Enhanced Power and Efficiency: BMW’s Updated 4 Series, M340i, and M240i

Discover the latest updates from BMW, featuring improved engine performance, enhanced fuel efficiency, and exciting new features for the 4 Series, M340i, and M240i models.

Enhanced Power and Efficiency: BMW’s Updated 4 Series, M340i, and M240i

BMW has officially revealed the latest updates to its 2, 3, 4, and 5 Series models, emphasizing enhanced power, improved efficiency, and exciting new features that cater to a wide range of drivers.

Power Boost with Better Efficiency

With the introduction of these refinements, BMW has focused on delivering a more exhilarating driving experience across its lineup. Notable among these updates are the M340i and M240i models, which benefit substantially from powertrain enhancements. The M340i xDrive saloon and Touring variants now boast a revamped 3.0-litre six-cylinder engine, which sees an impressive output of 387bhp—a gain of 18bhp over previous models. This performance leap is supported by an upgraded mild-hybrid system, enabling an increase in peak torque to a formidable 540Nm, up 40Nm from earlier versions.

The improvements don't stop there. The new powertrain will also be integrated into the M440i xDrive Coupé, Convertible, and Gran Coupé, as well as the BMW M240i xDrive Coupé. As a result, these models exhibit quicker acceleration, with every variant demonstrating a remarkable 0.1-second improvement in the dash from 0 to 62mph. For instance, the M340i xDrive saloon now completes this sprint in just 4.3 seconds, keeping pace with the acceleration records set by today’s high-performance electric vehicles (EVs).

Enhanced Fuel Economy and Emission Reductions

In a harmonious balance between power and efficiency, BMW has not compromised fuel economy for performance. In fact, the manufacturer reports notable improvements in fuel consumption across its updated models. For example, the BMW M240i xDrive Coupé has increased its fuel efficiency from 32.3mpg to 35.3mpg on the WLTP combined cycle, while reducing CO2 emissions from 200g/km to 183g/km.

These enhancements are not just number improvements; they reflect BMW's commitment to producing vehicles that are not only powerful but also environmentally conscious.

Innovative Features and Aesthetic Updates

Beyond performance refinements, BMW has also introduced several new features designed to enhance the driving experience. The 2 Series Gran Coupé now offers a stylish Cape York Green paint option, allowing owners to express their personality through color. Moreover, the BMW 4 Series Gran Coupé and the BMW i4 are now available with optional Adaptive LED Headlights, improving visibility and safety during nighttime driving. Additionally, the i4 features innovative laser rear lights, adding a touch of modernity to its design.

For the business-minded, BMW's 5 Series has also seen improvements with the addition of a coat hook on the B-pillar as standard across all models. In terms of technology, the My BMW app has been updated to include a comprehensive Charging Guide aimed at helping electric vehicle owners optimize their charging routines.

Conclusion: The Future of BMW

As BMW continues to evolve, these recent updates to the 4 Series, M340i, and M240i models underscore the brand's dedication to blending performance, efficiency, and luxury. With advancements in engine technology, fuel economy, and innovative features, BMW reaffirms its position as a leader in the automotive industry.
