Would You Trade Performance For Fuel Economy?S

We've been harping on about gas prices lately because it is clearly impacting the market. In fact, we wonder if this guy didn't drive his Suburban onto a firing range just to collect the insurance and buy a hybrid (only to find out he can't). Many vehicles come with a choice of engines, offering various levels of power and economy. Would you choose the slower car for better fuel economy? Have you?

Personally, we like what Ford is doing with EcoBoost by combining turbocharging and direct-injection to get more power out of smaller engines. While we wait for those cars to start arriving at dealerships, it's worth asking if every vehicle in the garage needs to be the fastest. We're not saying trade down to a fuel-efficient beater, but maybe four cylinders instead of six? Or is that blasphemy?
