60 mpg how bout 100mpg

For some young men, the trunk is the perfect spot for a huge set of car speakers. (Berwyn?)
But brothers Andrew and Chris Ewert have put something far more powerful in the back of their parents' Toyota Prius: a lithium-ion battery pack capable of dramatically boosting the hybrid car's already impressive fuel efficiency.
Unlike a conventional gas-electric Toyota Prius, which gets about 55 to 60 miles per gallon of gas, the Ewerts' so-called "plug-in hybrid" is capable of traveling about 100 miles per gallon.
And it only takes 35 cents' worth of electricity from a standard power outlet to charge the extra batteries.
"We've gotten about a thousand miles off of one tank of gas," Andrew Ewert said. "This is the future of cars. We strongly believe that this is where it's headed."
The Ewerts' modified car was among dozens of alternative fuel vehicles on display Tuesday at an Earth Day event at Wheaton College.
U.S. Rep. Peter Roskam kicked off the event by saying America must end its dependence on foreign oil.
In the 1950s, the U.S. imported about 3 percent of its energy needs. Roskam said the nation now is importing almost 22 percent of its crude oil from other nations.
"Obviously, in an increasingly unstable world, that tends to make us more vulnerable," he said.
Among the energy-efficient vehicles on display during Tuesday's exposition was a battery-powered scooter and a Honda Civic powered by natural gas.
