New engine rules spur the interest of four engine manufacturers

Slowly but surely, Formula 1's new engine rules set for introduction in 2021 are drawing interest from outside manufacturers and independent engine makers.

According to the BBC, Ilmor and Cosworth, which in the past, long before the sport ushered in its hybrid era, were both heavily involved in F1, are watching developments closely.

"The current regulation is beyond any new entrant, technically and for the commercial investment it requires," Cosworth chief Bruce Wood told the BBC.

"The new proposal makes it possible for an independent or existing car company."

McLaren focused on Renault performance not reliability issues

Steve Miller, managing director of Ilmor, added: "[The new regulations] open the scope to a much broader range of manufacturers."

Formula 1 is opting for a simplified engine platform from 2021, with the removal of the MGU-H element, which in theory should lower productions costs.

While the move is a step in the right direction, both Ilmor and Cosworth would still require outside funding to develop their own power units.

Red Bull partner Aston Martin is also eyeing the post-2020 engine rules, and Germany's Auto Bild claims that Porsche could enter the sport as well.

But retired Porsche sports car driver Mark Webber does not believe this will happen anytiome soon.

"Porsche in Formula ? It will not happen," said the Aussie.

As for McLaren boss Zak Brown, he admitted he hopes the 2021 rules succeed in tempting more engine makers into the sport.

"It would be great to have an independent engine or two, so that if you aren't in a situation where you have a manufacturer, you still have economical and yet still competitive options," he said.

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.
