You're gonna get 17 more variants of the s650 and you're gonna like it goddamnit lol. In all seriousness, this is a little bit of what I was concerned about with the GTD. When that car was first shown off, I had concerns it would make getting excited for future s650 variants more difficult because we were already used to the most hardcore version right out of the gate. 

Yeah I agree. 

The 'thing' is...  The Ford 650 and 750 compete on price.  Using an 'in house' powertrain gives the Ford trucks a price advantage, particularly with the 7.3L gasoline engine.  If Ford were to offer a Cummins/Allison drive train their trucks would likely be very close in price to Freightliner, International, Mack, and the various PACCAR class 6 and 7 trucks.  Those trucks offer significant advantages over the Fords like wider option availability, better cabs, better dealer networks for medium duty sales and service, and better resale.  Ford would likely be under pressure to keep the 650/750 price lower than the competition, which would eat into whatever profits those models generate.  So, offering 'in house' powertrains exclusively in the 650 and 750 is the best thing Ford can do, I think.   The Ecotorq is a non-starter.  The costs of emissions certification would have to be spread out over a likely very small sales volume of a Ford class 7/8 truck, not to mention whatever tariffs would be slapped on it.  I think Ford-Otosan will increasingly align with Iveco and focus on eastern European and Asian markets.  

With Ford Performance being replaced with Ford Racing, maybe SVT will make a return. A new Mustang SVT Cobra would be nice.

I was under the impression that vehicles over a certain GVWC don't have to or have lower standards to meet?

I think its the spoiler causing to look that way...esp if their is cover over it.

I’d be excited for the 4 door mustang, off road mustang, or a new GT. Don’t really care to see a new trim on the regular mustang.

Sadly, you are most likely correct. It's just that using the Cummins/Allison combo is probably not worth the cost expense vs using a Ford sourced unit for the amount of projected sales. 

Am I nuts or does the rear end of that, the overall profile, look higher and boxier than the coupe? It could just be a spoiler under there that's messing with the lines, but it's hard to tell. It just looks a little more upright to me. 

I guess it's possible if they reveal multiple things.   But this screenshot just looks like another Mustang (2-door) derivative
