Trunk comparison: Jeep Renegade vs Mercedes Benz CLA Shooting Brake

Key Differences
The Mercedes‑Benz CLA Shooting Brake offers significantly more cargo length: +9.8 in (16%) when all seats are folded down and +11.4 in (38%) with the front row upright. Additionally, the trunk depth (loading edge to trunk floor) in the CLA is +3.1 in (57%) greater.
In contrast, the Jeep Renegade has a higher trunk opening and a larger loading opening: the opening height is +7.1 in (25%) higher in the Renegade, and the width of the trunk opening is +4.3 in (13%) larger.
Smaller differences include the Renegade's loading edge being 0.4 in higher and the narrowest trunk width being 9% narrower in the Renegade (both under 10% and thus less relevant).
Impact on Usability
The CLA Shooting Brake clearly has the advantage due to the greater cargo length and significantly deeper trunk when it comes to transporting long items, flat pallets, or a higher overall cargo capacity.
Folded rear seats result in measurably more usable length in the CLA; the deeper loading volume also allows better stacking of suitcases or boxes and more usable floor space.
The Renegade scores points in handling bulky, tall, or irregularly shaped cargo: the higher trunk opening and wider loading opening make it easier to load large or bulky items (e.g., furniture parts, bicycle frames, plants) because there is more vertical and lateral clearance when loading.
The slightly higher loading edge (+0.4 in) is practically negligible.
Practical recommendation: Those who regularly transport long items or a lot of luggage and value loading volume benefit more from the CLA Shooting Brake. Those who more often load bulky, tall, or awkward individual pieces and need easier access/loading comfort are better served by the Renegade.
Summary
CLA Shooting Brake = more cargo length and deeper loading floor → better for volume and long loads. Renegade = higher and wider opening → better for bulky, tall, or irregular cargo and easier loading.
