Toroidal LPG tanks improve space utilization

Passenger cars fueled by propane autogas are a common sight on European roads today, and many of them use toroidal fuel tanks. The toroidal tank is aptly named because it resembles the circular geometric object called the torus. It’s a great space-saving solution because it fits within the car’s spare-tire space, leaving the whole trunk area available.

While toroidal tanks have been popular in European vehicles for 20 years, they were only first introduced in the United States about a year ago, towards the end of 2014. Compared to Europe, the U.S. is a different market, focused on the conversion of new or existing fleet vehicles by propane autogas system integrators. Nevertheless, interest in toroidal tanks is strong and growing among U.S. integrators, for the same reasons they are by European vehicle OEMs – a flexible design option thanks to the unique tank shape, along with reliable performance and value over thousands of miles of driving.
