BorgWarner’s products boost performance and efficiency in 2011 Jeep Grand Cherokee

by Bill Cawthon on

BorgWarner is telling the world about the fact it supplies the engine timing system and transmission components for the new 2011 Jeep Grand Cherokee, the first vehicle to be equipped with Chrysler’s new Pentastar V6 engine.

In a company press release, Timothy M. Manganello, Chairman and Chief Executive Officer, BorgWarner, said, “Nearly 20 years ago, Jeep pioneered the premium SUV segment. We are pleased that Chrysler Group has chosen BorgWarner technologies for the Jeep Grand Cherokee and the company’s most advanced V6 engine.”

Compared with its predecessor, the new 290-horsepower Pentastar engine improves torque by 11 percent, horsepower by 38 percent and fuel economy by 11 percent, enabling the Grand Cherokee to deliver up to 23 mpg.

BorgWarner Morse TEC’s timing system with silent chains delivers superior performance, industry-leading noise, vibration and harshness (NVH) characteristics, precision timing and durability. Joint development between Chrysler Group and Morse TEC engineers optimized the Pentastar system’s performance and resulted in lower chain tensions as well as improved durability, NVH and engine efficiency.

In addition, the 2011 Grand Cherokee’s five-speed automatic transmission features high-energy friction plates and sprag one-way clutches supplied by BorgWarner Drivetrain Systems.
