Details about the specification of Formula 1's alternative engine for 2017 has emerged.
Previously, it was believed independent outfits like Ilmor or Cosworth were being invited to bid to exclusively supply a 2.2 litre twin-turbo V6, with the regulations to run parallel to the existing 1.6 litre 'power units'.
The specifications now say the new engine will be a 2.5 litre V6 or smaller, with one or two turbochargers producing "greater than" 640kW.
No hybrid power?
The engine will have no limits on revs, engine durability or fuel flow, freedom in the area of the exhaust and no hybrid power.
Mercedes, the double world champion team of 2014 and 2015, has made clear its dissent.
Team boss Toto Wolff said: "I think many of us share the opinion that the 'balance of performance engine' does not work. It doesn't work in any other category.
"We hear about the aggravation in GT racing and it does my head in hearing these ideas," he added.
