The BMW ActiveHybrid3 is the hybrid version of the 3 Series body with four doors. t has a gasoline engine and an electric motor. The gasoline engine has six cylinders in line and three-liter engine is the same as used in the BMW 335i. Maximum power is 306 hp. The synchronous electric motor is rated at 55 hp. The combined maximum power is 340 hp. Traction is back and gearbox 8-speed automatic.
The electric motor is powered by the energy stored in a lithium-ion battery located under the boot floor. The latter volume is 90 liters less than the other 3 Series saloon, leaving a total volume of 390 liters. The backs of the rear seats fold down-optional-in 40:20:40 ratio. The hybrid system is a mass increase of 135 kg with respect to 335i.
The battery can accumulate enough energy to allow the electric motor to move the car for 4 miles at an average speed of 35 km / h without the help of the combustion engine. It is also possible to reach speeds up to 75 km / h using only electricity, obviously at this speed autonomy is less than 4 km.
There are several driving modes, inter alia, modifying the management of the internal combustion engine. During this deceleration can be decoupled and disconnect the drive shaft. With mode "ECO PRO" active this happens at speeds up to 160 km / h. In "Comfort" between 60 and 80 km / h and treading lightly on the brake. With modes "Sport" and "Sport +" no disconnection occurs.
Standard is a system that automatically switches off the combustion engine at idle phases, traffic lights, zebra crossings, stop, etc. -. A BMW calls it "Hybrid Auto Start Stop." Also there is another system from data provided by the browser mapping "Professional"-the most complete GPS optional available for this BMW is able to anticipate the actions of acceleration or braking to make the conductor according to the curves, speed limits, earrings, etc. - and prepare the propulsion system to be more efficient in energy use.
