At the last Paris Motorshow in 2008, Renault displayed this big chronological timetable to show all their technological breakthroughs to make cars more environmentally friendly.
But, it would have been better if they had released a hybrid car like Prius...before Toyota did. Then stars would have ridden in Renault car, making it hype, cool, and clean. Would get great press. All this free of sponsoring. Toyota is playing in another level than Renault - although both are still in Formula One ;)
