The Lexus RZ 450e, which is one of the latest all-electric models in the United States market, was recently listed on Environmental Protection Agency (EPA)'s website.
The previously announced EPA Combined range numbers of the two RZ 450e versions - one with 18-inch and one with 20-inch wheels - were officially reiterated at respectively 220 miles and 196 miles.
* a larger wheel diameter usually results in higher energy consumption and a lower driving range (assuming the same tire.
However, when we further research the EPA documents, it turned out that the version with 20-inch wheels might be above 200 miles, as there is a special annotation - "Combined range voluntarily lowered from 202 miles." That's six miles (or three percent) more than the EPA Combined rating.
- 18-inch wheels: 220 miles
- 20-inch wheels: 196 miles
(voluntarily lowered from 202 miles)
The difference is not very high, of course, and would hardly be noticeable in the real world because various other factors can affect the driving range very substantially, but it seems that the Lexus RZ 450e might be a 200+ mile BEV in all versions, even the one with bigger wheels.
Manufacturers sometimes voluntarily lower their EPA Combined range, but it happens rarely (a few percent of all models/versions). We assume that some of them are playing conservatively, while others might not be sure of the final numbers.
If we compare the first all-electric Lexus with its direct cousins - the Toyota bZ4X (AWD version) and Subaru Solterra (AWD), it turns out that Lexus' EPA Combined range is slightly lower, but at the same time, we must note that it has a bit smaller battery - 71.4-kilowatt-hour (kWh) from Prime Planet Energy Solutions (Panasonic and Toyota's joint venture), rather than 72.8-kWh from CATL.
The Lexus RZ 450e is slightly more efficient than the AWD version of the other two cars and has more power (150-kilowatt front motor and 80-kW rear motor instead of two 80-kW motors). On top of that, the Lexus RZ 450e's battery can fast charge at up to 150 kW according to the specs, compared to 100 kW in the case of CATL battery, which is used in Toyota bZ4X AWD and Subaru Solterra.
Energy consumption, including charging losses, of the Lexus RZ 450e is estimated at:
- 18-inch wheels: 107 MPGe: 315 Wh/mi (196 Wh/km)
- 20-inch wheels: 95 MPGe: 355 Wh/mi (220 Wh/km)
EPA listed also Lexus RZ 450e's City and Highway range ratings. In the city, the range is expected to be slightly higher, while on the highway slightly lower. In the case of the 20-inch version, the EPA Highway number is less than 178 miles, which might be not enough for many customers.
