Alain Prost: F1 2014 engine reliability problems inevitable

Alain Prost believes all three engine manufacturers will suffer from unreliability at the start of the 2014 Formula 1 season, when the new 1.6-litre turbocharged V6 regulations are introduced.

The four-times world champion expects Renault, for which he is an ambassador, Mercedes and Ferrari all to hit reliability problems because of the demands of the new technology.

But it will not be until pre-season testing starts in late January that the extent of the problems, if any, manifest themselves.

"I can tell you, for sure we are going to have some reliability problems, in the beginning especially," Prost told AUTOSPORT.

"We will see if it is only in private testing in the winter, but nobody knows at the moment.

"In a way it's good because we are at the beginning with this technology, like we had with the turbos [in the 1970s and 80s].

"We all need to accept that sometimes it is going to be a problem.

"Reliability is always an issue. It's an issue because you have the engine and the turbo, but there are electrical parts, wires, different systems.

"Even if everything is OK, you then have the integration with the car and different aspects like temperature and vibration."

Prost insists it is important for F1 and the fans to accept the early teething problems.

He believes that, in the long-term, the fans will find the performance variations between the various engines an interesting storyline, which will also boost the profile of the manufacturers.

"We all need to accept that sometimes it is going to be a problem," said Prost.

"The public will understand it is a new technology and it is not reliable, but slowly they will see that you get the performance, the reliability, the fuel consumption.

"It's very good for the automobile industry and the three, or maybe four [when Honda joins in 2015] constructors.

"I remember the way we were in the 80s when Renault didn't have a good image and then F1 helped them very much."

Although he does not expect reliability to be perfect at first, Prost underlined that Renault is on target with work on its new engine.

While Renault has a clear idea of the overall performance of its engine thanks to dyno work, he expects performance to continue to improve.

"Everything is on target, everything is OK," said Prost.

"Everybody is very cautious about what they do and what they say because it is a completely new technology.

"Performance, more or less, we are going to know where we are so it is going to make a progression slowly."

I just hope the fans will understand this, and it will take awhile to work out all the bugs? This new technology will be well worth it though.

Many things have been talked about with heat recovery, no decent results yet though.
Options considered are:
1 / TEG's, Seebeck effect, the reverse to Peltier and the two types of cells are not interchangable, Seebeck creates a current through a temperature differential, while Peltiers create a temp differential when a current is supplied, either way low efficiency.
2 / Sterling engines, as mentioned, but very bulky for power supplied.
3 / Steam generation for steam turbine/engine, again heavy and bulky
4 / Heat ejection in rear to energise air in rear void, idea is if you increase temp, you increase pressure and reduce drag, this is my favorite at the moment, but how to get the heat out there?

The F1 thing is great but they're already anticipating teething issues with Billions spent, so unlikely ecomodders can do it with $50.
