It said the move could affect 180,000 cars - not yet sold or registered - in the Euro5 emission category.

This comes after VW, the biggest carmaker in the world, admitted cheating on emissions tests in the US.

Meanwhile, Matthias Mueller has been named new VW chief executive in the wake of the scandal.

Mr Mueller, the former head of Porsche, succeeds Martin Winterkorn, who resigned on Wednesday.

The row erupted after it emerged that some VW cars being sold in the US had devices in diesel engines that could detect when they were being tested, changing the engine performance to improve results.

The US Department of Justice (DoJ) told the BBC that it would join the US Environmental Protection Agency's (EPA) investigation into VW.

The ban was announced by the Swiss Federal Roads office on Friday.

In a statement, it said vehicles that have 1.2-litre 1.6-litre and 2.0-litre diesel engines of VW models - including VW's Audi, Seat and Skoda brands - could be affected.

The ban does not apply to vehicles that are already in circulation or cars with Euro6 emission category engines.

The Swiss authorities have also set up a taskforce to fully investigate the issue.

A spokesman for the British department for transport said there were no plans for ban in the UK.

After his appointment, Mr Mueller said restoring the company's reputation was his top priority.

"My most urgent task is to win back trust for the Volkswagen Group - by leaving no stone unturned and with maximum transparency, as well as drawing the right conclusions from the current situation."

He also announced sweeping changes to the way the company was run, including handing greater autonomy to regional divisions.

He said he would tighten up procedures at the company: "At no point was the safety of our customers in danger. We will now have even stricter compliance. Our objective is that the people continue to use and drive our vehicles with confidence and pleasure. That's 80 million people driving our cars worldwide."

The EPA's findings of the scandal cover 482,000 cars in the US only, including the VW-manufactured Audi A3, and the VW brands Jetta, Beetle, Golf and Passat.

But VW has admitted that about 11 million cars worldwide are fitted with the so-called "defeat device" - 2.8 million of them in Germany - and further costly recalls and refits are possible.

Half of the company's sales in Europe - VW's biggest market - are for diesel cars.

VW shares plunged around 30% in the days after the scandal broke.

It's certainly not a big update, but it will allow a small group of people who were unable to upgrade to iOS 9 finally get the latest iPhone operating system. That unresponsive "Slide to Upgrade" bug was annoying to people who were eagerly waiting to get iOS 9, but couldn't.

Apple (AAPL, Tech30) made the new iOS available in a public beta for the first time this summer, allowing people to test out the new software. In theory, that should have helped reduce the number of bugs at launch.

Compared to previous versions of iOS, iOS 9 is (so far) pretty bug-free. The biggest problem so far was Apple's inability to satisfy demand, giving thousands of people headaches when they were unable to contact Apple's servers to download the new operating system.

Eventually, people were able to get the upgrade, however. In fact, Apple said iOS 9 has the fastest adoption rate of any iPhone operating system in history.

HOLLYWOOD, Calif. -- It's finally happening: After decades of development, virtual reality will be landing on store shelves this November.

The excitement is palpable. Rock stars of the video game industry are singing the technology's praises. The world's most powerful technology companies have announced plans to offer competing products. Facebook spent $2 billion to buy one of the industry's largest companies last year. And analysts are estimating significant growth, with up to 30 million headsets shipped annually around the globe by 2020.

There's reason for the interest. The VR industry is at the beginning of what could be the next major technology trend, with the potential to change the way people live, work and communicate. That potential has attracted billions of dollars in capital, which is being funneled into startups creating video games, educational apps, communications services and business programs.

The promise of being able to put a pair of computer-connected goggles on your head and suddenly feel like you've been transported to another world is compelling.

That's probably why Mark Zuckerberg, Facebook's CEO, stood on stage earlier this week at the Oculus Connect conference here to deliver a message: Manage your expectations.

"This is going to grow slowly," he warned. "If you think about the arrival of computers or smartphones, the first units shipped did not ship tens of millions in their first year. But they proved an idea and made it real."

Other Oculus executives said similar things, telling attendees who are creating video games, movies and experiences for this nascent technology that there's still a long way to go. Michael Abrash, a celebrated game maker and chief scientist at Oculus, said decades of innovation are still to come and a lot of research is still needed to improve the technology. "We've barely started down the path of what The first VR product, Samsung's Gear VR headset that works with flagship smartphones like the Note 5 and Galaxy S6, will be on sale in less than two months, for $99 apiece. Soon, consumers will be able to go to a local shop and experience VR apps and games for the price of a high-end smartphone case.

But a rising concern is that the hype following this technology could push expectations too high, ultimately disappointing investors and analysts who fund these startups and shape public opinion. If a slow start is seen as a flop, executives fear it could have wide-ranging impacts on the industry.

"You have to get past the hype," said Brian Blau, an analyst at Gartner. A VR pioneer himself more than a decade ago, Blau has begun telling companies that they need to treat the industry like a business and have reasoned expectations for how quickly it will grow. "Focus on the reality." he said.That doesn't mean executives aren't still excited. In his speech Thursday, Zuckerberg repeated earlier statements that VR could be like the next smartphone, a platform upon which developers created apps and services that have changed commerce, communication and media. "In just a few years, VR has gone from a science fiction dream to an awesome reality," he said. "All of you are inventing the next major platform."
