Hyundai Elantra Coupe coming to the 2012 Chicago Auto Show

Article by Christian Andrei, on November 14, 2011

Hyundai is set to unveil an Elantra coupe this February at the Chicago Auto Show as it attempts to capitalize on the current sales momentum by strengthening its product line. Hyundai Motor America CEO John Krafcik had presented the Honda Civic-fighting car during an event located near Ann Arbor, Mich. Unfortunately, cameras weren’t allowed in.

A redone version of the Touring model, presently a small wagon, will be joining the Elantra coupe. The updated Elantra sedan has gotten strong reviews and sales to enhance its market presence in the crucial U.S. sector.

Through October, 160,922 Hyundai Elantras were sold in the U.S. This is 46% higher than sales during the same period in 2010. Krafcik said that the car had surpassed its expectations. Hyundai didn’t provide details about the coupe but its instrument-panel layout is similar to what’s used in the sedan. The back seat is spacious and it used high-quality materials.

The model is sportier and has different gear ratios. As part of a product blitz, Hyundai intends to launch a turbo Veloster, an Elantra Touring and coupe, a Santa Fe, an Azera and a Genesis coupe in 2012.

The redesigned Elantra Touring may be marketed as a 5-door hatchback. For now, the current car is available as a wagon. The 5-door hatchback will go on sale in the next summer and it will be built in Korea.

Engineers working on the new Hyundai Elantra Coupe wanted to ensure it could generate the same level of output you would expect from its sedan model and they beat it. With 148 horsepower and 131 lb-ft of torque to the sedan's 145 horsepower and 130 lb-ft of torque, the Coupe's 1.8 liter four cylinder engine is estimated to be something of a world champion in its class.

Pushing an easy 6% more horsepower than its closest rival the Civic Coupe, all this extra muscle is possible with the new advanced clean engine technology called Nu. Due to the properties of the engine, the majority of Elantra Coupes sold are in fact classed by the EPA as Partial Zero Emission Vehicles (PZEV).

With none of the complexity or cost of a hybrid electric vehicle, the PZEV Elantra Coupe is just as clean and has so far managed to surpass every environmental target it has been tasked with but this is just in the 'green states'.

Outside of this region, the Elantra Coupe is classed as an Ultra Low Emission Vehicle (ULEV). The Nu engine is not just better for the environment as it is also 30% lighter than your standard engine block and can easily provide the same equivalent strength despite being made from aluminum rather than iron. Other changes include the switching from aluminum to plastic for the two-stage Variable Intake System (VIS).

This modification has made it possible for the intake air to vary between the long and short intake manifolds, the results of which have provided a 30% drop in weight, 15% drop in cost, and a 4% improvement in performance when compared with the aluminum model.

D-CVVT or Dual Continuously Variable Valve Timing has been included to provide an increase in power for the hydraulic engine mounts and camshafts. These improvements have since gone on to provide a more efficient and refined engine. It was found when using D-CVVT on the camshafts that there were a number of refinements made to the original process.

Increased volumetric efficiency led to a 2% increase in performance, the reduction in pumping loss brought about a 2% improvement in fuel efficiency and a 30% drop in hydrocarbon emissions. Whereas in the valve-train, the introduction of the roller swing arms and the hydraulic lash adjusters have brought about an increase in fuel efficiency by 1% due to the reduction of friction in the valves.

The Nu engine has also gone some way to reduce the amount of noise, vibration and harshness (NVH) with the silent timing chain, which requires no additional maintenance once installed.
