Drivers care about miles per dollar, not miles per gallon.

摘要

According to the Univ. of Michigan Transportation Research Institute, new cars sold in the US in Nov. averaged 25 mpg (10.63 km/1), down 0.1 mpg (0.04 km/1) from the month before and 0.8 mpg (0.34 km/1) from the high reached in Aug. 2014. The figure was still 4.9 mpg (2.1 km/1) above Oct. 2007, however, when Univ. of Michigan researchers first began tracking the data. The reduction is said to be due to increased purchases of larger, more powerful vehicles as fuel prices weigh less heavily on motorists pocket-books these days. According to Ford Motor Co., US drivers are set to buy a record-breaking 5MM sport-utility vehicles in 2015, pushing SUV's US market share to 40%.
