Volvo spokesman Jim Nichols confirmed the timing for the V90 in the U.S., but said pricing has not been determined.
Volvo has not released U.S. technical specifications for the V90.
The V90, which replaces the Volvo V70, is designed to lure shoppers away from popular crossovers and SUVs.
Volvo is leaning on its wagon heritage as it launches the V90, touting the "ultimately practical nature" of the vehicle.
"While the Volvo brand today stands for more than estates, we are proud to carry forward this rich heritage with the V90," said Volvo CEO Hakan Samuelsson, in a statement on Thursday.
Wagons are called "estates" in Europe.
The V90 will feature Volvo's Pilot Assist semi-autonomous drive technology and a standard safety package that includes Large Animal Detection and Run-off Road Mitigation.
Connectivity is an important part of the equation with the V90, which includes smartphone integration with Apple CarPlay.
The V90's plug-in hybrid will deliver around 410 horsepower and have an electric-only range of around 31 miles, the company said.
Edmunds says: Car shoppers making long-range plans may want to consider the highly anticipated 2018 Volvo V90, although there are lots of good wagon, crossover and SUV options out there in the meantime.
