Model-year 2013 marks the Pentastar's debut in the Ram 1500. The result is a 42 percent horsepower boost and 13 percent gains in torque and fuel economy, compared with the 3.7L V-6 it replaced.
In select 2013 models of the Chrysler 300 and Dodge Charger full-size sedans, the Pentastar's output jumps to 300 horsepower from 292 horsepower in model-year 2012. But there is no fuel-economy compromise; the cars also top their segment in V-6 highway fuel economy at 31 mpg.
Designed for ultimate flexibility, the Pentastar accommodates transverse or longitudinal mounting; a 6-speed manual transmission and 5- 6- and 8-speed automatic transmissions; plus the full range of drive systems: front, rear, all-wheel and 4x4. Key features include:
- Variable displacement oil pump
- Exhaust manifold integrated into cylinder head
- Direct-mount accessory drive
When the Pentastar launched with the 2011 Jeep Grand Cherokee, it marked the beginning of a new era for Chrysler Group's powertrain portfolio. When all its applications are revealed, it will have replaced seven 6-cylinder engine families.
The Pentastar is the second Chrysler Group engine to record three or more consecutive mentions among Ward's 10 Best. The first was the 5.7-liter OHV HEMI® V-8, a five-time winner from 2003-2007.
The HEMI® also was the last winner to be tested in a pickup, garnering honors under the hood of a Ram 1500 in 2009.
