Trunk comparison: Jeep Avenger Electric vs Opel Astra Wagon

Key Differences
The Opel Astra Sports Tourer offers significantly more loading length and usable interior space than the Jeep Avenger Electric: the trunk is +17.3 in (33%) longer with the seats folded down and +13.8 in (52%) longer with the first row of seats upright.
The depth of the trunk (loading edge to floor) is +1.2 in (27%) greater in the Astra. Additionally, the width at the narrowest point is +4.7 in (13%) greater in the Astra. In contrast, the Jeep Avenger has a higher loading edge: it is +4.3 in (18%) higher above the road than the Astra.
Two other differences are less pronounced: the height of the trunk opening (+2.4 in / 8%) and the width of the trunk opening (+3.1 in / 8%) — both are below the 10% mark and therefore have less impact.
Impact on Usability
Due to the greater length extension and greater depth, the Opel Astra Sports Tourer is better suited for long or bulky transports (e.g., slats, skis, furniture parts) as well as for larger amounts of luggage on vacation trips.
The greater minimum width makes loading wide items easier and reduces the risk of cargo getting stuck in tight spots.
The higher loading floor of the Jeep Avenger increases the physical strain when lifting heavy items into/out of the trunk and complicates handling large, heavy luggage.
At the same time, a higher loading edge can offer advantages in some everyday situations (e.g., on wet roads or light off-road), but purely from a cargo space perspective, it is a disadvantage.
Conclusion: Those who regularly transport long, wide, or bulky loads or plan family vacations with lots of luggage will find the Opel Astra Sports Tourer the more practical choice.
For buyers who prioritize loading height or a more compact overall concept, the Jeep Avenger remains relevant — but purely in terms of trunk usability, the Astra is clearly more advantageous.
