Race on Sunday, Sell on Monday
Posted on October 13th, 2009 20 commentsLast Thursday, in both of my ENTR200 classes, teams of their own choosing made presentations on Telsa Motors, the relatively new California-based electric car company. In the 9am class in particular, great interest was generated and questions asked by the class. Good job Team 5!
In racing, there is an old saying, “Race on Sunday and sell on Monday.” The thought being, that technology developed on the race track makes its way into future automobiles to the benefit of everybody. Guess what? This is still taking place as we speak only this time, in hybrid-electric technology. It is understandable that race cars need to go as far as possible as fast as possible. This means, among many other things, keeping out of the pits where you’re not going anywhere for as long as possible.
Braking turns the energy of forward motion into heat which is dissipated via the braking system’s pads and rotors, cooled by air ducted over the pad/rotor contact area. Such heat cycling takes place in every instance that brakes are applied for whatever reason – corner, to avoid a collision, or fear. This heat represents wasted energy. Now, Formula One cars, and ALMS, are using something called the Kinetic Energy Recovery System (KERS) that converts this wasted energy into useable electrical energy which is stored, in the case of Steve Pruitt’s GZ09-SH car pictured above, in a 70-pound battery in an extremely efficient manner.
In Pruitt’s case, engineers have calculated at least one less pit stop which normally last from 14 seconds to one minute per race which equates to a massive advantage. While the Prius and other puddle-jumpers are using the same principles, none in general use will be honed to a fine edge like those used where every watt counts, on the race track. Oh, and another thing, the first hybrid-electric car involved in racing was in 1998 when Panoz put “Sparky” on the track and took a second place finish. Panoz BTW, is also a U.S. car company. Hank

The saying is very true and I also noticed that whichever car manufacturer wins a lot in nascar ususally has a sales boost for that year, or it seems like it anyway.

This saying might be true because there is a great incentive for these race teams to develop technology that will help them win. Not only do they have a better chance of winning, but automakers know that some of this new technology will be used in passenger vehicles and thus makes the investment in racing technology a wise decision.

Definitely a win-win; both for the racers (advantage) and for the environment (less energy wasted).

If the kind of attention to detail and need to perform the most efficiently was put into use at some of the failing American automotive companies then they might fare better.

In the downfall of economy, everybody is thinking about reducing costs and raising profits. The whole technology of racing idea may work better when the economy is facing a blossom period,when investors are pretty much looking for places to invest; but when we are facing the recession, I don’t think there’s enough incentive to get the investors to invest in the idea to save energy when braking, while they are still worrying about their own sales record.

This makes for a good strategy. Many people would want to see a product in action before investing in it.

If you can apply the technology to the heat from breaking you should be able to apply it to anywhere in the car that heat is a by-product. I can see future cars using 15 differnt ways to harness the energies that are curently being wasted from cars.

Cool, I think I’ve heard of this idea before. It’s a great idea and useful for cutting time in a race.

Yeah TEAM 5 did a good job as far as the presentation of Tesla motors is concerned. I believe that the usage of electric energy as a substitute of fuel is a great idea that can be successfully implemented in the near future. I guess many people are looking for reducing prices and also increasing the style and efficiency of a car. So I think it should be a good idea to introduce the electric system in cars.

It is ture that in order to make our lives more comfortable and improve the environmental conditions, we should apply the technology from certain areas(like car racing) to our daily life.

I agree that racing like Le Mans advances technology in a timely manner, plus brings real-world application to racing. Regarding Tesla, I’m actually applying for a full-time position it has posted after researching its start-up progress and overall business strategy.

I agree that such a technology could help conserve heat energy produced by the breaks etc and use it more efficiently some place else in the automobile. And I also agree with my fellow student up here that there would many different other sources as well from where something similar can be done. Its for the engineers to figure it out and for the entrepreneurs to exploit it.

The F1 style of KERS would be pretty cool to have in a road car – store up the energy from braking and then use it as some extra boost.
Of course, these things still need some development – it’s debatable if KERS in F1 cars helps or not due to the extra weight and maintenance. Most teams that began using kers dropped it until McLaren was the only team using it. But it does seem to be working well for them now with Hamilton back taking poles and big points. KERS could be great in the future with just some more R&D

That is the smartest idea I’ve heard all year. Simplicity is genius.

If what Zacheriah says is true, GM should really start working on an efficient, new breed of race care that will win.
The energy conservation is awesome idea. I wouldn’t know how, but I would imagine that the emissions expelled in the exhaust could somehow be collected and transformed into something useful.

I know mercedes was looking into this a little while ago, but its a great idea and would be cool to be on the road and makes sense
ps. Team 6 Tesla presentation was better!

This is a really awesome idea. It’s important to protect the environment and natural source nowadays.

The Telsa Motors car seems very innovative. I didn’t know wasted heat energy can be stored to be used as hybrid electric energy. Did they come up with this idea just to reduce costs or just for the technology? Well, there must be competition among automobile industries. But, the surprising things are their cars show much faster and safer ways to race! I wonder the car’s durability in racing. As Chris mentioned, I think we can also apply to our cars. Maybe some of the cars can use hybrid electric energy as well as algal fuel at the same time.

Too kind Hanks, as far as Hybrid Electric car goes, eventually fuels are going to run out. Like it or not, tis the fact. Now there may be renewable fuel source out there, but why use fuel if car no longer requires fuel. With nowadays technology, cars can get up to 300 miles+ with one single charge. Eventually, with enough investment, electric car has its potential to be the car of tomorrow.

This is an interesting idea I didn’t know they did this…I guess it’s a good collecters car too…
