I spot one running on route 341 / 342 on the Sarjapur Ring Road, near Agara junction quite frequently in the mornings enroute to office.. The bus, for starters, does not pollute as badly as Tata, appears quite silent and does good speeds. Even interior seating looks clean and well laid out.

Spotted another one running an "Express" service on Intermediate Ring Road this morning with destination as silk board.

Yet to travel in one of these

Why is KMS written on the bus? I think its a body builder.
But knowing Corona, They build there own buses! May be they have some J V down south.
Or is it a depot name?

KMS is the body builder on Mysore road. The builder has built body on the Crimson red BS4 buses which are now running around Bangalore and earlier on the JnNurm buses too.

Spotted the new Volvo B'eleven'R...with a tag axle unlike "pusher axle" in B9R.

Recently used the rear engined AL A/C bus on tarmac service with spice jet in Chennai. From the short ride from the terminal to the airplane, felt that the pick up, ride quality, nvh levels were very good (on par with Volvo) and much better than Tata Marcopolo rear engined ones in service at Chennai airports

wow..very unique spotting. Has the B11R really launched? It looks different.

If you notice the rear tyre is steerable as the front tyres . Thats the difference which I can find . I do not know the model name though !

This model was recently shown in the auto expo as well .

This is commercially termed as 9400PX which has B11R chassis.

Whats the advantage of this setup? How does the rear steering work with the driven axle is fixed?

The rearmost wheels turn based on steering inputs. Remember, these buses all have power steering, so all that's needed are a few fluid lines, or some wires to work the hydraulic actuators. The steered axle helps in reducing the turning radius, and on the highways, helps lane changes. The direction will be opposite to the way the front tyres turn.

The propeller shaft goes over the tag axle from the rear mounted engine to the driven axle, so no problems there.

The advantage being reduced tyre wear compared to pusher axle in 9400 XL.
Pusher axle tyre wear in Volvo is atleast 25 to 30% higher than that of MB's.

The rear tyres turn (to a very slight degree) to the same direction as the front tyres at higher road speeds depending on the steering input - lane changes for instance. At lower speeds & sharp steering inputs ( turns, parking ) the 'opposite' rule applies, always. I assume this is true for CV 4 wheel steering systems as well.
