Thus far, the North American International Auto Show has been a truck festival – more specifically, a green-truck fest. Ram showed a hybrid 1500. Ford revealed their V6 diesel. Chevrolet surprised with an inline-six diesel. Clearly the Big Three are looking at the calendar, with a big red circle over the 2025 CAFE standards looming like a dark cloud.
Achates Power, a fourteen-year-old startup from San Diego, has a different idea. By combining a variety of existing technologies – some of which date from before World War Two – they have developed an engine that they expect to meet 2025 fuel economy standards, emissions standards, and most importantly, the performance standards of light-truck buyers.
How does 37 mpg sound in a half-ton truck? That’s on gasoline. The Achates engine can also manage 42 mpg in the same truck running on diesel.
