Renault Sport F1 boss Cyril Abiteboul admits that Honda's recent progress has kept him up at night, the French manager believing the Japanese manufacturer is spending massively to catch up with its rivals.

Honda's power unit has undeniably made great strides this season, both in terms of performance and reliability, its most recent upgrades likely putting the engine just shy of Renault's unit.

"Frankly I'm worried about everything in life, but in particular about a situation on the engine side," said Abiteboul.

"As we've seen since last year, Honda is making big steps, big gains.

"Red Bull has been very clear that they are investing massively, and apparently much more than us."

Abiteboul defended however Renault's own work, expressing his confidence in the future and underlining the fact that it had an entire package to contend with, not just an engine.

"We are happy for Red Bull and Honda but frankly we have our way to do things," he added.

"We have a plan and we are executing that plan. It's not just about an arms race."

"We have all the aspects of the package to develop. No one is providing anything to us, either in the powertrain or on the chassis, so it has to be step by step.

"We are very confident in our upgrade for next year. We want to play the long game."

However, Renault's 2019 engine won't be a mere upgrade of its current unit, according to Abitboul.

"Given the ambition in terms of power improvement for next year, pretty much all of the engine will be new," Abiteboul told Motorsport.com.

"Not only on ERS side, because there is little power and little performance to extract there, but the rest of the ICE will be new.

"That is why we need to be a little bit careful and that is why we need to be extremely drastic and have lots of discipline on planning and milestones to make sure that we are not putting ourselves in a difficult position at the start of the season."

So far, the unit's development has gone according to plan at Viry-Châtillon.

"We are well advanced on the dyno, we have covered lots of mileage on the dyno," he added.

"We had two parts which were a problem this year, the turbocharger and the MGU-K. With the MGU-K, we are running, we have not had any problems so far and we haven’t seen any, either on the dyno or on the track.

"The last spec of turbos seem okay too, but they are not on all cars because of the situation where parts introduced mean a penalty.

"That is what is silly with the current regulations, even if you have a better part you cannot afford to introduce it because of all the penalties and all the sporting consequences. That is crazy.

"You are spending money to improve your parts, you approve it on dyno, it is available it is built, it is there [at the track], and you cannot put it on the car.

"That is crazy. There is really something wrong here. But anyway, that is why – those two issues are addressed."

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
