Nothing official so far, but according to GM's and Ford's comparison engines, the 2015 Chrysler is a heavy drinker, despite its very low drag coefficient (0.27, compared to 0.34 for a 2014 Chevy Malibu). With a less powerful engine than most other mid size cars (184hp for a 2.4L 4-cyl), it drinks 1.5-2L more every 100Km than a Malibu, Sonata, Accord. That's appaling. It's the kind of numbers one would expect from a 2006-2008 new car with a comparable displacement, not from a 2015 model. Their 3.6L V6 Pentastar isn't better. It drinks ~1L more per 100Km than the 3.5L V6 in the Ford Taurus, which is a much bigger car.
We'll wait for the official numbers, but it doesn't look good. Too bad. It would have been good for Detroit if Chrysler could have hit a home run for once.
