Domet

Koji raspon ćete zapravo dobiti?

Službena brojka je laboratorijski rezultat pri umjerenoj temperaturi. Dvije stvari to narušavaju na stvarnom putovanju: održavana brzina i hladnoća.

Zašto brzina toliko košta

Pri urbanim brzinama većina vaše energije ide u ubrzanje mase, a regenerativno kočenje vraća dobar dio toga. Na autocesti gotovo ništa od toga ne čini — neprekidno pomičete zrak, a taj trošak raste s kvadratom vaše brzine dok snaga potrebna raste s kubom.

Praktična posljedica je da je razlika između 110 i 130 km/h mnogo veća nego što sugerira razlika u brzini od 18%. Na dugom putovanju, smanjenje brzine za 20 km/h često štedi stanku za punjenje, što štedi više vremena nego što košta.

Brzina i potrošnja

Zimska kazna

Dva učinka se kumuliraju. Kabina treba grijanje, a u automobilu s otpornim grijanjem to izravno crpi iz baterije za pogon. A sama baterija prihvaća i isporučuje energiju manje spremno kada je hladna, što također usporava brzo punjenje. Studije koje mjere učinke ambijentalne temperature na potrošnju kvantificiraju kombinirani rezultat [1].

Česta pitanja

Koliko dometa gubim zimi?
Dovoljno da promijeni plan putovanja. Mjerenja u studijama potvrđuju znatan učinak temperature [1]; veličina ovisi o automobilu, sustavu grijanja i o tome koliko je hladno.
Trebam li usporiti?
Na dugoj vožnji autocestom, često da. Vrijeme izgubljeno sporijom vožnjom često je manje od vremena ušteđenog izbjegavanjem zaustavljanja.
Je li krovni kovčeg bitan?
Uvelike. Povećava čeonu površinu i otpor zraka, a upravo to vas košta pri brzini.
Zašto je moja potrošnja lošija nego u recenzijama?
Recenzije se često mjere na mješovitim rutama u blagoj vremenskoj situaciji. Trajna brzina autocestom i hladnoća dvije su varijable koje razdvajaju brojku iz recenzije od vaše.
