Rare air: How Red Bull’s ‘Showrun’ program takes F1 to extremes

A quick look at the history books will show Red Bull Racing’s RB7 as one of the greatest cars to ever race. With 18 poles from 19 starts, 12 victories, 10 fastest laps, and a drivers’ and constructors’ title double, it’s very much an icon.

Yet despite that stellar track record, it’s probably going to be more fondly remembered for things like doing donuts atop of the Burj Al Arab in Dubai, bombing down a ski slope in Austria, or traversing the Australian Outback.

Since 2012, a pair of RB7s — along with an RB8 which joined them in 2018 — have taken on a second life as the stars of Oracle Red Bull Racing’s “Showrun” program. It’s a unique promotional approach to Formula 1 that’s been seen by countless people across the world, but between its recent stops in Chicago and Nashville, the team gave RACER a rare insight into the inner workings of the operation.

The RB7 replaced the RB1 as Red Bull’s toy of choice, which ended its Showrun life sporting a bodykit to help it resemble a 2009-10 car. While from the outside, the RB7 of today still looks identical to how it raced in 2011 — save for an updated livery and some minor alterations to the sidepods to aid cooling — if you peel away the skin, you’ll find more substantial tweaks to the machine that took Sebastian Vettel to his second world title.

“We’ve got the RB7s that we use for show events and the filming side of things, and with those cars we sanitized them a lot in taking lots of bits and pieces off them, more to make them more reliable or to make them easier to maintain,” Red Bull’s heritage chief mechanic Greg Borrill tells RACER. “If it was just a race car, for example, we’d be bashing bits and pieces off them left, right and center, but we’ve taken some stuff off to make them a lot easier and more reliable to run.

“That loses a lot of the downforce that the car was originally designed with, so for track running we’ll use an RB8. The RB8 is pretty much taken straight from the racetrack in the fact that the diffusers all still intact; brake ducts, inlets, front wing, rear wing… it’s all very much a race car, so whenever you’re on track the driver’s got a lot more confidence in the car and knows what it’s going to do.”

That “sanitation” means that the RB7’s defining feature has had to take a hike. Sort of. Vettel recently got back behind the wheel of one for a run at the Nurburgring, where he was quick to note that the car’s famed blown diffuser that helped him and Red Bull carve out a dominant streak in the early 2010s was not present on the car.

“Well, technically it did still have the blown diffuser,” Borrill points out. “All the exhaust system and the floor, more or less, was still there, but what it didn’t have was the engine maps that you’d need to run to enable the blown diffuser to work properly, because then you’re looking at gasses still coming through when you’re off throttle and all that sort of business.

“They’re a lot more harsh when you’re running those sorts of maps and require a lot more upkeep on the engine side of things, but also from a car point of view.”

Speaking of harsh, Red Bull’s high jinks in the hands of regular demo drivers Patrick Friesacher and David Coulthard put the RB7 through a torrent of abuse, but when the race drivers get involved, that’s turned up another notch.

“That is generally when they catch fire, they don’t tend to give much of a hoot about it,” Borrill says with a smile. “The difficult thing with the cars is, with what we’re doing, we’re generally in confined spaces, we don’t have much speed, we’ve got a lot of high RPM because we’re doing donuts, we’re doing burnouts, we’re doing crowd-pleasing stuff, which is kind of what we’re here for. But because we don’t have the speed out of the car, we don’t have the airflow over the car, [so] we don’t have the cooling.

“On the 7s and 8, we have fitted radiator fans to try and help with the fact we’re doing this sort of stuff. They’re fully integrated onto the radiators and they’re controlled on the steering wheel with a rotary switch by the driver, so he can switch them on and off as he requires.”

“Obviously a standard F1 car doesn’t have fans fitted to the radiators or anything like that, but being an F1 car, we still have limits of what we can drive to.

“Water temperature is our biggest tell, so the dashboard of the car has the water temp readout, and we’ve got maximum of what it can be before the driver has to cool down the engine — so no donuts, no burnouts, just a couple of cool laps up and down to get the temperature back under control and into a level where or into a range where we’re happy for him to go again.”

The biggest victim of the RB7’s diet, though, is the KERS. Eliminating the electrification element not only helps ease-of-use, but is a safety precaution as well — and it goes some way to explaining why Red Bull has persevered with decade-plus-old machinery for its fun and games.

“You quite simply take the KERS system off the car,” Borrill explains. “You couldn’t do it nowadays with the current cars — the ERS and everything like that is fully integrated into the whole car — but with 7 and 8 it was simply a matter of being able to remove it. We’re operating with a lot less people in environments that are far more harsh than a race circuit, certainly less controlled than a race circuit.

“If we have any issues and the KERS system is fitted, we’re looking at possibly putting public or marshals who know less about the systems in a bit more danger. So we remove it for that aspect. But it just makes the car a lot simpler to run, as well.”

While the modern breed of F1 cars might be wildly complex, RACER can reveal that one of the latest generation will be joining the RB7s and RB8 in Red Bull’s Show Run fleet imminently — a 2022 RB18 — although it’ll be going through an even more dramatic transformation than the venerable present trio.

“We will be looking at a different power unit for that rather than what it was raced with,” Borrill says. “It’s very complicated — you can’t simply take the ERS system off — and also the cars themselves are a lot more complicated than the 7 and 8. It’s one of the reasons why we’ve used the 7 and 8 for so long, because they’re so easy to use.

“So we are looking at replacing that power unit with something else. It’s yet to be decided even what it’s going to be, but it’s still essentially going to be an RB18 for the rest of the car. So it’ll look like an RB18; it might sound something like an RB18.”

In the meantime, the deafening V8s will remain, with the help of Renault which, despite what the stickers on the engine cover tell you, is still very much involved with Red Bull’s running of older machinery.

“It’s really good — they’ve got a great team that we work with and have been working with since we started the program,” Borrill says of the team’s ongoing relationship with its previous engine supplier behind the scenes. “We obviously still rely on the original manufacturer’s input, and they still come away with us on each event to support us and they will continue to do so while the program continues. We still rely on their expertise to help us do what we need to do.”

While Red Bull itself gets to enjoy endless amounts of fun with its projects, the engine manufacturer’s input in the background isn’t all work and no play. Typically, before it turns a wheel at a public event, the RB7 breaks into song with a 2.4 liter rendition of “We Are The Champions,” “Seven Nation Army,? or one of a number of national anthems.

With all the talk of simplifying the cars, turning them into future Rock and Roll Hall of Fame nominees might sound like the most difficult part of the operation, but it’s a relatively simple procedure helped, in part, by Microsoft Office.

“It’s actually quite simple,” Borrill reveals, adding that they recently explored adding more tunes to the RB7 songbook. “It’s basically an Excel sheet that we have on the control side of things, and within that Excel sheet you match the hertz note of each song note, and correspondingly you can match that same hertz reading to the RPM of the engine and then you marry it altogether to make the whole track. That’s put into code, uploaded onto the ECU, then essentially you press ‘play’ when the car’s fired up and it does its thing.”

When it comes to staffing, Red Bull sticks to the reduce and simplify theme of the cars themselves, typically taking around 10 people — roughly 10 percent of the staff the team has at a grand prix — to each demonstration or filming outing.

“We operate in pretty different environments to the race team, we’re not just set up at a racetrack,” Borrill says. “But generally, the sort of generic procedures are still the same in terms of operating the car.

“It’s the same sequence in terms of fire-up and bits and pieces like that. We use the same basic structure of car crews in that we have a No. 1 mechanic that oversees the car, making sure that we’re built to the same spec and that we hit any sort of deadlines that we’ve got and they cascade information down to No. 2s and then we’ve got a power unit engineer, a controls engineer, the truckie… so, in that sense we operate in the same way that the race team does to operate an F1 car.”
