Test Driver Ratings & Comments

Acceleration commentsIn Comfort-transmission mode, the CLA45 leaves the line lazily as the clutch engages, but once under way, the acceleration is noticeably strong and remarkably linear. There's an obvious shove from the seat. At wide-open throttle, the upshifts occur at the same rpm in either Comf or Sport mode (which is several hundred rpm below redline) and are both smooth and quick-ish -- with Sport mode producing that now-trademark AMG upshift "burp" from the exhaust like the big boys do. Unlike in our long-term CLA250, selecting Manual shift mode doesn't result in default auto-upshifts; rather, the engine will rev up to the limiter and stay there until the next paddle-requested upshift occurs. I tried to extend the shifts to a higher rpm than it did in auto, but because manual-shift requests take time to process, I found it difficult to match the precision that Sport Drive provides -- which is what produced the best runs. Also, launch mode (which revs the engine to 3,000 rpm before the driver releases the brakes) produces very consistent times, over and over, as the shift speed and harshness also increased. There's still room for improvement in this regard, however. Perhaps it's to protect the driveline, but the clutch engagement is still rather slow and deliberate as the car still leaves the line rather gently. In the end, the results are still admirable and worthy of the AMG designation. This is a fast car.
Braking commentsIn everyday use, the CLA45's brake pedal feels perhaps too firm, jumpy and too sensitive, but in simulated panic stops it feels terrific. The pedal remains solid, consistent, and the stopping distances were all within 1 foot of one another across five stops -- and these aren't even the upgraded brakes that are available. Every stop was straight and with very little dive. Very good brakes.
Handling commentsSlalom: With the electronic stability system (ESC) in Sport Handling mode, the CLA is remarkably "free" and will allow the tires to slide (within prescribed limits) before reining the fun in. I found that if I allow the front tire to slide (understeer), ESC will punish with major brake application, causing the car to go straight (into a cone) despite the steering wheel being pointed in another direction. If, however, I cause the rear tires to slide (oversteer), it will allow a remarkable amount, especially if I am also hard on the gas pedal. I like how well the chassis responds to throttle input in such a predictable manner and I used this to come tantalizingly close to a 70-mph slalom pass. Steering is very direct and highly responsive, but I never felt like I could tell what the front tires were doing or about to do through the wheel. This was left for me to observe rather than feel. With ESC in default "ON" mode, the understeer punishment remains, but the allowance for oversteer is removed and it simply takes the throttle away to disallow it. Skid pad: A similar result here. With ESC in Sport Handling mode, the CLA45 allows the rear of the car to slide ever so slightly, producing a better result than in ESC "ON" mode. Steering, while precise, still doesn't offer what I'd categorize as "feel" but rather "resistance" as speed increases.
