a significant leap forward for mass-market EVs. The “charge it, drive it, repeat” simplicity afforded by the LFP battery, eliminating range anxiety and complex charging considerations, is transformative. The removal of the daily/trip charge distinction in the charging interface (as seen in the image above) perfectly encapsulates this simplified ownership experience. No more concerns about regenerative braking inconsistencies or unexplained range reduction.
For mass EV adoption, these improvements are not just incremental – they are fundamentally critical.
The 2021 Tesla Model 3 Standard Range Plus isn’t just an upgrade; it’s a maturation of the platform, making EV ownership more accessible, user-friendly, and worry-free than ever before.
