If you think a magazine devoted entirely to environmentally-friendly transportation can appeal only to preachy tree-huggers and alarmist ozone scientists, then you haven't seen Ron Cogan's "Green Car Journal." A longtime auto journalist and enthusiast, Cogan has infused this slick quarterly magazine with enough excitement and driving fun to rival any of the mainstream buff books. The only difference here is that everything's flavored with a green twist. Driving impressions, tech articles and well-balanced editorials share space with a thorough look at what's coming over the environmental horizon. Automotive times are changing and "Green Car Journal" is now a Must Read for anyone who holds a driver's license.
