A Quart of Small Block, Please
AP writers must have automated tools to supply equivalent units of measurement in articles destined for foreign readers. At least, that's my guess after reading this:
Rumbold also questioned whether a high performance car such as the LS Lexus 600h--with a powerful 1.3-gallon (5-liter) V-8 engine and a top speed of 155 mph (250 kph)--is actually the best use of promising hybrid technology.
So, what on earth is a "1.3-gallon" engine?
"Yes, I'm house shopping, and I won't settle for anything smaller than 100,000 gallons."
(Time was all us Yanks would have called it a 305-cubic-inch engine. That hasn't altogether disappeared, but these days it's more common just to hear liters.)
