Range, charging & running costs Rating

4.0 out of 5

There are two versions of the Toyota bZ4X and both use the same 71.4kWh battery. These are the front-wheel-drive (FWD) and all-wheel-drive (AWD) models, and they have different amounts of power and range because of the different drive layout. 

The FWD model has 201bhp and the AWD version has 215bhp. In both versions, the batteries are incorporated into the car’s body, under the floor. This helps to keep the car’s centre of gravity low – this helps with handling, and you can find out more about that in the relevant section of our review.

Toyota bZ4X range & charging

Since the bZ4X has the same battery no matter which version you go for, the differences in range are down to the extra electric motors on AWD versions. The FWD model has an impressive range of 321 miles, while the AWD model has 286 miles - both of these are the official stated figures, so treat them as a maximum.

In our initial drive of the bZ4X (in top-spec AWD form) we saw efficiency of 3.4miles/kWh, which would result in a range of 240 miles. That’s not too far off the claimed figure for a top-spec car, so the bZ4X is relatively efficient.

Charging is identical no matter which version you choose, since the battery and charging tech is the same in both models. From a home wallbox charger it takes 12 hours and 45 minutes to charge (at 7.4kW) although if your home supports 11kW charging that drops to seven hours and 45 minutes. To get this time you’ll need to wait for a later bZ4X model, because early cars won’t be able to make use of 11kW charging. 

At a public rapid charger the bZ4X charges from 10-80 per cent in 70 minutes at 50kW or just 32 minutes at a 150kW-capable charge point. That’s not quite as fast as a Hyundai Ioniq 5, but it’s competitive enough.

Insurance groups

The FWD model with 201bhp sits in insurance groups 37 or 38 depending on trim level. This is quite high, but this is probably because the car is quite powerful. The AWD version is in insurance group 40 (out of 50) no matter which trim level you choose – even the top-spec version sits in this group.

Warranty

All Toyotas come with one of the best warranties in the new car world. As long as you have the car serviced at an approved garage, the warranty runs for up to 10 years or 100,000 miles. This is even better than the seven-year cover you get on a Kia EV6.

Servicing

If you pay for a bZ4X through Toyota’s latest leasing scheme then servicing is free for the first three years. Otherwise, it’s £180 for a small service and £260 for a major service, which seems reasonable.
