The Dallara T12 or Dallara FR35-12 is a racing car developed by Italian manufacturer Dallara for use in the World Series Formula V8 3.5, a series originally formed from the World Series by Renault top category. The T12 is the third generation of car used by the World Series by Renault/WS Formula V8 3.5, and was introduced at Silverstone on August 24, 2011.[2]
The T12 chassis featured a new, 530bhp V8 engine supplied by British firm Zytek Motorsport and designated as ZRS03. The car also featured a new gearbox developed by Ricardo and a Drag Reduction System similar to the one first used in the 2011 Formula One season. As the WS Formula V8 3.5 is a spec series, the T12 is raced by every team and driver on the grid.
