Technical focus: 2016 F1 power units



Renault has stuck to a rather traditional architecture for its latest power unit specification. The compressor and turbine are still side-by-side, with the turbocharger forming a tight package at the back of the engine. Unlike Mercedes, the front of the engine is devoid of any component involved in the charging process.

While we have yet to be provided with detailed pictures of the new Renault unit, one can already notice that the inlet plenum has a rounder shape as if it had been hastily adapted to the already designed Lotus chassis. It is worth noticing that engine integration is not identical from Renault’s works outfit to customer team Red Bull. The ducts that are routing compressed air to and from the intercooler are placed differently (see red arrows). Finally, in the wake of the new-for-2016 exhaust regulations, the R.S.16 only has one extra tailpipe for the wastegate when there are two on the RB12 (compare yellow arrows).
