The Hyundai Nu engine was introduced in the 2011 Hyundai Elantra to replace the previous Beta engines. It was designed to fill the gap between the new Gamma 1.6L and the 2.0L Theta II.
The 1797cc Nu features a bore x stroke of NaNmm with a compression ratio of 10.3:1 or 10.5:1 depending on the revision. This engine features[1] MPI, and Dual-Continuous Variable Valve Timing aka D-CVVT. Power output is NaN0NaN0 at 6,500 rpm with NaN0NaN0 of torque at 4,700 rpm.[2]
Hyundai Nu engine Specification:
The Nu 1999cc version of this engine features the same 81mm bore but with a longer stroke of 97mm. First revision of the G4NA engine makes 1660NaN0 @ 6,500 rpm and 20.50NaN0 at 4,800 rpm while later revisions produce NaN0NaN0 @ 6,200 rpm and NaN0NaN0 at 4,500 rpm.
Primary change is adding the CVVL, the engine produces 1720NaN0 @ 6,700 rpm and 20.50NaN0 at 4,800 rpm.
The Atkinson Cycle version of the Nu MPi 2.0L was first released for the sixth generation Hyundai Elantra, compression ratio is 12.5:1 and it produces 1490NaN0 @ 6,200 rpm with 18.30NaN0 of torque at 4,500 rpm.
The engine promises improved fuel economy vs the Nu MPi 2.0L (G4NA) engine and better thermal efficiency.
The Nu GDi 1999cc version of this engine features the same 81mm bore but with a longer stroke of 97mm that produces 1760NaN0 at 6,500 rpm with 21.70NaN0 of torque at 4,700 rpm.
Flex fuel compatible engine of the Nu MPi.
The Nu FLEX 1999cc engine makes 1670NaN0 at 6,200 rpm with 20.60NaN0 of torque at 4,700 rpm.
The Nu MPi Hybrid version of this engine combines a 2.0L engine with an electric motor and a battery, the petrol engine makes 1500NaN0 at 6,000 rpm with 18.30NaN0 of torque at 5,000 rpm.
The Nu GDi Hybrid version of this engine combines a 2.0L engine with an electric motor and a 1.76KWh battery, the petrol engine makes 1560NaN0 at 6,000 rpm with 19.30NaN0 of torque at 5,000 rpm while the electric motor makes 520NaN0 with 20.90NaN0 of torque for a combined power rating of 2050NaN0.
Uses Liquefied petroleum gas instead.
The Nu LPi 1999cc version of the engine makes 151- at 6,200 rpm with 19.8- of torque at 4,200 rpm.
On December 2, 2020, Hyundai and Kia recalled 423,000 vehicles equipped with various engines following a joint review by Hyundai and the NHTSA, of which the Nu GDi engines were a part of. Affected vehicles include the 2016 Hyundai Sonata Hybrid,[3] 2014-2015 Kia Forte and Forte Koup, and the 2014-2015 Kia Soul.[4]
