Quick answer

Among 218 sedans and coupes with a similar-sized cabin, the average is 14.6 cu ft, so the GS carries less than 99% of them. It gives 4.8% of its interior to luggage, one of the smallest shares we measure. A folded stroller will not fit alongside luggage.

What actually fits in a GS

The trunk shrank from 13 cu ft in 1994 to 5 cu ft in 2021. The biggest single change came in 2021: −9 cu ft against the 2020 car.
