Power for the top-tier S90 T8 comes from a supercharged and turbocharged, 2.0-liter, four-cylinder engine connected to an eight-speed automatic transmission.
With a fully charged battery ready to deliver up to 21 miles of all-electric driving range, the plug-in hybrid can deliver as much as 71 MPGe combined.
Driver-assistance features include a head-up display, automatic high beams, adaptive cruise control with steering support, collision-mitigation braking, blind-spot monitoring and cross-traffic alert.
