Not really.
Taking into account lifespan and the entire mainteinance
package, Volvo's is actually quite possibly competitively
priced.
In fact there isnt such a thing as a "hybrid engine". The bus is
powered by the combination of an electric motor and the traditional
combustion engine.
If I am not mistaken, the Sunlong's combustion engine is from
Cummins. The electric motor system is from Eaton.
So what "China make" are you talking about actually when the
systems are from USA?
Actually I meant that even though most of the parts are made in
other countries, it still bears a Sunlong badge. But since SBS
Transit has bought so many Volvo buses I wonder why Volvo didn't
offer SBS a hybrid yet. And I believe SBS had intended to obtain
hybrids for testing in 2010, if it was a demo loaned to SBS it
would already have been already returned and probably sold to some
private operators already, but SBS is still holding on to the buses
for some reason (same for RD6066L). This is what that really
puzzles me.
