Hyundai Nuvis Concept

The Hyundai Nuvis concept (hybrid drivetrain) is destined for the next-generation Sonata...

As a parallel hybrid, the Nuvis can be driven in all-electric mode, gasoline-engine-only mode as well as any combination thereof. Engine management software automatically shuts off the gasoline engine when the Nuvis comes to a stop, improving overall fuel mileage and providing zero emissions, while Hyundai's Integrated Starter Generator (ISG) restarts the engine once pressure is applied to the accelerator pedal.

The Nuvis is notable for two reasons: First, its hybrid drive train will find its way into the next-generation Hyundai Sonata, and second, Hyundai says the concept's styling hints at what the Santa Fe's replacement could look like.

Hyundai's Hybrid Blue Drive architecture combines a 2.4-liter 4-cylinder (known as the Theta II) with a 30- kW electric motor, the last also producing 151 lb.-ft. of torque. The total estimated output of 228 bhp is put to the road via a 6-speed automatic transmission. Hyundai says the Nuvis's lithium polymer batteries, which are stored underneath the trunk floor, are more durable and space efficient than nickel-metal hydride and lithium- ion versions.
