Hyundai presented two hybrid concepts at the Geneva Auto Show, both based on the brand’s compact SUV platform.

Similar to Audi’s Q7 SUV, Hyundai will use a diesel engine to create its plug-in electric (PHEV) Tucson. The SUV will feature a 1.7-liter diesel paired with one electric motor and a seven-speed dual-clutch transmission. A 10.7 kilowatt-hour lithium-ion polymer battery gives the PHEV an all-electric range of 31 miles.

With 113.3 horsepower from the diesel engine and 67 from the electric motor, the plug-in has a combined output of 180 horsepower. Hyundai estimates the SUV’s CO2 emissions at less than 48 g/km.

Because the diesel engine powers the front wheels while the electric motor drives the rear, the Tucson PHEV will also offer the option of running in front-wheel drive, rear-wheel drive or all-wheel drive.

Hyundai also showed off its 48-volt Hybrid in Geneva, calling the setup as fuel efficient as a full hybrid for a fraction of the price.

This isn’t the same i40 48-volt hybrid that was on display in Paris last fall. The previous concept featured a smaller diesel engine and a 48-volt lead-carbon battery.

For the 48-volt hybrid shown in Geneva, Hyundai used a 2.0-liter diesel engine and a 10-kilowatt electric motor. Combined, the system generates 148 horsepower.

“Its 48-volt lithium-ion battery and 14 ps (13.8 horsepower) electric motor boost power by 10-percent and reduce emissions significantly while the 48V hybrid system costs just a quarter of a full hybrid solution to build,” said Hyundai.

These two hybrid concepts accompanied Hyundai’s launch of its next-generation Tucson. The all-new SUV now has sharper lines on the outside and “soft-touch” materials on the inside.

Consumers wanting a Tucson with an internal combustion engine can pick from four diesel engines (include a new, turbocharged 1.7-liter diesel) or a 1.6-liter gasoline engine.

A fuel cell Tucson is also currently available, though sales are still relatively low. Last December, Hyundai posted 12 sales for the hydrogen-powered SUV.

Hyundai hasn’t announced when (or if) these concepts will move to production. For customers that don’t want to wait, two other options will be available soon: Hyundai plans to release its new Sonata Hybrid and Sonata Plug-In Hybrid as 2016 models.
