An InsideEVs report describes a common comfort compromise in low electric sedans: battery packs beneath the cabin can raise rear footwells, pushing passengers’ feet and knees upward. Some automakers address the issue with recessed footwells or by moving battery modules away from the rear seating area, often with a tradeoff in battery capacity or packaging flexibility.
An InsideEVs report highlights a design compromise in low electric sedans: battery hardware beneath the cabin can raise the rear footwell, leaving passengers’ feet high and their knees and thighs poorly supported. The issue matters to buyers who regularly carry adults, even when a car appears to offer adequate legroom, headroom and shoulder room on paper.
The report’s author describes sitting in the back of electric sedans with ample apparent space between the knees and front seat, yet feeling folded because the floor sits high beneath the feet. When the feet cannot rest low, the thighs may lift off the seat cushion and the knees can feel as if they are hanging without support. That is a reported seating experience, not a claim that every electric sedan has the same problem.
The cause is the underfloor battery pack, including its cells, enclosure, protection and cooling equipment. A skateboard-style layout places the battery low in the vehicle, which helps keep a heavy component near the ground and avoids using trunk or cabin volume for a large pack. But the pack adds thickness beneath passengers. In a low sedan, raising the rear seat to match the floor can leave occupants too close to the roof; raising the roof can undermine the intended low profile.
The report points to several engineering responses. Porsche used recessed areas in the Taycan’s battery for rear passengers’ feet, and the Audi E-Tron GT shares that approach. The Lucid Air Pure and Touring are described as leaving battery modules out of the rear footwell area, while the report says higher-capacity Air versions have less rear foot space. Jaguar’s Type-01 and the Polestar 5 are also cited as using battery arrangements that preserve space beneath rear passengers.
Rear-Seat Comfort Shapes Sedan Choices
Rear-seat comfort can affect whether an electric sedan works for a household, ride service or anyone who often carries adult passengers. A vehicle can have an attractive driving position and a low center of gravity yet still feel uncomfortable in the back if the footwell forces occupants into a cramped posture. The report’s central point is that legroom measurements alone may not reveal thigh support.
Packaging choices also involve tradeoffs. Moving cells away from the rear footwell can preserve a more natural seating position, but the report says this may mean less total battery capacity. Buyers comparing sedans may need to weigh passenger comfort against range and battery size, rather than assuming those goals can all be met without compromise.
The practical advice is direct: before buying, set the front seat to the position the driver will actually use, then sit in the rear and check whether the seat cushion supports the thighs. A quick inspection can reveal a comfort issue that a specification sheet may not communicate.

Battery Layouts Shape Cabin Space
The common skateboard arrangement places a broad battery pack under the cabin. That layout helps package a large energy store without placing it in the passenger compartment or trunk, while keeping its weight low. The same feature that makes the layout useful, however, can raise the floor relative to the seat and leave less room for rear passengers’ feet.
In 2019, Porsche design chief Michael Mauer discussed the Taycan’s “foot garages”: recesses in the battery area that give rear passengers lower places for their feet. The InsideEVs report says the solution helped Porsche balance a low roofline with usable rear foot space. Other designs shift modules elsewhere; Jaguar’s long hood, for example, gives engineers room to place battery modules toward the front, according to the report.
Volvo has said its SPA3 platform can leave cells out from beneath passengers’ feet, potentially allowing a lower electric wagon, but the supplied report says Volvo has not committed to building one. These examples show that rear-seat packaging depends on the vehicle’s architecture; they do not establish that one arrangement is best for every model.
““We solved this with so-called ‘foot garages’.””
— Michael Mauer, Porsche design chief during Taycan development, as quoted in the InsideEVs report
How Common Is the Seating Problem?
The supplied report does not provide measurements comparing rear footwell heights, thigh support, passenger comfort or battery capacity across the vehicles mentioned. It also does not establish how widespread the problem is across the electric-sedan market. The author’s account is based on reported experience and design examples, not a controlled survey of owners or a standard comfort test.
Details of the tradeoffs vary by model. The source does not quantify how much battery capacity is lost when modules are moved away from passenger footwells, nor does it give comparable range figures for the designs discussed. Volvo’s possible SPA3 packaging benefits are described as a platform capability; a wagon using that layout has not been confirmed in the supplied material.
Check the Rear Seat Before Buying
The report does not announce a new vehicle, recall or confirmed product change. For prospective buyers, the immediate next step is a rear-seat test fit: set the front seat to its normal driving position, sit behind it and check foot placement, knee position and thigh support. This is especially relevant for people who expect adults to ride in the back regularly.
Future models may use recessed battery footwells, relocate modules or adopt thinner packs, but the source does not give a timeline for broader changes. Whether manufacturers will prioritize lower rear floors over battery capacity or other packaging goals remains to be seen.
Key Questions
Why can the back seat of an electric sedan feel cramped?
A battery pack beneath the cabin can raise the rear footwell. That may lift passengers’ feet, push their knees upward and reduce thigh support, even if the car seems to have adequate legroom.
Do all electric sedans have this problem?
No. The report describes a packaging challenge, not a condition in every model. It cites designs that use recessed footwells or move battery modules away from the rear passenger area.
How does Porsche make more room for rear passengers’ feet?
The Taycan uses recessed areas called “foot garages” in the battery area, according to Michael Mauer, Porsche’s design chief during development. The recesses give rear passengers a lower place to put their feet.
Can improving rear foot space affect range?
It can involve a battery-capacity tradeoff. The report says leaving more room beneath passengers’ feet may mean a lower-capacity pack, but it does not provide figures comparing range or capacity across the examples.
What should I check during an electric-sedan test drive?
Set the front seat as the driver would normally use it, then sit in the rear. Check whether your feet rest comfortably, your knees have room and the cushion supports your thighs.
