Two Ford F-150s were purchased for our test fleet, one with the familiar 3.5-liter EcoBoost V6 and the other with Ford's new 2.7-liter EcoBoost V6. Acceleration results from our test track proved surprising. Less surprising were the fuel economy numbers from the lightweight aluminium-bodied truck; we put those into perspective. In other news, our Tesla Model S P85D suffers an early malfunction, highlighting Tesla's customer service. We then reach deep into the mailbag, answering a variety of inquiries.
