Tesla remains a major player in the EV market, consistently introducing technological advancements. The updated Model Y features a refined design, improved technology, and enhanced comfort, positioning it as a strong contender in the SUV segment.
Performance and Range
The new Model Y Launch Edition includes a dual-motor Long Range All-Wheel Drive system, delivering an estimated 515 km of range. The model is expected to be available in March at a starting price of €56,700. If you are looking for something a little bit cheaper, Tesla continues to sell the previous Model Y version, which starts at €41,300 and offers a 542 km range for the rear-wheel-drive variant.
Model Y vs. VW ID.4 and BYD Sealion 7: A Comparison
Let's look at the Tesla Model Y, VW ID.4, and the Chinese-made BYD's Sealion 7, side by side.
Feature Comparison
| Feature | Model Y (2025) | VW ID.4 (2025) | BYD Sealion 7 (2025) |
|---|---|---|---|
| Design | SUV, light bar across hood, full-width rear lights | Compact electric SUV, modern European styling | SUV with aerodynamic improvements |
| Aerodynamics | Cd 0.23, optimized for efficiency | Cd 0.28, moderate efficiency | Cd 0.27, designed for balance of efficiency and performance |
| 4WD/AWD | Yes, AWD standard | Available in RWD and AWD | Available in RWD and AWD |
| Interior | Ambient lighting, rear touchscreen, powered rear seats | Digital cockpit, minimalistic design | Modern interior with advanced technology |
| Performance | 515 km range, Dual-Motor AWD | 520 km range, RWD & AWD options | Up to 550 km range, Single and Dual-Motor options |
| Technology | Enhanced suspension, Full Self-Driving option | Advanced driver assistance, VW infotainment system | Advanced driver-assistance, BYD's DiSus-C suspension |
| Price | €56,700 | Starts at €45,000 | Approximately €50,000 |
| Utility | More cargo space than VW ID.4 | Spacious cargo area, comfortable seating | Spacious with increased storage and seating comfort |
The Model Y has its perks, but overall the new VW or the BYD might give you a better bang for your buck. So, is the new Model Y worth it? Well, besides being the only self-driving car of the three, and in our opinion the most aesthetically pleasing, Tesla has something special in comparison to its competition: Aerodynamics.
Aerodynamics and Efficiency
Aerodynamics plays a crucial role in EV efficiency, and Tesla has optimized the Model Y's design to minimize drag.
- Sleek Body Shape: The Model Y features smooth curves and streamlined surfaces to reduce air resistance, enhancing efficiency at higher speeds.
- Low Drag Coefficient (Cd): The Model Y has a drag coefficient of approximately 0.23, making it one of the most aerodynamically efficient SUVs.
- Active Aero Features: An optimized front bumper and rear spoiler improve stability and efficiency.
- Underbody Design: A flat underbody reduces turbulence and enhances range while ensuring a quieter ride.
Detailed Aerodynamic Coefficients
We visualized the Model Y's refined aerodynamics using dicehub's simulation software. Check out how smooth the new Model Y really is:
Our CFD simulations revealed the following aerodynamic coefficients for the Model Y:
| Coefficient | Value | Description |
|---|---|---|
| Cd | 0.337 | Drag coefficient - measures the vehicle's air resistance. Lower values mean better aerodynamic efficiency |
| Cl | 0.168 | Lift coefficient - indicates upward force. A small positive value helps maintain stability |
| Cl(f) | 0.024 | Front lift coefficient - shows minimal front-end lift, good for handling |
| Cl(r) | 0.144 | Rear lift coefficient - slightly higher rear lift helps with stability at speed |
| Cm | -0.060 | Pitching moment coefficient - negative value indicates the car's tendency to stay planted on the road |
These values demonstrate Tesla's focus on aerodynamic optimization. The relatively low drag coefficient (Cd) helps maximize range and efficiency, while the balanced lift coefficients ensure stable handling at highway speeds. The negative pitching moment (Cm) indicates good stability characteristics, helping the vehicle maintain composure during high-speed driving.
Conclusion
Among the three, the VW ID.4 falls behind in overall performance and features. If affordability is your priority, the BYD Sealion 7 provides a futuristic design and solid capabilities at a lower cost. However, for those seeking superior comfort, premium interior features, and an aerodynamic advantage that enhances both efficiency and aesthetics, the Tesla Model Y stands out as the best option.
