EcoDiesel V-6 Scores “Three-Peat”

In major league sports, the term “three-peat” is reserved, most-deservedly, for those teams which have three consecutive championships. And now the term can also be used when referring to the 3.0-liter EcoDiesel V-6 — one of Wards 10 Best Engines for 2016.

For the third consecutive year the EcoDiesel has been named to the prestigious list – the longest tenure of any 2016 honoree. This also marks the second straight year the EcoDiesel has been the lone representative of clean diesel technology among Wards 10 Best Engines.

“We are never content to rest on our laurels, so our engineering team worked overtime to make a great engine even greater,” said Bob Lee, Vice President and Head of Engine, Powertrain and Electrified Propulsion Systems Engineering. “For model-year 2016, customers who choose our 3.0-liter EcoDiesel V-6 will experience more of the attributes they were seeking when FCA US became the first automaker to equip a light-duty pickup with clean diesel technology.”

FCA US powertrain engineers introduced new strategies to better manage combustion in the 3.0-liter EcoDiesel. The U.S. Environmental Protection Agency (EPA) rates the 2016 Ram 1500 pickup at 21 miles per gallon (mpg) city, 29 mpg highway and 24 mpg combined.

Further, FCA US engineers developed additional controls to shape torque demand. The outcome improves part-throttle performance during rolling pedal tip-in, as well as acceleration from stop. The 2016 EcoDiesel’s enhanced response affords greater control of the engine’s prodigious torque for a driving experience that is smoother and more comfortable.

No Easy Layup
“The 3.0-liter from FCA was one of three diesels in pickup trucks we tested this year for Wards 10 Best Engines, and we expected a tough fight among them all,” said Tom Murphy, executive editor WardsAuto World. “But the Ram 1500 proved superior and continues to impress us with ideal measures of power, torque, refinement and luxury-car smoothness.”

2016 Jeep® Grand Cherokee SRT Night

The 3.0-liter EcoDiesel V-6 also is available in the 2016 Jeep® Grand Cherokee, the most-awarded SUV ever. When so equipped, the Grand Cherokee is rated at 30 mpg on the highway, which is best in class.

In addition, the EcoDiesel-powered Grand Cherokee boasts unsurpassed driving range of more than 730 miles. In the 21-year history of Wards 10 Best Engines, seven engines produced by FCA US and its predecessor companies have accounted for 16 awards. The 5.7-liter HEMI® V-8 and 3.6-liter Pentastar V-6 accounted for six and three trophies, respectively. The remaining winners were:
