Corona is a Indian bus manufacturer based out of Pune. Karnataka State
Road Transport Corporation - KSRTC has introduced these Corona buses
just a few years back under its service. The AC sleeper services are
called as Ambaari.
I had seen this bus quite a few times in Bangalore and was very excited
when then launched it in the Bangalore - Mangalore route. But always
getting tickets during the weekends was a problem. And I usually book
the tickets just a few days in advance seeing my work schedule. At last
I got a chance to travel in the KSRTC Ambaari - Corona sleeper bus.
My first travel on the KSRTC Ambaari - Corona Sleeper between Bangalore
and Mangalore was completely disappointing. I had some good expectations
from the Corona sleeper since it looks like any other high end luxury
bus. The Exterior looks are excellent and paint quality is also good.
From outside you feel it as a premier luxury bus just like Volvo’s or
Mercedes. Corona is a rear engine bus with Cummins engine. Its a 2+ 1
Sleeper coach with a total 32 berths, fully air conditioned.
Coming into the bus the interior quality is very good. The curtains, bed
fabric, etc. Even better than Volvo's. Gies a royal feel when you enter
the bus. Fit and Finish inside is excellent. I would give a Excellent
rating on it. Corona being a Indian manufacturer has done a good work on
it. I loved the bed design, its curve shaped and supports your back
well. You don’t feel any rolling in the ghat section. I think it’s the
best design of Sleeper bus I had seen till now.
Also cool air was not coming and the driver had switched off the AC and
just the fan was running. When he turned on the AC again a lot of
sound was coming from the blower. Its very noisy , your sleep gets
completely disturbed. In middle of night you actually get scared by the
sudden blowing sound. It’s that bad. I don’t know whether its due to
poor maintenance or a design defect. Also there is no luggage holder to
keep small bags.. unlike other sleepers. Dash board is pretty sad.
Corona could have done it better. It looks cheap.
But hold on... All is not well. Getting on the Upper Sleeper is
difficult. Since there are no side rods to catch. Its very difficult to
catch the bus on the move. The Pillow is very hard to sleep. AC is
pathetic. There is no air circulation, a serious design problem. Single
sleeper has only 1 AC vent which can’t be turned in all direction. The
air just flows in one direction. And for double sleeper there is only 2.
Unlike regular AC buses which has 4 AC vents which can turn in all
