The car, before extra boost, is able to use both the ICE and electric motor. The extra boost gives it more than before. But in auto mode, the car is not just using 188 HP.

From Greencarcongress:

The plug-in hybrid system pools the abilities of a 2.0-liter four-cylinder gasoline engine with BMW TwinPower Turbo technology and output of 135 kW/184 hp with an electric motor which generates peak output of 83 kW/113 hp. Together, the two drive sources produce maximum system torque of 420 N·m (310 lb-ft).

A new feature—included as standard in the new BMW 330e Sedan—is XtraBoost. The driver can quickly bring XtraBoost into play by activating SPORT mode with the Driving Experience Control switch. A vigorous stamp on the accelerator unleashes an additional 30 kW/40 hp on top of the combined 185 kW/252 hp already generated by the combination of electric motor and combustion engine; XtraBoost keeps it on tap for up to 10 seconds.

The result is the signature powertrain character of the BMW 3 Series Sedan, comprising (for the first time in a hybrid model from BMW) incredibly sporty yet also precise accelerator response, and a specific shift program for the eight-speed Steptronic transmission including engine-braking downshifts.
