Hyundai Motor is showcasing a range of innovative fuel efficiency and connectivity technologies at the 2015 Geneva Motor Show, among them a 48V Hybrid concept and a plug-in hybrid vehicle concept, both based on the all new Tucson platform.
The 48V Hybrid combines a 2.0-liter diesel model with 134 hp (100 kW) and a six-speed manual transmission along with a 14 hp (10 kW) electric motor; combined system performance is 148 hp (110 kW) and 413 N·m (305 lb-ft) of torque. This boosts system power by 10% while emitting only 109 g/km CO2. Compared to a full hybrid system, the 48V system delivers similar efficiency, for only a quarter of the cost.

Especially suited for application in larger cars and SUVs, the show car’s 48V Hybrid technology comprises a Hybrid Starter Generator (HSG), 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. The new hybrid system adds a modest 20 kg to the vehicle weight.
PHEV. Hyundai’s concept of a plug-in-hybrid vehicle (PHEV), also based on the All-New Tucson platform, is equipped with a 1.7-liter diesel engine and a seven-speed dual-clutch transmission, both available in the All-New Tucson line-up.
The engine generates 113 hp (85 kW) and is accompanied by a 67 hp (50 kW) electric motor and a 10.7 kWh lithium-ion polymer battery, which enables the car to drive in pure-electric mode for more than 50 km (31 miles). Combined system output is a maximum of 180 hp (135 kW) with 474 N·m (350 lb-ft) of torque. Hyundai engineers estimate co2 emissions of less than 48 g/km while the vehicle’s performance capabilities could be increased significantly.
The electric motor is placed at the rear of the car and drives the rear axle, while the diesel engine drives the front axle. This setup enables the car to switch between rear-wheel drive, front-wheel drive and all-wheel drive depending on the driving situation.
For greater driver engagement and choice, the PHEV concept is equipped with a 4-mode drive selection.
The ‘Auto’ mode operates all systems for highest fuel efficiency.
The ‘Zero Emission Vehicle’ (ZEV) mode uses only the electric motor if the battery charge level is sufficient.
In ‘4WD’ mode both engines operate to enable all-wheel drive functionality.
In ‘Sport’ the performance characteristics of both engine and motor are prioritized.
Innovative connectivity features. The Connectivity Cockpit Concept holds a collection of new advanced technologies including wearable devices, integration of car generated data, rear seat child care and 3D-gesture controls. These assets offer an insight to Hyundai’s new ways of thinking to provide customers with value beyond expectations, setting out ways that customers could control and interact with its vehicles in the future.
A wearable device such as a smartwatch, paired with the in-car-system, can monitor the driver’s status (heart rate and alertness), recommending rest periods to promote safe driving. It can also inform the driver about blind-spots, alert them to appropriate following distances and provide navigation-details.
Hyundai’s content connectivity feature provides a calendar ‘life-log’ of daily driving activities, delivering integrated information from vehicle, cloud, tablet, smartphone and wearable devices. It can display POI suggestions by ranking driver preferences, while also listing fuel stations near the user’s route.
The rear seat child care function uses innovative tablet features to monitor passengers and children via a mini-camera and the head unit screen on the center stack. The system also has tablet-based co-pilot/navigator controls, which allow a passenger to interact with vehicle infotainment and comfort features, such as air-conditioning, while the driver’s eyes remain on the road.
A fourth area of focus for the Geneva display is the company’s 3D hand-gesture controls, showcased in the Connectivity Cockpit Concept. The innovative system employs infrared and camera sensors to recognize driver’s hand commands to select navigation, infotainment, audio, air conditioning and even smartphone connectivity functions. While driving, only basic commands will be available, whereas when at standstill and neutral mode, the full range of functions will be accessible.

New Tucson. The production versions of the All-New Tucson will be available with a range of powertrains. These include two gasoline engines: 130 hp (97 kW) 1.6-litre GDI or 175 PS (1.6-litre T-GDI) - plus three diesel options: 115 PS (1.7-litre), 136 PS (2.0-litre standard power) or 173 hp (129 kW) 2.0-liter high power. The new turbocharged 1.6-liter T-GDI gasoline engine delivers maximum torque of 265 N·m (195 lb-ft) from 1,500 to 4,500 rpm and is offered with a six-speed manual or the seven-speed dual-clutch transmission (7DCT).
The 113 hp (85 kW) diesel engine delivers maximum torque of 280 N·m (207 lb-ft) from 1,250 to 2,500 rpm and is available exclusively with a six-speed manual transmission, 2WD and fuel-saving stop-start technology. The 2.0-liter turbo-diesel with a low inertia single-scroll turbocharger is offered in two versions: the standard power 134 hp (100 kW) delivering 373 N·m (275 lb-ft) of maximum torque at 1500 to 2500 rpm. The high power 183 hp ()137 kW) version delivers max torque of 402 N·m (297 lb-ft) from 1,750 to 2,750 rpm. Both feature maintenance-free lean NOx trap catalyst technology to reduce emissions.
The 1.6-liter T-GDI gasoline and 2.0-liter diesel engine can be mated with a 4WD-system, which delivers 100% of torque to the front wheels during normal road driving and up to 40% to the rear wheels, automatically, depending on conditions. A manually-selected ‘Lock Mode’ splits torque 50/50% for enhanced stability at low speeds.
All engines have been enhanced to offer improved driveability and fuel efficiency, as well as meeting Euro6 emission standards. Hyundai Motor’s Start-Stop system is available for selected engines.
The All-New Tucson is built on a completely new platform. The new chassis of the All-New Tucson has been developed for European customers with a focus on ride comfort without compromising driving dynamics. The new rack-mounted motor-driven power steering is precise and direct while the new suspension and dampers offer high levels of comfort and compliance for a smooth ride.
Hyundai Motor has developed every element of the chassis to enhance high-speed and cornering stability, while also maximizing the benefits of the long wheelbase (2670 mm) and wide track to optimize ride and handling characteristics for European roads and consumers.
A new electric motor-driven power steering (MDPS) system features newly developed software and a rack-mounted electric motor giving a fast and direct response.
The new Drive Mode Select (DMS) function on automatic transmission models offers customers a choice of two drive modes—Normal and Sport—with different characteristics for the steering, throttle, engine and gears.
