97 & Holding

Posted by Mark in Uncategorized, Technology

Peter Windsor congratulated & Felipe Massa acknowledged Bridgestone for their 100th pole position in Formula 1 at the Bahrain Grand Prix during the post-qualifying driver interviews.  Is it really a milestone when you are competing against yourself?  At the end of this season, Bridgestone will have a total of 114 pole positions and claimed every pole in 2007.  Some might say, “Impressive,” not really when Michelin leaves the series a year early & you are the exclusive tire supplier to every team competing.  I also don’t think any of the poles won while there is a single tire supplier should be included in their numbers & stats….so by my calculations lets just call it 97 & holding….

Another interesting hypothetical related to tires that I will make no attempt to answer on my own: How close would the driver’s championship be with Michelin still in the game?  Would Renault be so far behind?  Would McLaren-Mercedes be so much improved?  Would BMW Sauber be even stronger on Michelins?  Where would Ferrari be in regards to the other heavy hitters?  By pulling out of competition a year before the single-tire contract went in to effect in 2008, did Michelin single-handedly rob F1 fans of an even more competitive championship fight?  How very French of them, “I surrender.”

What kind of tires are on your car???

NASCAR Racing on Its Heritage

Posted by Steve in Technology, NASCAR

It is not news to anyone that NASCAR has its roots in running illegal spirits from distillery to distribution in the souped-up automobiles them good ol’ boys made to do the running. It was inevitable that Jethro pontificated to Cletus, “My car is faster than yers.” Wherein reply Cletus proffered, “No it ain’t.” To which a polemic ensued. In order to resolve such a dilemma, the fellers drew themselves a circle about which they would race, as they did not want to get lost. History.

Well in an bio-conscious bit of irony, a GM vice-president suggested that:

Joe Sixpack would be more likely to try ethanol if his NASCAR heroes were using the fuel,… NASCAR fans tend to be strong “America First” proponents, so they would support the racing circuit adopting fuel that is made in the USA.

Listen. You can hear the South chortle in their retort: “Ethanol in NASCAR!!!! Hooooooooweeeee! Them city folk sure talkin’ silly now! We can’t be divertin’ the corn crop from sour mash to runnin’ our cars. Although Grandpappy used to say his Silverlightin’ could do everything from keep the motor runnin’, to cleanin’ the chrome on his old Buick.”

Seriously, it took NASCAR how many years to get the lead out, and now they are expecting them to switch to ethanol? Next thing you know, they’ll start talking about being carbon neutral. (Isn’t that liking marrying your sister in West Virginia?)

Is Raikkonen Overrated?

Is Kimi Raikkonen overrated as a Formula One driver? Jacques Villenueve seems to think so. It has been reported by GPUpdate.net and the BBC that Jacques Villenueve questions Kimi Raikkonen’s ability to drive a team to be number one.

This is an interesting point. Jacques is not questioning whether Kimi can turn quick laps and win races. Rather, he is questioning Kimi’s dedication to the sport to be number one. Primarily, does Kimi has the acumen to take the team he is with and their car and develop it so that he can consistently win races with the best performing equipment possible.

This is the question to be answered in 2007. In the past, Kimi’s performance at McLaren was marred with equipment failures that seemingly robbed him of his first championship. Or is it that Kimi could not drive the car that McLaren gave him in a way that would make the car last? Did Kimi bring on his own mechanical failures by his driving style and his inability to communicate the issues he was experiencing to his engineering staff?

Juan Pablo Montoya did not have the same mechnical reliability issues during his tenure that Kimi experienced with McLaren. (JPM brought on his own mechnical failures by driving the car like a mad man!) If Kimi is just a “fast” driver and not much more than that, it will become extremely apparent with Ferrari, where in the past, Michael Schumacher’s technical acumen delivered a fast and reliable car for Ferrari year-after-year. Schumacher knew how to drive fast within the limits of the car and then work with the engineers to extend those limits taking him even faster.

At McLaren, it was clearly evident that Kimi could drive the car fast, but beyond the limits that the car could sustain for an entire race. It is that ability to communicate where those limits are and how the car behaves at those limits that the engineers need in order to continue to improve on the car’s setup to extend those limits. That is the certain “je ne sais quoi” that Villenueve ascribes to not only Michael Schumacher, but all great champions of the sport, and more importantly, decrys Kimi Raikkonen for lacking.

What the #$%! is a Centerline Drag Generating Wing?

Posted by Steve in Technology
Do you remember when you were a kid, and you received your two front teeth for Christmas? You had them, but they had a gap in between them. It took until the rest of your adult teeth arrived to push them together (or your parents paid thousands of dollars to an orthodontist to mechanically aid the process). Well, until that time, you could amaze yourself and your friends (though, not really your parents - or anyone older than age 12 for that matter) with the fact that you could squirt a perfect stream of water (or whatever beverage you may have been consuming) between those teeth. CDG Wing
Well, that smooth stream of water squirting between your teeth is representative of a Centerline Drag. Now place those two buck teeth, one each, over the rear tires of a F1 car and you have a Centerline Drag Generating Wing!
The FIA had proposed the introduction of a Centerline Drag Generating (CDG) wing for the 2007 season as a modification to the existing aerodynamic rules to increase passing in Formula One. Due to a response from the manufacturers, any proposed aerodynamic changes have been postponed until 2009.
Under the currrent aerodynamic guidelines, it is nearly impossible for one car to follow closely enough in the slipstream of another to promote passing (save for on long straight-a-ways where one can “draft” and then slingshot around due to the preceived horsepower advantage). However, this is not possible during corning or through more technical sections of a race track. Due to the copious amounts of downforce generated by the existing aero-packages and modern wing designs, the resulting turbulence robs the trailing car the effect of its aerodynamic package thereby reducing its aerodynamically induced grip (i.e., control).
By introducing the CDG wing, FIA hopes to promote more wheel-to-wheel racing and overtaking. Sounds like NASCRAP to me. We all have watched the starts to F1 races where there is clearly “wheel-to-wheel” racing and, invariably, cars are taken out due to those wheels touching one another. Wheel-to-wheel racing is not necessarily conducive to open-wheel racing.
If the FIA seriously wants to promote more wheel-to-wheel racing, they had better promulgate rules bolstering components such as suspensions in order to handle the greater amount of loads and stresses that they will experience due to more collisions. The current carbon fiber-based suspensions cannot withstand the addtional stresses of “wheel-to-wheel” racing.

Be Careful What You Wish For

Posted by Steve in Racing Places, Technology, NASCAR

The F1blog had an interesting post today: Five Wishes (he had ten, but then dropped one of the stone tablets and only has five left) to make F1 more “TV-friendly.”

To summarize, the five points are:

  • FOM takes over each broadcast, and keeps a single (good) director.
  • Picture in Picture is used again, show pitstops/interviews/secondary footage in the inset.
  • Each car has a forward and rearward facing T-Camera, always recording, more onboard footage (entire laps).
  • Constant listing of time gaps all the way down the grid, I don’t want to know how many stops people have done on Lap 3.
  • Widescreen, High Definition.

I generally agree with all of these points. However, it is further recommended to look to NASCAR for production purposes. This is where I part company with our good friends at the F1blog. The reason why I say this is due to the nature of Formula One that makes it a difficult event to televise.

Formula One is technically challenging to produce as a televised event. This is due to the nature of the event which causes us to enjoy the event so immensely. To explain, it is necessary to differentiate Formula One from NASCAR on at least a rudimentary level.

First and foremost, Formula One is a three-dimensional race, whereas NASCAR is a two-dimensional race. By three-dimensional, it is meant that there is depth to the circuit. Depth is achieved in a Formula One circuit by one of two means: 1. Elevation changes and 2. Right-hand turns. Elevation changes cause portions of the circuit to be obstructed from view to the remainder of the race. The classic example would be Monaco. From the Tunnel, to the Casino, to Loew’s: entire portions of the race are completely obscured from view to spectators at the race. Second, right-hand turns: A fine example of this is Malaysia where the circuit wraps around the grandstands. Further, the serpentine of the circuit creates the need to watch across multiple portions of the race simultaneously to take in all of the action while cars slash back-and-forth across the spectator’s field of vision.

In NASCAR, the race is two dimensional. The cars race in a constant level loop entering your field of vision from the left and exiting to your right on the near side and across the way, in the same plane, from the right to the left. There are no elevation changes to speak of, and, generally, the grandstands are constructed to provide an un-obscured view of the entire raceway.

Second, Formula One requires the viewer to decipher the ebb and flow of information related to speed and braking. The nature of F1 requires the spectator to understand that some cars perform better through the tighter, turn-oriented portions of the circuits, while others excel on the straight-a-ways. NASCAR, and the nature of the track, results in a regular flow of information through your field of vision. Passing occurs under the same limited circumstances.

Finally, Formula One represents the pinnacle technical innovation in motorsport. This requires not only the most advanced technology, but the precise implementation of that technology to achieve success. (Just look at Toyota: arguably the largest budget in F1, but poor implementation leading to poorer results.) This creates a disparity among the manufacturers that elevates some within the sport to a superior status. NASCAR, conversely, is homologated racing series which, through regulation, tries to eliminate technological disparities among the teams. Furthermore, a stronger running car in NASCAR moves up through the field to become the lead car. Once in that position, it loses some of its performance superiority due to the fact that it is the lead car. Similarly, weaker cars become more effective against the strong car due to the draft effect. As more cars begin to take advantage of the draft effect, the greater it becomes allowing weaker cars to stay with the lead pack. This just doesn’t happen in F1.

Regardless of anyone’s opinion on that matter, NASCAR creates a tighter field: F1 by nature, creates a disperse field. Cars are spread across the entire circuit with battles for position occurring on all corners and straights. The fact that each team has two cars and the relative position of each is important for both driver’s and constructor’s championship points creates another dimension which exacerbates coverage requirements as well.

All things considered, one must realize that F1 must push the technical aspects of broadcasting to stay up with the pinnacle of racing technology.

  • First and foremost, I agree with the fact that FOM must take over the production of all F1 events. This would create a uniform broadcast and avoid the local bias of television producers for their hometown hero.
  • Second, all broadcasts must be in HD. This would enhance viewing beyond compare. Besides making it easier to see the orange T-bar camera on the #1 team car, we could see the tire tread to determine whether a driver was using intermediates or extreme weather tires ourselves.
  • Third, the use of Internet technologies to simulcast race coverage or even On-demand broadcasting where various channels broadcast real-time onboard race coverage to augment traditional distribution.
  • Finally, the use of dynamic camera mounts which “chase” the cars through turns to give the viewer a better feel of the braking and accelerative power of the F1 cars.

While F1 television coverage has its short-comings, it is still immensely engaging to watch and to appreciate what those drivers are capable of achieving is those technological marvels they call racecars.

NASCAR to Stay on Technology Forefront

Posted by Steve in Technology

October 21st, 2006, NASCAR announced its NEXTEL Cup series will breakdown a long-standing technological barrier. It will replace its current fuel mixture with a state-of-the-art fuel mixture: unleaded gasoline. Further, NASCAR announced it is achieving this transition “to unleaded fuel one year earlier than previously announced as it plans to have all three series run almost the entire 2007 season on unleaded fuel.” [Emphasis added.]

In a similar announcement, the United States Environmental Protection Agency (EPA) issued a press release on January 29th, 1996, stating the EPA was taking the final steps in the (then) 25-year old program designed to phase lead out of gasoline.

[Carol Browner, EPA Administrator] signed a final rulemaking [sic] to eliminate requirements which became obsolete or unnecessary as a result of the ban, including certain recordkeeping and reporting requirements for gasoline refiners and importers. Also, motor vehicle manufacturers will no longer be required to place “unleaded fuel only” labels on the dashboard and on or around the fuel filler inlet area of each new motor vehicle. Deleting these provisions will decrease compliance costs for industry.

In a similar move, NASCAR has announced it will be removing the “leaded fuel only” labels from the dashboard and on or around the fuel filter inlet area for each NEXTEL Cup, Busch Series, and Craftsman Truck series vehicles.

NASCAR’s announcment comes nearly 9 years AFTER the EPA asked the racing series to switch to unleaded fuel. The request letter, containing the now notorious “If Kazakhstan can eliminate lead from gasoline, why can’t NASCAR?” question, reminds us of technological innovations NASCAR has produced for the automotive industry:

  • Five-mile-a-hour-bumpers: the average speed difference between cars engaged in bump drafting

OK, I made that up. But I can’t think of anything that NASCAR has really developed for use in production cars.

So, what was NASCAR’s reason for not pushing the bleeding edge (or the dull edge, for that matter) of racing fuels? According to NASCAR spokesman Ramsey Poston:

NASCAR has “looked into and will continue to look into making the switch to unleaded, but has not been able to find an alternative additive to lead, which lubricates engine valves. Without being able to keep the values lubed, the engines don’t work as well and there would be continual problems,” Posten said. “We just have not been able to find a solution.

In the EPA’s 1996 press release, it stated:

In addition to increasing the octane of gasoline, leaded gasoline also protected exhaust valve seats (in vehicles designed to operate on leaded gasoline) from excessive wear. Both of these objectives are now accomplished without the use of leaded gasoline. Owners of older vehicles with engines designed for leaded fuel may use an unleaded gasoline of comparable octane. For vehicles operating under higher loads, a lead substitute additive may be used, but owners should check with vehicle manufacturers as to which lead substitute additives are appropriate.

To me, this implies that NASCAR is running on out-dated technology. There are plenty of vehicles that “operate under higher loads” and do not use leaded fuel. So, by eliminating the “higher load” exception, we are left with “older vehicles”, i.e., out-dated technology.

“It will be fine,” Richard Childress Racing Assistant Engine Department Manager Danny Lawrence said. “We’ve race-simulated it. We’re definitely going to keep working on it through our research and development department to make sure we won’t have any issues to run 500 miles.”

Well, thank God their R&D department are going to keep working on it!

Hell, maybe with their help, we’ll be able to send someone to the moon!

Q: Why did the West Virginian buy a Pontiac GTO?

Posted by Steve in Technology

A: Because he thought it meant “Going To Ohio”!!!

Ok, it’s a bad joke, but it makes for a great segway: To Homologate or Not to Homologate (not that there is anything wrong with that).

Gran Turismo Omologato (GTO) is Italian for Grand Touring Homologated. It is a moniker that has adorn many great cars, including the Ferrari 250 GTO, and its namesake, the Pontiac GTO. “Homologate” is a fancy way of saying “to make the same.” Sure, the dictionary puts some fancy letters together to help you know how to pro•nun•see•8 it, but it’s all confusing. Them smarty pants start ramblin’ on ’bout the Greeks and ’bout how they’re all homos (not that there’s anything wrong with that). But what do you really need to know about “homologation?”

Well, first, NASCAR is a homologated race series. NASCAR is a nearly complete homologous racing series. What does this mean? It means everthing from the tire manufacturer to the aerodynamic profile of the chassis is dictated and sanctioned by the sporting authority. Formula One was not. At least it was not until the Japanese Grand Prix last weekend. On September 19th, 2006, the existing F1 teams agreed to move forward the engine homologation rule slated to go into effect for the 2008 racing season. So what does “engine homologation” mean?

In an earlier post the “spec engine” was discussed. A spec engine is one that is built to meet a certain technical specification established by the sanctioning body; however, that engine design may evolve around that technical specification incorporating refinements to enhance the engine’s performance while all the time meeting the technical specification requirements. Conversely, a homologated engine is one who’s design is set. The sanctioning body establishes the technical specification; engine manufactures design and build engines which meet that specification; the sanctioning body certifies the engines meeting the specification; and the design is locked for the duration of the homologation period. All subsequent engines must be built to the same design spec as the certified homologated engine.

With the move towards a single tire manufacturer, Michelin withdrawing from the 2007 series, and the early adoption of the engine homologation rules, F1 is moving away from its heritage of pushing the cutting edge of racing and car design. Forward progress is beginning to slow in the name of cost control. These types of regulations place a premium on the Driver’s Championship and detract from the Constructor’s Championship.

While the teams have agreed to implement the homologation rule a year early, they have postponed the implementation of new aerodynamic regulations until 2009. This is potentially due to the fact that they are currently limited through current technical specifications (section 5.3.2) to limited power output ratios and RPM limitations. These specifications are tanatmont to homologation in the first place.

It’s Not a Tribute

Posted by Steve in Technology

This is not a tribute to Michael Schumacher as much as it is funny to see the interaction between Michael and Ralf when they were young. The video clip is in German, but don’t worry, if you’ve seen one “local” news piece production, you’ve seen them all. You can get the gist of what’s going on.

I think Michael says he’s 20 and mentions winning the Formula Konig Series. Ralf says he’s 14. That would make the video circa 1989.
