The Swiss know how to make a splash.

Porsche 918 Spyder Concept

What it is: What happens when Porsche thinks about building an efficient supercar.

Cool Features: As if the 500-horsepower V8 wasn’t enough, two electric engines are mounted at the front and rear axles that add 218 horsepower. That equates to a 0-62 run of 3.2 seconds and 78 mpg. The coolest feature is that it could possibly be produced.

Bottom Line: So much want.
