Hyundai, now a world-class engine manufacturer, may lend engine technology to Mercedes-Benz for a future four-cylinder powerplant. It was just a few short years ago that DaimlerChrysler, Mitsubishi, and Hyundai banded together in the Global Engine Manufacturing Alliance (GEMA) to build the so-called World Engine (pictured at right). The GEMA engine, with displacements ranging from 1.8-liters up to 2.4-liters, is found under the hood of more than a handful of Chrysler, Dodge, Jeep, Mitsubishi, and Hyundai products.
