Electric vs. Gasoline: BMW X3 and iX3 Range Test Comparison





Long-Distance Showdown: Electric Versus Fuel Efficiency
The Evolving Landscape of Vehicle Range
For many prospective electric vehicle (EV) owners, the concern of 'range anxiety' persists. This apprehension stems from unfamiliarity with EV charging infrastructure and the traditional benchmarks set by gasoline-powered cars. However, advancements in EV technology are continually narrowing the gap, and sometimes even surpassing, the travel distances achievable by internal combustion engine (ICE) vehicles on a single fill-up. To illustrate this progress, a recent video from 'Chasing Cars' conducts a compelling real-world experiment.
The Australian Road Trip Challenge: iX3 vs. X3
The test involved two hosts embarking on a journey from Sydney, Australia, to Byron Bay, piloting a BMW iX3 50 xDrive and a BMW X3 M50 xDrive. The experiment was designed to mimic typical driving scenarios. Both vehicles were operated on regular roads, maintained their respective Eco modes, and utilized their most energy-efficient climate control settings. Drivers adhered to speed limits and made necessary stops, ensuring the results would reflect a realistic road trip experience.
Initial Range Projections and Surprising Efficiency
The total distance for the trip spanned approximately 459.8 miles (740 km). At the outset, the electric iX3 displayed an estimated range of 692 km (430 miles), seemingly insufficient for the entire journey. In contrast, the gasoline-powered X3 M50 boasted a projected range of 784 km (487 miles) after just 30 km of travel, indicating a significant advantage. Curiously, early efficiency calculations for the iX3 suggested it might complete the trip with some battery life remaining, defying its initial range estimate.
Performance and Power Differences
It is noteworthy that the gasoline-powered X3 M50, despite its higher range, is equipped with a 3.0-liter turbocharged inline-six engine. While benefiting from mild-hybrid technology, this engine delivers 393 horsepower and 428 lb-ft of torque, making it the most fuel-intensive X3 model currently available, excluding the upcoming X3 M. Interestingly, the electric iX3 M50 actually surpasses its gasoline counterpart in power, generating 463 horsepower and 476 lb-ft of torque.
The Final Verdict: A Close Contest
Ultimately, the BMW iX3 managed to cover an impressive 747 km (464 miles) on a single charge. This significantly exceeded its EPA-rated range of 434 miles, falling short of Byron Bay by only 23 km (14.2 miles). The X3 M50, however, successfully reached its destination with a substantial 332 km (206 miles) of fuel still in its tank, undeniably winning the range test. Nevertheless, the iX3's performance was remarkable, showcasing a range that few other EVs can currently achieve. This result highlights the impressive efficiency of BMW's mild-hybrid straight-six engine but also underscores the significant achievements of the iX3 in the electric vehicle landscape.
