Normally aspirated and turbocharged V-6 engines are the norm, which is why the 2012 Lincoln MKT isn't the most fuel-sipping crossover on the market.
However, the big, bold MKT is rated fairly highly, among vehicles with third-row seats. The EPA gives the MKT with the normally aspirated V-6 a rating of 17/23 mpg, when it's outfitted with front-wheel drive. With all-wheel drive factored in, the numbers fall to 16/22 mpg.
The EcoBoost MKT, with its turbocharger, drops another mile per gallon, checking in at 16/21 mpg.
Ford will not offer hybrid or diesel powerplants in the MKT. The big crossover is already one of the most expensive Lincolns, and adding on those high-tech fuel savers would send its sticker price soaring.
