Porsche interested in F1 slot in 2021

Porsche may be tempted into Formula 1 when the sport's engine and financial regulations change in 2021. Aston Martin has also suggested that the "simpler, cheaper" power units promised by Liberty Media are of interest, despite the complaints of existing giants Mercedes and Ferrari.

Ferrari CEO Sergio Marchionne has threatened to pull the Scuderia out of F1 if Liberty press ahead with regulation changes, which he has claimed will alter the "DNA" of the sport.

Meanwhile, Mercedes team principal Toto Wolff says a proposed cost cap of $150million per year is unachievable for engine suppliers such as the Silver Arrows.

An F1 statement released this week confirmed that the costly and complex MGU-H exhaust energy recovery system will be removed.

Former F1 driver Gerhard Berger, now the promoter of Germany's DTM touring cars championship, believes that Porsche could be interested in F1, which may strengthen Liberty's hand as more lavish brands come into play.

"Porsche is thinking about a Formula 1 entry from 2021," Berger told Autobild.

"They are waiting for the new engine regulations, which should be adopted in May, and will then decide."

Porsche previously competed as a team in F1 between 1957 and 1962. Their best finish was third place in the 1961 standings, with American racing legend Dan Gurney taking three second-place finishes.

Aston Martin president and CEO Andy Palmer was quick to confirm the sports car manufacturer's interest in an F1 entry after Liberty revealed an outline of their future vision at the Bahrain Grand Prix.

We are extremely pleased to hear today’s news regarding the future of Formula One. These prospective changes support many of the requirements needed for Aston Martin to enter the sport as an engine supplier. This is a very positive step in the right direction. — Andy Palmer (@AndyatAston) April 6, 2018
