The new Elantra projects confidence with sculpted body forms complemented by smoothly contoured lines that reveal the underlying inspiration of Hyundai designers. Inspired by the concept of dynamic precision, Elantra's architecture was a perfect platform for collaboration between Hyundai designers and engineers to blend advanced styling with functional aerodynamics.
From the front, the new Elantra is defined by Hyundai's signature hexagonal grille that projects a distinctive character when combined with its modern lighting signatures, including available HID headlights with Dynamic Bending Lights and unique vertical LED daytime running lights, which are firsts for Elantra. Elantra's sporty lower front fascia integrates functional front wheel air curtains, a component that is derived from the Sonata Hybrid that helps manage air flow from the front of the vehicle and around the wheels to minimize turbulence and wind resistance. In addition, underbody covers, an aerodynamic rear bumper bottom spoiler and rear decklid designed with an expanded trunk edge contribute to Elantra's 0.27 coefficient of drag.

For 2017, the new Elantra receives two all-new powertrains designed for improved fuel efficiency and everyday drivability performance. The standard engine available on the base SE and Limited trim is a 2.0-liter Nu MPI Atkinson four-cylinder engine producing a peak 147 horsepower at 6,200 rpm and 132 lb. ft. of torque at 4,500 rpm (estimated). 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 either a standard six-speed manual transmission (available only on the SE trim) or Elantra's next 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 second powertrain is an all-new 1.4-liter Kappa turbocharged GDI four-cylinder engine equipped on the Elantra Eco trim, available in Spring 2016. This engine produces 128 horsepower at 5,500 rpm and a robust 156 lb-ft. of torque at a low 1,400 ~ 3,700 rpm and will be mated to an EcoShift seven-speed dual-clutch transmission. The Eco trim is projected to achieve an unsurpassed estimated 35 mpg combined rating based on internal testing.
Other features of the 1.4L turbocharged GDI four-cylinder engine include an integrated cylinder head and exhaust manifold that improves fuel economy 5~7% at higher engine speeds. An optimized straight intake port increases tumble flow for fast combustion, suppressing knock tendency and improving fuel economy. The turbocharger is a single scroll design with an electric wastegate actuator. The optimized turbine and compressor employs a sophisticated scavenging strategy that improves low-end torque and response, while the electric wastegate actuator improves low-end torque and part-load fuel economy by reducing back pressure. Finally, the high pressure fuel injectors have six individually sized laser drilled holes to optimize the fuel spray pattern.
Both engines feature a multitude of friction-reducing and cooling components and high efficiency engineering features designed to enhance fuel economy and maximize performance. In addition, all Elantra trims are 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 three modes: Eco, Normal or Sport, simply by touching a button on the center console.
