Switching from an older Audi S4 to the 2014 Mercedes Cla 45 Amg is a significant step up, particularly in interior refinement. Opting for the AMG exclusive package elevates the cabin feel with leather-wrapped dashboard and premium materials. Choosing a 2015 or newer model year AMG would bring further enhancements like the updated screen and steering wheel, which are compelling reasons to consider a newer car over a pre-owned Edition 1 for an improved interior ambiance. Having experienced both, here’s a detailed comparison focusing on the 2014 Mercedes CLA 45 AMG from a features and performance standpoint, highlighting what stands out and what could be improved compared to an older Audi S4.
Feature Set: Audi S4 vs. 2014 Mercedes CLA 45 AMG
When it comes to features, both cars offer a range of functionalities, but they differ in execution and user experience. Here are some feature-specific observations comparing the older Audi S4 and the 2014 Mercedes CLA 45 AMG.
Aspects Missed from the Audi S4
Certain details in the Audi S4 were more user-friendly in daily use. For instance, the sunvisor mirror covers in the Audi slide open smoothly, whereas the Mercedes uses a hinged flap. This flap design in the CLA 45 AMG can obstruct light from the sunvisor bulb when open, a minor inconvenience, especially for tasks like applying makeup in the car.
The multi-function steering wheel in the Audi S4 featured a selector wheel that allowed for direct library or radio station searching before selection. In contrast, the Mercedes system cycles through the list as you search, which can be less efficient for quickly finding a specific item. Another point of difference is the fuel consumption display. The Audi S4 provided both current and average fuel consumption, while the 2014 CLA 45 AMG only displays the average since start or reset, lacking real-time fuel consumption data.
Voice control in the Audi S4 felt more intuitive and responsive. It seemed to understand commands more readily compared to the initial experience with the CLA 45 AMG. Navigating through settings for different modules like radio or navigation was also more straightforward in the Audi’s interface. Lastly, the Bang & Olufsen sound system in the Audi S4 was notably superior to the Harman Kardon system in the Mercedes, offering a richer and more immersive audio experience.
Advantages of the 2014 Mercedes CLA 45 AMG in Features
Despite missing some aspects of the Audi, the 2014 Mercedes CLA 45 AMG excels in several feature areas. The handbrake operation in the CLA 45 AMG is more intuitive; pressing the brake pedal harder at a standstill engages the handbrake, unlike the electronic handbrake system in the Audi S4 (unless equipped with the optional Auto-Hold, which was not commonly specified).
The driver information display in the Mercedes is better organized, presenting categories from left to right and options within each category vertically. This layout is more visually clear and easier to navigate while driving. The CLA 45 AMG also provides a dedicated screen displaying essential temperatures – oil, water, and gearbox – alongside the current gear and speed. The temperature gauges change color from blue to white once operating temperature is reached, a helpful visual cue.
Navigation in the 2014 CLA 45 AMG is enhanced, notably allowing for the input of geo-coordinates, a feature appreciated by those who need precise location input. Switching between Sport and Manual modes is more convenient in the Mercedes with a dedicated button, as opposed to manipulating the gear selector in the Audi. Furthermore, the true manual mode in the CLA 45 AMG, which holds gears without automatic up-shifting, offers more driver control.
The panoramic roof in the Mercedes is a significant upgrade over the sunroof in the Audi S4. The Audi’s sunroof was prone to considerable wind noise, often requiring it to be kept closed. In contrast, the panoramic roof of the CLA 45 AMG allows for open-top driving with minimal wind noise, making it usable more frequently. The map reading lights in the Mercedes are designed to illuminate only the lap area of the passenger side, minimizing windscreen reflection and glare, although this reduces light for tasks requiring broader illumination in the passenger area. Finally, the Park Distance Control (PDC) in the Mercedes is always active, eliminating the need to manually switch it on when parking, a convenient feature despite the screen potentially obstructing the PDC display at times.
Additional Impressive Features
Beyond direct comparisons, the 2014 Mercedes CLA 45 AMG includes several impressive features, some of which are also available in Audi models but were particularly appreciated in this experience. Blind Spot Assist functions effectively, enhancing safety during lane changes. Collision Prevention Assist warns if the car ahead is slowing down and can even initiate braking if necessary, crucial for maintaining attention in varied driving conditions. The wide-view rear-view camera aids significantly when reversing from parking spots, especially between larger vehicles. Self-parking, while sometimes slower than manual parking, proves useful in tight spots or for parallel parking scenarios.
Performance Dynamics: Audi S4 vs. 2014 Mercedes CLA 45 AMG
Performance is where the 2014 Mercedes CLA 45 AMG truly distinguishes itself, although the transition from the Audi S4’s V6 has its nuances.
Performance Aspects Favored in the Audi S4
The Audi S4’s 3.0 TFSI V6 engine is remembered fondly for its linear power delivery and readily available torque across the rev range. This engine provided an addictive driving experience, making the S4 feel surprisingly quick, especially at higher altitudes (1500-1600 meters above sea level) where it could outperform naturally aspirated V8s. The S4 was also praised for its ease of driving; throttle response was immediate, and the engine was forgiving even in the wrong gear due to its broad torque curve. The supercharger whine added to the auditory driving pleasure. While on paper the Audi S4 had slightly lower power figures (245kw) compared to the CLA 45 AMG (265kw), dyno tests showed the Audi’s figures to be potentially underrated, delivering strong real-world performance. Lastly, finding a comfortable driving position seemed easier in the Audi S4.
Performance Advantages of the 2014 Mercedes CLA 45 AMG
Despite missing the V6’s characteristics, the 2014 Mercedes CLA 45 AMG ultimately delivers superior performance. While it might initially feel subjectively slower than the Audi S4 due to turbo lag at altitude, it is objectively quicker. Launch Control in the CLA 45 AMG enables significantly faster acceleration times compared to the S4. At higher speeds (200km/h+), the CLA 45 AMG feels considerably more planted and stable, inspiring confidence at speeds where the Audi S4 could feel less composed.
The handling balance of the AMG is notably better, offering superior cornering agility. Brake balance in the CLA 45 AMG is also more refined, providing consistent and stable braking performance without the instability issues experienced with the Audi S4 under heavy braking (which required aftermarket brake upgrades and compound adjustments). The gearbox in the 2014 Mercedes CLA 45 AMG (specifically later 2015 models and onwards) is improved, addressing earlier criticisms of jerky 1st to 2nd gear changes. Gear changes are quicker, crisper, and more responsive to paddle inputs compared to the Audi’s S-Tronic. The true manual mode allows for extended gear holding and more effective engine braking. Steering feel and road feedback are significantly enhanced in the CLA 45 AMG, providing a more connected and informative driving experience. Launch Control in the AMG is described as “brutal,” offering intense acceleration. However, pulling away quickly without Launch Control requires a specific technique involving engaging auto-hold to build boost, which can feel less intuitive than the Audi’s more immediate throttle response in everyday driving scenarios.
Fuel Efficiency
An unexpected benefit of switching to the 2014 Mercedes CLA 45 AMG is improved fuel economy. Contrary to some expectations, the CLA 45 AMG proves to be more fuel-efficient than the Audi S4, and even compares favorably to cars like the BMW M235i. Real-world figures show the Audi S4 averaging 11.5-12.5 L/100km in civilized driving and 14-15 L/100km with spirited driving. The CLA 45 AMG, in contrast, achieves 9.0-10 L/100km in similar civilized conditions and 10.5-11.5 L/100km with more aggressive driving. This represents a notable improvement in fuel efficiency without sacrificing performance.
Conclusion
The 2014 Mercedes CLA 45 AMG presents a compelling package, especially for those upgrading from an older performance sedan like the Audi S4. While some user-interface aspects and the V6 engine of the Audi S4 are missed, the CLA 45 AMG surpasses it in overall performance, handling, stability at high speeds, and even fuel efficiency. Its advanced features, combined with a more engaging driving experience, make the 2014 Mercedes CLA 45 AMG a strong contender and a worthy upgrade for enthusiasts seeking a high-performance compact sedan. For anyone considering a pre-owned performance vehicle, the 2014 Mercedes CLA 45 AMG remains a benchmark in its class, offering a blend of daily usability and thrilling driving dynamics.
