The Mercedes EQS is the existing flagship electric car from the Stuttgart-based high-end automobile maker. It includes among the longest driving ranges of any electric automobile on sale today. Available in 3 versions currently– EQS 350, EQS 450 and EQS 580 4MATIC– it is the mid 450 which provides the greatest range in the household.
For the purpose of iterating the effect of wheel style and size on the variety, we are focusing just on the Mercedes EQS 450 ‘s WLTP combined variety figure.
To begin with, the EQS 450 can be defined in the Edition 1 configuration, however if you are after maximum range, you must avoid this version which gets 21- inch wheels as requirement. Next up, on the exterior bundle, the EQS 450 can be spec’ ed in Standard, Electric Art, AMG Line and an optional Night Package (which adds personal privacy glass).
If you are after optimal range from your Mercedes EQS, choose the AMG Line, which will give you 19- inch AMG 5-twin spoke or 20- inch AMG 5-spoke alloy wheels as basic fitment. Selecting the 19- inch AMG wheels will see the Mercedes EQS declare a 759 km range, whereas the 20- inch wheels drop it down to 746 km. The optional 21- inch wheels, which need an extra 1,500 EUR, drop the range further to 732 km.
Interestingly, the non-AMG line wheels also see a drop in variety on the EQS. The 19- inch 10- spoke style offers 745 km, whereas the 20- inch 5-spoke see the range dip to 727 km, regardless of being a 1,500 EUR choice on the basic line. The least effective wheels need to be the 22- inch 5-twin spoke systems which cost 3,500 EUR however offer only a declared 683 km of variety which is a considerable 76 km drop over the 19- inch AMG wheels, or a 10 percent lowered driving variety.
Aerodynamics play an important function in the effectiveness of an electric cars and truck, and the Mercedes EQS is no different. With bigger wheels, not just does the weight of the rim somewhat increase and the aerodynamic drag boosts, but the size of the tire progressively increases too, which leads to increased contact with the road surface, increasing friction. The 19- inch AMG rims sport 235 section tires, whereas the 20- inch wheels need 255 area, which further increases to 265 on the 21- and 22- inch wheels.
Ultimately, electrical cars mirror their gasoline siblings here. The effect of wheels is far more pronounced on the previous. For contrast purposes, a Mercedes S500 4MATIC’s fuel performance only takes a 4.5 percent hit when selecting the large 21- inch rims against the smaller sized 18- inch units.
