In case you were wondering there is overlap between the new GT and the outgoing SLS.
Aspects of the structure came from SLS
Front Suspension from SLS
Well, some of the GT is actually closely descended from the SLS. The central part of the aluminium body structure is closely related. Almost all the body is aluminium, by the way, helping to keep it light.
The front suspension is also from the SLS, though the rear end is new. It's the same width as the SLS (and feels wide for sure) but handily shorter both in the wheelbase and overall.
