On the outside, VW’s EcoRacer concept looks like any other sporty roadster. What makes this car stand out is a 100 k/w turbo diesel engine that pushes it from 0-60 in just 6.3 seconds. Not only does it look cool, this roadster/speedster gets 100mpg and has a top speed of 142mph (235 km/h). The carbon-fiber plastic roof is completely removable, allowing drivers to interchange between speedster and roadster configurations within a matter of minutes. More pics after the jump.
