Priced at $128,400, before on-road costs, the Limited Edition attracts a premium of $7400 over the standard A45 S4MATIC thanks to unique exterior paintwork, interior design upgrades and standardised AMG packaging.
That makes it even more expensive than the Audi RS3 ($95,715) and the BMW M240i ($99,900, both before on-road costs).
