Honda has a new gas/electric hybrid for 2005. A 6-cylinder Accord. This car comes with effeciency and power. It gets like 45 mpg and has something like 243 hp. Under most circumstances it uses all cylinders but the "brain" figures when to turn three of the cylinders off so that it's only running on half. You never feel the transition or notice a power loss. comes in real handy on the highway and such when you're cruising along.
