2021 Porsche Taycan 4s 79kwh
CarHunch analysed 287 real MOT records for the 2021 Porsche Taycan 4s 79kwh. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Porsche Taycan 4S is a solid performer on the MOT bench, with an 87.8% first-time pass rate that sits comfortably above the UK average of 80%, and only 9.1% of vehicles have ever recorded a dangerous defect—well within acceptable limits for a buyer considering one. This electric sports saloon demonstrates genuine reliability credentials in its first few years on the road.
At a median mileage of 25,641 miles for a three-year-old car, these Taycans are running well within normal expectations, and the average of just 0.16 failures per vehicle confirms they're not throwing up structural problems. The 1.2 advisories per car suggests minor wear items (brake pads, cabin filters) rather than alarm bells—so before committing to a used example, get a pre-purchase inspection focused on battery health and the electric drivetrain, since MOT data won't catch degradation there.
What to check before buying a 2021 Porsche Taycan 4s 79kwh
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
