Much like the Mirai’s performance, there isn’t anything too far out of the ordinary to report here. Anyone with experience of Toyota’s hybrid line-up will recognise the chassis dynamic on show here: a competent (if not precisely classy) mix of ease of use and quietly respectable comfort.

For the most part, the car hides its not inconsiderable weight behind relatively quick steering and the sympathetic buoyancy of its lengthy suspension travel.

Stability control was a particular and recurrent problem, leading to panic stations and slowing the car unnecessarily

It is the sort of roving body motion that can become conspicuously choppy on fast British B-roads but which otherwise serves as a respectably pliant platform for most journeys.

An occasionally bony secondary response is reminiscent of the way the Prius family used to ride and indicative of the fact that the Mirai’s architecture is less up to date than the fuel cell at its heart.

The brakes aren’t perfect, either, suffering from a brittle, regenerative numbness at the top of the pedal that turns into oversensitivity the moment you push through it.

Nevertheless, the car makes for a benign presence – as long as you keep your expectations modest.

Exploit all of the Mirai’s performance on a road less than arrow-straight and, at best, it will lean slovenly away from the nearest apex; at worst, you’ll overcome what little grip there is and activate the primitive stability control.

Still, that there are far better-handling EVs on sale is hardly the point; as an initial proof of concept, the Toyota works just fine.

The Mirai brings the 2011 Nissan Leaf into mind with the loping softness of its suspension tune. But while that set-up makes the car entirely fit for purpose and a particularly comfy ride at town speeds, it also makes it intolerant of higher speeds through twists and turns.

Grip levels are quite low and body control is rather slack, allowing a fairly sudden rate of roll and enough lean angle to pull the rug out from underneath the steered axle. The car is by no means irredeemably compromised; it just prefers being driven gently.

The underlying stability is fine, the car letting go at the front axle long before the rear one threatens to run out of purchase.

It is a shame that Toyota didn’t spend a little longer tuning the car’s electronic stability control, however. It intervenes harshly and quite unnecessarily at the merest hint of overspeed at the outside rear wheel, often slowing the car to a crawl right on the apex of a corner — or potentially in the middle of a roundabout taken in a hurry.
