inline-4 cylinder engine, rated at 269 horsepower, paired to an 85-kilowatt (114-hp) electric motor.
In total, the system makes 398 hp and 472 pound-feet of torque; Land Rover says the SUV sprints from 0-60 mph in 6.4 seconds and features a top speed of 137 mph.
13.1-kilowatt-hour battery pack will power the Range Rover P400e for 30 miles on pure electric power.
By default, the plug-in hybrid SUV will operate in "parallel hybrid" mode, which combines gasoline and electric power—the system will determine when it's best to use only battery power or a combination of gasoline and battery power.
However, a "save" function built-in maintains a constant level of charge and ensures battery power is always available, should the driver want.
The function works via predictive energy optimization by factoring altitude data into a selected navigation route.
