Nico Rosberg will use the same new-specification Mercedes engine, removed from his car ahead of qualifying at Monza, for the 2015 Singapore GP.
That is the claim of Auto Motor und Sport, as new details about Mercedes' upgraded 'power unit' now begin to emerge.
Auto Bild, describes the unit that cost Mercedes all remaining seven of its performance upgrade 'tokens' before Monza as a 'Wundermotor'.
Fuel test for Merc?
Team boss Toto Wolff said: "It brings not so much more horse power but it works more efficiently. We wanted something to test in connection with a new fuel for 2016."
However, although Lewis Hamilton went on to win at Monza, and some rivals sensed the potential of the new engine is "scary", Rosberg's unit was removed before qualifying amid reliability concerns.
Auto Motor und Sport claims the very same unit will now be raced by the German driver in Singapore, after post-Monza investigations showed that the power unit itself was undamaged.
Rosberg said: "It turns out it (the problem) had nothing to do with the engine. It was a chassis component that we've had on the car for a long time.
"So with hindsight, it was perfectly ok to put the new engine in."
The report said Mercedes will now be preparing the engine specification for customers Williams, Lotus and Force India to use at subsequent races if they desire.
Auto Bild said the specification is fundamentally different from its predecessor, as it features an "innovative, fuel-efficient combustion process".
So after a miserable weekend of reliability at Monza, Rosberg is hoping for smoother sailing this weekend.
A new complication, however, is the pollution-filled skies above Singapore, potentially worsening what was already a tough race physically for the drivers.
Rosberg is quoted by the German broadcaster RTL: "That (the air quality) makes it even harder for us, and perhaps also for the cars,"
