The next-generation Hyundai Elantra has been spied testing, and we can begin to make out the quirky new design that's hiding beneath the camouflage.Thin LED light bars at the front and rear meet up with perpendicular elements on the outer edges, and a small triangular window sits behind the C-pillar. We expect to continue to see a range of four-cylinder engines under the hood, as well as a hybrid variant, when the Elantra arrives next year.
