Elantra GT for 2013 makes North American debut
• Roller swing arm and Hydraulic Lash Adjusters (HLA)
• Electronic throttle control
• Offset crankshaft
The Nu engine features an aluminum cylinder head, crank and block with a cast iron cylinder liner. 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 CVVT on both camshafts has several advantages when compared with using it just on the intake camshaft. With D-CVVT, there is a two percent improvement in performance (increased volumetric efficiency), two percent improvement in fuel economy (reduced pumping loss) 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 by one percent, compared with direct valve driving. The Nu engine also features a maintenance-free silent timing chain system to enhance durability and improve Noise Vibration and Harshness (NVH).
The application of a composite resin two-stage Variable Intake System (VIS) versus aluminum, enables switching between long and short intake manifolds, resulting in a four percent improvement in performance, a 15 percent reduction in cost and a 30 percent reduction in weight.
Another tool Hyundai engineers have incorporated into Elantra GT is an electronic throttle control. The electronic throttle control replaces the conventional cable and mechanical linkage with fast responding electronics. This system accurately controls air intake and engine torque, improving drivability, response and fuel economy.
The Nu four-cylinder engine also has an offset crankshaft design that reduces friction between the piston and cylinder wall for a one percent improvement in fuel economy.
ELANTRA GT VS. ITS RIVALS
The 2013 Elantra GT can be equipped with a six-speed manual (M6CF3-1) or automatic (A6GF1) transaxle with SHIFTRONIC manual control. Elantra GT’s six-speed manual transmission provides short, crisp shifts and further optimizes engine performance. These crisp shifts are courtesy of triple-cone synchronizers for first and second gears, double-cone for third gear and single-cone for fourth, fifth and sixth gears.
INTERIOR SPACE AND PRACTICALITY
Maximizing interior volume and delighting customers with various seating layouts are hallmarks of Hyundai engineering and translate into more cabin room, cargo space and versatility. The Elantra GT features seating layouts that can comfortably seat five people or accommodate four passengers, plus long items like golf clubs or snowboards. Fold down two seats, to seat three people and hold larger packages or fold all of the back seats to get CUV-sized cargo space. These options allow customers to discover that Elantra GT has more interior volume than Matrix, Mazda3, Ford Focus and VW Golf and even more cargo capacity than the Nissan Juke crossover, thanks to fold-flat rear seats and rear seat cushions than can flipped upward.
The Elantra GT includes a number of convenient, standard stowage and storage features, including a sunglasses holder, two front and two rear cupholders, door bottle holders, cooled glove compartment, central console storage, sliding armrest, front storage tray, front seatback pockets and a cargo area under-floor storage. The cargo area also has a 12-volt outlet for consumers who desire an outlet to plug in their portable electronic devices.
ELANTRA GT ARCHITECTURE
Elantra GT is fitted with a MacPherson strut front suspension, with coil springs and gas shock absorbers. The rear suspension is comprised of a light weight coupled torsion beam for enhanced steering stability and monotube shock absorbers. A 22 mm diameter front stabilizer bar helps reduce body roll when cornering. Elantra GT is tuned for added feel, responsiveness and control, while the Elantra sedan is tuned for comfort. Modifications to the GT include higher rear spring rates, a stiffer twist beam and Sachs dampers for improved body motion control. These changes create driving dynamics which are sporty and comfortable. In addition, two suspension packages were developed to optimize tuning for the two different tire sizes. The Elantra GT’s Style package offers a sportier suspension calibration that is optimized for its lower-profile P215/45R17 tire.
