Taycan
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.
