The Nu engine facilities an aluminum retard with a expel iron cylinder liner, cylinder conduct and crank. This singular pattern formula in a retard that is 30 percent lighter than an iron block, shedding some-more than 74 pounds off a whole engine weight, while still providing allied strength.

The 1.8-liter Nu also offers Dual Continuously Variable Valve Timing (D-CVVT) camshafts and hydraulic engine mounts for best power, potency and refinement. Using D-CVVT on both camshafts has several advantages when compared with regulating it only on a intake camshaft. They embody a dual percent alleviation in opening (increased volumetric efficiency), dual percent alleviation in fuel economy (reduced pumping loss) and a 30 percent rebate in hydrocarbon emissions. In a valvetrain, drum pitch arms and hydraulic lash adjusters revoke valve driven attrition to urge fuel economy one percent compared with approach valve driving. The Nu engine also facilities a maintenance-free wordless timing sequence complement to raise continuance and urge Noise Vibration and Harshness (NVH).

The focus of a cosmetic two-stage Variable Intake System (VIS), enables switching between prolonged and brief intake manifolds, ensuing in an across-the-board opening increase. These outcome in a 4 percent alleviation in performance, a 15 percent rebate in cost and 30 percent rebate in weight, when compared with aluminum.

Another apparatus Hyundai engineers have incorporated into a subsequent era Elantra is an electronic stifle control. The electronic stifle control replaces a required wire and automatic linkage found in a prior era Elantra with quick responding electronics. This complement accurately controls atmosphere intake and engine torque, improving drivability, response and fuel economy.

Hyundais initial focus of double-pipe plumbing (internal feverishness exchanger) is found in Elantra. Double-pipe plumbing improves cabin cooling performance, while minimizing a ability of a compressor, that serve reduces fuel consumption. An outmost tranquil non-static compressor is also used to urge fuel potency contra an inner non-static compressor.

The Nu four-cylinder engine also has an equivalent crankshaft pattern that reduces attrition between a piston and cylinder wall for a one percent alleviation in fuel economy.
