Hyundai today introduced a new sport coupe variant to its industry-leading Elantra line-up at the 2012 Chicago Auto Show. This two-door coupe model of the Elantra sedan, available this spring, will attract even more buyers to the Elantra line-up, further expanding its appeal to savvy consumers. It offers many of the same attributes that made the sedan version a sales success, while broadening its market reach to youthful, sporty buyers willing to forgo four-door versatility for coupe design appeal. The 2013 Elantra Coupe marks the continuing evolution of Hyundai’s “Fluidic Sculpture” design theme with sporty design language, while assuming a compact coupe segment leadership position with an eco-efficient powertrain, generous convenience features, exceptional roominess and abundant safety features.

Elantra Coupe is the latest vehicle in Hyundai’s 7/11 product initiative (seven new models in the next eleven months), following the Azera and Genesis Coupe. The 2013 Elantra Coupe represents a modern approach to the sporty coupe segment, using youth-oriented design and premium features offered with Hyundai’s strong value proposition. The 2013 Elantra Coupe poses intriguing questions: Why can’t a sporty coupe combine generous interior space with sleek design? Why pay premium coupe prices to get advanced safety and technology features? Why can’t a fun-to-drive sporty coupe offer 40-mpg fuel economy?
“FLUIDIC SCULPTURE” DESIGN LANGUAGE
Elantra Coupe takes Hyundai’s dynamic “Fluidic Sculpture” design principles to the next level. “Fluidic Sculpture” design language replicates the interaction of wind with rigid surfaces to create a perception of fluid in motion. Hyundai’s signature hexagonal front fascia opening and jeweled swept-back headlights give Elantra Coupe a lean, aggressive demeanor. Fog lights and available side mirror repeater lamps complement the view from the front.
From the side, Elantra Coupe conveys a wedge-like sport coupe silhouette with deeply sculpted surfaces. SE model sporty five-spoke 17-inch alloy wheels with dark spoke inserts add a dynamic presence, while fast A- and C-pillar angles frame a sharply tapered greenhouse, further accentuating the wedge profile. Just below the belt line, a prominent character line carries from the door through to the rear deck. Wheel arch creases give a subtle flared appearance around front and rear wheels, for a wide and aggressive presence. Further, a beveled rocker panel rounds out the lean and muscular effect.
From the rear, a blacked-out rear diffuser valance contrasts with dual chrome-tipped exhaust tips, and the SE model deck lid incorporates a lip spoiler design element. These sculpted surfaces serve to create a highly aerodynamic body. The drag coefficient for the Elantra Coupe is an exceptionally low 0.28 Cd, resulting in minimal cabin noise intrusion and optimal fuel economy. Elantra Coupe was designed at Hyundai's North American Design Center in Irvine, Calif.
Under the hood, the Elantra Coupe is powered by the same 1.8-liter Nu four-cylinder engine with 148 horsepower (estimated) and 131 lb-ft of torque (estimated) found in the Elantra sedan (145 horsepower and 130 lb-ft of torque for Elantra Coupe PZEV). This high power-density 4-cylinder puts out a full six percent more horsepower than the Civic Coupe 1.8-liter. Thanks to advanced clean engine technology, most Elantra Coupes sold in California, Oregon and several Northeast states are certified as Partial Zero Emission Vehicles (PZEV) by the EPA. The PZEV Elantra Coupe is as clean as many hybrid electric vehicles, without the extra technological complexity and cost. The PZEV Elantra Coupe helps Hyundai meet and exceed its environmental requirements. Outside of these “green” states, the Elantra Coupe is available as an Ultra Low Emission Vehicle (ULEV).
- Elantra Coupe 1.8-liter Dual CVVT (Nu Engine Family)
- Key Engine Components
- Aluminum block and head
- Dual Continuously Variable Valve Timing (D-CVVT)
- Variable Induction System (VIS)
- Roller swing arm and Hydraulic Lash Adjusters (HLA)
- Electronic throttle control
- Offset crankshaft
The Nu engine features an aluminum block with a cast-iron cylinder liner, cylinder head and crank. This unique configuration results in a block that is 30 percent lighter than an iron block, shedding more than 74 pounds of engine mass, while still providing equivalent strength. The 1.8-liter Nu also offers Dual Continuously Variable Valve Timing (D-CVVT) camshafts and hydraulic engine mounts for optimum power, efficiency and refinement. Using D-CVVT on both camshafts has several advantages when compared with using it just on the intake camshaft. These advantages include a two-percent improvement in performance (via increased volumetric efficiency), two-percent improvement in fuel economy (via reduced pumping losses) and a 30 percent reduction in hydrocarbon emissions. In the valvetrain, roller swing arms and hydraulic lash adjusters reduce valve-driven friction to improve fuel economy one percent compared with direct valve tappets. The Nu engine also features a maintenance-free silent timing chain to enhance durability and reduce noise, vibration and harshness (NVH).
A plastic two-stage Variable Intake System (VIS) enables intake air to be directed between long and short intake manifolds, resulting in a broad, linear power band. This results in a four-percent improvement in performance, a 15 percent reduction in cost and 30 percent reduction in weight, when compared with aluminum. Another technology Hyundai engineers have incorporated into the Elantra Coupe is an electronic throttle control. Electronic throttle control replaces the conventional cable and mechanical linkage with instantaneous computerized control. This system accurately controls air intake and engine torque, improving drivability, response and fuel economy. To further improve fuel economy, Elantra Coupe applies double-pipe plumbing technology to the internal heat exchanger. Double-pipe plumbing improves cabin cooling efficiency, while minimizing compressor size, reducing fuel consumption. In addition, an externally-controlled variable compressor is used to improve fuel efficiency when compared with an internal variable compressor.
The Nu four-cylinder engine also has an offset crankshaft design that reduces friction and pressure between the piston and cylinder wall for a one-percent improvement in fuel economy. Elantra Coupe’s fuel economy is estimated at 29 mpg city, 40 mpg highway for the six-speed manual transmission, and 28 mpg city, 39 mpg highway for the six-speed automatic transmission. These ratings give Elantra Coupe a highway-only driving range of up to 500 miles.
