The individual car has been sold to society as an engineering expression of freedom, as told by various stories such as the dust bowl migration. Grapes of Wrath No irresponsible road racers Cannonball run. And decades of reliance on fast-moving liquid hydrocarbons for fuel, waiting for lithium-ion cells to recharge, has left little tolerance for many minutes more plug-in and static spending. So when it comes to bench-racing electric vehicles, the only thing most people care about is how far it goes before you need to plug in again.
The situation is not exactly helped by the tests used by regulators. In Europe, the WLTP test cycle averages 29 mph (47 km / h) and produces series estimates that should be considered as mere fantasies on North American roads. U.S. The Environmental Protection Agency’s test is twice as average, but then some are subjected to a hefty penalty while flattering others. Therefore, it is interesting to see the results of independent series tests of some EVs in which they are charged then run them at a steady 70 MPF (112 km / h) until they stop.
The study was started by Polystar, which wanted to put its new Polystar 2 EV in front of three competitors: Tesla Model 3 Performance, Jaguar i-Pace and Udi D e-Tron. The test, conducted over a three-mile (8.8 km) ellipse on July 28 at Mount Michigan’s Fowerville Providence Ground, was straightforward.
Each car was brought to a state of 100 percent of charge and set to its default default drive mode with regenerated braking off (or in its most humble setting). The indoor temperature was set to 72˚F (22˚C), the tires were inflated to the pressure indicated on the placard of each car door, and the headlights were turned on (test track required).
Trains were then driven slowly from the staging and charging area to the staging and charging area (less than 25 MPa for 25 MPa to 1.3 miles / 40 km / 2 km), then everyone was slowly accelerated (at 0.3 G). A GPS-verified at 70 mph, and was kept there with the cruise. Control, all running from a distance in the same lane on the test track. Each car was driven until it could maintain a top speed of 70mph due to the depletion of the depot.
Shows Tesla’s experience
It should come as no surprise that Tesla’s Model Dell 3 traveled the longest distance, reaching 234 miles (377 km) -75 percent of its EPA range – before dropping below 70 mph. Tesla has spent more than a decade continuously improving the range efficiency of its electric powertrains and has applauded its vehicles in low-pull bodies, and a wealth of experience has shown on the test track, even with 20-inch wheels and high-performance tires. .
The Polstar 2 was a runner, traveling 205 miles (330 km) before reaching 70mph. The Polystar is still waiting for the official EPA range estimate for the Polystar 2, but if it comes to the expected 250 miles (402 km), it will be 82 percent of the car’s official range.
In fact, the company provided a pair of Polystar 2s for testing, one of which is equipped with 20-inch larger wheels and sticky summer tires from the display package (which we tested a few weeks ago). Larger wheels and sticky tires are the last thing on a car when it comes to more miles per electron, and that’s eight miles (13 km) or about three percent less than the fine. Similar cars on 19-inch wheels and low-rolling resistance rubber.
Next was the i-Pace, an EV400 HSE trim with 22-inch wheels. The British battery EV completed 188 miles (302 km) before Kaka cried, 80 percent of its 234 mile (377 km) EPA-rated range. (Jaguar recently sent out a software update for i-Pace that increased the range’s efficiency to 12 miles (19 km), but that didn’t affect BEV’s official EPA range.)
Last place was the Udi de E-Tron, which drove 187 miles (300 km) a day before saying goodbye. However, the bright side for Udi D’s engineers is that the E-Tron travels 92 percent of the officially rated 204 miles (328 km), making it closer to its EPA range than any other. A D was also the first to arrive at the full stop. Every other car gladly traveled a few more miles to get out of the oval and back on the plug, despite the 0 miles indicated on the dash; The E-Tron stops after 1.9 miles (3 km).
The case goes on, even if you urgently need an electric car to get from coast to coast, you can’t beat Tesla.
