I'm not a fan of "pulse and glide" and this paper requires close reading. A vehicle model was used along with some benchmarking so I'll be looking closely at the model and results. Looking at Table 4, "30-40 mph, 20 seconds of acceleration" shows their field test had a 25% performance improvement over the equivalent steady state, 35 mph cruise speed. My field testing of 25-40 mph, 33 mph cruise speed showed only an 11% improvement. We're off by a factor of two so the I'll be looking closely at their protocol.
Which vehicle/s was/were tested for this report?

Ben came home from the NY Auto Show with an interesting tidbit from the lead engineer on the Ford Fusion hybrid: he said the drivetrain was "optimized" for P&G. Not sure if he meant compared to non-hybrid drivetrains, or compared to other hybrids.

Ben's trying to track down his contact info. That's one bit of info I'd like clarified.
