Trunk comparison: BMW 5 Series Touring vs Tesla Model Y

Key Differences

Looking at the dimensions, one significant difference stands out: the usable width at the narrowest point is 13% (+4.7 in) larger in the BMW 5 Series Touring than in the Tesla Model Y.

Other differences are much smaller: the total volume/length with folded seats is about ~2% (+1.6 in) larger in the Tesla, and with the first row upright also about ~2% (+0.8 in) in favor of the Tesla.

The width of the trunk opening is about ~5% (+2 in) larger in the BMW. The Tesla's loading edge is higher (+6% / +1.6 in), the BMW's opening height is slightly (+0.4 in) larger; depth (loading edge to floor) is the same.

Impact on Usability

The significantly larger advantage of the BMW in the narrowest width makes it more practical for wide, bulky items (e.g., furniture parts, wide boxes, or larger sports equipment). Items measuring close to the narrowest width fit more often in the BMW without angled loading or disassembly.

The slightly longer cargo space of the Tesla with folded seats suggests better suitability for long but slender loads (e.g., slats, skis, long boxes). However, the difference of a few centimeters is minor and only affects everyday usability with very long items.

The higher loading edge of the Tesla (+1.6 in) increases the effort required to lift heavy items in and may complicate sliding large furniture pieces over the edge. The somewhat wider opening on the BMW additionally facilitates maneuvering wide parts during loading.

Since depth and opening height are practically the same, the usable interior height remains comparable; small differences here are hardly noticeable in practice.

Conclusion

For wide, bulky cargo, the BMW 5 Series Touring clearly has the advantage (most important difference: +13% in the narrowest width). For very long, slender items, the Model Y offers slightly more length. The higher loading edge of the Tesla can make loading and unloading heavy items more difficult.
