Well established. And future-ready.

From humble beginnings, the technology behind internal combustion engines has developed at an exponential pace, toward more power and torque, but also toward greater efficiency and emission reduction. Hyundai has evolved as a global leader in all of those areas.

What is the difference?

Diesel engines work by compressing the air inside the cylinder. This increases the air temperature enough to ignite the atomised diesel fuel injected into the combustion chamber. Petrol engines use spark plugs to ignite the air-fuel mixture.

    From the 1 litre, 3-cylinder multi-point fuel injection petrol engine with 67 PS in the new i10, to the 2.0 T-GDI engine with 280 PS in the new i30 N - Petrol engines are available across the majority of the Hyundai Line-up, including Hybrid and plug-in Hybrid variants. This variety ensures petrol engines remain an efficient, convenient choice for most consumers.

    Hyundai diesel engines.

    The fuel economy of Hyundai diesel engines (especially with the 48 V mild hybrid option) means they are a good choice for you if you drive a high annual mileage or cover a lot of miles on the motorway. Or if you require the higher torque of a diesel in your activities.

Modern engine technology: Smartstream.

'Smart’ technological objectives of saving fuel, improving performance, and reducing gas emissions were applied to every step of the ‘Stream’ when Hyundai engineers developed our latest powertrain technology: the stream of air and fuel injected in the engine, and its explosive power delivered to the wheels via the transmission.

    Continuously Variable Valve Duration (CVVD).

    CVVD optimises both engine performance and fuel efficiency. The valve control technology regulates the duration of valve opening and closing according to driving conditions, achieving a 4% boost in performance and a 5% improvement in fuel efficiency. All this, while cutting emissions by 12%.

    Dual-Port Fuel Injection (DPFI).

    DPFI uses two injectors for each intake port to better maintain the stable air/fuel ratio in the mixer, which also improves the Exhaust Gas Recirculation (EGR) ratio, benefitting the engine's fuel economy. By atomising fuel droplets, DPFI also reduces the emission of harmful particulate matter.

    Integrated Thermal Management System (ITMS).

    ITMS regulates engine temperature while also controlling the vehicle’s heating and air conditioning. A 3-way valve placed next to the engine regulates the flow of engine coolant to the radiator, transmission oil warmer and heater. The valve can not just open and shut but also control the amount of coolant flow setting the overall coolant flow pattern that bests suits the engine’s status.

Smart transmission technologies.

In internal combustion engine vehicles, transmissions serve the important role of situationally adjusting the engine RPM to allow controlled application of power. Appropriate shifting of gears lets the engine continuously function at high efficiency, improving both performance and fuel economy.

8-speed wet Dual-Clutch Transmission (DCT).

Dual-Clutch Transmissions (DCT) combine the advantages of manual transmission and automatic transmission. Their fast shifting and highly efficient power delivery combines the convenience of automatic with the fuel efficiency of manual transmissions. Wet DCTs use oil to cool the clutches, withstanding the higher torques of our most powerful engines.

48V mild hybrid.

The 48V mild hybrid powertrain system supports the combustion engine, adding electric power during the different stages of driving. Find out more about this innovative fuel-saving system.
  1. Illustration of the Hyundai TUCSON showing the start of 48V mild hybrid system.

    Comfort Start.

    The mild hybrid system is particularly useful in city traffic, with the Mild Hybrid Starter Generator (MHSG) supporting the combustion engine when re-starting after traffic stops. It supports a faster and smoother engine start with supplemental torque, drawing on energy from the 48V battery.

    Acceleration.

    Under acceleration, the starter generator supports the engine with 4 to 10 kW of power, depending on the battery system’s charge and the driver's accelerator input. Once the required speed is reached, the system shifts to neutral mode, delivering no power. As a result, CO2 emissions and fuel consumption can be reduced.

    Charging while driving.

    At a constant speed, the system either is at idle or acts as a generator charging the 48V battery, depending on the battery state of charge.

    Recuperation.

    In active braking or overrun phases, the rotating crankshaft powers the starter generator, which then recuperates a maximum output of 10 to 12 kW. The generator converts the kinetic braking energy into electricity and feeds it back into the 48V battery.

    Start-stop and coasting.

    When coasting at low speeds, the start-stop function activates at 30 km/h. At speeds between 30 and 0 km/h, and with the clutch disengaged, the engine switches off completely.

Intelligent Manual Transmission (iMT).

Designed specifically for mild hybrid engines, the iMT increases fuel efficiency by automatically engaging coasting mode whenever you release the accelerator.
