Volvo XC90 T8 Twin Engine Plug-In Hybrid
Not all seven-seat beasts get seven miles per gallon.
A few years back, driving a hulking 400-horsepower SUV propelled mainly by a four-cylinder engine would have seemed about as likely as running into Kanye West at Kohl's. But the upcoming Volvo XC90 T8 Twin Engine plug-in hybrid — a luxury people-hauler that the Swedish automaker bills as the "world's first seven-seat plug-in" — will generate that, via a high-tech, thrifty powertrain. A supercharger augments the low end of the four-cylinder's rev range, allowing time for a turbocharger to build boost at the high end. Meanwhile, an 82-horsepower electric motor drives the rear. Charged overnight, its battery should propel this electric Viking ship up to 25 miles emission-free before the gas engine kicks in. You'll also be able to choose "power" mode to use the battery for sub-six-seconds-to-60 bursts instead. [59 MPGe; around 25-mile electric-only range; estimated price $60,000]
