Ferrari has given fans a first hint about how the sound of Formula 1's new engines may differ in 2016, after releasing audio of its new car fire-up from earlier this week.
On Thursday, the team released a short audio clip of the engine being brought to life, even though it was not revved high at all.
However, with new exhaust regulations being introduced this year to improve the sound of the power units, the throatier sound has offered some hope that F1 cars will be louder this season.
But fans and media will likely have to wait until the first time an F1 car runs in anger to understand the true impact of the new rules, which force teams to run an extra pipe or two from their turbo wastegate.
It is hard to judge the full impact of the new exhaust regulations on engine sound when a car in inside a building because of the acoustic impact of a confined space.
Ferrari is targeting a full-on assault of the F1 championship this year and is believed to have completed a radical overhaul of its power unit to take on the dominant Mercedes team.
