The four-door gran coupé combines its spaciousness and practicality and an autonomy even for long trips.
The BMW i4 is the first all-electric model from the BMW brand that emphasizes dynamic performance from the beginning. Two versions of the model are available, including the first BMW M with zero emissions. The BMW i4 M50, a high-performance model of the BMW M GmbH, uses an electric motor on the front axle and an even rear one, offering a total system power of 400 kW / 544 PS and top driving pleasure, while its autonomy reaches 510 km in the WLTP cycle. The BMW i4 eDrive40 combines a 250 kW / 340 PS electric motor with classic rear-wheel drive. Its maximum autonomy according to the WLTP standard is 590 km.
According to the current second phase of the BMW Group transformation in view of electric propulsion, the development of the BMW i4 was based from the beginning on a flexible vehicle architecture, aiming at a purely electric propulsion system. The ultra-thin high-voltage battery has a cell height of just 110 mm, is mounted low on the floor of the vehicle and has a fixed connection to an aluminum panel and the front axle subframe. With a center of gravity up to 53 mm lower than that of the BMW 3 Series Sedan, uniform weight distribution, a torsionally rigid and lightweight body, excellent aerodynamics (Cd: 0.24), and in addition a long wheelbase and wide tracks create the perfect recipe for the famous BMW capabilities and exceptional long-distance comfort.
The performance characteristics of electric motors are determined by their torque – immediately available from a standstill. If the driver requires high power for more than 10 seconds, the BMW i4 M50 activates the Sport Boost program, which releases the maximum power and torque of 795 Nm of the drive system. This allows the BMW M version to accelerate from 0 to 100 km / h in 3.9 seconds. The BMW i4 eDrive40 drive delivers a maximum torque of 430 Nm, for acceleration from 0 – 100 km / h in 5.7 seconds.
The 5th generation BMW eDrive technology also includes a high voltage battery with the latest battery cell technology. The barometric energy density of the lithium-ion battery is about 20% higher than that of the battery used in the current BMW i3. The total energy content of the high voltage battery is 83.9 kWh (net energy content: 80.7 kWh).
The new generation of the iDrive imaging and control system first installed in the BMW i4 extends driver-vehicle interaction to physical dialogue. It is based on the new BMW Operating System 8 and has been designed with a clear emphasis on the BMW Curved Display touch screen functionality and verbal communication with the extensively upgraded digital assistant – BMW Intelligent Personal Assistant. In this all-digital BMW Curved Display, the display screen section (12.3 ”) and the control screen (14.9”) are merged into one unit behind a glass sloping towards the driver.
The suggested retail price of the new BMW i4 starts at € 54,850 for the eDrive40 version (the introductory version also receives a state subsidy through the “I Move Electric” program, which significantly reduces the original price of the car). Respectively, the proposed retail price of the M50 version starts from € 69,750 (including VAT).
