About the VW Passat Variant 2024 boot
The Passat Variant is an estate, and its boot behaves like one. The opening is 41 3/8 inches wide by 31 1/8 inches tall, and the floor runs 44 1/2 inches with the seats up. Fold the rear bench and it stretches to 79 1/8 inches, a gain of 34 5/8 inches, which is where this car earns its keep. That long flat floor takes flat-pack boxes and long, low loads with ease, though the narrowest point is 39 3/4 inches, so very wide items still need care. The sill sits at 25 1/4 inches with a 3 1/2 inch drop, so slide heavy boxes rather than lift them.
About the BILLY Bookcase, black oak effect, 31 1/2x11x79 1/2 " package
The BILLY bookcase comes as a single long, flat box: 81¼″ × 11¾″ × 5″ and 86 lb 15 oz. It is the length that catches you out, not the weight on its own. That long panel wants a flat floor, which on most cars means folding the rear seats first. The board is rigid and will not flex around a wheel arch or a short boot, so it has to lie straight. An estate, a folded-seat hatchback, or an SUV takes it comfortably. Load it long-edge first, keep it flat, and guard the corners, because a knock at this weight cracks the edge.
