2009 BMW 750i: The Trunk of a Crossover?
January 21, 2010
Our 2009 BMW 750i has a meager 14.0-cubic-foot trunk capacity and a ski pass-through, but no folding seat. So you might think our sedan is pretty useless for hauling compared to most luxury crossover SUVs and the emerging population of luxury hatchbacks (5 Series Gran Turismo, Audi A7).
Today, though, I got out my tape measure and, unofficially, found the 750i's trunk competitive with the cargo bay of a 550i GT I measured recently.
This isn't that surprising, mind you, given that the Gran Turismo has only a 15-cubic-foot bay until you fold its reat seats (--> 60 cubic feet). But I think it's a relevant comparison, given that the two cars share the same platform architecture and have nearly the same wheelbase (120.9 vs. 120.7), the same track width (63.4 front, 65.1 rear), and the same overall width (74.9). Our 750i is 3 inches longer overall -- 199.8 inches. Also, BMW is targeting a similar buyer with these cars... the difference might come down to a Labrador.
Here are the numbers. For width, I'm giving you a range from the narrowest point to the widest. And for height, it's the lowest-clearance point to the highest.
750i 550i GT
Liftover height, in. 27 27 3/4
Depth of trunk/bay, in. 43 3/4 36
Width of trunk/bay, in. 31 -- 54 40 3/4 -- 52 3/4
Height of trunk/bay, in. 19 1/4 -- 20 1/4 13 -- 26 3/4
