There were tons of really cool cars at the 2014 Detroit Auto Show, but a few stood out amongst the rest — especially the incredible selection of concept cars. Nissan had a great showing with two of their conceptual designs and Honda's FCEV looks like it rolled straight out of a science fiction flick starring Tom Cruise. This list of five cars give us a glimpse of the future and by the looks of it, it's going to be full of top-speeds and unique lines.

Honda FCEV Concept

With incredibly sharp lines, a lean profile and a slick look overall, the Honda FCEV is one of the most visually stunning rides shown at Detroit this year. Being fueled by hydrogen not only sounds futuristic, but the FCEV makes it look the part as well.

Kia GT4 Stinger

Looking like the lovechild of a '60s Corvette and an Audi R8, the GT4 Stinger is one of the most captivating concepts released by Kia to date and was chosen to be the Autoblog Editors' Choice of the 2014 Detroit Auto Show. It also has a pretty slick user interfaces that integrates projected glass gauges.

Nissan Sports Sedan Concept

How about 240 horsepower, 240 lbs/ft of torque, and a 1.8-liter direct-injection turbocharged engine attached to a six-speed manual transmission all wrapped in this seriously stylish exterior? Nissan has a winner on its hands with their Sports Sedan Concept — which should replace the Maxima as soon as possible.

Mercedes S Class Coupe Concept

A spectacularly modern profile with aesthetic touches that appear to be an homage to classic cars makes the Mercedes S Class Coupe Concept one of our absolute favorites. Facing more competition in the luxury market than ever before, Mercedes took some chances with the design of this S Class Coupe and have developed a 449hp twin-turbo V-8 that looks as elegant as it is powerful. 

Nissan iDX

This concept car from Nissan offers up an interesting take on the retro-modern fusion that's been embraced by cars like Ford Mustangs and Dodge Challengers. Instead of going for that tough and aggressive look from the '70s, the Nissan iDX seems to be more interested in the compact cars from that era.

Now, we know that everyone will have a different opinion on which is the coolest model, so sound off in the comments below on which cars you think were the best at this year's show!
