22.08.2017: FORMULA 1 PIRELLI BELGIAN GRAND PRIX Foreword from Renault Sport Racing Managing

FORMULA 1 PIRELLI BELGIAN GRAND PRIX



Foreword from Renault Sport Racing Managing Director, Cyril Abiteboul




The Belgian Grand Prix marks the beginning of the home stretch of the season and it’s vital that we hit the ground running by making a return to the points.



Hungary could have been a very strong weekend for us but the results failed to materialise. This was frustrating given we proved throughout the weekend in Budapest that we had the pace to be competitive and be in contention for a good haul of points from both drivers.



This highlighted the progress we have made in 2017. We have proved, on a number of occasions, that we have the ability to comfortably run inside the top ten and have shown we are well in the mix to be the best of the rest behind the top three teams.



 Weekends such as China, Bahrain, Spain and Great Britain showed what we are capable of doing, and there are nine more races to really underline our progression and make a mark.



These improvements have been down to the hard work being put in at Enstone and Viry, by our passionate workforce.



We are focusing on the areas needing attention, and making the necessary improvements and changes.



Clear steps are being made and we are heading in the right direction in terms of pace and reliability. The summer break came at a welcome time as we had the opportunity to reflect on these past few months and take a recharging period.



It would be impossible not to mention Robert Kubica’s test outing in the R.S.17 at the Hungaroring test, which was a very productive day from all involved. Robert’s journey back to an official Formula 1 test session is an incredible story and he delivered well on the day.



 He followed Test Driver Nicholas Latifi at the test, with both drivers contributing to our development of the car. Both Nico and Jolyon should benefit from the progress made at the test when they hit the track at Spa.



We are excited to get out to Belgium and restart the season on a bright note, but in order to do that we need to stay focused and work hard together as a team. Finishing the season in fifth is our objective, but it will take resilience and determination from everyone at Renault Sport Formula One Team.

 

 

Proving ground


Engine Technical Director Remi Taffin
explains how there is more to come from the R.E.17 and what can be expected from Spa; a circuit which demands high power output.



What can we expect from Spa?



We have the potential for a good result. Over the last few races our cars have been performing well and I can’t see any reason why Spa can’t continue that trend. Spa has high speed corners as well as a few straights which can be a real test.



We have to deal with the challenging section between La Source through to Les Combes. Drivers are full throttle for almost 2km and encounter the notorious Eau Rouge which will be fully loaded in this year’s cars with a lateral force of -3g.



Spa will be strenuous on the power unit given around 67% of the lap is spent at full throttle. But we have drivers driving well, a chassis that is performing well and an engine which is on track; it’s all pointing in the right direction.




How is performance looking?


We know we’re not the fastest on the grid, but as a team we are showing we are the force after the top three. Qualifying pace has looked good with Great Britain and Hungary exemplifying our ability to be the fourth best team. It’s just a case of building on that and bettering the race pace.


That comes from levelling up everything, we need to show off reliability and mileage and that is something we are giving close attention. We are on a good trend and we will keep adding performance in terms of both aerodynamics and engine so hopefully this can be seen in the upcoming races.




What have we got planned for the remainder of the season?


Spa and Monza will see new software and hardware updates. We are looking at Monza as a benchmark as it could provide a clear picture of the ranking of the engines. Being in the top ten will be a good result as these next two circuits are power-hungry. After Monza, we have more races and more things in the pipeline, the next two months will be important for the 2017 season outcome.




Track Notes:



Spa-Francorchamps is one of Formula 1’s historic races. Located deep in the trees, the circuit features fast bends, sharp elevation changes and boasts total unpredictability. Eau Rouge is amongst the most notorious of corners across any circuit in the world. With its 18% gradient, drivers hold tight and pray for grip through the left, right and left downhill then uphill combination which challenges car and driver alike.



T1 - The lap begins with the slowest corner on the 7.004km circuit – La Source, a tight right-hander.



T3 - The run down to Eau Rouge and into Raidillion creates extreme suspension compression as the relief changes from downhill to uphill. Good engine power is required for the uphill drag.



T7 - Using the gradient in the braking area to Les Combes, overtaking is easily possible here.



T10 - A series of more technical corners at Bruxelles and Rivage, where mechanical grip is important.



T12 - Pouhon is a fast flowing, double-apex left hand turn, which is exited flat out before the flow of Campus.



T15 - The two right hand corners at Stavelot and Paul Frere are crucial to optimize momentum up through the blind Blanchimont corner which is flat-out. Precision in placing the car is paramount here.



T19 - The final chicane, formerly known as the Bus Stop, is a tight right and left, which is an overtaking possibility on entry.




Power Unit Notes:




Spa is the hardest circuit of the year for the Power Units. Over 67% of the 7km track is spent flat out, which translates as around 73secs per lap, the longest accumulative wide open throttle time of the year.




The first period of sustained throttle is the climb from the La Source hairpin to the chicane at Les Combes. It takes around 25secs (1,852m) with the driver flat on the throttle throughout. The distance is only slighter shorter than a runway at Charles de Gaulle airport.



The track drops over 40m from La Source before climbing over 80m back to Les Combes, equivalent to a gradient of 1 in 4, or one of the steepest mountain climbs in the Tour de France.



The descent compresses the internals but going over the crest of the hill, the vertical force is suddenly lifted and the parts unloaded, with the vertical forces switching to -3g. It can be equated to the feeling on a rollercoaster drop when your body feels compressed and pushed down into the seat but weightless when you go over a bump.
 


The turbo will be rotating at close to its maximum to keep pace with the high rotational speeds of the ICE. The altitude will further increase rpm. At its most extreme the turbo will be spinning at more than 95,000rpm or over 1,500 revs per second!



Spa is one of the most demanding tracks on the MGU-K. Each of the braking points comes after a long burst of power so the energy dissipated through the brakes is enormous. The best opportunity for the MGU-K to recover energy is the Bus Stop chicane, which the driver approaches at well over 300kph and brakes down to just 75kph.



High-speed flowing corners such as Pouhon and Fagnes are the best opportunities for the MGU-H to recover energy. It will feed this energy to the MGU-K and ICE on the next period of throttle through Blanchimont. 
 



Tyres:



Soft (yellow) – Pale Lager - light in colour but heavy and bitter in taste.

Supersoft (red) – Flemish Red – a sour ale brewed in West Flanders; distinct in colour and has a real character.

Ultrasoft (purple) – Lambic – brewed in the Pajottenland region, dry and sour with potential for a sharp aftertaste.






In Numbers:


1,100 – There are over 1,100 varieties of beer in Belgium.


220,000 – Tons of chocolate produced in Belgium per year.


68 – (km) The longest tram-line in the world is the Belgian Coast Tram, running between the coastline on the French and Dutch borders.


400 – Brussels sprouts have been grown in Belgium for 400 years
