More Renault engine trouble for Toro Rosso during filming day at Misano 13 February, 2014 Daniil Kvyat in the Toro Rosso STR9 at Jerez With the second stanza of Formula 1′s brief testing season fast approaching, it seems that Renault have yet to solve all of the problems with their the new turbo V6 Power Unit. After a disastrous Jerez test for the French engine supplier and its partners – most notably World Champions Red Bull – Renault appeared to have taken a step forward when it was claimed that the new Lotus E22 had run almost trouble-free during its more recent track debut. But another Renault-powered car, the 2014 Toro Rosso, has been back in action since the Lotus debut for a similar ‘Promotional Event’, allowed under the regulations for filming and marketing purposes with non-competitive Pirelli tyres. Daniil Kvyat with engineer However reports have filtered through the cordon of security at Misano where the run took place, that the Toro Rosso STR9 with Daniil Kvyat at the wheel managed only 70 kilometres of the 100 km allowed. Rain also interfered with proceedings on the day. According to reports in Italy the running was littered with repeated stoppages for battery and software faults similar to those experienced at Jerez late last month, with the Russian teenager way off the pace of previous F1 testing times at the venue last year. Toro Rosso ditched Ferrari power, which they used until last year, and signed up to be powered by Renault in line with sister team Red Bull, who also were plagued with problems during testing at Jerez. The second phase of 2014 pre-season Formula 1 testing resumes at Bahrain International Circuit on 19 February and will run for four days. (GMM) Subbed by AJN.
