Options from every price point that will keep your rear-seat passengers the most comfortable.
We know the Rolls-Royce Phantom Extended is virtually unattainable for 99.9% of Americans, but we had to answer the question: which sedan has the most rear-seat legroom?
The "normal" Phantom still comes with a respectable 43.5 inches of legroom and 38.5 inches of headroom in the backseats; the Extended variant takes it to another level.
If you can afford another hundred-thousand dollars over its base $500k price tag, then you'll be gifted with a longer wheelbase that extends the rear-seat room to 53.1 inches.
