- The i30 is powered by a range of small-displacement turbocharged petrol and diesel engines delivering a dynamic and efficient driving experience.
Choice of powertrains
The i30 is powered by a range of small-displacement turbocharged petrol and diesel engines delivering a dynamic and efficient driving experience. There are two petrol engines and one diesel engine, with the latter having two power outputs depending on model.
All engines are fitted as standard with the Integrated Stop and Go (ISG) system for increased efficiency. Customers can choose between the 1.4 T-GDi turbocharged four-cylinder engine with 140 PS, the 1.0 T-GDi turbocharged three-cylinder engine with 120 PS or the 1.6-litre CRDi turbocharged four-cylinder diesel engine with 110PS or 136PS (exclusive to Tourer). Mated to the engines is either the six-speed manual transmission (6MT) or Hyundai’s efficient and direct-responding seven-speed dual-clutch transmission (7DCT).
1.4 T-GDi – light, frugal and fun to drive
The 1,353 cc four-cylinder turbocharged petrol engine is significantly lighter than its predecessor, the Gamma 1.4-litre engine. The unit’s base weight has been reduced by 14 kg and it also boasts greater efficiency and power, delivering 140 PS and 242 Nm of torque with fuel consumption and CO2 emissions as low as 5.5 l/100 km* and 124 g/km*.
The engine incorporates a high-pressure single-scroll turbocharger integrated in the exhaust manifold to improve operational efficiency. The relocated and re-engineered turbo means throttle response time and low-end torque have improved. The design injects fuel directly inside the cylinder, improving combustion rates for better power and fuel efficiency.
The turbocharged 1.4-litre T-GDi petrol engine is offered with the 6MT or the 7DCT, which gives a choice of fully automatic operation or manual gear changes.
1.0 T-GDi – three-cylinder dynamism
The 1.0 T-GDi engine, developed by the Namyang Technical Centre in Korea in collaboration with the European Technical Centre in Germany, with 120 PS and 171 Nm provides a perfect combination of dynamism and efficiency with fuel consumption and CO2 starting from as low as 5.4 l/100 km* and 122 g/km*.
A turbocharger with an electronically-controlled waste-gate actuator improves fuel efficiency by lowering pumping losses as well as improving throttle response and low-end torque. The unit features a six-hole GDi injector, pressured to a higher-than-average 200 bar, securing a clean combustion and improving fuel economy and emissions.
To keep the engine unit as small as possible, the exhaust manifold is integrated in the cylinder head and can therefore be cooled efficiently using the cylinder head water-cooling system. These efforts result in faster warm-up of the catalyst and ultimately in improved real-world fuel consumption and emissions.
The 1.0 T-GDi is offered with the 6MT.
1.6 CRDi – strong and efficient
For customers looking for a diesel engine, the Hyundai i30 is offered with a 1.6-litre turbocharged four-cylinder unit. In i30 five-door, it produces 110 PS and maximum torque of 280 Nm, available with either the 6MT or 7DCT.
The i30 Tourer can also be specified with the 110 PS 1.6-litre 6MT diesel engine, but is available with higher power of 136 PS when paired with the 7DCT.
Low emissions performance
The i30 range is now equipped with Euro 6d Temp engines that comply with the latest EU regulations. Diesel engines have also gained further updates with advanced SCR (AdBlue®) engine technology.
To ensure the i30 range complies with the new emission standards, the T-GDi engine benefits from a Gasoline Particulate Filter (GPF) which is designed to control particulate emissions. CRDi diesel engines have also gained further advancements applying a Selective Catalytic Converter to further reduce NOx emissions.
The seven-speed Dual-Clutch Transmission
Hyundai Motor introduced its first seven-speed double-clutch transmission in 2015, combining the benefits of automated and manual transmissions. The 7DCT provides an improvement in fuel consumption and CO2 emissions of up to 20% compared to a conventional six-gear automated transmission, while acceleration performance could be increased by up to 10%.
The 7DCT consists of two dry clutches and an actuator for each clutch. Engine power is transferred independently into the odd and even gear train to always be ready to shift into the next gear without any torque interruption. For optimised responsiveness the electric motor-driven actuator is applied, while external dampers improve the noise, vibration and harshness during driving.
In combination with the 7-speed dual clutch transmission, the i30 offers two drive modes: normal and sport. In sport mode there is a different shift pattern holding gears longer before shifting, the steering provides a sporty feel and the throttle response is adapted.
Ride and handling
The i30 has been developed and tested in Europe performing accelerated durability tests and dynamic testing on the most demanding race track in the world, the famous Nürburgring Nordschleife, as well as undergoing rigorous public-road testing throughout Europe from the coldest winter testing conditions in Sweden to trailer testing in the Alps and hot weather testing in the south of Spain to ensure that the high expectations of European customers are met.
The development engineers have defined the characteristics of the i30; precise, natural and connected steering; agile, responsive and predictable handling; a dynamic ride without compromising comfort with good body control. Compared to its predecessor the motor-driven power steering is 10% more direct and the vehicle response is 15 milliseconds faster.
The chassis of the i30 family provides a dynamic and compliant driving experience with high levels of ride comfort. Contributing to this is the standard multi-link rear suspension for all versions, with a dual lower arm and performance-oriented shock absorbers.
Braking performance is optimised with 288 mm discs in the front allowing the driver to apply a strong braking force especially in hot wheel conditions.
N Line performance upgrades
For more sporty driving dynamics, the suspension and engine response have been enhanced for the i30 N Line models with the 1.4 T-GDi 140 PS engine. PS4 Michelin Performance tyres are fitted, to exploit the tuned driving performance, while new enlarged front brakes further enhance the i30 N Line’s sporty character.
Strong and lightweight body: 53% advanced high-strength steel
Hyundai Motor is the only car manufacturer to make its own steel for the production of its vehicles globally with great benefits for the latest i30, which features a strong and light body that enhances the dynamic performance and increases passenger safety.
The quantity of Advanced High Strength Steel has almost doubled over its predecessor to 53% while at the same time reducing the weight of the body-in-white by 28 kg and increasing rigidity by 22%. In production, the structural adhesives length has been increased to 112 m, improving stiffness while reducing weight.
