Mercedes would also prefer for the new engines to be turbocharged but is not as trenchant on the idea as Audi.

Ben Sulayem said in an Instagram post this week that he wants V8s to return because they are “lighter, cheaper, safer and louder”.

His idea is effectively a return to the engine regulations F1 last had in 2013 before turbo hybrid engines made their debut in 2014.

The post said: “V8s are lighter, simpler and more cost-effective, while sustainable fuels mean they can remain aligned with our environmental ambitions. Most importantly, they bring back the unique, visceral sound that fans around the world associate with Formula 1.”

No significant research has been undertaken on the topic of whether audiences do want louder engines to return to F1.

An article on BBC Sport on the topic of F1’s future engines last month contained a poll that received 26,000 responses.

The single biggest vote was for a V8 or V6 turbo engine with 30% hybrid capacity, and there was a clear majority for a turbo engine with significant hybrid capability.

Audi has proposed to the FIA that F1 could use a V8 twin turbo engine with a so-called “hot V”, where the turbos are contained within the two cylinder banks.

This is exactly the engine used in a new hypercar Audi launched on Thursday in Antibes near Monaco. The Nuvolari has a four-litre twin turbo engine with 30% hybrid capacity.

Dollner said: “The Nuvolari has a V8 so we don’t have problems with V8 engines. You have to see that in the overall context. So to just pick one question of a regulation is not really answering the overall question, ‘where do you want to go with the regulation?'”

Asked whether there were any deal breakers with regard to the new rules that could threaten Audi’s participation in F1, Dollner said: “No, not right now. As I think and believe and trust that we will have a good discussion regarding the regulation and we will definitely have sustainable fuels.

“That’s not a topic under discussion and it’s more in some areas a philosophical question, but let’s see what the process brings.”

The FIA has the power to impose engine rules for 2031 because the contracts that bind the teams to F1 and the FIA expire after 2030.

But doing so would risk losing manufacturers at a time when the current hybrid rules – which everyone in the sport accepts are flawed and need refining – have attracted General Motors and Ford as well as Audi, and persuaded Honda to reverse a decision to leave.

Plans for a new tranche of upgrades for U.S. Army special operations MH-60M Black Hawk helicopters are heavily tied to continued progress, or lack thereof, on an improved engine. Work on the Army’s Improved Turbine Engine Program (ITEP) is ongoing now, but there have also been threats to cancel it entirely in recent years, and its future remains murky.

Officials from U.S. Special Operations Command (SOCOM) talked about the intersection of future plans for the MH-60M fleet and ITEP during a roundtable at the annual SOF Week conference yesterday. TWZ was in attendance, along with other outlets. The Army’s elite 160th Special Operations Aviation Regiment, also known as the Night Stalkers, operates the MH-60Ms.

The Army selected General Electric’s (GE) T901 as the winner of the ITEP competition in 2019. The engine remains in development, with flight testing involving a modified Black Hawk beginning in May 2025.

“We are following very closely what the Army is doing with ITEP. We are hoping that we will get it,” Lt. Col. Aron Hauquitz, head of the Technology Applications Program Office (TAPO), said at the roundtable yesterday. “We’ll be able to put it in our aircraft, and we’ll create the Block 2 variant of the MH-60M.”

In “FY30 [Fiscal Year 2030], we’re going to start either the Block 1.2 or the Block 2” upgrade program for the MH-60M fleet, Lt. Col. Cameron Keogh, the Program Manager for the MH-60 within SOCOM’s Program Executive Office for Rotary Wing (PEO-RW), also said at the roundtable. “It’s going to hinge on what’s going on with the Improved Turbine Engine, the T901 program that the Army’s running. We’re closely following that. If it continues to be successful, we will integrate that engine.”

To take a step back quickly, Night Stalker Black Hawks today already have an array of unique features compared to other H-60 variants in service elsewhere across the U.S. military and globally. This includes a terrain-following/terrain avoidance radar and other sensors, a variety of defensive systems, and an extensive communications suite, which you can read about in more detail here. A subset of the MH-60Ms are also configured as Direct Action Penetrators (DAP), which can be armed with a mix of guns, missiles, launched effects, and rockets to provide organic close air support during missions.

Cramming all of these capabilities on the MH-60Ms also requires significant changes to their core structure, and they are notably heavier than other typical H-60 variants. To account for this, the 160th’s Black Hawks already have YT706 turbine engines that are more powerful than the T701s found on standard Army models. GE makes both of these engines.

The YT706 has “higher fuel consumption, but it also has a higher output to help us keep that extra weight in the air,” Lt. Col. Keogh noted yesterday.

Integrating the T901 onto a typical Black Hawk will provide “50 percent more shaft‑power while delivering significantly higher fuel efficiency,” according to Lockheed Martin. Sikorsky, the prime contractor behind the H-60 family of helicopters, became a subsidiary of Lockheed Martin in 2015.

“The 50% power increase means a Black Hawk can transport additional fuel or payloads, such as launched effects, medical evacuation litters, forward area resupply loads or advanced sensor packages, without compromising aircraft performance,” Lockheed Martin highlighted in a press release earlier this month. “The engine’s performance at high altitude, high temperature conditions expands the Black Hawk’s envelope, giving commanders more options for insertion, extraction and reconnaissance missions in austere environments.”

“Higher fuel efficiency and lower maintenance demands lessen the supply chain burden in contested environments, a core tenet of the Army’s continuous transformation strategy,” the press release noted. “Improved specific fuel consumption reduces the number of refuel stops, extending mission endurance and shrinking the fuel footprint in forward operating bases.”

The boost in capability that the T901 is set to bring is especially relevant for Night Stalker MH-60Ms, given their unique attributes and mission requirements. The maintenance and logistics benefits would also be particularly attractive for the 160th. The Regiment routinely flies extremely demanding missions, often conducted across long distances and under adverse conditions, and staged from far-flung locations with limited access to established support chains.

Plans otherwise for the Block 1.2/Block 2.0 MH-60M upgrades are still evolving.

Right now, the core “focus on that is payload restoration. We’re trying to take weight out of the airplane [sic], [and] we’re trying to move the CG, the center of gravity, forward,” Lt. Col. Keogh explained. “How we’re doing that without reducing capabilities is we’re just kind of moving the capabilities around.”

“Somebody asked me earlier if we’re going to take the anti-ice system off the airplane to lose some weight. We’re not. We need the anti-ice, especially up in Washington State,” he continued. “We’re taking some of our heavier boxes, a lot of our avionics, we’re putting them up forward into the crew department, we’re putting them behind the pilots. That’s going to shorten cable runs – copper weighs a lot, you’d be surprised – and then it also helped with our CG shift, as well.”

“That’ll give the operators more butts in seats as they head out to the objective, and also give the air crews better fuel flexibility for mission planning,” he added.

To go back to ITEP, the new engine has long been expected to offer a major leap in performance to regular Army Black Hawks, as well as the service’s AH-64 Apache attack helicopters. However, as noted, the program has faced major uncertainty in recent years. The effort has suffered significant delays tied to manufacturing and supply chain issues. The T901 was also a central component of the Army’s Future Attack Recon Aircraft (FARA) program, which the service axed in 2024.

Last year, there were indications the Army was moving to cancel ITEP, too, with the service requesting no additional funding for the program in its 2026 Fiscal Year budget proposal. Congress subsequently interceded, appropriating another $238 million for continued work on the engine in the current fiscal cycle.

In its 2027 Fiscal Year budget request, the Army is again not asking for any new money for ITEP, which has raised new questions about the program’s future.

T901 First Engine to Test Mission Accomplished

At the Army Aviation Association of America’s (AAAA) 2026 Warfighting Summit last month, Army Maj. Gen. Clair Gill said he was “very excited about where they’re going there” with ITEP and that the engine was “almost nearing completion of certification.” Gill is the service’s Program Acquisition Executive for Maneuver Air.

ITEP is “performing as intended,” and “the resourcing that Congress added in 2025 and the resourcing that Congress added in 2026 is being used to deliberately continue that testing,” Army Brig. Gen. David Phillips also told TWZ and other outlets at a roundtable at the AAAA conference, but did not elaborate on future plans for the engine. Phillips is the Deputy Portfolio Acquisition Executive for Maneuver Air.

“We will need a little bit more money to get through the EMD [engineering, manufacturing and development] program, but it’s certainly not anywhere close to the money that we’ve already received for the program,” Mike Sousa, GE’s Executive Program Manager for the T901, had also told members of the media ahead of the AAAA conference, according to Breaking Defense. “So there is a little bit of money that is still required.”

Another factor now in all of this for the Army, as well as the Night Stalkers, is the expected arrival of the new MV-75 Cheyenne II tiltrotor in the next few years. The MV-75 offers massive boosts in range and speed compared to any Black Hawk variant. At the same time, that is also expected to come at a cost. As it stands now, the MV-75 is not expected to replace all of the Army’s H-60s, which will continue to play important roles for years to come. SOCOM and the 160th have a similar vision when it comes to the fielding of a special operations-specific version of the MV-75 and the future of the MH-60M.

“There will not be a one-for-one swap for MH-60M and MV-75. Don’t ask me what that exact number will be,” Dr. Steven Smith, head of SOCOM’s PEO-RW, also said at the roundtable yesterday. “We’re still going to need analysis to determine what that will be, but it will not be a one-for-one swap. We recognize that the M-60s will be required for the crisis response mission.”

As an aside, the 160th’s MH-60Ms, including examples in the DAP configuration, were a key element of Operation Absolute Resolve to capture Nicolas Maduro, then Venezuela’s dictatorial president, in January. TWZ explored the contributions of the DAP helicopters in detail at the time.

Altogether, the MH-60M is still on track to be a central component of the Night Stalker’s fleets for years to come, whether the helicopters are re-engined in the end or not.

This question essentially centres on the push by FIA president Mohammed Ben Sulayem to return Formula 1 to a set of engine regulations that are pretty much the same as the era from 2010-13.

We delved into this topic extensively last week. There’s a link to that article below.

Now, as to the specific question, yes, 2013 was pretty boring, or at least the second half of it was.

The season started relatively competitively – Red Bull’s Sebastian Vettel won four of the first 10 grands prix, but Ferrari’s Fernando Alonso, Lotus’ Kimi Raikkonen and Mercedes drivers Nico Rosberg and Lewis Hamilton all won over that period.

But a change to the specification of tyres following a series of blow-outs at the British Grand Prix led to Red Bull dominating and Vettel won the last nine races in a row to clinch a fourth consecutive world title.

The last years of the V8 era, once refuelling was banned at the end of 2009, fluctuated between intensely competitive and, er, not.

The 2010 and 2012 seasons had gripping title fights. In 2010 there were five drivers in the running until the penultimate race, and four mathematically at the last one.

That was the year Ferrari dropped the ball on strategy in Abu Dhabi and threw away the title, letting Red Bull and Vettel in to win their first title.

In 2012, there were seven different winners in the first seven races, and the title fight between Vettel and Alonso went to the final race again.

In 2011, as in 2013, Vettel and Red Bull dominated.

But there were a lot more factors involved in those scenarios than just engines. Tyres, for one. The relative competitiveness of the cars for another.

However, the naturally aspirated era – and especially the years from 1994-2009 when there was refuelling – was notorious for the lack of overtaking on track.

That has certainly increased this year with the new style of “yo-yo racing” brought about by the new hybrid engines.

There are so many issues wrapped up in this engine debate. Some of it may well be people harking back to the past, one they felt was more attractive than what F1 serves up today.

But there is also a cost issue, whether the essence of F1 has been polluted, noise, the changing road-car market place and on and on.
