Силовой баланс автомобиля
Проводим расчёт по равенствам:
Эффективной мощности двигателя и мощности на колёсах:
N
= 
, кВт; Ne1,1= 
кВт;
N
=
, кВт; Nk1,1=
кВт;
Мощности внешних сопротивлений:
N
= 
, кВт; Nf,1 = 
= 0,501 кВт;
N
=
, кВт; Nw,1= 
= 0,015 кВт;
N
= N + N , кВт; Nc,1= 0,501 + 0,015=0,516 кВт
