New F1 engines ‘approaching aerospace technology’ – Renault

Leave a comment

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.

Michael Andretti looking forward to new Australian Supercars venture

If it seems like Michael Andretti is out to conquer the world, he is – kind of.

The former IndyCar star turned prolific team owner has won three of the last four Indianapolis 500s and five overall, second only to Roger Penske’s 16 Indy 500 triumphs.

Along the way, in addition to expanding his own IndyCar and Indy Lights operation, the son of Mario Andretti and the primary shareholder of Andretti Autosport has also branched out into Global RallyCross and Formula E racing in recent years.

And now, Andretti has further expanded his brand internationally, following Penske to the world down under — as in the world of Australian V8 Supercars.

Andretti has teamed with Supercars team owner Ryan Walkinshaw, along with veteran motorsports marketer and executive director of McLaren Technology Group and United Autosports owner and chairman, Zak Brown.

Together, the three have formed Walkinshaw Andretti United, based in suburban Melbourne, Australia. The new team kicks off the new season with the Adelaide 500 from March 1-4.

“It’s just extending our brand and putting it out there,” Andretti told NBC Sports. “The Supercars are such a great series.

“It all started with Zach Brown calling me and said ‘You have to talk to Ryan Walkinshaw. He’s got something interesting to talk to you about.’

“We talked and literally in like a half-hour, we said, ‘Let’s figure out how we’re going to make this work.’ And then Zack was like, ‘Hey, what about me?’ And then Zack came in as a partner and it’s cool now that we have the Walkinshaw Andretti United team.

“I’m really excited about that program, the guys at the shop are excited about it, we’ve been doing a lot of things to try and help it because it’s such a cool series and the cars are so cool.

“I went down there to Bathurst, which was to me one of the coolest tracks in the world. I wish I could have driven it, I really do. It looks like a blast.

“It’s amazing how big that series is when you go down there. It’s one of the biggest sports in Australia. It was just a great opportunity for us to extend our portfolio.”

Admittedly, Andretti had some extra incentive to want to get involved in the Supercars world: Penske joined forces with legendary Dick Johnson Racing in September 2014.

The organization came together quickly and the rebranded DJR Team Penske went on to win the 2017 V8 Supercars championship.

“Roger was down there the last few years,” Andretti said, adding that fact as incentive to get his own organization into the series. “So it’s cool to go race head-to-head with Roger. That was also in the back of our minds.”

This is no start-up venture for Andretti. The roots of the new venture began in 1990 as the Holden Racing Team, which went on to become one of the most successful organizations in Australian V8 Supercar racing, having won the drivers’ championship six times and the Virgin Australia Supercars Championship’s top race, the Bathurst 1000 (essentially Australia’s version of the Indy 500), seven times.

Last season, Holden Racing team morphed into Triple Eight Race Engineering and was renamed Mobil 1 HSV Racing.

And now the company has been renamed once again for the 2018 campaign under the Walkinshaw Andretti United banner.

The team will be composed of two Holden ZB Commodores with drivers James Courtney and Scott Pye, as well as a Porsche 911 GT3-R in the Australian GT championship.

What’s next for Andretti’s motorsports portfolio? Right now, it’s pretty full, but you can bet running for championships from Australia (Supercars) to globally (GRC) to Indianapolis (Indy 500) to the U.S. (Verizon IndyCar Series) are at the top of this year’s list.
