2017 Chrysler Pacifica Hybrid PHEV minivan EPA-rated at 84 MPGe in electric-only mode; role of eFlite dual-motor/one-way clutch strategy

Green Car Congress

No other minivan has ever come close to this rating. (As In addition, the EPA gave the all-new minivan a rating of 10 in its Green Vehicle Guide. This marks the first time a minivan has achieved a 10—the highest possible rating—in this category. The MSRP of the non-hybrid Pacifica minivan is $28,595.

ORNL study quantifies fuel economy costs of common driver practices and vehicle alterations

Green Car Congress

They presented their results in a paper at SAE 2014 World Congress in Detroit. In addition, two minivans were subjected to coastdowns to examine the similarity in derived coefficients for two duplicate vehicles of the same model. The SUV, a 2009 Ford Explorer with a 4-liter V6 engine, was also tested while towing an enclosed trailer.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. Source: Borgwarner. Click to enlarge.

Achates Power building 2.7L opposed-piston light-duty engine; exceeding CAFE 2025, Tier 3 targets at lower cost

Green Car Congress

In 2014, we presented a peer-reviewed technical paper, Meeting Stringent 2025 Emissions and Fuel Efficiency Regulations with an Opposed-Piston, Light-Duty Diesel Engine, at the SAE World Congress showing how we were able to meet CAFE 2025 regulations in a Full-Size Truck. A high trapped temperature results in high exhaust gas temperatures.
