A bet: Toyota will beat GM to the plugin electric hybrid

Posted by: Adam Aston on July 26

The dissonance of GM's green messaging hit me again with Toyota's announcement that it is now formally testing PHEVs in the US, at UC Irvine and UC Berkeley. While Toyota has said it had been developing PHEVs for some while, the news moves its efforts into the daylight. Toyota's go-quietly strategy is consistent its recent habits. As the company gets closer to eclipsing GM as the world's No 1 vehicle maker, Toyota has become increasingly subdued in playing up its growth and technology plans.

Why NYC’s Yellow cabs took so long to go green

Posted by: Adam Aston on May 24

For the city, hybrid taxis mean cleaner urban air, less energy consumption, and lower costs. So why didn't the shift happen sooner? Consider the simple economic savings this move promises. The city estimates the plan will save 22 million gallons of gas -– and related emissions -– in the first year alone. For a hack driver making the switch from a 10-mpg Crown Victoria to a 30-mpg hybrid, daily savings in fuel costs could hit over $100 on a 12-hour shift, particularly with gas going for $3.50 or more at city stations. Those savings go straight into drivers’ pockets and lower the pressure to increase taxi fares down the road.
