When it comes to fun in the sun and open-air motoring, it’s tough to beat the convertible body style. However, with unlimited headroom comes an increased risk of injury in the event of a rollover, an issue many modern convertibles address with a deployable roll bar. By contrast, the 2020 Corvette C8 features extra-high-strength A-pillars designed to withstand 2.25 times the weight of the car, thus superseding the need for a complex, weight-adding roll bar.
In an interview with GM Authority, Corvette Chief Engineer Tadge Juechter laid out some of the details on why the 2020 Corvette doesn’t need additional rollover protection in the form of a deployable bar.
“We designed the windshield pillars to hold 2.25 times the weight of the entire car. So you can turn the car upside down, and you can put another car on top of that, and still have room to spare,” Juechter said. “So it’s essentially a super strong roll bar,” he added, referring to the A-pillars.
To note, this applies to both the 2020 Corvette Convertible and the 2020 Corvette Coupe, with both body style variants featuring the same ultra-high-strength A-pillar design. The commonality makes sense given that the Corvette Coupe features a removable hard top panel.
The high-strength construction of the A-pillars also speaks to the overall strength and rigidity of the 2020 Corvette platform. Indeed, the high-strength construction also benefits other areas of the car beyond crash protection, such as enabling improved handling by way of precise tuning of the suspension system.
As we covered before, the 2020 Corvette Convertible is actually ready for track duty right out of the box without any additional rollover protection needed, which is sure to delight those buyers looking to mix open-sky motoring with the occasional outing at the local race circuit. This also stands in contrast to the Corvette C7 Convertible, which did not offer the necessary rollover protection for track driving, without aftermarket upgrades.
