Opel is aiming its Rocks-e at commuters in cities and at young drivers.
The two-seat full-electric microcar will go on sale in Germany in the autumn. Other markets will follow later, Opel said in a statement.
The Rocks-e is based on the Ami sold by Stellantis sister brand Citroen.
It car will be positioned below the Corsa small hatchback and will be priced at a level that nearly any driver can afford, from young beginners to urban commuters, Opel said.
The entry-level price for the Rocks-e will be siginificantly less than for a small car and the monthly leasing cost will be similar to that of a ticket for local public transportation, the brand said.
Opel did not disclose pricing. The basic version of the Ami costs 6,990 euros ($8,221) in France.
The Rocks-e is classed as a quadricycle because of its small size and low speed, so it can be driven from the age of 15 in Germany with a light motor vehicle licence and some other European countries.
