Great start, but long road ahead

I just returned from the Center for Automotive Research (CAR) Management Briefing Seminars in beautiful Traverse City, MI, and don't have much electric vehicle (EV) news to report from there. Instead, the seminars were focused on getting more diesels into the U.S. and increasing the efficiency of liquid-fueled vehicles.

The Advanced Powertrain Forum session, for example, was led off by Ford global powertrain engineering VP Barb Samardzich, who talked mostly about power and torque upgrades for Ford's new heavy-duty diesel V8...important to work-truck customers, not so much to the rest of us. She was followed by Dr. Johannes-Joerg Rueger, senior engineering VP, diesel systems, Robert Bosch LLC, who touted increasing acceptance of U.S. buyers to diesel cars.

Then came Larry Nitz, General Motors' hybrid and powertrain engineering executive director, and Justin Ward, Toyota's advanced powertrain program manager. Both offered predictions of the next 20 years of automotive powertrain segmentation, and both showed the internal combustion engine continuing to dominate, but its share gradually diminishing as gas/electric hybrids (HEV) and range extender (EREV), battery (BEV) and fuel cell FCEVs slowly grow.

Nitz pointed out that the last 37 years have seen vehicle fuel efficiency improve 180 percent for cars and 90 percent for trucks. He said that while the cost of EV batteries will come down and their energy density will increase over time, they will still carry only a tiny fraction of the energy of a tank of liquid fuel of equivalent size and weight. Ward talked at length about Toyota's soon-to-come plug-in hybrid Prius (above), which (because, like the Chevrolet Volt, it will operate for some miles on electric energy alone) will deliver better overall fuel economy than today's Prius.
