New F1 engines ‘approaching aerospace technology’ – Renault

Renault were at the forefront of F1’s last turbo era, leading the way by introducing a 1.5-litre turbocharged engine in 1977 at a time when all the other teams were using normally-aspirated power units.

Within a few years F1 had tapped the enormous power of turbocharged engines and Renault won a string of races, although they failed to clinch a championship.

Turbo power was outlawed at the end of 1988 but will return to F1 next year. Renault’s director of testing and development Jean-Pierre Menrath, who worked on the original Renault turbos of 1977, explained how the technology has moved on since then:

“The major difference, of course, and the major technological development on the new engine, is in the electronics,” he said. “We started developing a turbocharged engine with distributors and igniters, which are no longer in use today. The fuel injection system had no electronics.”

“And in terms of design, the modern simulation tools didn’t exist back then, nor did all the computer systems and software used to design the engines more effectively and track their performance more accurately.

“There was no telemetry, no data acquisition. For the record, the driver could alter the booster pressure. Our “telltale” was a dial with a needle that was stuck pointing up. So, at the end of the day, the level of monitoring was somewhat limited.

“Nowadays, engine technology is a lot more effective. We’re very close to the complex systems used in aerospace.”

Towards the end of the development of the old turbo engines Renault saw some astronomical power outputs: “We went from 520/530bhp in 1979 to over 1,000bhp in the space of five years!”

“At the end of 1986, we even had a test engine that was capable of developing up to 1,200bhp thanks to the use of new turbochargers, with a new design. At the outset, they were intended to be used at altitude and in the end, at sea level, they produced exceptional performances. Unfortunately, the engine only lasted three laps!”

Renault anticipate next year’s engine, dubbed F1 Energy, will produce around 600bhp with a further 160bhp coming from the electrical energy recovery systems.

Santino Ferrucci will drive No. 14 for AJ Foyt Racing full time in 2023 IndyCar season

Santino Ferrucci will return to full-time racing in the NTT IndyCar Series next season, joining AJ Foyt Racing.

Ferrucci had made eight IndyCar starts with three teams since his last full-time season in 2020 while also racing part time in the NASCAR Xfinity Series this year.

He will drive the storied No. 14 Dallara-Chevrolet for four-time Indy 500 winner A.J. Foyt’s team, which will field the car from its Waller, Texas headquarters.

“It’s incredibly exciting to be back in the INDYCAR Series full time,” Ferrucci said in a team release. “Being a part-time driver over the last two years has been hard for me, personally. I’m a race car driver, and I want to compete. Working with different teams has been exciting, and I’m proud that no matter which car I’ve raced, I’ve always shown speed and consistency. I couldn’t be more excited to join AJ Foyt Racing in the 14 Chevy. I can’t wait to make the best of it.”

Ferrucci, 24, had finished a career-best fourth in IndyCar four times, including the 104th Indy 500 in 2020. He was the 2019 Indy 500 rookie of the year with a sixth.

In nine Xfinity starts since 2021, Ferrucci has a career-best finish of 13th at Las Vegas Motor Speedway.

“I am thrilled to welcome Santino to the team,” Larry Foyt said in a release. “He’s shown a knack for getting toward the front of the field, and I think he is a racer who moves forward on race day. A.J. sees the fire in him and has enjoyed their meetings together. I think Santino’s experience will help his rookie teammate as well, so he is a great addition to our roster.”

Ferrucci will be teamed at AJ Foyt Racing with Benjamin Pedersen, who finished fifth in the 2022 Indy Lights standings. The team has yet to specify the number for Pedersen’s entry, which will be fielded out of its Indianapolis race shop.

Foyt’s two full-time drivers last season were Dalton Kellett and Kyle Kirkwood, who is moving to Andretti Autosport.
