 | Bugatti Divo: Ultimate in personalized style
If owning a $3-million Bugatti Chiron hyper car -- the fastest and most powerful in the brand's history in 2019 -- is just too boring for you, the French carmaker has an almost $6-million extreme version called the Divo that could get you pumped. It takes Bugatti aerodynamics to new heights, and it adapts to customization so well that even if you bought a pair of Divos, they'd look like different cars. Plus you'll do 0 to 60 mph in under 2.5 sec.

 | How a camera auto-focus lens uses a special spring
Ultrasonic motors are small motors, some measured in millimeters, that are being used in a variety of applications including the auto-focus feature on a camera lens, side mirrors, surgical equipment, and robots. Learn how a single-turn closed wave spring is used to maintain the necessary pressure against the motor stator in a camera, and why it is a better choice in this application over coil or washer-type springs.

 | Moon buggy wheel tech evolves for Mars mission
The wheels from the lunar roving vehicle (LRV) for the Apollo 15, 16, and 17 moon missions were made of steel piano wire and titanium treads to give them a cushioning, non-rigid structure. Now NASA has taken that technology a big step further, using shape memory alloys to create tires for Mars rovers.

 | New programmable angle sensors
Novotechnik U.S. has just introduced the Vert-X 37E Series of programmable touchless rotary sensors that use a magnetic pick-up secured to the rotating object, so there is no direct mechanical linkage between the shaft and the measuring system -- and therefore no wear. The hermetically sealed Vert-X 37E Series can be programmed by customers or at the factory, so customers can order angle sensors optimized for their specific application. These sensors can help achieve time and cost savings by eliminating the need for other components to specify the angle end points, choose an intermediate plateau, sense of rotation function, CW or CCW, or create V-output.

 | 250-mph Speedtail is fastest McLaren road car ever
With a silhouette like something from a 1950s issue of Popular Mechanics, the new Speedtail is McLaren's fastest road car ever and its first Hyper-GT model. The 250-mph three-seater is way more than retro-futuristic chic, though. It provides a glimpse into the latest developments in lightweighting and hybrid-drive technology, featuring titanium woven into its carbon fiber, a Formula E-derived electric motor, and a special high-voltage battery design.
