Specs side by side
What owners say
i7
Overall
Mixed sentiment with a clear divide between strong appreciation for its luxury, technology, and driving experience, and significant criticism regarding its styling, market reception, and specific reliability concerns. The vehicle is consistently praised as a "luxury powerhouse" with an incredible, comfortable, and spacious interior, excellent sound systems, and a surprisingly capable and smooth driving dynamic that isolates occupants from road imperfections. However, it is frequently described as a "monumental flop" in terms of sales, leading to massive depreciation and deep discounts on new and used models.
Best version to buy
Insufficient owner data available to designate a specific best version. Commentary mentions the i7 M60 performance variant and the availability of an executive package with a large rear screen, but no consensus on a preferred trim emerges from the data.
Known issues
- Severe depreciation and poor sales reception: described as a "monumental flop," leading to deep discounts and high inventory. Frequency: very frequent.
- Exterior styling criticism: specifically the front-end design and large grilles are frequently called "hideous" and a turn-off. Frequency: very frequent.
- Electrical and mechanical reliability concerns: isolated reports of a transmission failure at 14,000 miles and an engine replacement at 32,000 miles on a 2023 model.
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.
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.
Known issues
- Major reliability and component failures: including transmission replacement, rear differential replacement, heater replacement, and high-voltage battery replacement (with a cited out-of-warranty cost of approximately $52,000).
- Software and infotainment bugs: system freezes, slow response, navigation failures, profile memory issues, charge planner glitches, Android Auto/CarPlay connectivity problems, and lack of software updates for older model years.
- Poor software support and updates: manufacturer does not update older model years to newer software versions, leaving navigation systems broken for extended periods (e.g., 8 months in Europe for 2020-2024 models). Frequency: very frequent.
