Gas Mileage for a 1994 Infinity Q45

by Richard Rowe

Nissan has always understood the power of branding, and that hasn't always worked in its favor. When it originally entered the United States economy-car market, Nissan slapped the slightly more disposable "Datsun" name on its products. After Datsun went huge with the Z-Car, Nissan began using its own name again. But when it wanted to go upmarket, Nissan took the unconventional-for-the-time approach of creating a whole new division out of nothing to sell more luxurious versions of its mainstream cars to U.S. buyers.

In modern parlance, the "Q-Ship" is another name for a "sleeper" -- a car that doesn't look anywhere near as fast as it is. That nickname, which originally described decoy ships used in WWII, was said to have been the inspiration for the Q45's name. While very restrained in appearance, Nissan's Q-Ship offered some truly impressive acceleration -- 6.7 seconds to 60 mph -- and handling, for a Japanese car in its price range. With a 4.5-liter V-8 making 276 horsepower, the Q45 was absolutely on par with its upmarket competition from Germany; but at 3,900 pounds, the Q45 was never destined to be a gas saver. Infiniti rated base models at 17 city and 22 highway, and sport models at 15 city and 21 highway. Owners typically see 14 city and 20 highway, or an average of 16 to 17 mpg.
