article imageHyundai errs on 2015 Sonata mileage

Seoul - Hyundai is apparently out of the loop again when it comes to effectively reporting fuel economy ratings, this time reporting an error in the fuel economy figures of the new 2015 Sonata mid-size sedan.
Hyundai was investigated in 2012 by the U.S. Environmental Protection Agency (EPA) for being overly optimistic in the fuel economy ratings of its 2012 Elantra compact sedan, which was introduced at the 2010 LA Auto Show with much fanfare about its 40 mpg highway mileage (5.9 liters per 100 km). However, early buyers complained to the EPA about their cars’ mileage coming nowhere near the rated figure and in an audit of the Elantra mileage ratings, the EPA found a discrepancy of between one to six mpg and forced Hyundai to amend its window stickers and reimburse some 900,000 buyers for the difference in their fuel consumption — a cost of about $400 million, the company estimated.
In addition to Elantra, the EPA mandate also applied to Hyundai Accent, Azera, Genesis, Santa Fe, Sonata Hybrid, Tucson and Veloster models, as well as Kia Optima Hybrid, Rio, Sorrento, Soul and Sportage. Hyundai, which owns Kia, blamed the error on procedural differences between its testing and that of the EPA — manufacturers test their own vehicles and submit the figures to the EPA, which then audits about 15% of new models to ensure conformity.
This time around, Hyundai blamed the error on testing at its proving grounds that differed from government testing. Prior to launching the new Sonata in its home market, Hyundai released publicity materials to the media March 4, 2014 that claimed a range of 12.6 km per liter of fuel (7.9 liters per 100 km). The figure was amended to 12.1 km per liter (8.3 L/100km) in a Hyundai release to quickly address the error prior to the car’s going on sale.
A reported 10,000 cars had be ordered ahead of its March 24, 2014 public launch but Hyundai did not give details of what, if any, restitution might be offered to buyers who pre-ordered the new mid-sized sedan.
Sporting a more classic exterior than its predecessor, the 2015 Sonata is destined for a North America unveiling at the 2014 New York International Auto Show in April and is due in showrooms later in 2014.
