Renault’s Taffin: Fuel consumption could well be an issue in Singapore

1 Comment

The new fuel consumption numbers for Formula One this year were in the news right from the get-go in Melbourne. Daniel Ricciardo’s disqualification for exceeding the maximum limit was arguably the biggest talking point leaving the event.

While the fuel flow discussion has gone down since, it could well be a major issue in Singapore this weekend. At 61 laps and usually a race time close to two hours, Singapore presents one of the longest races of the season and the fuel numbers will really need to be managed.

Remi Taffin, Renault F1’s head of track operations, explains how challenging this will be for teams to master:

“The ICE and turbo are therefore given an easy time here. The Energy Store and MGU-K, however, are really put through their paces,” he said in an advance release. “Each braking event is long and hard, particularly around the ‘hotel’ section through the grandstands, where the K will be able to recover enough energy to keep the battery at a relatively high level of charge throughout the lap. In contrast, the MGU-H is used a little less as the short straights between the corners do not really offer ample time for the exhaust to develop a steady flow.

“These short bursts of power naturally require good torque response and driveability but they also bring fuel consumption well up. In fact we will use the largest amount of fuel per lap over the season here and we will be right on the limit of the 100kg permitted. To put this in context, last year we used 150kg of fuel – over 30% more. Here, more than anywhere else, shows the advances we have made in efficiency.”

With the Renault’s lack of power by comparison to Mercedes one of the notes of the year, Renault is confident it should be better at this circuit, as it requires less time at full throttle (roughly 45% of a lap).

“Singapore should suit the Renault Energy F1-2014 far more than the previous two tracks. We’ve made good progress in energy recovery and management and these two elements are key to success here,” he said.

ANAHEIM, California – Ken Roczen will make the move from HRC Honda to H.E.P. Motorsports with the Progressive Ecstar Suzuki team, ending a long and eventful offseason that saw his split from his longstanding team after he committed to running World Supercross (WSX).

“H.E.P. Motorsports is thrilled to announce that the team has signed Ken Roczen as its premier rider for the 2023 season,” the team announced on Instagram. “Former AMA Motocross champion Roczen will be aboard a Suzuki RM-Z450. Roczen, who won his most recent championship on a Suzuki, will be reunited with the brand and bring his exciting style, determination, and grit back to the RM Army.

“Ken Roczen will compete in the upcoming 2023 Supercross and Motocross Championship series which is set to start on January 7 at Anaheim Stadium in Southern California.”

For Roczen, it is a return to the bike of his youth and on which he had some of his greatest professional success.

“This thing has been going on for weeks and weeks and weeks in the making, but there was so much uncertainty,” Roczen told NBC Sports during Monster Energy Supercross Media Sessions. “It was a very unique situation. I just finally signed two nights ago, so it’s really only legit once the ink hits the paper. It’s been in the works for a long time, but there were just a lot of questions and a lot of input from a lot of other teams too.

“Good things take time, and I’m okay with that. I grew up riding Suzuki. Ot’s like a homecoming. It’s a special feeling”

Roczen won the 2016 Lucas Oil Pro Motocross Championship on a Suzuki before making the move to Honda. That year he won nine of 12 Nationals and finished no worse than second as he easily outpaced Eli Tomac by 86 points. He finished third in his next Pro Motocross outing in 2018 after sitting out the outdoor season in 2017.

“I am beyond excited to reconnect with Suzuki for the 3rd time in my career. We’ve had a lot of success in the past and I’m looking forward to seeing what we can accomplish together in our future.” Roczen said in the Instagram post.
