The rumored car will fill the gap left by the Chevrolet Spark.

A new report finds General Motors' Opel division is in the early stages of developing a small, four-door hatchback designed to slot below the Adam city car in its lineup.

An entry-level car hardly fits with Opel's recent upmarket push, but it will help fill the void that will be left by the Chevrolet Spark once the Bowtie brand leaves Europe in late 2015. German magazine Auto, Motor und Sport claims the car will be built on an existing platform that currently underpins several models around the globe, indicating it might ride on a modified Spark chassis.

The yet-unnamed model will likely stretch approximately 145 inches long, 63 inches wide and 61 inches tall. It will offer space for up to four passengers while packing a wide array of high tech features such as a touch screen-based infotainment system in order to woo a young target audience.

Mechanically, the yet-unnamed model will be powered by an evolution of the new 1.0-liter SGE three-cylinder engine that will debut next year under the hood of the Adam and gradually spread throughout the Opel lineup. Made entirely out of aluminum, the gas-burning mill generates 115 horsepower and 112 lb-ft. of torque from 1,800 to 4,700 rpms thanks in part to a small turbocharger. The engine is equipped with direct fuel injection and variable valve timing.

If the rumor proves true, Opel's yet-unnamed four-seater will debut several weeks before the last Chevrolet dealer on the Old Continent closes its doors. With a base price of less than €10,000 (roughly $13,800), it will take on the next-gen Toyota Aygo, the production variant of the Suzuki A:Wind and the Kia Picanto.
