Just collected my new RC300h, now in Azure Blue, replacing my Sonic Red 2016 model.
First impressions are, it's noticeably quieter. There is much less 'milk-float' whine on deceleration. The car will accelerate much longer on electric, the car switching to battery power more readily in general driving.
The Mark Levinson sounds much fuller than the standard audio in the 2016 model, which wasn't poor in any respect. The Sat Nav has been improved no end, much easier to set routes etc..
Filled the tank with V-Power and looking forward to exploring the suspension and steering upgrades
