The all-new BMW 330e iPerformance adds another highly innovative variant to the BMW 3 Series line-up with its advanced plug-in hybrid drive system. For the first time, cutting-edge BMW i technologies have been integrated into the world’s most successful premium model. The BMW 3 Series Sedan has already set standards for sports performance and fuel economy in its segment using conventional combustion engines. Key ingredients are its intelligent lightweight design, outstanding aerodynamics for its class and the extensive use of BMW EfficientDynamics technology fitted as standard. The all new BMW 330e iPerformance will be available in summer 2016 at dealers starting at $44,695 including Destination and Handling.
The combustion engine fitted in the BMW 330e iPerformance is based on the four-cylinder gasoline unit with BMW TwinPower Turbo technology that has already won the International Engine of the Year Award on two occasions. Stand-out characteristics include its sporty power delivery, output of 180 hp and peak torque of 215 lb-ft.
The electric motor, developing 87 hp with maximum peak torque of 184 lb-ft, and the power electronics are derived directly from the BMW eDrive technology featured as standard in the BMW i3 and BMW i8 models. The motor is powered by a lithium-ion battery with a capacity of 7.6 kWh (gross)/5.7 kWh (net). The model-specific concept of the high-voltage battery, including its battery management system and highly efficient direct cooling system derive from BMW i. The battery can be recharged at any domestic power socket and is mounted flat in a particularly crash-safe position underneath the load compartment. The power electronics form a single integrated system that drives the electric motor via a liquid-cooled inverter, manages the energy flow from the high-voltage battery to the on-board electrical systems and provides centralized control of hybrid-specific functions.
The BMW 330e iPerformance consequently offers a system output of 248 hp and peak torque of 310 lb-ft, allowing a sprint from 0 to 60 mph in 5.9 seconds and reach a top speed of 140 mph. Pure-electric driving is possible at speeds of up to 75 mph and with a range of around 14 miles. The electric boost function is permanently enabled. The electric motor supplements the power from the combustion engine with 74 lb-ft of torque and can deliver a brief extra boost– depending on the position of the accelerator – of up to 184 lb-ft.
The power generated by both the combustion engine and the electric motor is channelled to the BMW 330e iPerformance model’s rear wheels via an eight-speed Steptronic Sport Automatic transmission with shift paddles. The transmission ratios take effect for both drive systems, lowering the mechanical and thermal loads placed on the electric motor by sustained high revs. This has a positive effect on the operating life of the electric drive system. It also means a torque converter is not required, which partially cancels out the extra weight of the additional drive unit. Just like conventionally powered BMW models, the advanced Steptronic transmission’s low friction losses allow for additional contribution to the high efficiency of the car’s drive system.
