Trunk comparison: BMW 3 Series Touring vs Seat Tarraco

Key Differences

Several differences in the trunk of the SEAT Tarraco compared to the BMW 3 Series Touring are clearly pronounced:

• Length with front seats upright: +4.7 in (12%) — more usable loading length without folding seats down.
• Height of the trunk opening: +4.3 in (15%) — greater installation depth for tall items.
• Depth (loading edge to trunk floor): +2 in (500%) — significantly deeper cargo area section behind the loading edge.
• Loading edge height above the ground: +5.9 in (25%) — the loading edge sits noticeably higher.
• Width of the trunk opening: +5.9 in (15%) — wider opening for bulky cargo.

Smaller differences (not highlighted): length with seats folded +4.7 in (7%), width at the narrowest point +2.4 in (6%).

Impact on Usability

The larger dimensions of the Tarraco make it more practical for bulky or tall cargo: the wider and taller opening as well as the increased cargo depth allow loading and storing larger items (e.g., furniture parts, strollers, bulky boxes) without or with less folding of the seats.

The longer loading capacity with the rear bench upright allows longer items to be transported while passengers remain in the back seats.

The higher loading edge of the Tarraco works in the opposite direction: due to the loading edge being about 5.9 in higher, lifting heavy items into the cargo space is more strenuous than in the BMW, where the loading edge is lower.

The deeper loading edge to floor distance (greater "depth") ensures that cargo sits further inside the vehicle — this increases packing stability and makes better use of the volume but can make reaching items located far back more difficult.

For everyday tasks involving frequent lifting of heavy suitcases or shopping bags, the BMW with its lower loading edge is easier to handle. For occasional or bulky transports (long, tall, or wide objects), the SEAT Tarraco clearly has the advantage.
