Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

Here's the last Dodge Viper

The last Dodge Viper has rolled off the line. Ralph Gilles, FCA's Head of Design since April 2015, posted a photo gallery on Instagram with the caption "So long... #Viper." The gallery includes multiple photos of the Conner Avenue Assembly Plant in Detroit, where the Dodge Viper has been built since 1995. In the gallery, we see a yellow unit with black stripes coming down the line, and Gilles is posing in front of it with Dodge/SRT Head of Design Mark Trostle. The yellow Viper is followed by a red car, with nothing else behind it on the line. That red Viper is "the ultimate last one," according to Gilles, adding that the automaker will be holding onto that unit for the company's heritage collection.

When asked in the comments if the Viper was discontinued because of low sales, Gilles replied, "Not really as it sold well over the last couple of years at a great mix of mostly ACRs in the last 15 months. It has more to do with a new ejection mitigation regulation airbag that simply won't fit in our package." Despite the solemnity of the post, Gilles is upbeat about the Viper in general, saying "The Gen5 had a great 5 model year run and the Viper platform which has not changed that much over the years had a great 25 year run!" He says he has great memories with the car, and that "they are relatively robust so they will be around making memories for generations to come!" Still, we hope to see something that lives up to the Viper's wild, raw spirit come from FCA in the near future.
