The twin turbo will smoke everything out there, not sure why no one else is adapting this technology! Well Kia is but then they copy everyone's design and power plant. JS

Don,
I thought I recall reading an article that FCA was developing their version of an EcoBoost engine but it looks like they went another direction with the E Torque system.

They are coming out with both single and dual turbo engines.

The e-torque is just the name, they were going to be called Hurricane.

LINK for 4 cylinder info.
FCA’s new turbocharged four-cylinder engine was internally named “Hurricane,” after a fighter plane and a long-gone Jeep engine. Years ago, Allpar posted the program goals: for one Hurricane to reach 250 horsepower, and for another to beat 300. On November 29, 2017, Jeep released specs on the first one — the efficiency-focused powerplant — and it beat expectations.

The turbocharger is a twin-scroll, low-inertia model, as Allpar predicted a year or two go, with an electronically actuated wastegate; the turbocharger is mounted to the cylinder head for durability. A separate cooling circuit is used for the intake air cooler, throttle body, and turbocharger.

This is the first time that the combined use of a twin-scroll turbocharger, (cooled EGR), Central Direct Injection, and the independent liquid cooling intake of air, throttle body, and turbo have been employed together. This combination of technologies enables the high levels of performance and reduces fuel consumption.

Here is a link for the in-line 6 twin turbo.

I remember back in the 80's they had a lot of turbo 4cyl engines that ran well. Good friend had one. Chrysler was using turbos and GM was using displacement on demand .

An old friend of mine had a late 80s LeBaron convertible with a turbocharged 4 banger and a manual transmission that was a real sleeper.
