You can do things to a Prius to get that kind of mileage. There are aftermarket battery kits that give you plug-in capability, for instance, but they’re expensive, and the auxiliary battery can’t be recharged from the primary system.
As to “hypermiling,” all of the following apply:
- If you drive 35 MPH on the Interstate, you’re an asshole, and you’re probably breaking the law.
– Trucksucking is stupid and dangerous.
– Overinflating your tires is stupid and dangerous.
BUT:
- Shutting the engine off when you have to sit for a couple of minutes is a good idea
– Shift into neutral or park at stoplights. Better yet, ditch your automatic transmission and drive a stick. Automatics are the biggest gas-wasters ever invented, not to mention that they sap power.
– Keep your tires properly inflated.
– Get rid of that junk in your trunk
– Don’t use premium gas in an engine that doesn’t require it. Like burning money.
