Hyundai has thrown two concepts based on the all-new Tucson, showcasing a range of fuel efficient technologies that we may see from them in the near future.
The first one is the Tucson 48V Hybrid Concept which demonstrates similar fuel-saving efficiency to a full hybrid at the quarter of the cost, according to Hyundai. Based on a 136ps 2-litre diesel six-speed manual model, the concept is offering 10% more power while emitting 109g/km of CO2 emissions thanks to a 14ps electric motor assisting the diesel unit. The 48V Hybrid Concept boasts a total output of 150ps and 413Nm (304 lb.ft) of torque.
The concept also benefits from a Hybrid Starter Generator (HSG) – an electric motor replacing the conventional starter – an inverter and a low voltage DC/DC converter. “The HSG supports the diesel engine with its additional output, enables the ISG to restart the engine with almost no noise or vibration and acts as a generator during deceleration, recharging the 48-volt lithium-ion battery” says Hyundai, adding that the new hybrid system adds a modest 20 kg to the vehicle weight.
The other concept shown is the Tucson Plug-In Hybrid Concept. The PHEV Tucson is equipped with a smaller, 1.7-litre diesel engine, coupled with the company’s all new 7-speed double clutch transmission. A more powerful 68PS electric motor, located at the rear of the car, drives the rear axle while the 115ps engine drives the front. The total torque delivery is an impressive 474Nm (350lb.ft) and Hyundai says that the estimated CO2 emissions are only 48g/km.
The Tucson PHEV features 4 driving modes, with one of them allowing the use of the electric motor only for a limited time. ‘4WD’ mode enables both engines all the time, ‘Sport’ mode prioritizes power over everything and ‘Auto’ is the mode for the highest fuel efficiency.
