Hyundai has announced a new powertrain option for the Hyundai Sonata in the US market. Joining the existing normally-aspirated 185 hp, 241 Nm 2.4 litre Theta II GDI and 245 hp, 352 Nm 2.0 litre Theta II turbo offerings is a new 1.6 litre turbocharged four-cylinder engine that will be slotted into a new Eco variant.

The new 1.6 litre turbo Gamma engine produces 177 hp and 265 Nm of torque. What’s most interesting is that this engine will be mated to Hyundai’s first ever seven-speed dual clutch transmission in a production car. Hyundai claims the new downsized turbo engine and dual clutch transmission combo will allow the Sonata Eco a 10% improvement over the 2.4 litre Theta II GDI model.

In other markets, the Sonata is also available with a 2.0 litre GDI engine producing 165 hp and 201 Nm of torque. And of course, we’re expecting normally aspirated 2.0 and 2.4 litre non-GDI engine options for poor fuel quality markets such as Malaysia.

The new Sonata is slightly larger than the outgoing Sonata currently still on sale in Malaysia, being 35 mm longer and 30 mm wider, with improved cabin space as a result of the gains. Wheelbase is up by 10 mm, from 2,795 mm in the outgoing model to 2,805 mm on the new one.
