Reliability snapshot
The current G70 7 Series (including the fully electric i7) is a recent technology flagship with limited long-term data. It uses modular turbo B-series and V8 engines alongside the electric powertrain, with extensive electronics and driver-assistance systems. As with any new flagship, the main way to protect reliability is following the service schedule, using correct-spec fluids, and keeping software current; early ownership reports are limited.
