FIGURE 1 // WHERE IT WEARSAudi RS
Top three failure systems, annotated from 30 failed first-time tests. Arrows point to where the defect is found on the car.
Tyres are 75% of everything that fails an Audi RS
172 inspections in a single year make the RS a modestly documented electric car in the data. Tyres cause 74.6% of its failures; tyres take 3.1× the share they take on petrol and diesel cars of the same age.
First-time test findings
The three-year picture
AT THREE YEARS OLD17.4%
RS failure rate. Petrol cars of the same age fail 8.2%.
ALL ELECTRIC CARS12.0%
All electric cars in the data.
At three years old the Audi RS fails 17.4% of the time, over the 8.2% of a petrol car the same age. Tyres cause 74.6% of its failures.
FIGURE 2 // TYRE SECTION28 certificates in 2024
The tyre that wears from the inside
Tyres take 74.6% of the defects that fail this car, 3.1× the share seen on petrol and diesel cars of the same age. The most common item in that group is "A tyre seriously damaged", recorded 28 times in 2024.
SECTION // TYRES CONCENTRATIONYear 3 crossover
Where the curve bends
The crossover with petrol happens around year 3. From there the RS's failure rate climbs faster than the petrol fleet, and the defect list explains why.

What to check
Check tyre age and tread across the full width, inner edge included. Electric cars wear tyres faster; a cheap mismatched set on a used car tells you how it was run. Have the suspension joints, bushes and springs checked on a lift. On this car it is a leading cause of failure and it is not visible from the outside. Ask when the brakes were last stripped and cleaned. Regenerative braking barely wears the pads, so discs and calipers corrode and seize instead. Ask for the full MOT history by registration on the free DVSA service: advisories are next year's failures.
3 inspection points:
✓ Tyre inner-edge wear and age
✓ Suspension joints and bushes on a lift
✓ Rear caliper drag and disc lip

Three things the data shows
- 172 inspections in 2024 make this one of the adequately-documented electric cars in the data.
- Tyres take 3.1× the share of failures they take on petrol and diesel cars of the same age.
- It ranks 68 of 81 electric cars by first-time failure rate.
LIMITS // WHAT THE INSPECTION DOES NOT TELL YOU
No battery health, no motor, no charging performance. The test covers brakes, suspension, steering, tyres, lights, visibility and structure. A car with a badly degraded battery passes as long as it stops and steers. Read this page as evidence about the chassis, not the powertrain. Cars are tested from their third year, so the newest model years are missing; every figure carries its sample size for that reason. Full methodology.
