Hemmings Motor News Blog Blog

Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

And That’s the Truth: Frank Gripp’s Twin-Engine Diamond T

Lloyd J. Wolf might have been peddling his auxiliary power units for over-the-road trucks by then, but in the mid-1960s not everybody felt it necessary to purchase a Dynassist to increase their load-carrying potential, as we can see from this one-off 1957 Diamond T 730C cabover featuring an unconventional power-adder and some owner-executed rhinoplasty.

The Geppetto to this Pinocchio, Frank Gripp Sr., ran Gripp Trucking out of Annawan, Illinois, from the 1940s through the 1990s, specializing in grain hauling among the rural communities that dotted Route 6 - and later, Interstate 80 - in the northwestern part of the state. By the mid-1960s, he'd hired his son, Frank Gripp Jr., as a driver, and the younger noted how the 450-cu.in. International Harvester Red Diamond six-cylinder gas engine in the tag-axle cabover couldn't quite keep up with traffic.

In modern buses and trucks can we use this method to run single engine when load is less & both engines when load high?.

Citroen had a twin engine 4x4 car from 1960 to 1966. The small 2 cylinder engines were not powerful enough for a 4x4, so a second engine was installed. It was a 2CV.
