Ferrari’s new model pegged for the 2007 Frankfurt auto show has turned out to be the new 430 Scuderia, and not the Challenge Stradale or Dino that everyone had been hoping for.

The new Scuderia is essentially the CS model in everything but name, having shed up to 100 kilograms through an extensive weight saving program.

The 430 Scuderia will be unveiled by Michael Schumacher at the Frankfurt show on September 11, where it joins the coupe and open-top Spider in the F430 family.

Output from the naturally aspirated 4.3-liter V-8 jumps to 523 horsepower at a lofty 8,500 rpm and the curb is just shy of 1,250 kg.

Other changes over the regular F430 model include the new exhaust system, evidenced by the new tailpipes. There is also a new traction control system that combines the E-Diff electronic differential and the F1-Trac traction and stability control in a single integrated system, plus an upgrade to the Superfast F1 gearbox software, which reduces gearchange times to just 60 milliseconds.
