If GM were to revive the Syclone name, I would much rather see it on the smaller Canyon chassis, to stay a little closer to the originals roots. Use the 3.0TT or 3.6TT Cadillac V6 for 450-500hp and keep it AWD.
Jeep was not mentioned, however with somewhat of a good reason - the 'Jeep' truck already entered the market. Well, maybe.. (A matter of opinion).
I looked at the prototype (2 door), and was somewhat interested. Poof!?! It became a four-door SUV with a short (60") bed, no option for a 2-door cab, and no option for a longer (6' - 8') bed? The result looks more like a regular Jeep, which has had a short bed added onto it..
Guess there isn't much of a marked for a 2-door vehicle with an 8-foot bed (or even a 6-foot 'short bed', for that matter)..
Not sure what happened to the Avalanche but GM had a reason to stop making it. I suspect it. Was not a cheap truck to build vs a more popular crew cab.
I am a GMC guy and loved the Syclone. But what many forget is very few were sold and likely little money was made due to the expense and high cost to build in low volume.
The Fiat based trucks were of no interest. Anything FWD base as a truck is a gamble outside the Brat.
The RT never set the world on fire and the Lighting was a great truck but sales were not spectacular and Ford needs income.
Ranchero or even an El Camino would be a limited interest item today. I love them but low volumes today are difficult to justify today at low cost.
