We shouldn’t know about the cars of the future yet, and let me be the first to say, I’m sorry they don’t fly. But the Opel E-Flex is a European concept of the Chevy Volt unleaded/electric hybrid. Other than its propensity to drink more wine and go “on holiday,” the Opel will use a 1.3lt turbo diesel engine to recharge the car’s lithium ion batteries when they run out.

Like the Volt’s unleaded offerings, the Opel E-Flex diesel engine is not a motor at all, but a backup power generator for the electricity-driven car. Let’s just swap out that diesel engine for a nuclear reactor, and we’re in business. Hit up Jalopnik for more photos.

Chevrolet’s electric powered Volt Concept has just discovered its European alter ego in the form of Opel’s, Frankfurt Show E-Flex Concept. The two concepts share the same basic architecture underneath their differently styled bodies. The only variation is that, whereas the Volt was equipped with a turbocharged, 1.0lt, three-cylinder gasoline engine, the E-Flex takes advantage of Opel’s 1.3lt turbo diesel engine. However, the basic principles remain the same as both models are powered by a front-mounted electric motor that runs on electric power until the Lithium-ion batteries are drained out.

Once that batteries are dead, the diesel engine kicks in to “feed” the onboard generator producing electricity while the car is operating. The electricity is then stored in the batteries. As with the Volt, the E-Flex’s Lithium-ion batteries can be recharged by plugging into an electrical outlet. We’ll have more on the E-Flex as soon as Opel releases all the details.
