Mercedes's Porsche Panamera rival - the AMG GT 4-door Coupe has been given a new entry-level variant. Powered by a 6-cylinder, 3.0-litre petrol engine which is the same as the earlier unveiled AMG GT 53 4MATIC+, the new AMG GT 43 4MATIC+ gets a lower state of tune. The other variants available in the lineup are the GT 63 and GT 63 S, both of which pack a 4,0-litre V8 biturbo engine.
