Portico is powered by Hyundai's new, high-tech Lambda V6 engine. It's a 24-valve, DOHC V6 with aluminum heads and cylinder block, mated to a six-speed Shiftronic automatic transmission soon to be offered in Hyundai's production vehicles. The Portico is also designed to accept Hyundai's hybrid drive system. This configuration features two electric motors; one driving the front wheels and a second driving the rear wheels, providing efficient AWD (all-wheel-drive) capability. Front power is supplied by a 110 kW (136 horsepower) electric motor; a 60 kW (83 horsepower) motor powers the rear wheels.
