The Wall Street Journal is reporting that the next-generation Chrysler 200 will show off a host of improvements, including a fuel economy rating of 38 miles per gallon on the highway. That's a jump of seven mpg over the current model, and much of that efficiency can be chalked up to a new nine-speed automatic transmission. Expect to see the revised 200 show up on dealer lots in the first quarter of 2014. The news came courtesy of a dealer meeting in Las Vegas, where Chrysler unveiled upwards of six new vehicles set to arrive within the next year and a half. Chrysler reportedly also showed off its subcompact 100, said to be based on the Dodge Dart . Other vehicles shown at the dealer sit-down included a four-door version of the Fiat 500 , the replacement for the Jeep Liberty and a new small Jeep as well. Both dealers and the manufacturer are keeping the rest of their secrets to themselves at the moment. Stay tuned.
