10 of the coolest concept cars revealed this year

Car makers are getting more tech savvy lately. Or at least their concept cars are making them appear that way.

Just last week at the International Motor Show in Frankfurt, manufacturers from Volkswagen to Mercedes-Benz showed off their futuristic concept cars.

The selection was impressive, with a mix of electric and hybrid cars. The vehicles were equipped with state-of-the-art features, which ranged from a holographic dashboard to solar powered roofs. Some of the concept cars could even be said to rival Tesla.

In no particular order, here are ten of the most impressive concept cars (not all are from the Frankfurt show) that have been revealed so far this year.
