D he fronts in the engine dispute are hardened. Mercedes has withdrawn its compromise offer of five additional tokens with an extension of the development time until the end of April. Ferrari and Renault wanted 13 extra tokens and a homologation period by the end of July. This means that everything will remain the same in 2015.

The engine manufacturers are allowed to use 32 tokens for their modifications, which corresponds to 48 percent of the engine. The final stage of development of the engines has to be sealed on February 28th.

In the meantime, it has transpired that the number of tokens is not the big problem. It is the time. Neither Ferrari nor Renault will be able to use the 32 tokens until February 28th. Because they started developing their 2015 engines way too late. Ferrari in July, Renault in August. Niki Lauda shakes her head in astonishment: 'Why not go straight to Melbourne? Both of them already knew they were behind.'

Mercedes F1 engines with a lead again in 2015

Not all knowledge is the same. First you have to recognize your own mistakes and then have a brilliant idea of ​​how you could do it better. Apparently Renault and Ferrari are technically so far away from the Mercedes engine that it is impossible to make up for the gap in a year. Not even when Mercedes puts its hands on its lap.

Renault has to work on the basic concept of the V6 turbo. It vibrates too much. The exhaust manifolds swing by up to three centimeters, which increases the space required in the rear. It's a miracle that the Red Bull can still build extremely slim at the rear.

The exhaust pipes are far too long. This conserves too little heat and energy for the MGU-H. The engine needs significant changes to the cylinder head and injection to improve combustion. The goal is to ignite as early as possible without reaching the knock limit. Mercedes can do that much better. The result: more power with less fuel consumption.

Renault is not copying Mercedes-Turbo-Trick

engine pope Mario Illien helps Renault solve the engine's mechanical problems. The Swiss are familiar with turbo engines. He has been building them for the IndyCar series since the 1980s. His hands are tied on one point. Renault has to put the separation of compressor and turbine on the back burner after the Mercedes model.Due to time constraints. It's a complicated procedure that requires a lot of fine-tuning. It took Mercedes a year to present the solution firmly.

The advantage of the spatial separation at the two engine ends is that the charge air arrives at the compressor much colder and does not have to be cooled down as much there. This allows more efficient combustion and increases efficiency.

Ferrari is said to have this measure in its program for 2015. Why Renault jumped on the train so late is incomprehensible. The first photos of the turbocharger architecture were already wandering around the net after the Australian GP.

But Renault engineers said at the Spanish GP that they did not consider this trick to be a match winner. Mercedes engine boss Andy Cowell confirmed it: 'It's not the magic key to our concept. In our engine there are probably 100 things that are different from Ferrari and Renault.' Maybe Cowell deliberately scattered fog there.
