Herbie would win of course!!!

That's a tough one!  I mean time and space are linked, so one has to presume that the delorean (assuming it's the actual time-travel Delorean) could just go there.  Or at least jump back in time once there.  The flintmobile has fewer moving parts to break down, and may possibly even be there already, waiting to be dug up (young punks having pushed it into a tar pit.)

On the other hand, KITT and the General Lee actually run on "cool", (unleaded of course), and wouldn't have to stop for gas.

I voted for KITT and General Lee.  KITT has weapons and armour and could destroy all the other competition, and the Duke boys would know all the back roads to get to the finish line.

The Delorean's time travelling capability made it a serious contender, but if KITT blew it up it wouldn't be travelling anywhere or anywhen.

I'm going to go with batmobile, from the movies and not the tv show.  It would have even more weapons than kitt and and would make up the difference easily because of its... um... well... JET ENGINE!

Ya, but that depends on who's driving the firebird.  I assume the 2 vehicles have to finish as a team, and the Batmobile would wayyy outpace a firebird being driven by James Garner.  If it was the Bandit (Burt Reynolds) on the other hand, you would have a serious shot at convincing me (Bandit obviously has the experience and contacts to pull it off).  Unfortunately, Rockford was specified.

It should also be mentioned that Herbie/S&H could have a problem as a team, because that Gran Torino had an unfortunate tendency to pull toward any cardboard boxes in it's vicinity, and crash into them (especially if they were located in a warehouse).

KITT and the General Lee have also demonstrated the ability to jump over almost any object in their path, so it could almost be a straight shot for them.  I think they're the best overall team.

If it's a relay on the other hand, what are the rules?  Do both vehicles have to cover the same amount of ground?

The question didn't say as a team, it said as a tag team.  And even if it's the same amount of ground Batmobile and firebird would win.

Hmm..  in my mind, the only way this race could be tag team would be as a relay race.  So one car would traverse the first half of the race, and at some checkpoint, the other car would take over till the finish line.

As such, even though batmobile has a jet engine, the other leg of the race has to be run by James Garner.  I'm pretty sure the Duke boys could beat Rockford in a race.

According to web sources(1), the top speed for the Batmobile (with Jet Engine) is roughly equal to top speed for KITT at an excess of 200mph (averaging out various numbers, and being generous to Batmobile).

I think you're being generous to KITT.  I beleive that the duke boys would beat Garner, (though not by much) I think the batmobile would definitely make up the difference against KITT.

Did you read the links?  Top speeds for Batmobile ranged from 110 to 200 mph.  Top speeds for KITT were 200 to 300mph.

Ok, I've seen it...A pontiac trans am going 300 mph??? come on.  The one site says the batmobile could get up to 220.   The structure of the trans am would not be as stable as the batmobile.  So if the terrain includes off roading certainly that would support the batmobile... and even if there were no off roading required the batmobile could easily take a more direct route at some points.  

I think you're getting a little too "real-world science" on this one.  We've seen KITT go 300mph in the show.  That should be proof enough, whether or not a trans-am should be able to handle it.  We could explain it with KITT's enhanced structure and shell.

I was going on real world, but I'd like to change my answer.... our old 1991 Nissan sentra, which had liquid oxygen and nitrogen tanks attached to the rear wheels and when the muffler sparked off the pavement that would set off the rocket which was in the trunk of the nissan.... (you never saw this because it was illegal and I didn't want to get you in trouble... two words plausible deniability) the other car is our 1992 mercury topaz... after it was written off in July 99... because it was actually MORE aerodynamic after the accident and was equiped with a hyperspace wheelbarrow to the rear axle in leu of wheels... that combo would beat the others.

The answer really depends on your definition of 'tag team race' ... If the meaning is a traditional relay race, where each member travels the same distance with whichever team has the lowest time, then it is a no brainer, the Delorean and the Flintmobile take it hands down - the Flintmobile starts the race, at the halfway point the Delorean takes over, hits 88 mph and travels back in time far enough to ensure victory.  
If it is a tag team like in wrestling, the Delorean simply starts the race by going back in time and finishes without the help of the Flintmobile at all.
That being said, if it is a race where both parties need to cross the finish line, there is another issue entirely and the '91 Sentra / '92 Topaz team would take it hands down

Well, the way I envision it was as an Epic 8 hr tag team relay race. A fun way to race as you can socialize between laps, but you must remember to hammer out your laps to pull gradually away from your competitors! This race is based on the Madison style tag team racing in which the team works to complete a number of circuits/laps and uses a sling-shot technique to change positions. The course would consist of 6 distinctive laps with their own challenges (to follow tomorrow). The relay race would involve bursts of speed, dangerous maneuvering, and a high level of endurance.

Contest Rules:

Each team must intend to consist of 2 cars and 2 drivers.

Each car must complete the equivalent miles of three laps and each team must comple the 6 lap course within the 8 hour time limit to get an official standing.

A minimum speed of 90 km/h must be maintained.

Slipstreaming, slam and bump drafting is permitted.

Slingshot position changes can only occur twice per lap, with no more than five changes for the race. Slingshot position changes must take no more than 60 seconds and must occur at full speed or a time penalty is added to the overall score.

All tires cannot leave the road for more than a period of 4 minutes and two tires can leave the road for a period no greater than 10 minutes. Teams that are able to reach pink floating go-go balls in jumps loses 30 sec off  overall time.

No course cutting. This includes all switchbacks.

Teams that do not make it to the relay exchange point, by the official cut-off time (78  minutes), may begin the next leg 20 minutes after official cut-off time. If this occurs twice, the team is disqualified.

Teams driving vehicles that were not on a hit TV show or Movie are automatically disqualified and crushed for the amusement of the fans unless they race completely in reverse.

I definitely have a different vision of this race which would see the two team members being split up at the start and the two racing literally across the country (as all shows were based in the US, I will use US destinations) say from Virginia Beach to San Francisco, roughly a 44 hour trip (at normal driving speeds).

The first driver would start in Virginia Beach with the second waiting somewhere near the middle, say Beaver Crossing, Nebraska.  When the first driver made it to the mid point, then the second driver would leave.  The route would not necessarily be determined, but required 'stops' along the way would be, with pictures proving you were there - say the Owl Club in Battle Mountain, Nevada, playing a game of Keno for example - which would add some route planning and timing (some locations may not be open to the public 24 hours a day) to the adventure.

I know most of you are probably thinking that this sounds a little too much like 'Tail Lights Fade', and it might, but it's still what I had in mind for this race.

If it is Madison style racing however, I think the Sentra / Topaz team could still win it going in reverse the whole time

I'm not familiar with which TV show/Movie that the Sentra or topaz were in??

I think that at the very least, we can say that the 'no course cutting' rule eliminates the Delorean's advantage.  I can't think of a more blatant short cut than to cut across time...

The sentra/topaz were in the reality show "Albert, the man of ages..."  

I think a straight forward race, like out of cannon ball run, would make the batmobile champion... as it has the most hardware to take out opponents.

Well Hawkeye, you'll have to post your own poll, where you can make up whatever rules you feel are necessary to ensure Batmobile's victory.  

I WILL!

Do you think this car team would beat all the others?

Not even if they parked them an inch from the finish line and it was downhill.

See they would win because.... because they could be PUSHED over the line... nothing was EVER said about human power!!!  HAHA HA I wins..

Yup, you're a real winner.
