Audi A6 Mileage

​Hey everyone, I would like your advice on restructuring my three-car garage in anticipation of a significant increase in my monthly running. I am based in Bangalore, and my current line-up is as follows: ​Audi A6 (2020) | 35,000 km driven that is used primarily for highways and family outings. It’s a brilliant machine but honestly feels highly underutilized. ​Innova Crysta GX (2019) | 1.5L km driven: The ultimate workhorse. Runs 1,500 km monthly. Split between office commutes, airport runs, and big family trips. ​Hyundai Verna (2023) | 25k km driven: Primarily used as the daily home or city runabout. ​My confusion is that from next month, my personal running will jump significantly to 2,500 km per month. Doing this in Bangalore traffic (plus routine family weekend trips) means fuel costs and driving fatigue are going to skyrocket. I want to bring an EV or a solid Plug-in Hybrid (PHEV) , but I’m considering following: ​Option 1: Replace the Audi A6 with a Premium Luxury EV. Since the A6 is not being used much, I am planning to sell it and get a high-end luxury EV (like a BMW iX1, iX3, or BYD Seal/Sealion 7) to absorb the entire 2,500 km monthly grind and family outings. ​Option 2: Retire the workhorse Innova. It has done 1.5 lakh km and I could replace it and the Audi to go for a two-EV garage, or grab a premium electric 7-seater to take over its duties. ​Option 3: Hold onto the current garage and just add one. Keep all three and buy a new mid-to-premium electric SUV like Tata Harrier EV, Mahindra XEV 9e / XEV 9S, or wait for the upcoming BYD DM-i Plug-in Hybrids. ​With 2,500 km of monthly driving entirely in Bangalore and surrounding highways, what is the smartest financial and experiential move here? Sell the underutilized luxury sedan, upgrade the high-mileage workhorse, or just expand the garage? ​Would love to hear your thoughts, especially on real-world reliability, battery degradation at high mileage, and how the current crop of premium EVs handle Bangalore's notorious infrastructure
