The 2021 AMG CLA 45 is capable of making a 0-60 MPH sprint in 4 seconds along with a quarter-mile in 12.3 seconds. Mercedes has limited the top speed to 155 MPH. The turbo 5 cylinder unit powering the Audi RS3 somewhat matches the performance of the AMG CLA 45. The BMW M340i can develop the same power as the AMG CLA 45. However, the acceleration is laggy due to its heavy weight. 

How well does the 2021 Mercedes-AMG CLA 45 handle?

The four-wheel independent suspension system does wonders with the handling of the 2021 Mercedes-AMG CLA 45. The adjustable steering offers the best in class response and grip while cornering. The front struts and wishbone suspension work in line with the rear suspension to offer optimum comfort and stability to this performance Coupe. 

The CLA 45's Multistage Electronic Stability Program(ESP) optimizes the brakes for better control and well-planted torque. A safety aid like Dynamic Cornering Assist allows the vehicle to remain stable while making a sharp move around corners. The Coupe comes with an array of performance assistive features that just enhance the overall driving dynamics. 

2021 Mercedes-AMG CLA 45 Braking Performance

The 2021 Mercedes-AMG CLA 45 is one of the fastest Coupes in the market, doing the 0 to 60 mph sprint in dead 4 seconds. With such acceleration comes great responsibility for the brakes. The AMG CLA 45 offers a very responsive and powerful braking system, consisting of a large 13.8 inches ventilated disc in the front and a 13 inches disc in the rear.

There is an array of brake tech integrated nicely within the CLA 45 AMG, making it a safer bet among its rivals. The AMG CLA 45 gets an Adaptive Braking Technology along with predictive brake priming that is triggered once you apply the brakes, and the brake pads come closer to the discs, thus, maintaining the stability of the car while sudden braking. Also, there's an automatic brake drying system that uses an adequate amount of brake force to remove any moisture or water stuck to the discs.

2021 Mercedes-Benz AMG CLA 45 Coupe Safety

7.0/10

2021 Mercedes-AMG CLA 45 vs. 2021 Audi RS3

The Audi RS3 doesn't fairly beat the AMG CLA 45 when it comes to performance. The RS3 also offers limited interior space in the front row. Also, the cargo space is lesser compared to the CLA 45. In terms of safety features, the CLA 45 offers an array of aids compared to the RS3. Despite having a larger fuel tank, the RS3 fails to offer a decent driving range and fuel economy.

2021 Mercedes-AMG CLA 45 vs. 2021 BMW M340i xDrive

The BMW M340i is priced higher than the AMG CLA 45. The Bimmer costs around $1K more. Both cars produce almost similar power, but the M340i is slightly slower than the CLA 45 in terms of acceleration. The BMW boasts a spacious and practical interior. It has also been rewarded with IIHS's Top Safety Pick award.

2021 Mercedes-Benz AMG CLA 45 vs. 2021 Genesis G70 3.3T

The Genesis G70 is the least costly alternative in the highly expensive performance coupe market. Compared to the AMG CLA 45 that has got revamped recently, the G70 lacks on the features front. Though, it manages to keep itself cost-effective when compared to the German rivals. Between the two, the choice remains between value for money or the all-out German luxury and performance.

2021 Mercedes-Benz AMG CLA 45 Coupe Final Verdict

With an aesthetic design and theme, the 2021 Mercedes CLA 45 AMG is now available with better ergonomics and features. The performance car is well-placed among its German rivals. The most important rival is the Audi RS3. It closely competes against the RS3 in terms of driving dynamics and safety aids. The 2021 AMG CLA 45 remains majorly unchanged from the upgraded 2020 model. So, there is not much reason to go for a 2021 model that gets select new standard features like keyless entry and ignition, auto-dimming and power-folding mirrors, and blind-spot monitoring. However, one can go with the 2020 model to save some bucks while getting the luxury and performance of this AMG model.
