"Pricing is not yet available," Volvo said.
Available models will include the 250-horsepower Volvo S90 T5 FWD or front-wheel-drive model in Momentum and Inscription trims, along with the 316-hp T6 AWD or all-wheel-drive model.
A muted exterior color palette features nine choices, including Mussel Blue Metallic, Luminous Sand Metallic and Crystal White Pearl Metallic.
Four wheel choices include optional 21-inch bright alloy wheels.
There are five option packages.
They include a Bowers & Wilkins premium sound system and a climate package for cold-weather buyers. That package includes heated front and rear seats, a heated steering wheel and windshield.
A Vision package includes a blind-spot monitoring system and Visual Park Assist.
A Convenience package bundles Homelink, Park Assist Pilot, a 12-volt power outlet in the trunk and a power trunk lid.
A Momentum Plus package adds such items as adaptive LED headlights and Thor's hammer daytime running lights.
Edmunds says: Pricing on the S90 is expected to be announced shortly. Then it will be time to get serious about putting in your order for the new Volvo flagship sedan.
