The 2016 Mercedes-Benz CLA Class emerges as a compelling option for those seeking a blend of luxury and sporty performance in a compact sedan. This model year offers two distinct personalities: the CLA250, focused on efficiency and everyday driving, and the high-performance CLA45 AMG, engineered for exhilarating speed and dynamic handling. Both models share the hallmark Mercedes-Benz quality and design, but cater to different driving preferences.
Engine and Performance Dynamics
Under the hood of the CLA250 lies a turbocharged engine calibrated for a balance of power and fuel economy. This setup prioritizes smooth acceleration and efficient cruising. Stepping up to the CLA45 AMG unleashes a significantly enhanced version of the same powertrain. Mercedes-AMG engineers have substantially modified the engine with increased turbo boost and a higher redline, pushing the boundaries of performance. The 2016 AMG variant received a notable power boost compared to its initial iterations, now delivering an impressive 375 horsepower and 350 lb-ft of torque. This power surge translates to a breathtaking 0 to 60 mph acceleration time of just 4.1 seconds, placing it in the realm of high-performance vehicles like the Tesla Model S in terms of sheer speed.
Transmission and Drive Configurations
Both the CLA250 and CLA45 AMG utilize a 7-speed dual-clutch transmission. However, the AMG model features a beefed-up transmission to effectively manage its increased torque output. While the CLA250 is standard with front-wheel drive, Mercedes-Benz offers all-wheel drive (4MATIC) as a $2,000 option, enhancing traction and stability, particularly in adverse weather conditions. For the CLA45 AMG, all-wheel drive is standard, a necessity to harness its considerable power. The 4MATIC system intelligently distributes torque, seamlessly transitioning from a predominantly front-wheel bias in normal driving to a 50/50 split between front and rear axles when needed. This dynamic torque distribution results in smoother launches and gear changes compared to a purely front-wheel-drive system.
Driving Experience and Handling
The driving dynamics of the CLA Class differ noticeably between the CLA250 and CLA45 AMG models. The CLA250, in its standard configuration, employs a retro column shifter for selecting drive modes. In contrast, the AMG reverts to a console-mounted shift lever, a more traditional placement for performance-oriented vehicles. Both models are equipped with steering-wheel-mounted paddles for momentary manual gear shifts, offering driver engagement when desired. A standard stop/start system is incorporated in all CLA models to enhance fuel efficiency. However, some drivers may find the system’s engine shut-off and restart to be somewhat noticeable, particularly at longer stops.
The CLA250’s tuning prioritizes fuel efficiency, aiming for its EPA-rated 30-mpg combined fuel economy. This is achieved through rapid and frequent upshifts. While gear changes are smooth at higher speeds, demanding quick downshifts on highways might require a moment for the transmission to respond. To enhance responsiveness in the CLA250, drivers can switch from the default Eco mode to Sport or Manual shift modes. These modes provide a more engaging driving experience but may compromise fuel efficiency.
Conversely, the CLA45 AMG delivers a distinctly different shifting experience. Its driver-selectable modes, including Comfort, Sport, and Manual, are managed through a rotary knob and the Dynamic Select function. The AMG’s transmission programming and rev-matching capabilities result in quicker, crisper shifts. In manual mode, the driver assumes full control over gear changes, aligning with AMG’s focus on driver engagement and performance.
Steering, Suspension, and Ride Comfort
Both front-wheel and all-wheel-drive CLA250 models are equipped with electric power steering and standard 17-inch run-flat tires. Upgrading to 18-inch wheels is possible, with options for summer tires and perforated disc brakes. A “sport” suspension, initially standard but later optional, lowers and stiffens the ride. For optimal ride comfort in the CLA250, particularly with the sport suspension, sticking with the 17-inch wheels is advisable, as the 18-inch wheels can amplify ride stiffness. The steering system in the CLA250, while offering quick responses due to its effort and ratio adjustments as you steer away from center, retains the typical numbness associated with electric power steering systems. The all-wheel-drive CLA250 arguably offers a more dynamically sound driving experience, effectively harnessing the engine’s power.
The CLA45 AMG features uniquely tuned steering, suspension, and brakes. It corners with even greater flatness than the CLA250. Its electric power steering rack has a fixed ratio, although steering effort still adjusts based on vehicle speed. The CLA45 AMG rides approximately an inch lower and has a rear track that is nearly half an inch wider than the CLA250. The suspension employs a sophisticated multi-link setup at both front and rear, along with stiffer components to manage the higher torque and traction demands. Thicker anti-roll bars and individual wheel braking for torque vectoring further enhance cornering capabilities. Standard 18-inch wheels with performance tires are standard on the AMG, with optional 19-inch wheels available.
AMG Performance and Handling Prowess
The culmination of these AMG enhancements results in explosive acceleration, exceptional grip, and remarkably neutral handling for the CLA45 AMG. The all-wheel-drive system effectively eliminates understeer, while the electric steering mitigates any potential torque steer. The AMG’s Racestart launch control system enables rapid departures from a standstill, optimizing the dual-clutch transmission for maximum acceleration. Unlike the CLA250, the CLA45 AMG provides a more connected feel to the road surface, offering a more engaging and visceral driving experience. The 2016 CLA45 AMG stands as a finely tuned and remarkably quick compact sedan, representing a significant step up in performance from the standard CLA250.
