Cupra

Spanish performance brand Cupra used the International Mobility Show in Munich this week to unveil the DarkRebel EV show car. It's one of the most distinctive best looking concepts we've ever seen.

Cupra is preparing to get dirty in as clean a way as possible. Not only is its all-new Tavascan Extreme E Concept motivated by pure electric power, but it incorporates components and solutions designed to be flexible, adaptable and sustainable.

Austrian boatbuilder Silent Yachts has already gained a fair bit of attention with its solar electric catamarans. Its just-announced latest model should continue that trend, as it's the result of a partnership with automakers Volkswagen and Cupra.
