Friction - reducing design features, including all - new ultra-low viscosity transmission fluid, internal thermal bypass,
minimal number of non-applied clutches and other lower mechanical spin
losses, contribute to the 10 - speed's effect on improved vehicle
efficiency.
Compare that with (say) a combined - cycle gas turbine (60 % efficient),
minimal transmission
losses (compared with transporting liquid fuels), high -
efficiency batteries (~ 85 %) and electric motors (~ 85 %).
