The new TUCSON Mild Hybrid*

Tucson is also available with 48V hybrid engines that limit fuel consumption and CO2 emissions. This system reduces fuel consumption and CO2 emissions by up to 11% (in the correlated NEDC cycle) according to vehicle specifications. Available in combination with the 1.6 CRDi 115 hp and 1.6 CRDi 136 hp engines, the 48V hybrid system provides an additional 12 kW of power to the combustion engine during start - up and acceleration phases.

*Available in Executive and Executive Plus models only

Key Points

Comfortable start and take-off

Comfortable start and take-off

The 48V hybrid system has a certain advantage in city traffic thanks to the light hybridization alternator-starter that supports the heat engine during the restart phases after being stopped in traf fic. This action ensures a fast and smooth engine restart with additional torque, taking advantage of the 48V battery power. The light hybridization alternator - starter assists the engine during acceleration phases by compensating for torque and power.
Efficient and boosted acceleration

Efficient and boosted acceleration

During acceleration, the light hybridized alternator starter supports the heat engine with a compensatory power of 4 to 12 kW, depending on the battery charge level and the amount of driver - initiated acceleration . As soon as the desired speed is reached, the 48V hybrid system switches to neutral mode, providing no power. As a result, CO2 emissions and fuel consumption can be reduced by up to 11% (NEDC correlated cycle)
Constant driving

Constant driving

At a constant speed, the light hybridization alternator / starter is either inactive or acts as a generator to recharge the 48V battery according to its charge level.
Energy recovery

Energy recovery

During braking phases, the rotating crankshaft supplies the light hybridization starter - alternator, which then acts as a generator with a maximum energy recovery of the order of 10 to 12 kW. The generator converts the kinetic energy of braking into electri city supplying the 48V battery. In these phases, the heat engine remains running to allow the transmission of power up to the light hybridization alternator - starter.
Extended start - stop

Extended start - stop

When coasting at low speeds, the start - stop function already activates at 30 km/h. Under deceleration between 30 and 0 km/h, and with the clutch disengaged, the engine is switched off completely
