By distributing up to 10 miles of scope, in our testing, they demonstrated their worth.


  • The Tesla Model 3 comes standard with aero covers which protect nearly all of its 18-inch wheels. We wondered?
  • So we moved to the Chrysler Proving Grounds’ five-mile oval track to check that the Model 3 back to back with and with no covers.
  • They enhanced the Model 3’s efficacy by more than anticipated, an average of 3.4 percent over speeds of 50, 70, and 90 mph and an increase in range of up to 10 miles.

But by how much?


The aero wheel covers are exceptionally lighter they are, instead of if the wheel was created to look like this, with only five little openings between spokes. Tesla produced our test relatively simple because it sells a $50 accessory bundle of center caps and lug-nut covers to allow owners to expose that the arguably substantially better-looking multi-spoke aluminum wheels beneath the inventory covers.


Recently we took our long term Model 3 Long Range Double Motor into the Chrysler Proving Grounds’ five-mile oval track to place the aero wheel covers to the test. We ran the test under controlled conditions: the ambient temperature was a constant 44 degrees Fahrenheit, tires were set per the door placard specification of 42 psi, HVAC controls were set to 72 degrees on auto (this is done for all our street fuel-economy evaluations as well), and, most important, there was zero traffic and no altitude to skew the data. Tests were conducted back to back, and for each we did two loops of this five-mile oval. We then repeated each test a second time to guarantee accuracy.



Starting at a constant GPS-indicated 50 mph, we measured 258 Wh/mile with the aero covers off, and 250 Wh/mile together fitted. That’s an impressive 3.1 percent reduction in consumption and suggests a boost in complete range from 312 kilometers to 322. The outcomes were similar, with a consumption with all the aero covers of 318 Wh/mile falling to 310. That computes to a decrease of 2.5 percent and a boost in range from 253 kilometers to 260. Not surprisingly, we saw the best difference where the aero covers chopped through the atmosphere to the song of 405 Wh/mile in comparison to 424 Wh/mile’s number. That is a 4.5 percent decrease in consumption for the coated wheels, leading to calculated ranges of 190 and 199 mph, respectively.


Although it may not seem like much, the aero wheel covers was 3.4 percent more efficient across all three test speeds, which can be a sizable gain from the automotive world. That is about as much gain as much more than adding an engine stop/start system, and much switching into low-rolling-resistance tires or a transmission. The aero wheel covers improve efficiency and range from enough that owners should think twice before ditching them although remarks may vary on their looks.
