Tesla CEO Elon Musk is continuing to fuel our curiosity with new information about the supercar after sharing news that Tesla Roadster 2.0 will have rocket thrusters.
On Twitter, Musk tweeted that the wheels of Roadster 2 will have only one center-nut. He explained in his next tweet that the nut would be relatively growing.
A centerlock wheel is a type of car wheel for which the center of the rim has one nut, instead of the more common ring of 4 or 5 nuts or bolts.
Rudge-Whitworth first introduced the centerlock wheel and hub system in the early 1900s, for use in car wire wheels. The basic mechanism for “knock-off” type centerlock hubs was patented by 1908, originally called “QD” (meaning “quickly disconnectable”). Auto manufacturers and racers were quick to adopt it.
These type of wheels are used on many modern race cars like NASCAR and Formula One.
The use of a single-center nut allows greater space between the tire and engine hub. You may use the extra space to attach larger brake disks and calipers. Also, this is a major advantage for both road cars and racing cars, as they maximize the stopping power.
As an all-electric supercar, Roadster maximizes the aerodynamic engineering potential — with record-setting efficiency and effectiveness. The car achieves speeds of between 0 and 60 mph in a stunning 1.9 seconds, making it the world’s fastest production vehicle. So wheels with one central nut are a perfect addition to Roadster 2.0.
