The first Toyota powered exclusively by energy stored in an accumulator was an SUV, commercially called bZ4X. Already here We have looked at the explanation of the name, as well as the main characteristics of this model, the novelty now residing in the announcement of the autonomy and in the guarantee advanced by the Japanese brand for the battery. The bZ4X should be able to travel up to 511 km between recharges, a WLTP-certified range for the front-wheel drive version, and the accumulator is covered by a 10-year or 1 million kilometer warranty.

The Japanese manufacturer is thus following the strategy adopted by the luxury brand of the group, since the Lexus UX 300e also guarantees that after a decade, the battery will not see its capacity degrade below 70% or present defects. functional. Which means that, in the event that this happens, the customer can claim and is protected by the guarantee, simply by following the maintenance plan recommended by the manufacturer. Given what is usual in the market, we are considering an “extension” of the battery warranty, as most car manufacturers offer eight years or 160,000 kilometers – Tesla goes up to 192,000 km in the long-range Model 3 or 240,000 on the S and X. That means Toyota adds two years to the coverage or, in terms of mileage, quintuples the warranty (which should equate to about 2,500 full charge cycles).

The Toyota bZ4X, which will be presented and will open reservations on April 7, uses a specific platform to house the batteries, the eTNGA, assembling in particular an accumulator with a capacity of 71.4 kWh, cooled by liquid. The electrical system handles up to 150 kW on DC charging. The Japanese SUV will be introduced in Portugal in June, initially only in the front-wheel drive version, which has a 204 hp electric motor, like the Lexus UX 300e. In this case, to reach these 511 km of autonomy, the brand promises an average consumption of 14.3 kWh / 100 km. This is a respectable figure, if we consider for example that the Mercedes EQB, practically the same length as the Toyota bZ4X, announces an average consumption of 16.4 kWh/100 km in the less powerful 250 version (190 hp ). The 66.5 kWh battery (rechargeable up to 100 kW direct current) only allows you to homologate 470 km between visits to the charging station.

Later, Toyota is also expected to launch a version of the bZ4X with all-wheel drive, thanks to the use of two electric motors of 109 hp each (one on each axle). With a combined output of 218 hp, this AWD variant continues to use the same battery, so consumption increases (15.8 kWh/100 km) and range decreases (470 km).
