Overall
Mixed to positive sentiment overall, with a clear distinction between praise for its luxury, comfort, and refinement, and criticism for its driving dynamics, software reliability, and platform origins. The vehicle is consistently described as a comfortable, quiet, and well-built luxury sedan with a premium interior feel, superior sound deadening, and a smooth ride. It is favorably compared to its sibling, the i4, for being more refined, spacious, and feeling like a more purposefully engineered electric vehicle.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. The M60 performance variant is mentioned but receives criticism for its handling.

Overall
Mixed sentiment with a clear divide between driving experience and ownership reliability. The vehicle is universally praised for its exceptional driving dynamics, handling, and performance, described as "the best road-legal e-car thus far," "elegant and great fun to drive," and a "very good sports car." Owners highlight its rock-stable high-speed stability, insanely good road grip, and the significant benefit of its two-speed gearbox. The instant torque and direct, responsive EV driving experience are frequently cited as major positives, with some stating it has "ruined me for gas." However, this is heavily counterbalanced by very frequent and severe criticisms regarding reliability, software, and service.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions mention various trims (4S, GTS, Turbo, Turbo S, Turbo GT) with different performance levels.
