Hyundai introduced its all-electric 2023 Ioniq 6 SE RWD Long Range trim achieved an EPA-estimated vary of 361 miles on a full cost.
The EPA figures work out to 140 mixed MPGe for the mannequin. That ranking equals the effectivity of two Lucid Air fashions which are on the high of Fueleconomy.gov’s 2023 Top Ten Vehicles listing.
The dual-motor Ioniq 6 SE AWD Long Range was rated at 316 miles in the identical check. The SEL and Limited trims each ranged 305 miles with RWD and 270 miles of their AWD configurations.
“Continually improving the efficiency of our vehicles is always a top priority for our development teams,” mentioned Olabisi Boyle, vice chairman, product planning and mobility technique, Hyundai Motor North America.
“Instead of just adding a larger battery to increase the range, we chose to optimize Ioniq 6’s aerodynamic performance and its Electric-Global Modular Platform for efficiency to produce these long driving ranges.”
Ultra-aerodynamic design
One motive for the rise in effectivity is the Ioniq 6’s ultra-low drag coefficient of 0.22. The general aerodynamic design of the car is assisted by a low nostril, energetic air flaps, wheel hole reducers, an elliptical wing-inspired spoiler with winglet, slight boattail construction, separation traps on each side of the rear bumper, full underbody cowl, deflectors and decreased wheel-arch gaps. All of those options work collectively to permit the Ioniq to slide via the air extra simply than most autos.
The actual information with the Ioniq 6 vary ranking is that these figures had been achieved with a standard-range battery of 53 kWh capability, and a long-range battery of 77.4 kWh. That yields a miles-per-kWh determine of 4.66 for the long-range and 5.75 for the usual vary batteries. The customary vary affords a greater miles-per-kWh determine due to the lighter weight of batteries within the car.
Efficiency shouldn’t be the enemy of efficiency, both. The Ioniq 6 in rear-drive configuration affords 149 horsepower, whereas the long-range motors supply 225 horsepower in rear-drive single motor configuration and 320 horsepower with the dual-motor setup. The dual-motor lengthy vary configuration is able to 0-60 acceleration in beneath 5 seconds, so patrons are usually not giving up a lot energy for the rise in effectivity.
Comparative effectivity
The comparability in MPGe with the Lucid Air is about general effectivity. With batteries sized at 112 to 118 kWh of capability, the Lucid merchandise supply as a lot as 4.62 miles-per-kWh. The Tesla Model 3 offers as a lot as 4.17 miles-per-kWh, for comparability.
Less aerodynamic or weight-efficient autos have a tendency to supply about 3.3 to three.6 miles-per-kWh, and these are nonetheless probably the most environment friendly EVs available on the market immediately, after the Ioniq 6 and Lucid Air. Vehicles on this vary embrace the Chevrolet Bolt and Bolt EUV, Hyundai Kona and Ioniq 5, Tesla Models S and Y, and the Kia EV6 and Niro EV.
As EVs make up a higher share of recent automobiles offered, these measurements of effectivity will turn into extra generally understood and valued. The legal guidelines of physics haven’t modified, so weight and aerodynamics will proceed to play a serious function in any car’s power effectivity.
