Compare performance (601 HP vs 469 HP), boot space and price (49,400 £ vs 60,800 £ ) at a glance. Find out which car is the better choice for you – BMW i4 or BMW iX3?
The BMW i4 and BMW iX3 represent two distinct approaches to electric mobility from one of the automotive industry’s most prestigious brands. While both vehicles embrace BMW's commitment to sustainability and performance, they cater to different needs and preferences. This comparison delves into the technical specifications and innovative features of these two electric powerhouses.
The BMW i4 is classified as a hatchback, seamlessly blending sporty aesthetics with practicality. Its sleek profile is designed to enhance aerodynamics while providing ample trunk space of 470 liters, making it suitable for both urban commuting and longer journeys.
On the other hand, the iX3 is an SUV, offering a more robust and elevated stance. With a trunk capacity of 510 liters, it combines the benefits of an SUV’s spaciousness with the efficiency of electric power. At a length of 4734 mm and a width of 1891 mm, it projects a commanding presence on the road.
The i4 offers multiple power outputs ranging from 286 HP up to an exhilarating 544 HP, catering to varying performance preferences. The lower variants accelerate from 0-100 km/h in just 6 seconds, while the high-end performance variant achieves this in an impressive 3.9 seconds. The i4’s dual drivetrain options (Rear-Wheel Drive and All-Wheel Drive) provide enhanced versatility and handling.
In comparison, the iX3 comes equipped with a single power output of 286 HP, accelerating from 0-100 km/h in 6.8 seconds. It operates on Rear-Wheel Drive only, which still delivers a spirited driving experience often associated with BMW vehicles, but lacks the versatility of the i4's drivetrain options.
When it comes to battery capacity, the i4 offers options of 67.1 kWh and 81.3 kWh, providing electric ranges between 485 km and 582 km depending on the variant. This versatility allows drivers to choose a model that suits their driving habits, whether for short daily commuting or extended road trips.
The iX3 features a 73.9 kWh battery, achieving an electric range of up to 471 km. While it doesn't quite match the i4’s maximum range, it remains competitive in the SUV segment, offering sufficient range for family excursions and everyday use.
In terms of efficiency, the i4 shines with consumption figures ranging from 15.6 kWh/100 km to 18 kWh/100 km depending on the variant. This showcases its performance-oriented design without compromising on effectiveness.
Conversely, the iX3 has a slightly higher consumption rate at 17.6 kWh/100 km, which is common for SUV designs due to their larger size and weight. However, it still stands out within its segment for offering zero tailpipe emissions.
Both models come equipped with BMW’s latest iDrive system, featuring a high-resolution display, navigation, and various connectivity options to enhance the driving experience. However, the i4 boasts additional performance-oriented technologies, including advanced driving dynamics control and optional M performance upgrades, a staple of the brand’s sporting heritage.
The iX3, while not as performance-driven, offers an array of driver assistance systems, ensuring safety and convenience for family driving. Features like adaptive cruise control, lane-keeping assist, and parking assistant are readily available.
In conclusion, the choice between the BMW i4 and BMW iX3 boils down to personal preferences and lifestyle needs. The i4 is an excellent option for those seeking sports car dynamics without sacrificing everyday practicality, while the iX3 serves as the ideal family SUV with space and comfort. Both vehicles cement BMW's status as a leader in the electric vehicle domain, combining innovation, performance, and sustainability.
