Hyundai Elantra, what’s under the new hood?
The all new 2019 Hyundai Elantra is in showrooms right now. We take a closer look at its engine under the new designer hood and share with you some interesting facts. Powering the Elantra 2.0L is an all-new powertrain designed for improved fuel efficiency and everyday drivability performance. This engine is a 2.0-liter Nu MPI Atkinson four-cylinder engine producing a peak 152 horsepower at 6,200 rpm and 192Nm of torque at 4,000 rpm. This Atkinson cycle-type engine reduces pumping loss by delaying the close timing of the intake valve in the compression stroke, therefore maximizing the expansion ratio – it is the only Atkinson cycle engine to be combined with multi-port injection in the compact class. This greater expansion ratio is made more efficient by allowing additional energy to be produced. Furthermore, this engine features a high compression ratio of 12.5.
Other enhancements include intermediate valve cam phasing that increases the operational range of the intake valves and helps to reduce pumping loss. High energy ignition coils are also adopted to increase combustion efficiency through increasing spark intensity. A new electronically controlled thermostat decreases pumping energy and allows the thermostat to open at a higher temperature. Finally, piston cooling jets are added to cool down the piston by spraying oil at the lower position of the piston resulting in knock stability and fuel economy improvements. All of this results in up to a 2.2 percent increase in efficiency for optimized fuel economy, and an anticipated 29 city / 38 highway / 33 combined mpg (internal estimate for 6-A/T).
This 2.0-liter Nu four-cylinder engine is paired with Elantra’s latest generation six-speed automatic transmission. The new automatic transmission helps deliver dynamic performance with an overall 3.3 percent increase in efficiency for optimized fuel economy. A new valve body improves gear shift responsiveness and control, while an optimization in oil pump size aids in improving operating efficiency. A multi-clutch torque converter is also a new addition that allows more control over lock-up. Finally, rolling resistance and friction are minimized by adopting double angular ball bearings.
The engine features a multitude of friction-reducing and cooling components and high efficiency engineering features designed to enhance fuel economy and maximize performance. In addition, this Elantra is equipped with the new Drive Mode Select feature that adjusts both powertrain performance and steering effort, allowing the driver to customize the driving character by selecting from four modes: Smart, Eco, Normal or Sport, simply by touching a button on the center console.
Included is an unbeatable manufacturers 5-years warranty or 300,000 kilometers driven, which ever comes earlier.
