Specification. Taking the lead right away: the strikingly sporty design makes the Mercedes-AMG A 45 models clearly distinguishable from the Mercedes-AMG A 35 4MATIC and the AMG Line. The distinctive front apron, the AMG-specific radiator trim and the bonnet with power domes make the Mercedes-AMG A 45 models really stand out. The front wings, which are far wider than those of the Mercedes-AMG A 35 4MATIC, impressively reflect the abundance of driving enjoyment on offer.
