Few mechanical failures hit a driver’s wallet harder than a dead transmission. One widely used type of automatic gearbox, the ...

Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems ...

The first continuously variable transmission fitted to an automobile actually has its roots in the late 19th century, though the technology has only become popular in the last two decades or so. While ...

We talk a lot about quantum computation and quantum key distribution here at Ars, but when we do this, we’re usually talking about a discrete logic system. That is, the quantum system uses a set of ...

Set to debut in a new 1.6-liter 4-cylinder Smartstream turbo engine, Hyundai's new valve tech is able to continuously change the duration of valve openings to suit driving conditions, which Hyundai ...

Hyundai figured out continuously variable valve duration in a production vehicle (or at least one about to hit production). increase in performance of 4 percent with 5 percent better efficiency, along ...
