The Geneva Motor Show is the most important auto show of the year, where manufacturers wow us with their most impressive ideas. Some of the cars on display are being revealed to the public for the first time, while others are simply being shown for a second or even third time. We've taken a look at our favorite concept cars from the 2018 show. None are production ready yet, but all of them deserve to be green lit and we hope to see them on the road soon.BMW M8 Gran Coupe
BMW was already in our good graces after it announced the return of the 8 Series Coupe. While we wish the company would have announced a production version of the new 8 Series, we'll settle for a concept version of the new M8 Gran Coupe. True to BMW's naming conventions, the M8 Gran Coupe is a four-door-coupe M variant of the already stunning 8 Series. This will likely be BMW's new flagship car and we can't wait to see what it looks like when it reaches production.Toyota Gazoo Racing Supra
The Gazoo Racing Supra Concept was another spectacular, if not slightly disappointing, reveal. We were excited to finally see a production version of the new Supra, but all we got was yet another concept car. Just like with the Acura NSX, the wait for the new Supra is starting to become tiresome. Even if all we got was a concept, it would have been more effective to show off the road-going Supra rather than the race version. We still don't know what the real Supra will be like or how much it will cost. Enthusiasts can only wait so long for a car before it starts to become boring.Porsche Mission E Cross Turismo
When it comes to getting us excited for a production car, the Porsche Mission E Cross Turismo may have been the best concept at the show. Instead of just showing some futuristic metal, Porsche brought out a nearly production ready car accompanied with actual performance figures. The Mission E Cross Turimso will have over 600 horsepower from its EV drivetrain. 0-60 mph will take less than 3.5 seconds and the 120 mph top speed will take just 12 seconds to hit. We didn't think a high riding version of the Mission E could impress us this much, but Porsche did it right.Aston Martin Lagonda Vision
Aston Martin gained a lot of attention by revealing a track-only version of the Valkyrie at Geneva, but that wasn't the brand's only surprise. The company also showed off the Lagonda Vision Concept: a preview of the brand's luxurious EV models. Lagonda has two vehicles planned by 2023, one of which will be a four-door Rolls-Royce Phantom rival inspired by this concept car. We believe an EV drivetrain may be the only path to matching the smoothness of a Rolls-Royce V12. We can't wait to see the first production Lagonda in 2023.Hyundai Le Fil Rouge Concept
So far, all of the concept cars on this list are slated to reach production in some form. It is doubtful that our next two concepts will ever be seen on the streets, but this doesn't mean they aren't awesome. The Hyundai Le Fil Rouge Concept was built to show off the company's future design language known internally as ‘Sensuous Sportiness.' If this is how future Hyundai models will be styled, count us impressed. We doubt any future Hyundai models will end up looking this interesting, but it does give us plenty of hope for the company's future.Pininfarina HK GT
The final concept car on our list wasn't actually built by a car manufacturer. Instead, it was built by Italian design house Pininfarina. The HK GT Concept was built for the Hong Kong-based Hybrid Kinetic Group. This 2+2 electric grand-tourer has 1,072 hp and can hit 60 mph in just 2.7 seconds. No production version was announced, but Pininfarina did show off a production version of the hydrogen-powered H2 Speed. It may be a long shot, but the HK GT Concept could eventually reach production.
