For the 2017 model year (the first model year) a short and long wheelbase sedan as well as an estate model were made available. For 2017, the short wheelbase model was sold in North America and Europe, the long wheelbase model was primarily sold in China. Volvo has hinted at possible coupe variants, but not until at least 2020. Beginning with the 2018 model year, the short wheelbase sedan was discontinued, and only the long wheelbase version of the sedan is sold across all markets.
Before its reveal, the first official pictures of the S90 were revealed on Wednesday, 2 December 2015. The S90 was unveiled to the public in January 2016, at the North American International Auto Show in Detroit, Michigan. The S90's design was well received, winning the Production Car Design of the Year award for 2015.
While not a direct successor to the second generation S80, the S90 replaces it as the flagship sedan in Volvo's lineup. Several trim levels are available, ranging from Momentum to Inscription. In July 2016 an optional, cosmetic R-Design package was announced. A long wheelbase version was announced and is available in the United States.
For the 2017 model year, a special stretched version of the S90 was made in China, primarily for that market. It is stretched by 12 cm (4.7 in) behind the b pillar. This initial chinese variant was not badged as "S90L".
For the 2018 model year, this long wheelbase S90 was introduced in the United States and Europe (the short wheelbase S90 was discontinued).
The S90 is only available with 2.0 litre, four cylinder petrol and diesel engines from the VEA family (DRIVe). The more powerful petrol engines are compound charged, as is the plug-in hybrid variant called the T8. The D5 diesel engine features Volvo's newPowerPulse technology that is designed to eliminate turbo lag, as well as an i Art injection system.
