The Koenigsegg Regera car had its debut around two years ago. It literally shocked the world when it was announced that the new Koenigsegg addition would come without a transmission. Yeah folks, no CVT, no gears, nothing! This can be overwhelming for many. Fortunately, Jason Fenske, host of Engineering Explained comes to the rescue. He is here to give us a full rundown on how the Koenigsegg Regera can run at all, not to mention reach 250mph, without a transmission. With some pretty neat math, Jason explains how the system called “Direct Drive” can spin the wheels. A hydraulic coupling connects the 5.0L V8 engine to the final drive.
Once the Koenigsegg Regera car reaches more than 30mph, this system works most efficiently. Till then, the drive electric system manages propulsion. Jason explains this with working equations when it comes to wind and tire resistance by using an arbitrary speed at 160mph. In order to spin the tires at such a high speed, the Regera requires 2,368 pounds of powerful force. At that point, 601 pounds of aerodynamics and rolling resistance are applied to the hypercar. The engine alone can`t provide the needed amount of torque in order to perform a burnout at staggering 160mph without a transmission. However, no fret, that`s why the Regera features additional three electric motors that deliver 663.9 lb-ft of torque!
