GM Defends the Volt’s Design
A recent Carnegie Mellon University study (pdf) challenged the real-world gasoline savings and cost effectiveness of plug-in hybrids like the Chevy Volt. GM’s Vice President Global Program Management, Jon Lauckner, who has been involved in the Volt project responded on the company’s blog. Find out what he had to say below.

All-Electric Range

The first thing is the electric range of the car. Somewhat strangely, the CMU study found that “for urban driving conditions and frequent charges every 10 miles or less, a low-capacity PHEV sized with an AER (range) of about 7 miles would be a robust choice for minimizing gasoline consumption, cost and greenhouse gas emissions.”

7 miles? Really?

Well, Jon Lauckner responds:

I’ll cut to the chase; for starters, the study’s endorsement of plug-in vehicles with only a “token” electric-only range (seven miles) overlooks the inconvenience of recharging for the vast majority of drivers (approx. 90 percent) with a daily commute that exceeds seven miles. I mean, honestly, how many customers are going to stop every seven miles and wait at least 30 minutes (if a car has a high-capacity charger like the Volt with the same level of electrical energy to match it) for their battery to be recharged? […] And, if customers don’t recharge during the day, these “token” plug-ins will run primarily on gasoline. How is that consistent with reducing green house gas emissions and our dependence on petroleum?

Amid a wave of government-led bailouts for car companies, a group of international agencies and motoring organizations called on Wednesday for car makers worldwide to reduce emissions.

“In confronting the economic recession this is a real opportunity for governments to combine support for the auto industry with measures to achieve environmental and energy policy goals,” said Nobua Tanaka, the executive director of the International Energy Agency.

“Battery electric vehicles, plug-in hybrids and possibly hydrogen fuel cell vehicles are expected to become increasingly available in the near-to-medium term given recent improvements especially in batteries,” the 50-by-50 campaign noted in a leaflet. “However, these advanced technologies are not necessary to achieve the 50 percent potential described here, but could result in further CO2 reductions and oil savings if they succeed in achieving mass-market commercialization.”
