From Hyundai press:
Hyundai today introduced another exciting model, its all-new 2011 Elantra at the Los Angeles Auto Show. This marks the world debut of the latest version of the popular compact sedan. The 2011 Elantra encompasses Hyundai’s latest ambitions including “Fluidic Sculpture” design, advanced safety and fuel efficiency. In the very competitive compact car segment the Elantra continues to be on a fast four year lifecycle.
Elantra exemplifies Hyundai’s emotional “Fluidic Sculpture” design principles. “Fluidic Sculpture” considers the interplay of wind with rigid surfaces to create the illusion of constant motion. Elantra is an evolution of the design qualities found in Sonata. Successful sedans in the U.S. market all have a distinct silhouette and Day Light Opening (DLO – a designer's term for the side glass) and Elantra is no different.
Along Elantra’s sides are Sonata’s flowing lines, with the addition of a strong undercut feature line starting at the front door. These lines, along with muscular wheel arches and a sleek roofline, create a memorable and spacious package. Flowing lines also lead to an aerodynamic body. The drag coefficient for the Elantra is an exceptionally low 0.28 that compares favorably to the Chevrolet Volt (0.29).
Hyundai’s signature hexagonal front grille and detailed swept-back headlights give Elantra a compact athletic face. The assertive stance is complimented by 15-, 16- or 17-inch alloy wheels and athletic proportions. Available fog lights and side repeater mirrors complete the distinct design. Elantra was designed at Hyundai's North American Design Center in Irvine, Calif. Elantra’s fuel economy is 29 mpg city and 40 mpg highway, with the six-speed automatic transmission or manual transmission. These figures give Elantra a highway-only driving range of up to 500 miles.
Under the hood, the Elantra is powered by an all-new 1.8-liter Nu four-cylinder engine with 148 horsepower and 131 lb-ft of torque (145 horsepower and 130 lb-ft of torque for Elantra PZEV). The Nu engine was developed to replace the 2.0-liter Beta engine from the previous generation Elantra. The Nu is smaller in size, weighs 74 pounds less and helps achieve an 18-percent improvement in highway fuel economy, when compared with its predecessor.
Thanks to advanced clean engine technology, most Elantras sold in California, Oregon and several Northeast states are certified as Partial Zero Emission Vehicles (PZEV) by the EPA. The PZEV Elantra is as clean as many hybrid electric vehicles. The PZEV Elantra helps Hyundai meet its environmental commitments. Outside of these “green” states, the Elantra is available as an Ultra Low Emission Vehicle (ULEV).
