Four array – 4 array stops: Pace and soundness in all aspects.

Posted on 10. Aug, 2018 by in BMW Canada

Munich. Perfect array stops are critical for success in every
competition series. While it will be essentially about a speed of changing
tyres during subsequent weekend’s DTM races in Brands Hatch (GBR), in
continuation races such as a 24 Hours of Spa-Francorchamps (BEL),
it’s a right timing and coordination of a opposite procedures
that is crucial. In further to changing a tyres, a automobile is
refuelled and a new motorist enters a cockpit. We yield an
overview of a array stops in a several competition array in that BMW M
Motorsport is concerned and review a stops during a arriving DTM
races with those in a FIA WEC, a IMSA array and during the
Spa-Francorchamps 24 Hours.

 

DTM:

 

Key Facts:

 

Team/car:                   

BMW Team RBM / BMW M4 DTM

Duration:                   

Approx. 7 seconds stationary, no refuelling allowed

Persons:                                

9 group members directly on a car, and one chairman during a array wall
manning array board, one chairman on a group radio and a personality of a stop

Procedure:                            

Decide to stop, use a array house to uncover a motorist and endorse via
radio, radio vigilance to a array crew, indoctrinate a motorist on a change
position, after braking, lift a automobile regulating a pneumatic jack and
disencumber front tyres, change a front tyres, mechanics run to a rear,
change a behind tyres, all-clear handsign of gunmen, recover a car,
expostulate off and check a trade in a array line around radio and/or the
lollipop man

Speed limit:              

60 km/h (Norisring, Zandvoort, and Brands Hatch 50 km/h)

 

The Challenge:

The array stops in a DTM are a good mental and earthy aria for
a whole team, as they can confirm a competition in a offset starting
margin so good credentials and consistent array stop use is standard
procession for all group members. For a drivers, it is critical to
get a cold tyres (regulations no longer concede preheating) adult to the
scold heat as quick as probable after returning to a track.

 

Driver Perspective – Philipp Eng (AUT):        

“The array stop is of good stress in a DTM. The spin of
opening in a DTM is unequivocally high, that is given a array organisation is
important. You always win and remove together. It is critical that you
stop as late as probable before a array stop line and don’t rubbish any
time. You can’t expostulate too quick when branch off a ‘fast lane’ to
your mark given we need to stop accurately during a lollipop. When the
automobile is in a atmosphere and a guys are changing a tyres, we can tell
either it is a quick or delayed stop. When they run to a behind axle, I
demeanour in a rear-view counterpart to make certain that no other automobile is
entering a ‘fast lane’. Then, when a automobile is lowered, that’s my cue
to put my feet on a accelerator.”

 

 

FIA World Endurance Championship:

 

Key Facts:

 

Team/car:                  

BMW Team MTEK / BMW M8 GTE

Duration:                   

Approx. 35 seconds still (depending on a volume refuelled)

Persons:                                

8 group members during a automobile (4 mechanics, 1 lollipop man, 2 refuellers,
1 glow extinguisher)

Procedure:                           

Refuel, tyre change and check during a same time, together driver
change, where applicable

Speed limit:              

60 km/h

 

The Challenge:

The coherence of a array stops via a whole continuation race
and a ideal communication between driver, array organisation and engineers,
utterly in a box of random stops, are crucial. Then on top
of that is a plea of changing brakes in a 24-hour race.

 

Driver Perspective – António Félix da Costa (POR):

“Pit stops in a FIA WEC are a genuine plea given we need
to change a drivers some-more quick than a 35 seconds that it takes
to refuel. Getting out, removing in, and in particular, a new driver
buckling adult scrupulously and firmly in 25 seconds is distant from easy.
Training for these procedures is one of a many critical tasks ahead
of a race.”

 

 

IMSA WeatherTech SportsCar Championship:

 

Key Facts:

 

Team/car:                  

BMW Team RLL / BMW M8 GTE

Duration:                               

34 seconds, as per regulations, for full refuelling, not singular when
fuel apportion is lower, tyre change 16 seconds, motorist change 20 seconds

Persons:                                

4 group members during a automobile (3 tyre changers, 1 refueller), and the
second driver, who helps with removing in and buckling up

Procedure:                            

Refuel, change tyres and check during a same time, together driver
change, where applicable, start a automobile after tyre change, during refuelling

Speed limit:              

60 km/h (37 mph)

 

The Challenge:

In contrariety with all a European competition series, there is a array wall in
a USA, that everybody concerned in a array stop has to burst over
before springing into action. The categorical cause is a coherence and
reserve of array stops in line with before planning. Which is given a team
practices array stops and procedures in any session, and all team
members work on their earthy fitness.

 

Driver Perspective – Connor De Phillippi (USA):

“It seems like all all around we is using in slow
suit given it is so quiet. The engine is off and everybody out
there is doing their job. The automobile goes adult super fast, we unequivocally feel
it in your reduce back. The operative gives a motorist and array organisation the
information on how most fuel has already been put in and depends down
a time. Then, during a end, a automechanic during a front right of a car
removes a atmosphere hose and a automobile drops unequivocally quickly. It’s roughly like
being on a drum coaster. Then a adrenaline kicks behind in.”

 

 

24 Hours of Spa-Francorchamps (Blancpain GT Series):

 

Key Facts:

 

Team/car:                   

ROWE Racing / BMW M6 GT3

Duration:                   

Approx. 35 seconds still (depending on a volume refuelled).
The organiser defines a smallest generation for a whole array stop,
including entrance and exist for any line (in Spa it is 1:50 minutes)

Persons:                    

8 group members in a array line (1 lollipop man,1 windscreen washer, 2
tyre changers, 3 people for refuelling, holding a hose and fire
extinguishing, where applicable, 1 stop controller), another 4
mechanics for holding a tyres into a pitlane

Procedure:                

Refuel, change tyres and check all during a same time, motorist change in
parallel, where applicable

Speed limit:              

50 km/h

 

The Challenge:      

Sticking to a predefined smallest array stop times as closely as
probable so that we don’t remove any time, and timing a array stops in
a competition to soundness strategically and tactically, for example
during yellow dwindle or reserve automobile periods. This relates to the
predefined technical stop between a 10th and
15th hour of racing, that contingency take a sum of five
minutes, including entrance and exit, and ideally is used to change the
stop discs. Also, in any entertain of a competition (once within six
hours), a group has a buffoon array stop, for that no smallest duration
applies. Ideally, we can benefit 10 to 15 seconds in these stops.

 

Driver Perspective – Jens Klingmann (GER):

“The hurdles of a array stops during Spa start with a tangible pit
lane. It is by distant a longest array line on a racing calendar.
Basically, it is dual lanes that are related by a slight turn. This
means it takes a prolonged time to expostulate by a array lane, which
enables a motorist to check all in advance. When changing
drivers, we have utterly a bit of time given a refuelling usually takes
30 seconds in a pit. Primarily, it is critical that a drivers sit
perfectly. There is a arrangement in a automobile to hang to a smallest time
from entering a array line to exiting as closely as possible.”
