Peraves produced 90 Ecomobiles from 1991 to 2005 until the main factory in the
Czech Republic burned down. In response, Peraves decided to commit to redesigning the Ecomobile. The new, more affordable design was named the
MonoTracer. It was named number 41 in
Time's list of the 50 best inventions of 2008. The electric version was named
E-Tracer. In 2010, Peraves won the $2.5 million
Progressive Insurance Automotive X-Prize with a prototype version of the electric MonoTracer/E-Tracer, renamed the
X-Tracer, capable of driving up to and accelerating from in under four seconds. The design was originally suggested by Stefano Paris, an aero-mechanical engineer who saw the gas version on display. In 2013, the X-Tracer was blocked from entering the United States while at the
Port of Los Angeles by the
EPA, United States Customs, and the Transportation Department because the vehicle didn't comply with government regulations. Electric vehicle advocate Paul Scott commented, "For the EPA to be in the way of this is as bizarre at it gets." ==References==
