Future Chrysler, Dodge, and Jeep Powertrain: Engines and Transmissions

Hurricane: turbocharged four cylinders

hurricane engineRalph Giles announced a “new family” of four cylinder engines to appear in late 2016, during an Autoline After Hours appearance.

The Hurricane 2.0 is likely to be widely used, but is probably a stopgap before a completely new cross-FCA four cylinder engine lineup. The Jeep Wrangler is to get a 300 horsepower version, according to Automotive News, and they will be the base engine for the revised Charger and Challenger in 2021 or so, according to oh2o.

Fiat is working on small engines with three and four cylinders, ranging from around 65 to 185 hp (with turbocharging). The “medium sized” Hurricane engine from Chrysler is expected to be a 2.0 liter with 240 horsepower in the standard version and 300 horsepower in the hotter version.

Pentastar V6 engines: upgrades, V8

Pentastar V6 engines were to spawn a 4.8 liter V8 but that seems to have been dropped or postponed. An initial power boost came in 2015, but another is due soon, with direct injection and parasitic loss reduction. There will almost certainly be changes to the valve setup and cylinder heads. There are rumors of a supercharged 3.2 and turbo 3-liter engines developed by Chrysler, and they still appear to be on the way, but are still some way in the future.

Other gas engines

An updated Apache 392 Hemi and Eagle 5.7 Hemi with higher power ratings were both set for calendar-year 2015, according to several sources, but plans change and neither has shown up — it’s possible both efforts were canceleled or delayed. The company may end up with Hemi V8s for trucks and key cars, and turbo V6 power for other cars.

Eight speed and nine speed automatics

ZF’s eight speed automatic transmission for rear wheel drive cars and nine speed ZF front wheel drive cars continues to spread across the line; a second generation is being used by pricier cars from FCA and others. The transmissions can be used with stop-start systems and hybrids. Both have shift times below the limit of human perception, and can shift multiple gears at once; they can carry numerous shift maps for different uses, and Chrysler seems to be falling behind in programming them.

ZF 9-speed automatic

The ZF is used by Audi, Maserati, Rolls-Royce, and others as well. Transmissions. The internally-made Chrysler versions have some differences due to different factory layouts and needs, with most of the internal parts reportedly not being interchangeable (845RFE, ZF HP8928TE, ZF HP9).

Diesels

The Cummins B-series straight-six diesel is still planned for future Rams. A Fiat diesel (possibly the L424) is reportedly being tested for US certification in Wrangler though they may use a newly revised VM 2.8 liter four-cylinder diesel in the US.

Hybrid cars, electric cars

A hybrid minivan is coming, and other cars use a Chrysler-engineered start-stop system which shuts off the engine when the car is stopped. Chrysler is supposedly Fiat’s headquarters for electric and hybrid car development, with an electric Fiat 500 already launched. CNG is available on Ram Hemis for fleet use.
