Trunk comparison: Jeep Renegade vs Tesla Model 3

Key Differences
In the volume comparison, it is particularly noticeable that the Tesla Model 3 is significantly longer: with the seats folded down, the Model 3 has a cargo area that is +13.4 in (22%) longer, and with the front seats upright, the Model 3 is +11.8 in (39%) longer than the Jeep Renegade.
The Jeep, on the other hand, offers a significantly higher trunk opening: the opening is +14.6 in (71%) higher.
Additionally, the distance from the loading edge to the trunk floor in the Renegade is +1.2 in (27%) higher and the loading edge itself is +3.5 in (13%) higher above the road than in the Model 3. Width differences are minimal (±1–0.8 in) and therefore negligible.
Impact on Usability
The longer interior dimensions of the Model 3 make it better suited for long items (e.g., skis, boards, long furniture parts) and for a larger usable cargo area when the rear seats are folded down.
The lower loading edge and smaller depth from loading edge to ground in the Model 3 also make it easier to lift heavy items into the vehicle and to load with rolling carts or trolleys.
The Renegade scores with significantly more vertical space at the opening and a deeper cargo well: tall or bulky items (e.g., stacks of boxes, plants, tall crates) can be better accommodated due to the greater opening height.
However, the higher loading edge makes lifting heavy loads into the vehicle more difficult compared to the Model 3.
Conclusion
For transport tasks that require length and easy lifting into the vehicle, the Tesla Model 3 is more advantageous. For transports with increased height requirements or when a larger vertical pass-through opening is important, the Jeep Renegade is better suited.
