Frunk
A front trunk: storage space under the hood of some electric cars, where an engine would otherwise sit. Size varies by model and model year.
Remove the engine and the space under the hood becomes negotiable. A frunk, short for front trunk, is a storage compartment ahead of the cabin. Ford describes the one in its Mustang Mach-E as located under the hood, where an engine would typically be. Some electric cars offer one.
Its everyday appeal is separation from the main cargo area. Sizes differ by model, and even within one model. As of September 2026, Ford's page lists the Mach-E frunk at 4.7 cubic feet for model year 2024 and earlier and 2.6 cubic feet for 2025 and newer.
Not every EV offers one, and packaging choices vary by manufacturer, so the absence of a frunk is not a defect. Check the specification of the exact model and model year if a front compartment matters to you, and compare figures only when they are quoted by the same method.
