This article begins with yet another discussion of the possible return to a spoiler. But the good stuff is towards the end so read through it even if you are up to date on the spoiler issue.
Using the alternator as a form of traction control? Who says Nascar is "old school" technology?

Some of last season's tricks are finally being revealed....but what's up the sleeve for 2010?

NASCAR teams are testing this week at Texas World Speedway, to see how that planned new rear spoiler might work on their Sprint Cup cars, according to stock car crews.
NASCAR officials are tentatively planning to change the rear wing on the Cup cars to a more standard flat rear spoiler, beginning either with the Bristol 500 March 21 or Martinsville 500 March 28. But it will be the Cup races at Phoenix April 10th and Texas April 18th that would be the major test of the new spoiler, which is designed to add downforce to the cars and make them handle better.
Drivers have complained that the car-of-tomorrow -- designed as a low-downforce machine, with the idea that that would bringing driver talent to the fore -- doesn't have enough downforce.
Drivers like downforce, no matter what the venue. And the current car-of-tomorrow has significantly less downforce than the old standard Cup car.
Fans too have expressed their displeasure with the winged car.
There are more changes coming too, apparently, with Daytona cars possibly sporting a new 'shark fin' on the rear deck, to make them more stable when they get sideways. The 'shark fin' would be a three-inch tall fin running from the top of the rear window to the rear wing, according to crews. How that might be tested is unclear, since NASCAR has banned testing at Daytona and Talladega.
While the long-standard flat rear spoiler on Cup and Nationwide cars has basically been just a $5 piece of steel, bolted on to the rear deck, the new flat rear spoiler will apparently be another 'over-engineered' piece by NASCAR, sold to the teams by NASCAR and installed at each track by NASCAR officials.
So change is finally coming to the long-criticized car-of-tomorrow. But there are no changes apparently planned yet to the snowplow nose.
And it's unclear exactly why these changes are suddenly being unveiled, rather than say late last fall when teams might have had a chance to offer some input, instead of having changes handed to them just weeks before the new season opens.
Another change, though not one mandated by NASCAR, is striking: the lowly alternator.
Now you, the street-car consumer, could buy an engine alternator for maybe $30 or so for your family sedan. But NASCAR race car alternators are a bit more expensive: five years ago a NASCAR alternator would run about $500. Last season Cup team alternators were being priced at $2900. This year -- the price has jumped to $6,000. Why? Because the car-of-tomorrow apparently generates so much heat under the hood that teams have been having electrical failures.
Race car electronics is big business among NASCAR engineers these days, in more ways than one -- Want legal traction control, for flat tracks like Martinsville and Phoenix? If you do it right, you can rig your car's electrical system to where it has an electrical 'kill' system in the corners, with less voltage going to the engine, to keep the car from spinning the rear wheels coming off the corners. Want to see it in action? Check the exhaust from some cars in the corners -- with those huge streaks of flame.
And it's all legal.
Another trick teams are finally catching on to -- remember some of that strange black smoke coming out from under some cars last season? The smoke that TV guys thought might be tire problems?
Well, apparently some engine men have figured out a way to trick up their exhaust headers, legally, with tiny holes, which effectively add air to the exhaust gases and turn the exhaust system into something of an engine 'turbo-pump,' sucking air through the engine system faster, creating more power.
Of course, those were some of the top tricks for the 2009 Cup season. And now it's 2010..and it may take just about that long to figure out what new tricks all these team engineers have come up with for this new season.
