The four-cylinder engine delivers extremely agile drive power in two output ratings: with 310 kW (421 PS) as the S-model and with 285 kW (387 PS) in the base version. The new compact sports cars absolve the sprint from zero to 100 km/h in record time: the GLA 45 S 4MATIC+ requires just 4.3 seconds, while the base model GLA 45 4MATIC+ gets up to speed in 4.4 seconds. The top speed of the base model is electronically limited to 250 km/h, while the S-model is allowed to leave the factory with a top speed of 270 km/h.
Apart from its pure performance figures, the new engine has an immediate response. To this end, the torque curve was carefully balanced (“torque shaping”): the peak torque of 500 newton metres (480 newton metres for the base version) is available in a range of 5000-5250 rpm (4750-5000 rpm in the base version). With this configuration, the AMG engineers have achieved a power delivery akin to a naturally aspirated engine.
