For its performance levels, the mid-level version of the 2012 Mercedes-Benz SLK delivers good fuel economy. A coming four-cylinder model promises even better numbers, though the monster V-8 edition likely will be significantly lower.
Sportscars don't often nudge 30 mpg in highway gas mileage, but the new SLK does. The SLK 350 earns an EPA-rated 20/29 mpg, thanks to its small size and its standard seven-speed automatic.
Grab the reins on the SLK55, though, and the numbers should drop back to earth--the EPA hasn't rated it, but Mercedes suggests a highway figure of 26 mpg. The V-8 incorporates cylinder-deactivation technology that shuts off fuel to four of the eight cylinders under light running loads.
The V-8's gas mileage could be offset by the upcoming four-cylinder turbocharged SLK, which likely will top 30 mpg on the highway.
Conclusion
For a sportscar, the SLK 350's highway gas mileage is very good--but it won't be the only SLK for long.
