Outside of the green states, the Elantra is available in Ultra Low Emission Vehicle (ULEV) configurations. Hyundai's advanced 2.0-liter in-line four-cylinder engine powers Elantra. This sophisticated 16-valve powerplant employs an aluminum cylinder head that features dual overhead camshafts (DOHC) and Continuously Variable Valve Timing (CVVT). The combination helps give the engine a very broad power spread, coupled with high fuel efficiency and low emissions.
The CVVT unit is positioned on the exhaust camshaft and controls the intake valve timing by advancing and retarding the intake cam in relation to the exhaust cam. The CVVT system increases volumetric and thermodynamic efficiency, which helps the engine deliver improved performance at high rpm and increased torque at low rpm. With better cylinder charging, fuel economy is also increased. By optimizing valve overlap, NOx emissions are reduced due to the resulting Exhaust Gas Recirculation (EGR) effect.
The ULEV variation is rated at an estimated 138 horsepower at 6,000 rpm and 136 lb.-ft. of torque at 4,600 rpm. SULEV engines are available only with a four-speed automatic transmission, and are rated at an estimated 132 horsepower at 6,000 rpm and 133 lb.-ft. of torque at 4,600 rpm.
TWO TRANSMISSION CHOICES
Hyundai Elantra comes standard with a precise five-speed manual gearbox. A smooth four-speed automatic with a new gated console-mounted floor shifter is available as an option and includes an overdrive lock-up torque converter for higher fuel economy at freeway speeds.
SUSPENSION AND STEERING
Elantra's design team worked to solve the classic design tradeoffs between interior roominess, agility and driving comfort. On one hand, interior space and cargo room are critically important to a sedan in its class; on the other hand, secure, responsive handling and good road isolation are also priorities. The Elantra's ride quality improves upon that offered by Civic, Corolla, Focus and Cobalt. An advanced, motor-driven, engine-speed-sensing rack-and-pinion power steering ensures the new Elantra has a more agile driving feeling than the outgoing model, and key competitors.
Elantra delivers a comfortable ride and responsive handling thanks to a front MacPherson strut suspension with coil springs and gas shock absorbers, and multi-link suspension and twin-tube gas shock absorbers. A 23.0-mm diameter front stabilizer bar and 17.0 mm rear stabilizer bar, which is larger than its predecessor's by 5.0 mm, helps reduce body roll when cornering, and tunes the Elantra's at-the-limit handling for maximum predictability. To enhance stopping power, the front and rear brakes are larger than its predecessor's at 10.8 inches (275 mm) for the front and 10.3 inches (262 mm) for the rear.
The 2007 Elantra body stiffness is up 49 percent from the outgoing model and nine percent over Corolla. Significant increases in body stiffness levels allowed Hyundai engineers to deliver a dynamic package that left little to compromise during the shock and bushing tuning phases. The result is precise steering and handling and a well- controlled, yet comfortable ride. By improving body rigidity and applying an optimized door sealing strategy, Hyundai engineers successfully reduced road noise two decibels below a comparably equipped 2006 Honda Civic based on internal testing.
THREE TRIM LEVELS
Hyundai Elantra is available in three distinctive trim levels - GLS, SE and Limited.
ELANTRA GLS - THE PERFECT COMPACT CAR
In keeping with Hyundai's high-value approach to standard equipment, the Elantra GLS has a remarkable array of desirable features. The Elantra delivers standard safety technologies unsurpassed in its segment, with six airbags, ABS with EBD, 4-wheel disc brakes, active front head restraints, and adjustable head restraints for all seating positions. A partial list of other standard features includes: power windows, intermittent windshield wipers, multiple storage areas, 60/40 split fold-down rear seatback, tachometer, dual vanity mirrors, tinted windows, two 12-V outlets and tilt steering wheel.
