Superleague Formula test driver Bruce Jouanny is fast racing into view as I stand on the pitwall at Circuit Monteblanco. Series competitions director Robin Webb hands me some earplugs. "You will need these," he shouts with an urgency that tells me that, although I hardly ever bother to wear them, even at a grand prix, maybe now is the time to change my habit.
With all background sound now blocked out, Jouanny changes up to sixth as he flashes by. You don't just appreciate the audio attack - there is still that unmistakable wail, despite the earplugs' best efforts to drown it out - but you also feel the power of the V12 as the ground shakes beneath you.
Webb is watching on proudly as his new baby, the 750bhp Panoz-MCT, zaps past us onto another voyage of discovery in its development programme. "And that's just one of them - imagine what 20 will sound like," he enthuses. "It's taken a lot of work to get here but, boy, does that noise make it worth it!"
