Huge regulatory changes make cars look mean

NEWS STORY
08/01/2017

No sooner had the new regulations for 2017 been announced than opinion was divided.

While some say the changes will shake up the order, others insist that in reality little will change.

While McLaren technical boss Tim Goss beleives that the former will prove correct and that the order will be shaken up, he says the 2017 contenders will look the part.

"We're looking at some huge regulatory changes ahead of the 2017 season," he admits to the McLaren website. "We've had bigger changes in the past, the change between 1982 and '83 from ground-effect to flat floors, for example, which had a massive impact on performance. But this season's changes rank as some of the most significant we've ever had in the sport.

"That's likely to change the competition order," he continues, "because it's such a big disturbance. Historically, that has changed the order, but then what normally happens is that the best, and most well-equipped, teams tend to rise to the top again.

"These new cars will definitely look different, and that was always one of the objectives of the rule-changes. The aim was to make the cars look more aggressive; to make them faster, so that F1 was very much at the pinnacle of motorsport in terms of outright speed, and to make them more difficult to drive. By that, we don't mean that they're more of a handful for the drivers, but that they're more physically demanding for them, so that they get out of the car having had to work hard like they did in years past.

"These 2017 cars are lower and squatter; they just look meaner," he insists. "The lower rear-wing, big fat tyres and big diffuser look cool – they look mean. But for the engineering department, the changes to the aerodynamic and tyre regulations are the two most challenging areas to tackle.

"The 2017 tyres are slightly larger in diameter, but, more significantly, they are wider. Imagine the old 2016 rear tyre now going on the front of the car, and a similar-sized increase on the rear tyre to accommodate.

"Pirelli ran a very intensive test programme during 2016 to develop the new tyres, with the support of three teams. They got lots of mileage under their belts throughout 2016, and all that data has been provided to all the other teams. But, from all of that testing, trying to piece together what we think the tyres are going to do in terms of performance, degradation, thermal stability etc, that's still quite challenging.

"And there's a couple of reasons for that: even nowadays, it's still quite difficult to understand tyre behaviour – even if you go track-testing. Additionally, the 2016 mule cars won't behave in the same way as the 2017 cars – so what we're trying to do is identify which areas of performance are attached to the tyre and which to the mule car. That's a major challenge.

"We're pretty close to knowing what we're going to get from the tyres, but really understanding how they'll sync with the new regulations will be quite a challenge. In pre-season testing, we will learn a lot.

"The aerodynamic changes have been another challenge," he admits. "A lot of the flow structures and physics on the car are fundamentally the same, how the flow is established at the front of the car and then travels back down the car, starts off in a fairly similar way to last year.

"Now what you'll find is that, in the detail, things start to behave differently, which prompts you to change direction. The 2017 cars will look pretty similar to the layman, but the aero guys have been battling to correct flow-structures at different ride heights for months and months now. We've had to rethink lots of different areas on the car, because they're behaving differently to how they did before.

"The track width has gone out by 100mm per side so the cars are wider. And because of that increased width, the front wing has also grown wider. And it's now swept back in plan-view.

"The rear wing is also wider and lower which helps make the whole car look lower and wider. And there are some visual styling cues that have been introduced: the rear is swept back in side-view, and the sidepod intakes are angled in plan-view. It's definitely a 'meaner' look.

"And there's a detail in the rear-wing endplate regulations; they step in and that curviness is another styling feature that adds to the general 'aura' around the new shape.

"The new regulations allow us to run a much larger bargeboard. There's much more freedom in that area – so you'll probably see that every team has done a lot of detailed work in that area. In the 2016 regulations, the scope for bargeboard development was quite small. Now we can run them to the full height of the chassis, they can go a lot further forward and sit wider outboard. We can also stack devices within that area – so you'll see a lot more complication in that area, a little like we saw in previous regulatory eras.

"The bodywork and floor have both got wider," he continues. "The leading edge of the bib area has been brought rearwards by 100mm, that's not hugely significant, it's a weight-saving concept, but, with the increase in the width of the car, there's more floor area, which means more aerodynamic load.

"The most significant change in this area is the rear diffuser. It's longer and higher and that will create a lower pressure in the centre of the floor and create more downforce. The 2017 diffuser now starts earlier and goes to a higher height. It previously started at the rear-axle centre-line, it's now 170mm further forward, around halfway towards the leading edge of the tyre. Last year, the height was 125mm above the reference plane, and it's now 175mm.

"The drivers say that these new cars will be more challenging to drive, and that they'll have to work harder and concentrate more to get the best from them.

"One knock-on from that is that we'll no longer classify some corners as 'corners'," he reveals. "What we mean by that is that engineers define a corner as a point on the track where the driver has to lift and essentially drive and handle the car through it; if he's going round a bend, and his foot is flat to the floor on the accelerator, we class that as a straight. As the new cars will be going faster, some of 2016's 'corners' will be classified as 'straights'. But because they'll be going through them faster, they'll be subjected to more g-forces and that's still tiring on the body."

"New aspects to cars, same expensive awful sounding, unnecessarily complex, little benefiting the road car world, they have hybrid figured out already, waiting for better battery tech, which is NOT in F1 cars yet, F1 batteries too expensive-cooling too expensive.

So where does that get F1, awful sounding, overly complex, not enuf competition, or will there be some for a change - F1 too much like nascar - too limited too formulaic, too boring & expensive.

"

"@scf1fan - could not agree more!

"faster cars" does not mean automatically the overtaking/excitement is going to be easier. 10 years ago cars were faster, but I also felt asleep faster during the races (remember the Jarno Trulli trains?) ...

I want to see the drivers fight for their position. I want to them to be mistake-prone. I want them to _work_! I want them to be my heroes (they're our age gladiators) and to be worthy. I know Newey is a genius and I truly believe he is the one who had the biggest impact in F1. But, as a kid, I only had posters with Senna/Mansell/Hakkinen and likes in my room. No active-suspension, no flexi-wing, no hydraulic-chassis or whatever other widget Newey/* invented. Drivers are making F1 entertaining. Engineer's job is to make it dull, predictable (yes, extreme pov, but it's also the truth).

I went few months ago to a go-kart track to see a teen-race. It was true the leader never changed, but there were 2-3 drivers who were literally breathing on his neck the entire race and never let the audience sit. The guy who was able to sustain the pressure, keep his head cool and win the race really worth it. That was exciting. And we all know how 'mean' a go-kart looks like."

"Looks "mean?" Or looks like a Cuisinart? This reminds me of when Andrew Agassi was doing the Canon commercials; "Image is everything." That was a clever play on words for a camera company, but it did nothing for AA. Instead of trying to regulate the looks of the cars so that they "look" more exciting, why not just come up with rules that make sense for racing, and then let the teams design the cars so that they're more competitive and ARE more exciting!"
