Chinese F1 Grand Prix 2012: Preview + Feature (MBAMGF1)

Round three of the 2012 Formula One World Championship, the UBS Chinese Grand Prix, takes place at the Shanghai International Circuit on Sunday 15 April. The 5.451 km Herman Tilke designed circuit made its debut on the calendar in 2004 and is shaped to represent the Chinese ‘shang’ character.

• Since 2004, the eight races have been won by seven different drivers; only Hamilton has won twice (in 2008 & 2011)
• The 1170 m back straight is among the season´s longest, with the cars at wide open throttle for 15.5 seconds
• At peak revs on that straight, the engine´s pistons will be accelerating at 81,000 m/s2 , equivalent to over 8,250 G


Michael Schumacher
“When I think about the Chinese Grand Prix, the fans are the first thing that comes to mind. For many years now, I’ve had a big and loyal fan base there, and it’s still very touching to see the lengths they go to in supporting me. A big thank you to all of them! As for the race itself, I’ve never had much luck in Shanghai, apart from my win in 2006; however that could change this year. In the first two races of 2012, we didn’t manage to maintain our qualifying pace in race conditions. We’ve been working intensively on this, so that we can offer our fans a strong performance in China.”

Nico Rosberg
“I have good memories of the Chinese Grand Prix as I was on the podium there in 2010 and led the race last year. I like the Shanghai International Circuit very much with its many unique, long corners. For me, China is really the start of the season as the first two races have not gone to plan. The track is quite different to the first two, as it demands more from the front tyres than the rears - in other words, what is termed a front-limited circuit. We know that we have a quick car, but we are looking to improve our long run pace in China next weekend and to have a better race performance.”

Ross Brawn, Team Principal
“The Chinese Grand Prix takes place at the very impressive Shanghai International Circuit and has really established itself on the Formula One calendar in recent years. China is an important and growing market for our sport, and indeed for Mercedes-Benz, and we look forward to our annual visit next week. On track, we hope that the weekend will prove more successful than the first two races of the season where our race results did not match expectations after a positive start to both weekends. A lot of hard work and analysis has taken place back at the factory since our return, and I hope to see these efforts pay dividends next Sunday in Shanghai with a performance which reflects the capabilities of the F1 W03.”

Norbert Haug, Vice-President, Mercedes-Benz Motorsport

“The first two races of the 2012 Formula One season have been ones of unfulfilled promise for our team. Michael’s second row qualifying positions were less than half a second from pole in Australia and Malaysia, however at both events we did not convert our qualifying speed into a consistent race performance on Sunday when it counts. Since the last race in Malaysia, the team has conducted analysis of our tyre usage during the first two rounds, and how we can improve. The Chinese Grand Prix will provide an answer on our progress, although weather conditions and circuit characteristics will be different to either Melbourne or Malaysia. The 1170 metre back straight accounts for over 20% of the lap distance, the cars exceed 285 kph on four different occasions, and nine of the circuit’s corners are considered to be low or medium speed, with five taken at less than 100 kph. Our team has been hard at work since Malaysia, and we hope to be able to translate our learning process into consistent and competitive lap times on race day in China.”

Race Preview Feature: Cracking the Conundrum
Two races into the 2012 season, and firm conclusions are very hard to come by when assessing the true competitiveness of the teams. The results from the first two races indicate that this could be one of the most open seasons for years, with seven different teams finishing in the top ten in Melbourne - and nine in the mixed conditions of Sepang. Even in qualifying, the margins are incredibly close: the top ten qualifiers from Q2 at the first two races were separated by an average of eight-tenths of a second, compared to 1.5 seconds in the first two races of last year. In such a tightly matched field, small details make a huge difference.

For MERCEDES AMG PETRONAS, the time between the races in Malaysia and China has been spent trying to unravel a conundrum: why hasn’t strong qualifying speed been translated into a similar level of competitiveness on Sundays?

“In both races, our problems have been related to getting the tyres into the correct working window,” explains Team Principal Ross Brawn. “However, at each race it was at different ends of the scale: in Melbourne, we overheated the tyres - it was under control on Friday, then we developed the set-up in a direction which did not prove helpful in the warmer conditions. In Malaysia, having done a lot of work in practice to make sure we didn’t suffer from the same problem, the cooler conditions on Sunday dropped us out of the window again.”

Temperature readings give a clearer picture of the shift: while on Friday and Saturday, track temperatures were in the mid-40s in Sepang (peaking at 45°C on Friday), they hovered around 30°C in the race. “In the dry at the end of the race, we got the car working more effectively and our pace was more respectable. But I still don’t feel we really got the tyres working well, gripping hard and operating at optimum temperature.”

The consequence of the drop in temperatures was to flip the primary challenge of the race on its head: instead of needing to protect the tyres from overheating, it was critical to generate tyre temperature in the cooler conditions. More than one team experienced a loss of relative competitiveness compared to Saturday. “The result in Malaysia was a great one for Formula One - but certainly not what would have been predicted before the start,” continues Brawn. “Like other teams at the front of the grid, we spent two days getting tyre temperatures down - and then, in the race, found that we needed to work the tyre harder. The cooler conditions reversed what was needed from the cars.”

However, circumstance alone does not explain the team’s difficulties at the opening races of the season. “We have too narrow a window in which we are operating the car - and we have to broaden that, and build more tolerance into how we are using the tyres,” explains Brawn. “When we encounter challenges like this, we look at all areas of the car and we challenge ourselves collectively to find the solutions we need. But our qualifying speed tells us that the fundamentals of performance are there: you can’t do the lap times if you don’t have enough downforce, horsepower or a good chassis.”

So far, the potential of the F1 W03 has only been glimpsed on Saturday. At both races, the best of the team’s cars has qualified less than half a second from pole position - in 2011, the closest the team got to pole was 0.525s in Turkey. The step forward in basic performance is clear to see and there is no reason to believe that it cannot be translated to race conditions.

“Our objective is to build the best car we can for the race - and our qualifying performances are a consequence of that,” continues Brawn. “Nothing has been consciously done to focus on making the car quick in qualifying, and not so good in the race, because under the current rules - with DRS and the number of pit stops - there are no real rewards for doing so. Using the tyres properly is vital for success, and it depends on a number of factors, including set-up, the downforce the car is generating and the drivers’ approach. Within the set-up variations we can choose, we have the opportunity to find the right solution. But it’s a learning process, and we missed the mark at the first two races.”

What then of prospects for Shanghai? Practice data from Sepang indicated that, in dry conditions, race performance should have been more consistent than in Melbourne. China will provide an opportunity to confirm this. “Our analysis since Malaysia has given us an even better understanding, and we have plans and actions in place to improve our tyre management,” concludes Brawn. “We clearly have a reasonably quick car - we have shown that in qualifying - and now we have to convert our speed into race performance.”

Malaysian F1 Grand Prix 2012: Race Preview Feature - The Safety Car… and a special anniversary

The Malaysian Grand Prix holds the unique distinction of being the only Grand Prix circuit at which the Safety Car has not been officially deployed in the past ten years - in spite of often unpredictable weather conditions. With Mercedes-AMG once again supplying both the Official F1™ Safety Car and Official F1™ Medical Car for 2012 - the 17th season in which it has done so - it’s the perfect opportunity to look at how often this race-changing factor comes into play…


How much was the Safety Car used in 2011?
Last season saw the Safety Car deployed for 4.9% of the season - a total of 12 deployments, over seven races, for 61 laps or 284.3 kilometres. This compares to 21 deployments in 12 races in 2010, for a total of 7.8% of the season over 452.3 kilometres. This reduction was in spite of a significant increase in on-track overtaking through the combination of the Pirelli tyres and DRS rear wing system. However, while there was an overall reduction in Safety Car deployments, the 2011 Canadian Grand Prix featured five Safety Car phases over 32 laps, or 139.6 kilometres: this represented 45.7% of the race distance, a record in Formula One.

Which races feature the highest and lowest probabilities of Safety Car deployment?
The races with the highest historical probability of Safety Car deployment are in Singapore and Korea: every race held at these venues has seen at least one deployment (four races in Singapore, two in Korea). Canada (14 deployments in last nine races) and Monaco (13 deployments in last ten races) also feature prominently. As for the lowest likelihood, aside from the Indian circuit which has only hosted a single race, this is in Malaysia (no official deployments in the past ten years), Bahrain (one deployment in seven races) and Hungary (two deployments in last ten races).

Wasn’t the Safety Car deployed during the 2009 Malaysian Grand Prix?
The Safety Car was indeed deployed on lap 32 of the race, before the event was red flagged on lap 33. However, the official race results only run to lap 31, so the Safety Car deployment is not considered for statistical purposes.

Which cars are used for the Official F1™ Safety Car and Official F1™ Medical Car?
The Official F1™ Safety Car is the SLS AMG, with a 6.3-litre V8 engine developing a peak output of 420 kW (571 hp) at 6800 rpm and maximum torque of 650 Nm at 4750 rpm. The engine, power train, suspension and braking system of the Safety Car are the same as those found in the standard production SLS AMG. The Official F1™ Medical Car is the C 63 AMG Estate, which produces 358 kW (487 hp) - an extra 30 hp compared to the standard model thanks to forged pistons, connecting rods and lightweight crankshaft from the SLS AMG. These components are three kilograms lighter than standard. The first Mercedes-AMG Safety and Medical Cars were the C 36 AMG, which was first used in 1996, although an AMG E-Class Coupe was occasionally used as the Medical Car as early as 1984.

111 years of sporting success

March 25 1901 was a Monday - a strange day for a motor race, to modern eyes. But in spite of inclement weather in the South of France, the second day of the 1901 Nice Speed Weeks saw the race for “speed cars” held over a route from Nice to Salon, and back; a total of 392.5 km on open roads. This was the first major outing of the year for the new Daimler competition vehicles, newly christened ‘Mercedes’ after one of the daughters of importer Emil Jellinek.

The new cars had attempted to race in Pau the previous month, but had failed shortly after the start. However, the Nice-Salon-Nice race proved more successful: driver Wilhelm Werner (mechanic to the Baron Henri de Rothschild) led by 12 minutes at the halfway point, and eventually won - after a bruising 6 hours, 45 minutes and 48 seconds of racing - by the healthy margin of 26 minutes and 10 seconds (by way of comparison, this would represent a lead of nearly 6 minutes in a 1.5 hour modern Grand Prix!), at an average of 58.1 kph.

Sunday marks the 111th anniversary of the first competition success for a Mercedes vehicle; in the intervening years, Mercedes - which became Mercedes-Benz in 1926 - has set new benchmarks in every series in which it has raced. Last Sunday’s Australian Grand Prix marked the 89th Formula One victory for Mercedes-Benz power, and the 36th win for the current generation of V8 engine, continuing a heritage that is longer than any other in the sport.

Australian F1 Grand Prix 2012: Race Preview Feature - Regulation Changes for 2012

It wouldn’t be a new Formula One season without a few new regulations to get our heads around. For 2012, they are relatively few in number, but have had a dramatic impact on the look of the current generation of Formula One cars - and also have the potential to alter the sporting outcome of races. Here are the most important new sections of the 2012 Sporting and Technical Regulations.


Sporting Regulations

• Maximum race time: Art. 5.3, no race may now last longer than a maximum of four hours. Last year’s Canadian Grand Prix lasted a total of 4hrs 4min 39.537s, although only 57min 10s were actually spent at racing speed!

• Driving etiquette: Arts. 20.2 & 20.3, drivers may no longer leave the track without “justifiable reason”, while the acceptable limits of defensive driving have now been formally written into the rules. Drivers may not make “more than one change of direction to defend a position” and, when moving back onto the racing line, must leave racing room - “at least one car width” - between their car and the edge of the track.

• Crash testing: Art. 22.2, all mandatory crash tests must be completed prior to a team conducting any track testing. This was previously only mandatory for race events.

• In-season testing: Art. 22.4 (i), provision has now been made for one three-day in-season test, to be held in Mugello from 1 to 3 May. MERCEDES AMG PETRONAS topped the tables for average daily mileage in pre-season testing, completing an average of 472 km per official test day with the F1 W03. The car completed a total of 4,250 km over nine official test days, plus a further 200 km during filming days, with just two on-track stoppages.

• Team curfew exemptions: Art. 30.19, team catering, marketing and media personnel are now formally exempted from the curfew observed by other team members.

• New Safety Car rules: Art. 40.12, if it is considered safe to do so, cars that have been lapped by the leader will be allowed to unlap themselves under the Safety Car. This will have the effect of putting the field in position order at every restart and leaving all cars free to race, rather than the leaders having to pass backmarkers, thus improving the racing - in 2011 in Singapore, after the Safety Car period, the presence of backmarkers allowed Sebastian Vettel to build a nine-second lead over second-placed Jenson Button in a single lap! The Safety Car was deployed a total of 12 times over seven races in 2011, compared to 21 times over 12 races in 2010.


Technical Regulations

• Lower nose height: Art. 3.7.9, “No bodywork situated more than 1950mm forward of the rear face of the cockpit entry template may be more than 550mm above the reference plane.” This apparently anodyne sentence is at the root of the distinctive stepped-nose appearance of the majority of 2012 Formula One cars, as the maximum permitted chassis height remains at 625mm above the reference plane.

• Reduced tolerances: Art 3.12.6, permitted manufacturing tolerances for aerodynamic components have been reduced by some 40% to 3mm (from 5mm previously).


• Throttle and exhaust controls: Arts. 5.5, 5.6, 5.7, 5.8, the regulations covering these areas now amount to a total of 954 words (!) and regulate the use of engine throttles, engine torque demands and the positioning of exhaust outlets. This section of the rules is over ten times longer than it was 12 months ago: in 2011, the same regulations were totalled just 89 words, a reflection of the complexity of the ‘blown diffuser’ systems the new regulations aim to outlaw.

• Additional load test: Art. 18.9.2, an additional vertical load test on the lateral impact structures on the chassis brings to 18 the total number of load and impact tests a chassis must pass in order to receive FIA homologation.

Brazilian F1 Grand Prix 2011: Race Preview Feature - Season Overtaking Analysis (MGP)

Overtaking – how much, not enough, or too much of the ‘wrong’ sort – has been a frequent topic throughout the 2011 season, since the advent of DRS (the Drag Reduction System) and Pirelli tyres. What is beyond all doubt is that the overall levels of overtaking have climbed to record levels – there have been nearly 1500 passes so far in 18 races. However, no standard definition of an overtaking manoeuvre exists. The figures used below are calculated for strategic purposes, which are reflected in the categorisation, and compiled from a combination of video, timing data and GPS technology. Overtakes are classed as follows: Normal/DRS/Slow Cars (referring to HRT, Lotus and Virgin, as the strategic value of these overtakes is different)/Team-Mates (one driver can choose to let another pass)/Damage/Lap One.


How many overtaking manoeuvres have been made in 18 races this season?
So far, there have been 1436 overtaking manoeuvres in all categories. Excluding overtakes categorised as ‘Lap One’ or because of damage, there have been 1180 manoeuvres. The combined total of ‘Normal’ and ‘DRS-assisted’ moves – the indicator of what most observers consider to be ‘clean’ overtaking – is 804 overtakes. This gives an average of 45 normal and DRS overtakes per race.

What is the breakdown of overtaking manoeuvres within these totals?
There have been 441 normal overtakes this season and 363 DRS overtakes; from the total of 804 clean overtakes, 55% were normal and 45% were DRS. 300 overtakes were on the three slowest teams by faster cars, with passes between team-mates accounting for 76 overtakes.

Which races have seen the most overtakes and which the least?
The highest number of clean overtakes were recorded in Turkey (85), Canada (79) and China (67). The races with the fewest were Monaco (16), Australia (17) and India (18). Nine races featured fewer than 50 clean overtakes; eight races featured more than 50. There have been an average of 45 clean overtakes per race – broken down to 25 normal overtakes and 20 with DRS.

What has been the ratio of DRS to normal passes through the season?
The highest ratio of DRS overtakes to normal, ie where the influence of DRS was greatest, were: Abu Dhabi (89%), Europe (81%), India (78%), Turkey (59%) and Spain (57%). The lowest ratio of DRS overtakes to normal were: Monaco (13%), Hungary (20%), Canada (22%), Japan (26%) and Great Britain (27%) – it should be noted that three of these five races featured wet or mixed conditions, and use of DRS was restricted for portions of the race in Canada and Great Britain. DRS overtakes have outnumbered normal moves in eight of 18 races.

Has the ratio of DRS passes changed during the season?
In the first nine races of the season, there were on average 21 DRS overtakes per race – on average, 45% of clean overtakes. The influence of DRS has remained stable in the second nine races of the year: there were on average 20 DRS overtakes per race, representing on average 46% of clean overtakes.

Which driver has been the top overtaker in 2011?
The following figures are corrected for retirements of cars ahead, but only positions gained are considered. Buemi has made a total of 112 overtakes in 2011 – closely followed by Michael (111), Kobayashi (95), Alguersuari (90) and Perez (89). This total can be broken down into gains between the start and the end of sector one (top starter), gains on the first lap and gains in the race not including lap one.

Who has been the top starter in 2011?
The top starter is Michael, who has gained a total of 34 positions; next up come Buemi (29), Kovalainen (28), Liuzzi (20) and Kobayashi (19). In contrast, the driver who has gained the fewest positions in sector one is Vettel, with just one place gained all season, reflecting the fact that he has only once failed to qualify on the front row in 18 races, including 14 pole positions.

Who has gained most positions on the first lap in 2011?
In total terms, Michael, Buemi and Kovalainen also lead this table, having gained 40, 30 and 26 positions respectively on lap one. Discounting gains made in sector one, the top-ranked driver is D’Ambrosio, who has gained 8 places between the end of sector one and lap one.

Finally, who has done the most overtaking in the races after lap one?
This classification is headed by Perez and Buemi, both with 82 overtakes. They are followed by Button (77), Webber (76), Alguersuari (74) and Michael (71).
