Hyundai Grandeur engines
The Hyundai Grandeur is a South Korean 4-door business-class sedan from the Hyundai Motor Company. Began to be manufactured in 1986. Currently, since 2011, the fifth generation of the model is being produced. In 2017, the car was updated. However, official car sales in Russia have stopped since 2011 due to a decrease in demand. The translation of the model name from English means “grandeur”. Grandeur is available in three trim levels – Business, Elegance and Premium.
The Hyundai Grandeur was offered with 24 engines since 1986 (2 diesel, 22 petrol). Displacement ranges from 2.0 to 3.8 liters, power output from 95 to 300 hp. 15 use a timing chain and 10 a timing belt. 2 are turbocharged. The longest rated lifespan belongs to the Hyundai-Kia D4HB (about 450,000 km).
