Engine and Performance
6.0/10

The 2023 Mercedes-AMG CLA 45 is widely known for its performance, thanks to its impressive turbocharged 2.0L Inliine 4 powertrain. The 2023 CLA 45 makes around 382 horsepower and 354 lb-ft of torque with the benefit of a water, air, and oil-cooled turbo that can raise up to 27 psi. The 8-speed AMG Speedshift dual-clutch transmission (DCT) routes the power to all four wheels of the car. The new AWD system and transmission which was featured for the first time in the 2022 CLA 45 is an advancement over the boring and slow drivetrain and seven-speed transmission found in the CLA 35. To say the least, every tiny component of the 2023 CLA 45 has improved significantly as compared to its previous generations. The 2023 edition of the car will finish the 0-60 mph sprint in under four seconds, as claimed by the brand. The CLA 45 offers its drivetrain with an active torque vectoring differential at the back that can truly generate power-on oversteer.

The CLA 45 offers the quickest acceleration on the 0-60 MPH mark than the Audi S4, M340i, and the CT4-V Blackwing. Similarly, it also leads in terms of the quarter mile timing as compared to the S4 and the M340i. The top speed of the 2023 CLA 45 is 155 MPH (governor limited) which justifies its segment.

2023 Mercedes-AMG CLA 45 Ride and Handling

The 2023 Mercedes-AMG CLA 45, unlike its younger sibling, the CLA 35, comes with impressive torque-splitting technology that lets the sports car be driven like an RWD automobile. This means oversteer action is available at all times, and not just in Drift Mode provided by the brand. Even in Sport mode, the CLA 45 will ride all composed under heavy throttle loads, whereas the front wheels retain enough drive to keep the car in the right direction. On city roads, the 2023 CLA 45 is refined and remains calm. However, it can come out as a bit stiff sometimes. Hence, in our opinion, It is recommended the optional adaptive damping kit, but the target buyers of this beast will understand that some stiffness is to be expected.

2023 Mercedes-AMG CLA 45 Braking Performance

The 2023 Mercedes-AMG CLA 45 comes with disc brakes on all four of its wheels. It comes with 13.8-inch front brake rotors and 13-inch rear brake rotors.

The 2023 CLA weighs around 3,505 lbs.
