Back in 1965, diesels weren't the torquey mpg champions we have today. They were weak, noisy, and smokey. Still, I would take this Peugeot for a ride any day.The French simply wanted to beat world records for diesels, so they built a lightened and streamlined 404 prototype and took it to the Montlhery Autodrome. You know, the place near Paris where Ken Block drifted up a wall. In June, powered by a 2163 cc engine, the car completed a 5,000 km (3,106 miles) run at an average of 99 mph.
