Even if it wasn't really necessary
The most striking detail changed on the V90 is the design of the new taillights. It now includes a LED signature for the sequential turn-light indicator. Other exterior changes include new light-alloy wheel designs and new colors for the bodywork.
Inside, Volvo installed two USB-C sockets for the rear seats, instead of the 12v outlets. Maybe this is a downside since most people are still using regular 12v type plugs. For the front occupants there is an option for a wireless charger for phones.
The SPA (Scalable Product Architecture) used for the V90 now allows the use of a Bowers & Wilkins audio system, which means that the vehicle will be like a concert hall on wheels. The same platform is responsible for the introduction of the mild-hybrid system with a 48v architecture.
Elsewhere in its model range, Volvo Cars is significantly expanding the number of its 48 volt mild-hybrid powertrain options, making these engine options available on every single Volvo model.
For the engine range, Volvo installed 4-cylinder diesel or gasoline units, all turbocharged. For diesel, the power ranges between 150 hp and 235 hp, while the gasoline engines offers between 190 hp and 310 hp. The top of the range is the plug-in hybrid model T8, which offers a total output of 390 hp and 640 Nm (472 lb-ft).
