the original BMW i4.
Together, the BMW i4 and BMW iX represent the next significant development in the BMW Group’s journey toward a 50% market share for sales of completely electric vehicles by 2030. So it seems sense that both vehicles are taking off at the same moment. Details on the first-ever BMW i4 can be found here. Regarding the BMW
Along with its high-voltage battery and a motor system that uses an incredibly efficient heat pump function, the BMW i4 comes standard with an integrated heating and cooling system for the cabin. The system has a shared expansion tank and three cooling/heating circuits that can be connected through electric valves. The drive units’ excess heat is used to reheat the high-voltage battery when the vehicle is moving in cold weather. When compared to the system in the existing BMW i3, the highly integrated version of the heat pump developed by BMW uses up to 75% less energy. In any operating state and in all typical weather conditions, a two-level cooling module, a refrigerant compressor, two evaporators, a water-cooled condenser, and a high-performance control unit work together to ensure optimal temperature control for both the interior of the vehicle and the BMW eDrive components. A pair of potent continuous-flow heaters with 9 kW of heating output each help the heat pump when the surrounding temperature is exceptionally low. This guarantees that thermal comfort on par with BMW models powered by traditional methods may be delivered extremely effectively in any circumstance. The most recent model of the heat pump uses waste heat from the motors, ambient heat, heat from dehumidification, and other heat sources for energy-efficient operation.
The integrated heating and cooling system also ensures that the high-voltage battery will be kept at the ideal temperature during quick charging from a DC charging station and highly dynamic driving conditions with high power demand. Anticipatory thermal management will automatically pre-condition the battery before a stop at a fast-charging station if the navigation system’s route guidance function is turned on and has scheduled one for the BMW i4. When the high-voltage battery arrives at the charging station, warming it up or cooling it down as necessary will ensure that it is at the ideal temperature for speedy and effective charging at maximum capacity. The current battery temperature, remaining range, expected charging rate, and the quantity of electricity required to be fed to the battery in accordance with the calculated total route are all taken into consideration by thermal management.

Both models share a single 83.9 kWh battery pack with an 81.5 kWh usable net capacity, and they can both be charged at up to 200 kW. The i4 M50 has a lower range, which is most likely due to its increased weight and somewhat worse coefficient of drag, which may be brought on by its unique front bumper and wheel designs. In comparison to a 2020 MY i3, the battery pack of the i4 has a 40% higher energy density, according to BMW.
Additionally, the i4 receives a heat pump that, according to BMW, uses up to 75% less energy than the i3 of the same model year. The producer also says

The inside of the i4 will be updated and somewhat modified from that of the current 4 Series. The i4 comes with BMW’s new iDrive 8, which is presented on a massive 14.9-inch central display and a 12.3-inch driver’s display. The significant news is screen-related; the dashboard itself is mostly unaltered.
BMW has teamed with EVgo in the US in order to provide access to approximately 38,000 Level 2 chargers around the nation. BMW is conscious that the charging infrastructure available outside of Tesla’s Supercharger network is not the greatest. Every new i4 that is purchased or leased will include a $100 EVgo charging credit.
Other notable BMW i4 features include an automatic climate control system with an integrated nanofiber filter, the assurance of exceptionally low cabin noise levels (due to the use of acoustic glass), programmable mood lighting, BMW IconicSounds Electric (the EV sound signature that the manufacturer had a well-known composer create), an enhanced voice assistant, BMW ID, over-the-air updates, and wireless smartphone integration.
The BMW i4 will appeal to buyers who value modern on-board technologies and good build quality.

The biggest giveaway that the i4 lacks a combustion engine beneath the hood is the kidney grille, which is walled off like the 4 Series Gran Coupe. The i4’s large grille has drawn some criticism, but its overall appearance is still classy and refined, and its five-door body shape gives it a noticeable presence on the road.
A brief glance inside the i4 cabin will reassure you that BMW hasn’t compromised on build quality; it’s generally immaculate, with plenty of soft-touch materials in use, as well as brushed metal and carbon-fibre-effect accents. The twin digital panels are distinctive and form a curved display. BMW also features its most recent iDrive operating system.
The base xDrive40 Sport variant comes with a reversing camera, sports seats, a choice of 17- or 18-inch alloy wheels, LED headlights, and a heat pump that aids the electric motor’s efficiency. However, it will be challenging to resist the allure of the (mainly cosmetic) enhancements that come with the fashionable M Sport trim for an additional PS1,500.
The i4 Can Boogie, sir.
The i4 uses a low center of gravity by slinging its battery pack beneath the floor instead of using a “skateboard” platform like the iX or the Tesla 3. Utilizing this characteristic, an adjustable suspension offers a smooth ride together with amazing levels of traction and control, especially when using the optional 20-inch, high-performance summer Pirelli P Zero tires.
Due to its additional weight, the i4 50 doesn’t handle as nimbly as an M3 or M4, but it is still a self-assured, exciting, and adaptable sports sedan. The M3 and M4’s stunning LED headlights and aero outside mirrors with carbon-fiber covers are also shared by the i4 M50. It won’t be confused with anything else or get lost in the parking lot.
The EPA estimates a meager 227-mile range for the i4 M50, compared 270 miles on 19-inch wheels, because to those large, sticky tires. Fortunately, the i4 M50 showed it can surpass those stated range estimates throughout my week of driving in New York and upstate. The i4 M50 could travel at least 260 miles under normal driving conditions.
The EPA awards the single-motor eDrive 40 variant with up to 301 miles for purchasers who place a high value on long-range. The i4 M50 has nearly the same range as a Tesla Model 3 Performance, which in real-world driving can travel 260–270 miles, but with clear luxury and handling advantages.
Driving the i4 in complete stillness with only the distant hum of its electric motors (or one motor) is wonderful. As with other EVs, however, owners can also select a digitalized soundtrack for the powertrain, in this case composed by renowned film composer Hans Zimmer. I consider this soundtrack to be the best of the current crop of synthetic EV tunes; it combines the frequencies of an actual BMW engine with a sci-fi flourish that a friend claimed sounded like whale calls. Drivers may, of course, turn off the phony powertrain sound whenever they choose.
Is there a heat pump in the BMW i3?
Heat pump technology Since an electric car lacks a combustion engine to provide thermal energy, heating is powered by electricity. Due of this, the BMW i3 offers an optional heat pump that automatically activates and draws energy from the surrounding air.
Can a BMW i3 be heated up?
Yes, the battery will warm up if you’re plugged in (even to 120 volts) and have a departure time set at least three hours in advance. The battery will be used to make up the difference at 120 volts because the load is more than what can be supplied by the cord. It’s not much, perhaps a percent or two, but. Several times I’ve started my car at 100% on L1 with a warm battery.
No. The battery will only be used by Climatize to pre-heat or pre-cool the cabin; the battery will not be pre-conditioned. The automobile must be plugged in, preferably at Level II, and a preset period must be specified. Oddly, this process is still referred to as charging even though it is only being used for battery conditioning. This needs to be set at least three hours before your leave, as the other member mentioned. If not, the cabin will only be heated or cooled.
