The planned Dodge Dart SRT will be enabled by a brand new series of four-cylinder engines , which some insiders say are a joint effort of Chrysler and Fiat, merging aspects of existing designs from both companies.

Originally, the engines, dubbed “Hurricane” after military aircraft (and likely referencing vintage Jeep engines as well), were thought to be merely turbocharged versions of the existing 2.0 or 2.4 liter powerplants. However, sources now believe these will presage or be part of a brand new engine family shared by Chrysler and Fiat.
Chrysler was once the largest manufacturer of turbocharged gasoline engines, culminating in the Turbo III (224 horsepower from a 2.2 liter four-cylinder, in 1991) and Turbo IV (which had the first production gasoline-engine variable-nozzle turbocharger).
Chrysler tested two-stage turbocharging (illustration on right) in a Department of Energy project, with a small and large turbo to reduce lag and increase power. Insiders say this is not likely to make it to the production engines; instead, a single twin-scroll turbocharger seems to be planned. It is likely to be relatively small but have a very high rotation speed, compared with past Chrysler turbochargers .
