The new BMW i3 94Ah, the motor propels the BMW i3 from zero to 62mph in just 7.3 seconds
The BMW i3 94Ah replaces the current 60Ah model and has a capacity of 33kWh thanks to the higher storage density of the lithium ion cells. The battery dimensions remain unchanged with more than a 50 per cent range increase in the standard NEDC cycle, this equals a range of 195 miles. The motor propels the BMW i3 from zero to 62mph in just 7.3 seconds (BEV) making the BMW i3 both the sportiest and most efficient electric vehicle in its segment.
The latest in innovative battery technology.
The high-voltage battery in the BMW i3 consists of eight modules (each with 12 individual cells), and its capacity has increased significantly without any changes in structure or exterior dimensions. By optimising the cell-internal packages with more electrolyte and adapting the active material, BMW has succeeded in increasing cell capacity to 94Ah and overall battery energy to 33kWh.
The lithium-ion cells used in the battery are particularly notable for their high energy density and impressive cycle life: they are designed to perform their energy storage function over the vehicle’s entire lifespan.
The coolant of the air conditioning system is responsible for cooling the high-voltage battery very effectively. An optional heating system can also be used to heat the battery to ensure the optimum operating temperature of 20°C before starting off. The battery has been designed to last for the car’s entire service life. Customers receive an 8-year or 100,000 mile warranty on the battery.
The electric drivetrain: Optimised performance delivery, more efficient drive.
The hybrid synchronous electric motor, developed and produced specially for use in the BMW i3, generates an output of 170hp and provides maximum torque of 250Nm from the moment the car pulls away.
Thanks to an average power consumption of 12.6kWh/100m (in the New European Driving Cycle (NEDC) for the BMW i3 and 11.3kWh/100km for the BMW i3 Range Extender, the efficiency of the motor plays a key role in optimising the car’s range to 195 miles. The BMW i3 is thus the most economical electrically powered car of its size and output class. With significant benefits available from low charging tariffs, the low cost per mile would equate to running a diesel engine and achieving 470.8mpg.
The emissions of the BMW i3 94Ah with Range Extender amounts to 12g/km, a 1g/km reduction in comparison to the previous model while the exclusively electrically powered BMW i3 produces zero emissions locally.
The power density of the electric motor, weighing around 50kg, sets a new benchmark for electric vehicles. But the new engine is about more than simply numbers: with its smooth running, minimal vibration and low noise levels, it offers a uniquely calm driving experience.
When it comes to the driving attributes of the i3, BMW engineers have achieved a perfect balance of vehicle weight, performance and range. In addition to this, the new model also benefits from improved efficiency and DC Rapid-charge as standard. AC charging is now multi-phase allowing charging of 3.7, 7.4 or 11 kW, this represents a 50 percent increase compared to the previous BMW i3 60Ah. This means the charging time for the BMW i3 (94Ah) is less than three hours, in spite of the significantly larger battery capacity. The new BMW i3 94Ah can also be charged at home using a standard three-pin plug or by specifying a BMW i Wallbox.
