Pillarless Hardtop
A pillarless hardtop has no fixed B-pillar between the front and rear side windows, giving an open look when the windows are down.
What is Pillarless Hardtop?
It was popular in the 1950s to 1970s. Some modern coupés use a similar frameless design. Window seals are critical to stop leaks and wind noise. Frameless door glass on modern cars drops slightly when the door opens to seal properly.
How it works
The roof is supported at the front and rear, while the side windows meet each other without a pillar.
Why it matters for your car
Adjust windows and seals carefully to avoid leaks. Side impact protection is lower than with a full B-pillar.
