Chrysler plans for 400+ hp V6

by David Zatz on

By 2014, Chrysler could have a V6 engine pushing out over 400 horsepower, according to charts in the five year plan. A three-liter version of the Pentastar V6 with dual turbochargers is charted out in the plan at around 425 horsepower, the same as the old 426 Hemi V8 and similar to the current 6.1 liter Hemi V8. While the 6.4 liter Hemi V8 would push out more horsepower, the V6 would, even with a single turbocharger, match the 5.7 liter Hemi V8.  Torque has not been discussed.

The Pentastar V6 was designed to have variable cam timing and direct injection. It will debut (without direct injection) on the Jeep Grand Cherokee around May 2010. The higher-horsepower varieties discussed in the plan would include MultiAir and would be released by or in 2014. Before then, the Pentastar would have replaced all other Chrysler V6 engines.

A turbocharged version of the World Engine with direct injection also appears on the chart putting out around 300 horsepower, more than the standard 3.3 or 3.6 liter Pentastar V6. Fiat’s 1.4 liter engines were shown at a respectable 150 horsepower with turbocharging, 100 hp without.  Chrysler has already sold a turbocharged version of the World Engine, in the Caliber SRT4.
