New car industry start-up Mindset, has announced plans to sell a gasoline-electric hybrid next year. The 2+2-seater hybrid, called the Six50, boasts an electric-only range of 100km (62 miles) via a built-in Li-Ion battery. A two-cylinder gasoline motor, which kicks in as a generator as required, boosts the range to 800km (496 miles). Battery charging is further assisted by integrated roof-top solar panels.

That thing just seems very practical. It's a bit on the pricey side at ~$50k, though.
