Real-world fuel efficiency of my used 530d; Fully-loaded highway drive

620 Nm and 265 PS were called upon liberally at every available opportunity to accelerate and the ZF8 was in its element as always.

BHPian d3mon recently shared this with other enthusiasts:

Odo has crossed 25K kms with small highway jaunts here and there.
Most recent one was a quick 2 day trip to Chennai with 4 on board.

Onwards journey started off well but the constant diversions (due to construction) and truck traffic meant I couldn't stretch Trie's legs. Had to drive slowly and patiently. And eventually the Chennai city traffic was also painful to navigate.

Got good FE for the first 2 hours, with smooth roads and calm cruising. Anyway with the FIRs being lodged at 130KMPH, made liberal use of the LIM (limit) function to ensure I don't go over 130.

Final stats, after navigating through the endless diversions & chennai traffic.

On the way back, decided to explore a different route via NH75 and some back roads that I knew. This route was way more fun and got us back through some lovely roads. 620NM and 265PS were called upon liberally at every available opportunity to accelerate and the ZF8 was in its element as always, never missing a beat. Truth be told, sitting at my desk, i have the itch to get a remap, but that itch goes away when I go for a long drive and experience the already insane performance, no matter the terrain or the payload

Final stats for the return.

About a km away from home, I got a notification on the iDrive about the rear right tyre pressure being low. Got down to check and indeed it was only 24PSI, vs the 40 PSI (hot) in the rest of the tyres. Further investigation showed a nail bang in the middle of the wheel tread. Anyway I had RFTs, so just carried on for the remaining km and parked safely at home. Was surprised that the TPMS (indirect) did not warn me earlier, as a 14PSI delta is quite large and the system should have been able to detect it sooner. I'll probably have to get direct TPMS sensors fitted the next time I get some tire maintenance done for better monitoring.
