Ferrari is pushing ahead with improving its turbo V6 engine and car after a faltering start to the new era in F1.
Of the sport's three engine makers in 2014, the fabled Maranello marque was the only one not to win a single grand prix.
"F1 must be the ultimate expression of automotive technology," said new Ferrari president Sergio Marchionne recently, according to Italy's Omnicorse.
"So I hope that we are able to realise more powerful engines on the track but without jumping into the void of further driving up costs," he added.
But Omnicorse said a team of AVL engineers is already hard at work at Maranello.
La Gazzetta dello Sport said the latest developments follow the radical shakeup at Ferrari, after Marchionne reportedly analysed the 2015 project and concluded as late as October that it was too similar to the failed 2014 car.
The report said the 2015 car is therefore unlikely to feature the familiar 'vacuum cleaner' nose of this year and will instead more closely resemble the front of the Red Bull.
And his 2015 teammate Kimi Raikkonen was a conspicuous under-performer with Ferrari's last car.
"Kimi has an incredible feel for the front of the car," his former Lotus teammate Romain Grosjean is quoted by Speed Week, "but it was not possible (for him) with the 2014 tyres."
