2015 Acura TLX SH-AWD: A V6 With Brawn and Brains
April 17, 2015
Opting for the 3.5-liter in the 2015 Acura TLX not only puts 290 horsepower under the hood, it also gives you the chance to get more than 30 mpg on the highway. At least, that's what the EPA says.
Since we're barely past the break in miles, our TLX hasn't had a chance to show what it can do in the efficiency department, but it has all the tools. Matt Jones has already talked about the start/stop system which is a slightly controversial feature. On the flip side, this V6 also has Acura's Variable Cylinder Management (VCM) system, which can shut down half the cylinders under light load.
Unlike the more obtrusive start/stop system, VCM is virtually undetectable. I didn’t even realize this engine had VCM until I read the spec sheet. The technology behind it is quite complex, but its implementation is flawless.
Until I have the chance to stretch this car out on a long highway drive, I'll reserve judgment on its efficiency in the real world. So far it's delivering somewhere in the low 20s in combined driving, but expect that number to increase in the next few months.
