Hello, anyone know what the difference would be between
1.6 T-GDi GT-Line 148hp 48V DCT ISG 5 Dr
And
1.6 HDI HEV GT line.
Currently got the first one on order but wondering if the other would be better to drive? Hard to get test drives for both cars without travelling to 2 different dealerships

Mild Hybrid EV (MHEV)
Instead of replacing the 12 volt unit the 48 volt system works with the standard battery. It’s connected to a hybrid motor and an electric supercharger, and takes over duties from the 12 volt unit such as powering the air-conditioning, catalytic converter and engine fan and provides a small boost to the drive (for starting off and assisting under acceleration). The battery is charged by regenerative means and switching off the engine when decelerating and at standstill. The battery does not have enough power to drive the car itself so there’s no electric motor so should it be called a Hybrid at all as drive is not coming from two sources? To put things into context, an electric car typically has a 40kWh battery, PHEV 10kWh, HEV 1.6kWh and a 48v mild hybrid battery equates 0.44kWh. The advantages to the driver are slightly decreased emissions, slightly increased performance and as drive is not coming from two sources, the ability to pair this system to a manual gearbox. The advantage to the Manufacturer is they can put ‘Hybrid’ all over the car for a very small outlay. This is the basket a lot of manufacturers are putting their eggs in; 50 percent of all hybrids sold by 2025 are projected to be a mild hybrid.
Hybrid Electric Vehicle (HEV)
A HEV uses the combined efforts of an ICE (internal combustion engine) and a battery-powered electric motor to drive the vehicle. The work of driving the vehicle is shared between the two propulsion sources in the best way possible at any given time. For instance, the electric motor can give the vehicle a boost of power, perhaps while merging or climbing a hill, without burning additional fuel. The vehicle may also be able to drive for brief periods solely on electrical power, particularly at pulling away, when later joined by the engine. Power for the electric motor is created by a built-in generator and stored in an on-board battery. In a HEV all power is generated on board and does not require plugging-in.
That’s great, thank you.
Hyundai/Kia Hybrid engines in the Tuscon/Sportage:
48V Mild Hybrid
Save fuel and reduce emissions with the 0.44kW battery 48V mild hybrid system. It supports the combustion engine with additional torque during acceleration and when starting from a stop reducing load on the engine. The 48V Mild Hybrid system is teamed with the 1.6T Smartstream petrol engine with 150PS or the 180PS 7 speed DCT transmission with 4WD on selected trims.
The 48V mild hybrid is really there just to help emissons with silight benifit in fuel economy. The 0-60 and top speed remain the same as the petrol version and as the same 150bhp that can acheive upto an extra 1.5mpg over the petrol engine only, so no real benifits.
The isg gear box has a drive by wire (fly by wire system), whilst it retains the gearstick it has no cluctch (semi automatic)
Electrifying efficiency HEV 230
The hybrid is powered by the new 1.6-litre T Smartstream petrol engine and a 44.2 kW electric motor, with a 1.49 kWh lithium-ion polymer battery for a combined total output of 230PS.The HEV 230 is a proper Full Hybrid Electric Vehicle (FHEV), it has fully automatic DCT gearbox, it is by far more fuel effiecent than the 48V mild hybrid and can travel short distances on electrical power only. The 0-60 time is 7 seconds, 2.4 seconds quicker than its petrol nd 48V mild hybrid counter parts, overall a much more pleasing drive. Perhaps most importanyly, the HEV isn’t suffering from blocked PPF (similar to a DPF on a diesel) issues like the petrol and mild hybrid counterparts are, with Hyundai/Kia still trying to find a fix for. There a full thread on this on the Sportage thread and other forums.
At the time I drove noth the Tuscon petrol and 48V mild hybrid (same engine and hybrids in the Sportage as there the same company really) There was no difference in drive apart from the petrol version being fully manual transmission, they drove accelerated the same and I opted for the petrol only as the 48V mild hybrid was about £1,700 more in AP, which at only 1.5mgg extra I’d never recoup the difference over 3yrs and for once the salesman agreed. I wanted the HEV 230 but it wasn’t on the scheme with Hyundaiand the Sportage had not yet come on the scheme at the time I ordered.
