2017 engine to be 2.5 litre twin-turbo V6

Nov.17 - Details about the specification of F1's alternative engine for 2017 have 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" 870 horse 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.

"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," said team boss Toto Wolff.

"We hear about the aggravation in GT racing and it does my head in hearing these ideas," he added.
