Lee Iacocca's very first Dodge Viper RT/10 nets $285,500 at auction

The first 1992 Dodge Viper RT/10 to roll down the assembly line, which was snapped up by Chrysler chief Lee Iacocca, yesterday hammered at the Bonhams auction in Arizona for $285,500, more than double the pre-sale estimate. According to a history of the car published by the auction house, Iacocca, in his introduction of the Viper to the press, pointed to the car on stage and said, "This one right here is mine." That historic Viper, with serial number 001, has never been available on the open market, as Iacocca kept the car from new until he passed away last year. The car has been driven just 6,200 miles and was being sold by his estate. Other Lee Iacocca cars offered at the same sale fared less well. A 1986 Chrysler LeBaron Town & Country convertible — the ultimate expression of Iacocca's company-saving K-cars — with 20,500 miles on it sold for $19,040. That's less than the $20,000 to $25,000 the auction house had estimated the car would bring. A third car from the former auto executive's estate was a customized 2009 Ford Mustang. The pony car was one of a limited run of 45 Iacocca-branded custom Mustangs, which were reworked by Metalcrafters and sold by Galpin Ford in Los Angeles. The Iacocca Mustang, never titled and with 220 miles on it, hammered for $49,280.

Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.

Ram exec: first 30-mpg pickup truck will 'win'

It is totally possible, today, to take the Ram 1500 EcoDiesel pickup truck, load it up with gear and people, and drive it from Texas to Michigan while getting 38 miles per gallon. We know because we did it. Officially, though, the 1500 gets just 20 mpg combined. A more impressive number is the 28 mpg on the highway. Bob Hegbloom, the Ram brand director, thinks that there's a more important fuel economy target to hit: 30 mpg. Whichever truck company can manage that feat, he recently told Automotive News, "wins." It's kind of an obvious thing to say, but in the 1500 with both the EcoDiesel and the V6 Pentastar engine, Hegbloom said, "fuel economy is so important." Hegbloom didn't promise that the next EcoDiesel truck will manage to get on up over the 30 hump, but he did say that Ram is not sitting still when it comes to fuel economy. "I just want to have continuous improvement and to keep gaining every day," he said. "We sat still in the past and it doesn't lead to a great place."
