Hyundai admits overstating 2015 Sonata mileage claims in publicity material

Added in: Hyundai

After inflating figures for 8 models from 2011-2013MY, and paying 343 USD to each owner of the 600,000 cars affected by the inflation of the figures, the Korean car maker is at it again! This time, Hyundai has acknowledged inflating mileage figures of the 2015 Sonata in publicity material given to the press.


Hyundai had said the all-new Sonata can return 29.6 mpg US (35.4 mpg UK or 7.9 liters / 100 km), but tests carried out by the government say it actually does 28.4 mpg US (34.1 mpg UK or 8.2 liters / 100 km).

Hyundai has specified that it wasn’t a deliberate mistake as they only wanted to point out the car’s six percent improved fuel economy despite the added weight of the Sonata. The bookings for the new Sonata have already commenced and the car will hit the showrooms in South Korea later this month, which implies the car will be unveiled soon.


In a statement issued today Hyundai said “we are very sorry for causing confusion to reporters” and admits it “may have a short-term impact on its reputation.”
