Another Thanksgiving is upon us, and once again I would like to thank you, my readers, for your continued support of About.com and the Cars site. I am one of those lucky people who gets to do what he loves for a living, and without you, the folks who read this web site, that simply wouldn't be possible. Please accept my most gracious thanks and my sincere wishes for a happy, healthy and safe Thanksgiving.

I've taken to posing car-related questions on Thanksgiving. In past years, we've discussed influential cars and bad cars. So this year, I have a simple question: What do you think was -- or is -- the best car ever made, and why? Click the comments link below. I can't wait to see your responses! -- Aaron Gold

So I'm back from our 24 Hours of Lemons race at Thunderhill, and the Cadillac Escalade Hybrid turned out to be an impressive tow vehicle. It struggled on some of really steep hills and stopping the rig was a bit of an adventure -- note to self, check the battery for the electric brakes -- but the Caddy was comfortable and, more importantly, stable. As for fuel economy, I averaged 14.2 MPG with the trailer hooked on -- not as good as the diesel-powered Dodge, but not a bad figure at all, considering the regular V8-powered Escalade can barely manage that when running light.

OK - on to the race! We created a completely new theme for the 633 CSi: Our German homage to Richard Petty's famous Superbird, complete with huge nose and ridiculously tall wing. We dubbed it Der Uberbird, and it was a big hit with the Thunderhill attendees, especially the kids, who recognized it as The King from the movie Cars. Our nose and wing may not have done much for the car's handling, but our cut springs and thicker anti-roll bars sure did, and the Uberbird was a lot more competitive this time around, despite our so-so driving skills. We finished mid-pack -- 87th out of 160 cars. But more importantly, the Uberbird was still running at the end of the race (although the shift linkage was broken and it was stuck in drive), despite a couple of off-track excursions, including one by yours truly, and the entire exhaust system falling off twice. The most important thing is that we all had a fantastic time. I've said it before and I'll say it again: If you have an inkling of wanting to race at Lemons, then you should totally do it. Find out how at the official 24 Hours of Lemons web site.

I've added a whole mess o' photos to my Team Unknown Fluids 633 CSi photo gallery; photos of the Uberbird start on this page and race photos start on this page. Special thanks to teammate Jeremy Jozwik for letting me use his spectacular race photos. -- Aaron Gold

Before we get to the CTS Coupe, a quick note: I'm on my way back from our 24 Hours of Lemons race. Things went well -- we actually finished! I'll tell you more about the race, as well as how the Cadillac Escalade Hybrid did on fuel, in a day or two.

Today, we have other news from Cadillac: Photos of the production version of the 2011 Cadillac CTS Coupe. To be honest, the photos don't look terribly exciting to me, but I've seen the concept version in person and it's a stunner. I'm thinking (and hoping) that the production version looks significantly better in person -- I think this is going to be one of those cars that has to be seen in person to be appreciated. Caddy also released some tech specs, and they look great: The CTS Coupe will be powered by a 304 hp 3.6 liter direct-injected V6 with a choice of 6-speed manual or automatic transmissions, and a "V" version is in the works. Have a look at my 2011 Cadillac CTS Coupe photo gallery and see what you think. -- Aaron Gold

As you read this -- well, provided you're reading it after 6:30 am or so Pacific time -- I'll be towing our race car (and I use that term loosely) in the general direction of the 24 Hours of Lemons race at Thunderhill in northern California. Now, last time I towed the car to a race, I did it the old fashioned way: With a Dodge RAM 3500 pickup powered by the famous Cummins turbodiesel. The Dodge drove as if I was towing a load of feathers, and returned a respectable 16.7 MPG.

This time, I'm trying something a little different -- I'll be towing the car with a 2009 Cadillac Escalade Hybrid. GM says the four-wheel-drive Escalade Hybrid will tow up to 5,600 lbs, which is just a few hundred pounds more than we need, and its 14,000 lb gross combined weight rating (GCWR) means we can add another ton or so of passengers and cargo without risking a Darwin award. EPA fuel economy estimates for the two-wheel-drive Escalade Hybrid are 20 MPG city/21 MPG highway. I'm driving an all-wheel-drive version, and the EPA estimates are... well, I actually don't know, because the extra weight of the all-wheel-drive system pushes the Escalade into a higher weight class and makes it exempt from EPA testing. (You'd think Cadillac would publish the numbers anyway, as a point of pride.) Whatever the numbers are, they've got to be better than the non-hybrid Escalade's estimates, which are -- Prius owners, you'd better sit down for this one -- 11 MPG city and 14 MPG highway.

So far, I've been averaging 18.8 MPG in mixed driving with no trailer but about 200 lbs of race-related cargo in the back. We'll see what a trailer and a crappy race car do to the Escalade's fuel economy. Any guesses? -- Aaron Gold
