This year’s Consumer Electronics Show (CES) in Las Vegas saw automakers unveiling their self driving cars. Auto manufacturers also used the CES platform to showcase hydrogen fuel cell vehicles.

Mercedes Chief Executive Dieter Zetsche unveiled the self-driving Mercedes-Benz F 015 concept vehicle at the 2015 Consumer Electronics Show in Las Vegas.

Costantine Samaras, a professor of engineering at Carnegie Mellon University said, “CES is a place where automakers can reach an entire new audience of consumers who are looking for what’s next. Even if it’s just at the concept level, there’s a lot of spillover for technology up and down an automaker’s supply chain.”

The car can accommodate four persons facing each other in a lounge-style seating while the car drives autonomously. It is just 15 years in future.

Toyota unveiled its self driving prototype last year’s CES event and this year it is showcasing the Hydrogen fuel cell vehicle. Toyota magnanimously announced that 5600 of its patents related to Hydrogen Fuel Cell will be free to anyone who wants to use them.

Toyota Senior Vice President Bob Carter said, “The first-generation hydrogen fuel cell vehicles, launched between 2015 and 2020, will be critical, requiring a concerted effort and unconventional collaboration,”.
