McLaren 570

What fails its inspection

Great Britain's MOT record for the 2017 3.8 petrol. 20 of 266 tests failed, 8%.

Better than 87% of 2017 cars. The typical one fails 12%, across 926 models with enough tests behind them to say.

The defects inspectors cite

• A shock absorber damaged to the extent that it does not function or showing signs of severe leakage
• A spring or spring component fractured or seriously weakened
• A tyre cords visible or damaged
• A steering ball joint with excessive wear or free play
• A suspension pin, bush or joint excessively worn
• Emissions levels exceed default limits

Where it stands out against its peers

• Suspension: failed more often than 94% of 2017 cars — 50% of its 20 failed tests, where an ordinary 2017 car has 18%.

Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.

NHTSA's investigations are American; no European regulator publishes an equivalent record, so this section has nothing to draw on for a European car. There is no European equivalent of the service-bulletin register either.
