May 5 (GMM) A spokeswoman for the formula one team Toro Rosso on Monday confirmed that its 2008 car, the STR3, will not be making its grand prix debut in Turkey this weekend.

The Faenza based squad had hoped to begin racing the Ferrari-powered car, which is based on Red Bull Racing's RB4, at Istanbul, after development of its 2007 single seater was ceased.

The spokeswoman said the delay is because the team has not had enough time to produce adequate spare parts for Turkey, following Sebastien Bourdais' crash with a prototype model at the pre-Barcelona group test.

The next race after Sunday's Turkish grand prix is in Monaco late this month, but it has been suggested that it might be unwise to debut a new car on the armco-lined street circuit.

The STR3's debut may therefore have to wait until the subsequent Canadian grand prix, in June.
