Watch: 2014 Ram 1500 EcoDiesel video walkaround

Mike Cairns, chief engineer for Ram, says that people just can't help but pester him with the same damned question: “Why don't you put a diesel engine in a 1500?” Thanksgivings were, we imagine, brutal.

Four million drivers aged over 70

THE NUMBER of people aged over 70 who hold driving licences has exceeded four million for the first time, according to the RAC Foundation. The oldest licence holder is a 107-year-old woman, while there are 191 people aged over 100 who have licences. Once people reach 70 they must declare whether or not they are fit to drive every three years, without having to take a driving or medical examination.

But unlike us, coachbuilder Rinspeed is actually taking the yet-to-materialize issue seriously, and at the upcoming Geneva Auto Show it will debut its XchangE concept.
