Those who subscribe to the idea that a driver’s car must first and foremost possess good steering will be pleased to hear that the A45 S makes a strong start. This set-up, which uses speed-dependent gearing, isn’t immune to deflection or the odd flicker of torque steer, but it develops convincing weight and prizes accuracy.
As you’ll find with AMG’s more serious, rear-driven models, there’s also a communicative vein of feel that makes it easy to guide and place the car with satisfying conviction on tight, twisting roads. By the standards of today’s hatchbacks, with their electrically assisted racks, this set-up ranks as one of the best, although fractionally more self-centring action would make it unquestionably the class of the field.
The next step in your journey of A45 S discovery is to find that roadholding is every bit as jowl-tuggingly adhesive as you would expect, given this car’s ability to cleverly apportion drive between its 245-section tyres. Aggressively turn in to corners and there is but a tiny slither of latency before the tall body responds, and even this chink in the armour is exposed only during extreme direction changes. Most of the time, the centre of gravity feels low, the car’s composure largely unflappable, with grip and traction the dominant forces.
But what about Drift mode, which throws as much of the engine’s torque to the rear outside wheel as possible? Despite the marketing campaigns, the way this – and all of the more aggressive settings for the AMG Dynamics chassis electronics – mostly manifests is not with armfuls of opposite lock but with an awesome level of neutrality. Through corners, the rear axle can snag the inside brake and push drive to the outside, which essentially eliminates understeer on the road but can sometimes result in glimmers of rotation that require only an opening of steering angle. Of more significance is that, even when driven within the limits of grip, the A45 S feels more involving, serious and sophisticated on the move than any hatchback counterparts, be they driven by both axles or only the front.
