The impact of Toyota's expansion next season into Busch and Nextel Cup competition is being felt in the engine development departments of the three existing NASCAR manufacturers – General Motors, Ford and Dodge.

Because Toyota had to build a brand new engine that would allow it to compete in the Craftsman Truck Series, the manufacturer had the luxury of working with a clean sheet of paper. And despite working within NASCAR rules, Toyota engineers produced an engine that potentially gives the manufacturer a competitive edge.

Without getting lost in pages of technical jargon, the bottom line is that Toyota designed an engine that was lighter, stronger and potentially able to produce more power than anything that the other three either are currently using or were planning to build.

Using their very successful Toyota Tundras program as laboratories on wheels, Toyota engineers could examine hours of data on the performance of their truck engine and then incorporate it into their upcoming Nextel Cup engine.




With Toyota preparing to submit a new engine for Cup competition, NASCAR officials – in what may have been an attempt to appease the other three manufacturers – allowed Chevy, Dodge and Ford the opportunity to submit new engine block designs as well.

Each of the three took a different course by choosing to design a new engine, making wholesale changes to a current engine or modifying individual parts.

Toyota's engines will come from the same place that the GM, dodge and ford engines come from: nasacr approved engine builders. I know that Robert Yates racing used to make engines but I can't remember any of the other engine builders. The engines in nascar bear no resemblance whatsoever to the engines in their street cars aside from the number of cylinders and basic size. In fact, GM is makes a V-8 of similar size to the 5.7L (350 cu in) engines used in nascar. Ford makes a 327 cu in engine for their pickup trucks. Ford put the 351cu in engine in some of their cars about 30 years ago but still used an entirely different engine in their nascar cars. As far as I know chrysler has never put a 350 cu in engine in their road cars until the current 5.7L hemi, they always made and still do, 340s and 360s. The old legendary hemi came in the 340 size and a 427.
All of the parts on a nascar cup car have be built by approved racecar builders and under approved specifications. This is done to keep the racing close which makes for a more entertaining race. As it is now the only difference between the manufacturers's cars is the front and rear bumper design. So, really it doesn't matter whether Ferrari, Porsche, Hyundai or Honda want to get into nascar too; they will all have to use the same approved parts that the other teams use and their cars would look alot like the others.

toyota uses an engine thats a 356 c.i. engine in their off road tundras. Johnny grieves has been using, and helping to devolop this engine for years.If any of you have been to a CORR racing event, then you can also hear that that thing will turn a good 1000 rpm higher than the ford and chevy.Johnny Grieves is the pro4 wheel drive champion.He also had the smallest engine in the class. they have a weight to cubic inch rule.I know some people that work for potawatomi racing, and they will only say 800+ h.p.
It is TRD building these engines, and they will , and have put alot
of time and resources . I am not a toyota fan, but they will have some pieces in place relatively soon.

Actually, the engine has been available in the Tundra for years. The difference in the cubic inces and intake manifolds. NASCAR has certain specification that the manufactures have to meet. The only manufacture that has not made any changes to their motors this year is the Chevy. Ford has developed a new intake manifold to increase their hourse power to match that of the Toyota.

What? not available to the public? You mean NASCAR isn't really stock car racing? Maybe they should actually change the name to a more appropriate NARGIAC: National Association of Rednecks Going In A Circle.

Not sure what they are running, but I do know that Toyota owns Lexxus which some have v8s. Maybe they had to get Nascar's approval for that motor.

Actually, Toyota Racing Development builds the engines for all Toyota teams. Toyota is very involved with building the chasis and other things for teams.

For their first year on the circut they are just going to double up two hybrid synergy drive engines in their cars... They wont have much of a top speed, but they will never have to stop for gas... LOL

I am only kidding, I am a huge nascar fan, but I think your question has already been answered...

The Tundra has a V8 that has been in production for several years. That is where the engine comes from and it can be bored out for the proper displacement. They did not design an engine from scratch just for NASCAR.
