The date and location of Valentino Rossi's return to a Ferrari F1 car has now been confirmed as November 20-21 at Mugello.
The outing, which Rossi insists is purely for fun, will mark the newly crowned six-time MotoGP world champion's first F1 drive since an impressive performance at Valencia in February 2006.
The Valencia test was Rossi's fourth in a Ferrari Formula One car, but his first with other teams and drivers present - after private sessions held at Fiorano and Mugello.
Rossi finished the Valencia test twelfth and within 1.5sec of fastest man - and reigning F1 champion - Fernando Alonso (Renault). Rossi's best lap was just 0.711secs from fellow Ferrari driver Michael Schumacher.
However, direct comparisons were difficult because most drivers were using the new-for-2006 2.4 litre V8 engines, while Rossi was given a 3 litre V10 engine "limited to reproduce the conditions set out in the 2006 regulations". Rossi's chassis was also of an older design.
The only other driver thought to have been using a V10 engine was McLaren test driver Pedro de la Rosa - and Rossi outpaced the experienced Spaniard by 0.095sec, despite several spins.
Speculation that Rossi would quit MotoGP for F1 reached fever pitch in the weeks and months that followed, but the #46 committed his future to MotoGP on the eve of his home Italian Grand Prix - also at Mugello - in early June of that year.
Rossi now has a Yamaha MotoGP contract in place until the end of the 2010 season, by which time he will be 31-years-old.
