In August we read a frankly devastating report that the 6.2-liter and 6.4-liter HEMI V8s were to be killed off for good in 2018. From that point forward, all Fiat Chrysler performance products will be powered by a twin-turbocharged V6 or twin-turbocharged four, the rumors indicated, and we may have a bit more information on the twin-turbo six.
According to reliable Fiat Chrysler Authority sources, a twin-turbo version of Chrysler’s 3.6-liter Pentastar V6 is in the works. The engine will likely replace the current 6.2-liter Hellcat V8 and 6.4-liter HEMI V8 found under the hood of SRT performance products and deliver similar performance but with the benefit of added fuel economy.
The decision to switch to a twin-turbocharged V6 for future performance applications is hardly a surprise. General Motors has been hard at work developing twin-turbocharged V6 engines and currently uses them in its Cadillac portfolio, while Ford led the way with its 3.5-liter EcoBoost V6 – first introduced in 2010. FCA’s company-wide fuel economy is lower than both Ford and GM, so it’s eager to get in on the turbocharged action.
We could see the twin-turbocharged Pentastar being used in the replacement for the Dodge Charger and Challenger and also the rumored performance crossover from Dodge. The HEMI is expected to die off at the end of the 2018 model year, so we’d expect an announcement in regards to Chrysler new turbo Pentastar to come about shortly before then.
