More tech details on Hyundai’s new Ioniq rangePOSTED BY Nigel Andretti ON 08 January 2016
HYUNDAI’s has almost come clean on its all-new Ioniq hatch, releasing more images without giving the whole game away and some concrete tech figures.
The South Korean car-maker is still yet to show the car’s front end but has released some technical details of the model’s three electrified powertrains.
While a pure electric variant will be offered, only the hybrid versions are covered in the fourth release regarding the new range, which will be available as a petrol electric hybrid or plug-in equivalent.
Under its bonnet is a 1.6-litre GDi petrol engine which produces 77kW (103hp) and 147Nm, but thanks to its ultra-efficient Atkinson cycle manages a thermal efficiency of 40 per cent – the world’s most efficient according to Hyundai.
The engine was specially developed for hybrid applications and has specialist design features such as a 1:35 stroke-bore ratio and a separated cooling for the cylinder head and block.
Its power is combined with a 32kW/167Nm permanent magnet electric motor which draws power from lithium-ion battery for a combined output of 109kW and 314Nm.
Power is sent to the front wheels via a six-speed dual clutch automatic transmission, which has been “optimised” for its hybrid application, resulting in a transmission efficiency of 95.7 per cent, the company says.
More details have also emerged regarding the Ioniq’s structure, such as its part-aluminium construction which comprises the bonnet, bootlid, front cross member as well as some front and rear suspension components.
Where heavier steel had to be used, higher-strength grades were used to maintain stiffness and impact protection without adding unnecessary weight.
Locating the EV drivetrain battery low down in the chassis has resulted in a lower centre of gravity for improved handling and road-holding in corners.
Hyundai has not yet revealed performance figures such as acceleration and fuel economy, or any details regarding the third electric-only variant, but more information is almost certainly on its way in the immediate future.
The model will make its public debut at the Geneva motor show in March, following its first reveal in South Korea later this month.
