Lexus UX 300e - range test. 205 km at 90 km/h, 166 km at 120 km/h, possibly LFP cells [video]

Bjorn Nyland tested the real range of the Lexus UX 300e. And that seems to have cleared up why Lexus might offer users a 10-year warranty on car batteries. This 54,3 kWh C-SUV crossover weighs as much as the 3 kWh Tesla Model 74 LR RWD and more than the 64 kWh Kia e-Niro. This suggests that it uses lithium iron phosphate (LFP) cells.

LFP cells degrade more slowly than cobalt cells (withstand several thousand cycles of operation), but have a lower energy density, so more of them are required to achieve the same capacity. Lexus UX 300e Weight – measured with driver and equipment – ​​equal to 1,88 tons indicates that the battery must be very heavy. But for LFP cells, air cooling is clearly sufficient.

The car meters have been adapted from the car combustion variant: The battery level indicator used to be a fuel gauge.at the same time, the coolant temperature gauge was simply cut out. To maintain a real 90 km / h, Neeland had to accelerate to 97 km / h.which explains why Lexus and Toyota drivers regularly brag about their hybrids' excellent fuel economy figures - they just drive slower than they think.

There was more surprise: with fast charging (Chademo), the car was recharged with energy up to 95 percentit had to be connected to the AC charging pole to bring it up to 100 percent. On the charger, the car reached 43-44 kW, while other car users reported a maximum of 33-35 kW. Finally, on the UX 300e at 120 km / h the cabin was louder than a Tesla Model 3.

range at a speed of 90 km / h was 205 km, the energy consumption has reached 20,1 kWh / 100 km and it seems that the manufacturer allowed only 41,2 kWh of batteries (!). At a speed of 120 km / h Lexus UX 300 e already used up 44,7 kWh of batteries and reached its maximum 166 kilometers range... Hence we conclude that The manufacturer's stated 300 kWh UX 54,3e battery is a generic figure..

Lexus is promising 300 WLTP units in the UX 305e lineup. The car is a direct competitor to the Kia e-Niro, at least on paper.
