Noiden kokonaispaino yhdessä tankkien kanssa ei ole lähellekkään 480kg mikä Teslan akuston paino. Lisäksi Tesla EPA arvo on kaukana todellisuudesta, Toytotasta en tiedä.
Mitä sitten, jos henkilöauto kokonaisuutena painaa vähemmän? Käsittääkseni EPA -testit ovat molemmille autoille samat ja siten vertailtavissa. Molemmat luvut ovat todennäköisesti ylioptimistisia (kuten myös WLTP), mutta vertailu reaalimaailmassa on hankalaa monista muuttujista johtuen. Molemmilla voi varmasti ajaa taloudellisesti tai tuhlailevasti. Pari anekdoottia Miraista, Model 3:sta on kokemuksia netti väärällään:
"
Toyota says that the Mirai consumes 0.89kg of hydrogen every 62 miles; in the UK, a refill costs about £10 per kg. Our test drive covered more enthusiastic driving than most will subject it to, and the Mirai consumed 1.17kg per 62 miles -
equating to about £56 for a 300-mile real world range. That’s a similar cost to a petrol car achieving 32mpg."

"When I hopped into the Mirai to start the day, it had a full tank of hydrogen but a
trip computer estimated range of just 234 miles, well off the Limited’s estimated range. Toyota says that this is because the trip computer takes time to learn the driver’s style of driving to offer an accurate range estimates and the test cars had been mostly driven by journalists who like to drive more enthusiastically, shall we say.
Up until a fill-up that took place about two-thirds of the way through the drive route, I covered 63.5 miles and the range remaining according to the computer fell by 69 miles to 165 miles remaining. I was driving vigorously on a winding road (fulfilling stereotypes) for a decent portion of those miles and the trip computer also reported that
I averaged 43 mpge over that time, far less than the Limited’s estimated 65 mpge combined rating."
The 2021 Mirai moves to a rear-wheel drive platform borrowed from Lexus and gets improvements to the fuel cell stack, the interior, and the tech throughout.

"
Consumption is officially rated at 0.7kg of hydrogen per 100km. After a handful of different drivers on nothing but 50–70km/h stop-start streets, the Mirai
indicated a 0.88kg/100km figure, which is about
25 per cent over its claim – really no different to what we see in most petrol-powered cars against their claimed consumption. This makes it more efficient than Hyundai's Nexo, at least. "
Mutta eiköhän se ole ihan riittävä, kun tankkaus kestää vain pari minuuttia.
