Force India, Toro Rosso and Mercedes shakedown new cars 25 January, 2014 Three of the all new, V6 turbo powered Formula 1 cars got some early track action on Friday, ahead of the first preseason test at Jerez starting on 28 January. One of them can even be heard, after Mercedes released audio of Nico Rosberg speeding past at the wheel of the as yet unlaunched W05 for a ‘filming day’ at Silverstone. Also running at Silverstone was the locally-based Force India’s VJM07, with Nico Hulkenberg at the wheel, while both of Toro Rosso’s drivers were running in the newly Renault-powered STR9 at Misano in Italy. Audio clips of the V6 engines on test benches had raised alarm bells among some Formula 1 fans, but the new Mercedes clip – where the turbo whistle could be easily heard – was warmly welcomed. “You guys had scared me with the sound of that engine test you posted last year,” one commenter wrote, “but once [on] the track it sounds wonderful.” McLaren’s Jenson Button agrees: “From what I’ve heard it still sounds pretty good. “It’s a real mix of sounds because you’ve got the turbo, so it’s quite an unusual sound. But I like it, it sounds good.” (GMM) Subbed by AJN. Content on GrandPrix247.com by: staff & contributors, Reuters syndication, GMM service, Getty Images, Formula 1 teams, sponsors & organisations.
