Did a 1200 km trip in mid November 2022, between Bangalore-Hubli-Karwar-Mangalore-Charmadi-Bangalore, in my EV6, spread over 3 days.

Bangalore-Hubli is pretty straightforward, nothing to comment, except one huge pothole on the Tumkur bypass flyover that can take out a car's suspension. Please be careful here.

Hubli-Karwar: 

Hubli bypass- kalghatgi- 22km 35 min. More or less perfect roads. Odd pothole here and there, can be avoided easily. 

Kalghatgi-Yellapur- 43 kms 55 min. Same road conditions, frequency of pothole gradually increases as one approaches Yellapur. 

Yellapur - Ankola - Ghats are actually in quite decent shape. Potholes and undulations at the sharp corners but can avoid easily.

Post the ghats, road is not good, with potholes every 100-200 mtrs. But can still average 50 kmph. Lots of truck traffic.

Ankola to Karwar has some sudden deviations which one has to watch out in the night. 

Departed Hubli bypass at 6.30 and reached Karwar by 9.30

Karwar to Mangalore is again pretty straightforward. Few deviations   where the 4 laning is pending, but quite easy to navigate in the day.

Mangalore-Bangalore via Charmadi ghats:

Departed Mangalore by 6 pm. Light to moderate traffic till Bantwal.

Roads significantly narrowed down at Punjalkatte and there was heavy traffic till Ujjire. Lots of cars were being very aggressive and making crazy overtakes in this narrow stretch to make up ground.

Ujjire - Charmadi - Kottigehara: The traffic reduced significantly but the narrow turns in the dark made for careful driving. Reached Kottigehara by 8.30 pm. Took a break here for some tea and snacks. Departed by 8.45pm.

Kottigehara - Mudigere - Belur - Shantigrama: Road was perfect all the way till Belur, post which there were potholes and broken roads till Hassan ring road. Reached Shantigrama by 10 pm, where we had dinner at Sri Krishna Nalapaka/Hotel Skybird, where there is a Zeon charger. The car charged up while we had dinner. 

Shantigrama - Bangalore - Very straightforward route, smooth 4 laned roads all the way barring a few diversions for flyover construction till CR Patna. Departed by 11pm and reached Bangalore by 1am.
