A major perk of an electric powertrain is the amount of space it frees up. Five tall adults will be able to get comfortable easily in the Model S, thanks to its generous leg, head and elbow room. And the floor is completely flat, with no hump running down the middle, making it easy to get in and out of the back and gifting plenty of foot space to the rear middle-seat passenger.
Because there's no big petrol engine sitting up front you get storage beneath the front bonnet, complementing the enormous conventional boot at the rear. The rear boot is accessed via a wide-opening, powered hatchback tailgate and is as roomy as that of some estate cars; it dwarfs the luggage space of a Panamera and I-Pace.
There’s even a large well under the boot floor for additional storage, or you can fill that with the optional two rear-facing fold-out kids’ seats, turning the Model S into a seven-seater. If you need more luggage space, the rear seat has a 60/40-split folding arrangement.
Storage throughout the interior is generally good, with a huge central storage bin between the front seats and a decent-sized glovebox but, oddly, no door bins in the front or rear.
