The opening day of F1 pre-season testing in southern Spain didn't just prove frustrating to those teams attempting to progress the development of their 2014 steeds, but also for anyone hoping to grow accustomed to the sound of the new V6 engines.

Mandated in a wholesale technical overhaul, the turbo-charged 1.6-litre powerplants replace the V8 that had served the sport well over the past seven seasons and which, after initial disappointment when they replaced the previous V10s, became accepted as the sound of F1.

Despite the three engine manufacturers - Renault, Mercedes and Ferrari - doing their best to prepare fans for the new aural experience via audio clips posted online over the winter break, it wasn't until the cars took to the track in anger that anyone expected to get a real feel for the new sound.

Sadly, with only around 90 laps completed on an opening day graced by good weather at Jerez, and a lot of those in isolation as teams suffered a series of technical gremlins, there was little chance to get used to the various different noise.

"It's a bit disappointing to be honest," Force India's Nico Hulkenberg said, having watched as new team-mate Sergio Perez conducted the squad's limited running, "It sounds a bit like a DTM car. It's not the same sound as a V8; it's a lot quieter from what I've heard today. Maybe there's more to come, but it's not the old screaming V8 and high rev engine sound."

While Mercedes' Nico Rosberg admitted that the new sound took him back to an old one, the 1980s era in which his father starred, the marque's head of motorsport, Toto Wolff, insisted the opinions would change when the cars were finally given their head.

"You must not forget that what we are doing here is basically a system check and shakedown and once you hear a car on full revs and flat out and more cars," he told Reuters, "I think, in a couple of months, nobody is going to really speak about the old engines and old engine sound."
