Elantra N is powered by a 2.0-liter, turbocharged, direct-injected four-cylinder engine with a 52-mm turbine wheel and a 12.5-mm turbine passage – with an area increased by 2.5 mm. These enhancements, along with the optimization of the shape and material of the cylinder block, improve both performance and durability it’s claimed. As a result, the so-called flat-power technology makes maximum output from 5,500 rpm for quick acceleration.
