Volvo will unveil its new S90 premium sedan at the Detroit auto show (NAIAS) in January. One of the powertrain options will be a T8 Twin Engine plug-in hybrid. Thus, the S90 will be the second Volvo to offer a plug-in powertrain using the SPA modular chassis system (the XC90 T8 Twin Engine PHEV went on sale in the US in August).
The S90 T8 uses essentially the same powertrain as the XC90: a T6 2.0-liter gas engine, an 8-speed automatic transmission, a crankshaft-mounted Integrated Starter-Generator (C-ISG), a 65 kW Electric Rear Axle Drive (ERAD), and a 9.2 kWh (6.7 kWh usable) Li-ion battery pack.
The ERAD propels the S90 in electric mode, provides extra torque during acceleration and performs brake energy recuperation. The C-ISG charges the battery, starts the legacy engine, and can provide electric boost power.
“With the launch of the XC90 we made a clear statement of intent,” said Håkan Samuelsson, President & CEO, Volvo Car Group. “We are now clearly and firmly in the game. With $11 billion of investment over the past five years, we have not only reimagined what Volvo Cars can be, we are now delivering on our promise of a resurgent and relevant Volvo Cars brand.”
