Within the rolling hills north of Los Angeles, subsequent door to a film lot, Honda’s American motorsport division HPD has produced among the most potent engines in US motorsport; powerplants which have claimed 18 IndyCar championships and 15 Indianapolis 500 wins, together with a surfeit of sportscar titles and a trio of general Daytona 24 Hours victories for its luxurious Acura marque.
However Honda is a Japanese firm, proper? Guardian firm Honda Motor Co is the multinational conglomerate based mostly out of Tokyo, however the American Honda Motor Firm, based in 1959, has grown into a large concern in its personal proper – not unhealthy from an preliminary workers of three with a start-up funds of simply $250,000 to promote motorbikes!
Primarily based out of Torrance, a number of miles south of Honda Efficiency Growth’s 123,000-square-foot facility in Santa Clarita, it started constructing street vehicles within the US within the 1980s. It’s now one of many top-selling automotive OEMs in a humongous market.
Honda started its US motorsport operations in 1993, becoming a member of the CART Indycar collection as an engine builder (with help from Ilmor) in 1994, after which grew to become a bedrock provider for the Indy Racing League and IndyCar collection, the place it at present provides 15 vehicles in competitors with Chevrolet (which, satirically, now makes use of Ilmors).
In sportscars, after a Spice-chassised programme within the early 1990s utilizing engines straight from Japan, Acura’s entry into the American Le Mans Collection raised its sport in 2007 – it featured a primary bespoke racing engine constructed fully in-house – starting with an LMP2 class win on the 12 Hours of Sebring.
That very automobile, the Andretti Inexperienced Racing-run ARX-01a piloted by Dario Franchitti, Bryan Herta and Tony Kanaan, resides in a again room at HPD. It’s pointed to by firm president David Salters as the start line to its heritage as a real manufacturing facility sportscar entrant, and that reworked Braveness chassis has led to a agency partnership with its religious successor, ORECA.
In 2023, Acura’s ARX-06 LMDh vehicles have made a quick begin to the IMSA SportsCar Championship, and you possibly can argue that it’s bought the second or third-fastest sportscar prototype on the planet, after the World Endurance Championship’s Toyota and Ferrari. Its profitable begin on the Daytona 24 Hours adopted the three-time championship success of its DPi predecessor and, coupled to its profitable NSX GT3 challenge, Acura has scored over 100 race wins in sportscars.

Salters, who hails from the north-west of England, moved to the US in 2015, after working for Ferrari in Method 1 and, earlier than that, at Mercedes-Benz Excessive Efficiency Engines and Cosworth. He says his time in F1 taught him to “see the way it can work… and can’t work! Some folks had been awfully good – Ross Brawn, what a genius – and I’ve been fortunate sufficient to see lots of various things.”
Of his position right now, Salters explains that HPD works independently of its equal HRC in Japan, however that they convey frequently.
“We reply to the advertising and marketing aspect of the model, and our purpose is to advertise Honda and Acura, and to develop folks and know-how,” he says. “We’re all loopy motorsport folks, we talk nicely collectively, and Honda is a really respectful firm. Racing may be fairly an aggressive setting, however there’s an actual respect for the person inside Honda.

“We do our personal factor, as a result of it’s essential do this to be quick, however we come collectively occasionally. It’d be fairly silly if we spent all this cash and didn’t share the information. The mission right here is completely different to Japan, actually. They go and win F1 world championships, in order that they’re the perfect on the earth. And [Toyoharu] Tanabe-San, the technical director there, used to work right here.”
Honda motorsport supervisor Chuck Schifsky provides: “I feel there are two large misnomers about us – the primary is that this programme is overseen by Japan and that David does all the things they inform him to. He really stories straight to our North American CEO Mr [Noriya] Kaihara.
“The second is that our operation is strictly the identical as Chevy’s, particularly in IndyCar, the place Ilmor is their associate. There’s not one other constructing, with one other title on it, that’s making all of our engine parts for us.”
HPD’s workers stage is working at a file excessive of 250 after, Salters says, “we determined it was an amazing thought to do new IndyCar and present IndyCar, plus DPi and new GTP all on the identical level”, so an additional 100 workers had been successfully introduced onboard in six months.
“4 tasks meant extra firepower, however that quantity will come and go,” he provides.

Our tour of the manufacturing facility begins on the meeting store, the place 20 or extra engines are in varied levels of construct within the bays. One factor jumps out instantly: there are a lot of extra powerplants coated with purple mud jackets (IndyCar items) than blue ones (IMSA items) – a easy, but efficient, manner of avoiding confusion when not being labored on! – and we’ve arrived in mid-April simply because the Indianapolis 500 qualifying motors are being crafted.
Subsequent door is one other big manufacturing room that’s filled with buzzing CNC equipment, the place the engine elements are created. These machines may be programmed to work ‘lights out’ – to make sure 24/7 manufacturing if want be, a lot as you’ll discover within the aerospace trade.
We encounter some neat stuff at each flip as we meander round HPD’s rooms, together with a metallurgy workplace boasting some electro-microscope and evaluation gear that Autosport has solely encountered beforehand at the back of the Ferrari F1 pits. Its pattern testing recognized an issue with IMSA’s new 80% mix of renewable gas for 2023, which led to an oil contamination problem inside its GTP powerplants. After discovering ranges of as much as 20% of gas (a removed from ultimate lubricant) in its oil, HPD discovered a novel answer to an age-old downside.
“We really found a [scientific] paper that was 100 years previous,” says Salters. “All these years in the past, a bunch at a college had modelled the equilibrium standing of how gas and oil work together. So, we did a great deal of classical sums and we had been ready to make use of that previous paper with 21st century measuring gear, and we had been ready to determine how the oil and gas would attain an equilibrium state.”
A brief-term repair led to a 1-2 end within the Daytona 24 Hours, and it has since “accomplished the engineering, so now it’s more-or-less underneath management”.
The actual mindblower of this facility is seeing the dynamometer cells, the place all of the engines are examined to make sure their efficiency ranges. One of many Indy 500 items is revving flat-out on a qualifying simulation, and it’s an superior sight to see the exhausts glowing brightly on the opposite aspect of the window. “How scorching are they working?” we ask. “950C,” is the matter-of-fact reply.
But it surely’s not simply proving out the present equipment; there are particular dynos for analysis and growth, together with a neat single-cylinder set-up that includes all types of measuring gear. We will even see contained in the cylinder, because it fires, through a tiny digital camera linked to the plethora of screens exterior.
The most effective is but to return: a transient dyno that not solely exams the engine however the gearbox and the power retailer. That is the place HPD can trial the enterprise finish of its automobile on a digital race observe, even simulating the air strain into the engine and its bodily responses to being pushed round… whereas fully stationary! As we speak it’s an IndyCar V6 that’s being developed for the collection’ 2024 hybrid period, when supercapacitors will give a 100bhp enhance.

There’s additionally a high-voltage battery lab, and a refrigerator-sized dSPACE simulator that’s hooked up to the F1-spec GTP ECU. That is consistently being put via its paces, with three full-time coders engaged on updates for the open-software IMSA hybrid management system.
Upstairs, in an ethereal nook of the places of work, is its mission management for the GTP programme. Banks of giant screens are located in entrance of a number of workstations, the place distant engineers help these on the observe. As we speak, there’s a take a look at session working at HPD’s simulator in Indianapolis, the place we are able to see Filipe Albuquerque behind the wheel of the full-motion rig that’s working the digital ARX-06 at Lengthy Seaside. In a aspect room at HPD, IMSA racer Matt McMurry is a part of this course of, and has his personal static simulator that runs the identical rFactor2 software program.
“It’s predictive simulation,” says Salters. “This automobile has by no means run at Lengthy Seaside, however we all know the way it carried out at Daytona and Sebring, so it’s about correlating the mannequin of the automobile and tyres with information from the observe.”
“It’s not rocket science, it’s about getting the best folks in the best locations with good power, to push in the best course” David Salters
It’s simply one other instance of the wonderful stage of know-how to energy success on the elite stage of American motorsport, however Salters is eager to level out that the equipment is nothing with out the individuals who use it.
“It’s all about these girls and boys who work right here, so it’s good you bought to see them at their work to indicate you what it’s all about,” he says. “It’s not rocket science, it’s about getting the best folks in the best locations with good power, to push in the best course. That’s once you obtain loads. All the remainder is simply fluff!”
Seeking to the long run, HPD’s programmes are set in IndyCar, with the hybrid period kicking off subsequent yr, and IMSA GTP. After the Lengthy Seaside GP, the highest brass of American Honda and Acura met for a future technique dialogue. They checked out two years out, however time was put aside for 5 or 10 years therefore, and Salters and Schifsky additionally bought a steer from an advisory board that guides them on the course of Honda and Acura as automotive manufacturers.
“It’s an amazing dialogue of HPD asking, ‘What would you like us to do?’, and advertising and marketing saying, ‘Effectively, what are you able to do?’, and that results in an end result of what’s finest for promoting vehicles,” says Schifsky. “In any other case, you’re racing, which is gorgeous and kudos to everybody, however on the finish of the day we do it to promote vehicles.”
But when Acura doesn’t promote vehicles exterior of the US, does that imply we’ll by no means see the ARX-06 race at Le Mans?
“I disagree,” says Schifsky. “There’s some distinction of opinion. If and once we go, will we run it as a Honda or an Acura? The Acura workforce within the US will say it’s a worldwide race, and the impact of that race is not only felt in Europe. It’s a wide-reaching occasion.”

Salters provides: “In fact we’d all like to go, who wouldn’t? We’re right here to take care of the US so let’s do an affordable job of that first. It’s what pays the payments! We’ve bought to become familiar with these vehicles.
“We converse with our Honda Motor colleagues in Japan, they’re fairly – they love what we’re doing – however as a result of it’s international, it’s out of our remit. So, it’s what works for Honda Motor, it’s bought to be coherent, nevertheless it’s in dialogue. It’s a giant image factor, it’s as much as them to kind out.”
Schifsky clarifies: “Method 1, MotoGP and Le Mans are the three primary areas they’ve direct management over.”
And that leaves HPD to its personal units, with an Indy 500 crown and an IMSA title to defend, so it’s loads to be getting on with. For now, a minimum of…
