The 2021 BMW X4 30d is a part of the G02 LCI facelift, offering a fresh take on the popular Sports Activity Coupe (SAC) design. With its sleek lines and powerful engine, this model is designed to appeal to those who want a blend of luxury, performance, and practicality. Whether you're navigating city streets or embarking on a long road trip, the X4 30d promises to deliver a dynamic driving experience.

Understanding the Key Terms

Before diving into the specifics, let's clarify some terms. The '30d' refers to the engine type, a 3.0-liter diesel engine with 286 horsepower. 'Mild Hybrid' means the car uses a small electric motor to assist the engine, improving fuel efficiency and reducing emissions. 'xDrive' is BMW's all-wheel-drive system, providing better traction and stability. 'Steptronic' is BMW's automatic transmission, allowing for smooth gear changes.

Performance and Efficiency

The BMW X4 30d is powered by a 3.0-liter inline-six diesel engine, producing 286 horsepower and 650 Nm of torque. This engine, combined with an 11 Hp electric motor, offers a robust performance with a 0-100 km/h (0-62 mph) acceleration time of just 5.7 seconds. The top speed is an impressive 245 km/h (152 mph), making it suitable for both city driving and highway cruising.

Fuel efficiency is a strong point, with a combined consumption of 6.1-7 liters per 100 km (38.56 - 33.6 US mpg). The mild hybrid system helps reduce CO2 emissions to 161-182 g/km, adhering to the Euro 6d emission standards.

Design and Features

The X4's design is both sporty and elegant, with a distinctive coupe-like silhouette. Inside, it offers a spacious cabin with seating for five and a trunk space ranging from 525 to 1430 liters, accommodating both daily errands and weekend getaways. The interior is equipped with high-quality materials and advanced technology, including a user-friendly infotainment system.

Practicality and Usability

For city dwellers, the X4's compact dimensions (4751 mm in length) and all-wheel-drive system make it easy to maneuver and park, even in tight urban spaces. The high ground clearance (204 mm) and robust suspension system ensure a comfortable ride over rough roads.

For families, the ample trunk space and comfortable seating make it a practical choice. The towing capacity of up to 2400 kg with brakes is ideal for those who need to haul trailers or caravans.

Strengths and Weaknesses

  • Strengths: Powerful engine, efficient mild hybrid system, luxurious interior, and excellent handling.
  • Weaknesses: Higher price point, diesel engine may not be suitable for all regions due to emission regulations.

Conclusion

The 2021 BMW X4 30d is a versatile vehicle that excels in performance, efficiency, and luxury. It's well-suited for those who value style and power, whether for city driving or long-distance travel. Consider what features are most important to you. Do you need the extra power for towing, or is fuel efficiency your top priority?
